R v Agnoletto

Unreported

Ontario Court of Justice 27 November 1998 speeding

R. v. Agnoletto

[1998] O.J. No. 6701
Ontario Court of Justice (Provincial Division) — K.P. Evans J. | November 27, 1998


Background

Philip Agnoletto was convicted of speeding after being clocked by a Muni Quip MDR-1 radar device. The officer who operated the radar testified that he was a "qualified technician" trained in July 1997 by an Ontario Provincial Police instructor. He claimed he tested the radar according to "manufacturer's specifications" using only a tuning fork test. However, during cross-examination, serious gaps in his knowledge and training became apparent.

The officer admitted he had never seen the manufacturer's manual, didn't know about other required tests, and couldn't be certain his instructor had actually used the manual during training. When asked if he would recognize the manufacturer's manual, he answered "No." This created a fundamental contradiction: how could he claim to follow manufacturer's specifications without knowing what they were?

Issues

  1. Whether the Crown proved beyond a reasonable doubt that the radar device was properly tested and functioning accurately
  2. Whether evidence of the officer's inadequate training and testing procedures raised reasonable doubt

The Radar Evidence Problem

The court found multiple fatal flaws in the Crown's evidence. First, there was no evidence that the radar was capable of measuring the speed of moving vehicles — a basic requirement for any speeding conviction. Second, the officer's qualifications were suspect: he called himself a "qualified technician" but admitted other tests "are checked by our technicians," creating an internal contradiction about his own status.

Most damaging was the officer's admission that he had never seen the manufacturer's manual. When asked how he could follow manufacturer's specifications without reading them, he could only say he "presumed" his instructor was teaching from the manual. Under further questioning, he admitted "we can't be certain of that." The court referenced the case of R. v. Milelli, which outlined numerous setup and testing procedures for the MDR-1 that this officer had never performed.

The Crown argued that simply asking questions about missing tests doesn't constitute evidence that those tests were required. However, the court disagreed, finding that the officer's contradictory testimony about his qualifications, combined with his admitted ignorance of the manufacturer's requirements, was sufficient to raise reasonable doubt about the device's accuracy.

Key Takeaway

An officer's claim to be "qualified" means nothing if they can't explain the basis of their qualifications or demonstrate knowledge of proper testing procedures.

This case shows that radar evidence can be successfully challenged by exposing gaps in the officer's training and testing procedures. If an officer claims to follow manufacturer's specifications but has never read the manual, that contradiction alone may be enough to create reasonable doubt.

R v Amyot

[1968] 2 OR 626

Ontario County Court 10 January 1968 speeding

Regina v. Amyot

[1968] 2 O.R. 626-634
Ontario Simcoe County Court — Clare, Co.Ct.J. | January 10, 1968


Background

Theodore Amyot was charged with speeding after Ontario Provincial Police Officer McCharles clocked his dark maroon vehicle at 78 and 80 mph in a 60 mph zone on Highway 400. The twist? Officer McCharles was in an airplane, using a stopwatch to time how long it took Amyot's car to travel between painted "T" markings on the highway that were exactly 1,320 feet apart. McCharles radioed down to Constable Ragot on the ground, who pulled Amyot over and charged him.

Magistrate Kennedy heard the case first and acquitted Amyot. The Crown appealed, seeking a trial de novo (essentially a complete do-over). But when the appeal came before Judge Clare on November 27, 1967, Amyot didn't show up — and that's where things got legally messy.

Issues

  1. Did the Crown properly notify Amyot of when and where his appeal would be heard?
  2. Is stopwatch evidence from an aircraft sufficient to prove speeding without proving the stopwatch's accuracy?

The Notice Problem

The Crown's notice of appeal told Amyot his case would be heard "at the County Court of the County of Simcoe at its next sittings of competent jurisdiction" — but gave him no specific date, time, or location. The court clerk later posted a general list of cases in his office and mailed Amyot a copy, but even that list didn't specify when Amyot's individual case would be called.

Judge Clare was not impressed: "a citizen served with such a notice might expect to receive some further notification as to the exact place and date for the new trial before he was again placed upon his peril." The judge found this violated the Criminal Code's requirement that proper notice be given, and ruled the court had no jurisdiction to hear the appeal. Case dismissed on a technicality.

The Aerial Speed Enforcement Evidence

Even though he lacked jurisdiction, Judge Clare analyzed the evidence anyway in case his notice ruling was wrong. Officer McCharles had three years of aerial patrol experience and personally verified the 1,320-foot distance between highway markers with a cyclometer. His stopwatch readings of 11.5 and 11.2 seconds translated to 78 and 80 mph respectively — well above the 60 mph limit.

The judge relied on English case law (Nicholas v. Penny) establishing that mechanical devices like stopwatches provide "prima facie evidence" of what they record, even without proof of accuracy. As Judge Clare noted, "any error of over three seconds in the stop-watch would be almost inconceivable" given that a legal 60 mph speed would take 15 seconds to cover the same distance. The evidence would have been sufficient for conviction.

Key Takeaway

Perfect evidence means nothing if the Crown can't properly serve you notice of your trial date.

This 1968 case shows that courts take notice requirements seriously — even when the evidence of guilt seems overwhelming, procedural fairness comes first in the criminal justice system.

R v Aransevia

[2002] O.J. No. 4891

Ontario Court of Justice 21 November 2002 speeding

R. v. Aransevia

Ontario Court of Justice — Justice R. Khawly | November 21, 2002
Ontario Court of Justice


Background

Fitz Aransevia was charged with speeding under the Highway Traffic Act. At trial, a police officer testified that he was operating a LTI Marksman 2020 laser speed measuring device. The officer stated: "I am also a trained and qualified radar and laser speed measuring officer and I was using a LTI Marksman 2020 measuring unit which is capable of measuring the speed of a moving vehicle. This was tested and found to be working by myself."

The Justice of the Peace convicted Aransevia, reasoning that he could "draw some reasonable conclusions" from the officer's testimony. The JP concluded that when the officer said he "tested" the device, this must have meant he tested it both before and after his shift on the day in question, in accordance with manufacturer specifications. Aransevia appealed this conviction.

Issues

  1. Was there sufficient evidence that the laser device was tested both before and after use?
  2. Can a trial court make reasonable inferences about testing procedures, or does this amount to speculation?

The Laser Testing Requirement

Justice Khawly examined recent Court of Appeal authority, particularly the Vancrie decision, which established that to prove a laser device was working properly, the Crown must show the device was tested both before and after use on the day in question. The court reviewed several cases where this standard was met — in each case, officers gave specific testimony like "I had tested the device prior to setting it up on that date and after taking it down and found it to be in proper working order."

In this case, however, all the Crown had was the officer's vague statement that the device "was tested and found to be working by myself." There was no evidence of when this testing occurred, what kind of testing was done, or whether it happened both before and after the speed measurement. Justice Khawly ruled that for a trial court to infer that proper before-and-after testing occurred would require "reading in evidence that is not before the Court."

Reasonable Inference vs. Speculation

The key issue was whether the Justice of the Peace could reasonably conclude that proper testing had occurred based on the officer's general statement. Justice Khawly held this crossed the line from reasonable inference into impermissible speculation. The court noted: "Just because one is an experienced officer doesn't necessarily give the trier of fact licence to read in words that are not there." The Crown's evidence simply did not establish the required foundation for laser speed measurement evidence.

Key Takeaway

Vague testimony about "testing" a laser device is not enough — the Crown must prove specific before-and-after testing procedures.

If you're facing a laser speeding charge, examine whether the officer's testimony specifically addresses when and how the device was tested. Generic statements about testing may not meet the legal standard required for conviction.

R v Arvanites

Unreported

Ontario Court of Justice 6 December 1999 speeding

R. v. Arvanites

Ontario Court of Justice Appeal
Ontario Court of Justice — Judge P. Sheppard | December 6, 1999


Background

Maria Arvanites was charged with speeding — 92 kilometres per hour in a 40 kilometre zone on March 10, 1997. The officer used radar to clock her speed and testified that she performed three tests on the radar unit: a "bob test" (later clarified as a "bulb test"), tuning fork tests, and ghost tests. During cross-examination, it emerged that there was actually a fourth test available — the "25 test button" — which the officer described but admitted she had never performed. The officer also testified that she couldn't recall seeing the manufacturer's manual and had been trained in 1992 by another officer, not by the manufacturer directly.

Arvanites testified in her own defense, claiming she wasn't speeding and that another vehicle had passed her before the officer stopped her. The justice of the peace convicted her, making some troubling comments along the way, including "I do not know. It is destroying radar, that is for sure" and dismissing radar evidence as "immaterial."

Issues

  1. Did the officer's failure to perform all available radar tests raise a reasonable doubt about accuracy?
  2. Did the justice of the peace apply the wrong legal standard for conviction?
  3. Did the justice make inappropriate comments that suggested bias?

The Real Problem: Wrong Legal Standard

The appeal court didn't need to resolve the technical radar issues because the justice of the peace made a fundamental legal error. Instead of asking whether the Crown had proven the case beyond a reasonable doubt, the justice focused on whether he could "see why the officer would commit perjury." This flips the burden of proof entirely — the test isn't whether the accused can prove the officer is lying, but whether the Crown has proven guilt to the required standard.

The justice also took inappropriate "judicial notice" of physical facts about tire squealing at different speeds, making credibility findings based on his personal beliefs rather than the evidence presented. The appeal court found no evidence in the transcript to support the conclusions the justice was drawing about vehicle behavior.

The Crown's Weak Position

The Crown argued that one radar test was sufficient if the officer was satisfied the machine was working properly, and that the officer didn't need to consult the manufacturer's manual every time. However, these arguments became irrelevant once the court identified the fundamental legal errors in the original conviction.

Key Takeaway

Even solid technical defenses can be overshadowed when the judge applies the wrong legal standard entirely.

This case shows that while challenging radar evidence on technical grounds can be effective, the most important thing to watch for is whether the justice is applying the correct burden of proof. If a judge starts talking about why you would lie rather than whether the Crown has proven its case, that's a reversible error.

R v Baren

[1996] O.J. No. 5353

Ontario Court of Justice (Provincial Division) 9 February 1996 speeding

R. v. Baren

[1996] O.J. No. 5353
Ontario Court of Justice (Provincial Division) — Rosemay Prov. J. | February 9, 1996


Background

Lianne Baren was caught speeding at 75 km/h in a 40 km/h zone — a whopping 35 km/h over the limit. She didn't show up to her original trial date but was represented by an agent, and got convicted. Baren appealed and appeared in person before Judge Rosemay to tell her side of the story.

Her explanation was compelling: she felt a migraine headache coming on and knew from experience that she had about five minutes to get medication before she'd lose her vision and become unable to drive safely. Her boyfriend lived nearby and had her medication (Imitrex tablets), so she sped to get there before the migraine fully hit. A doctor's letter confirmed she was under medical care for migraines and used Imitrex as needed.

Issues

  1. Can the defence of necessity apply to Highway Traffic Act speeding charges, which are absolute liability offences?
  2. Did Baren's circumstances meet the legal test for necessity?

The Defence of Necessity

The Crown argued that speeding under the Highway Traffic Act is an absolute liability offence, meaning no defences should be available — you either did it or you didn't. They cited case law suggesting necessity doesn't apply to these types of charges. But Judge Rosemay disagreed.

The court found that Baren's situation created a genuine emergency. She faced "dire consequences" if she continued driving without getting her medication — specifically, she would lose her vision and become a danger to herself and others. The judge was satisfied that the defence of necessity did apply, even to an absolute liability speeding offence, because Baren was trying to prevent a greater harm (a serious accident caused by impaired vision).

The medical evidence was crucial. The doctor's letter, written just two days after the incident, confirmed Baren's ongoing migraine condition and her prescribed medication, lending credibility to her explanation.

Key Takeaway

Even absolute liability traffic offences can sometimes be defeated by the defence of necessity in truly emergency situations.

If you're facing a traffic charge and believe you had no choice but to break the law to prevent a greater harm, document everything immediately and get medical or other professional evidence to support your claim. The defence is rare and the bar is high, but this case shows it's not impossible.

R v Bigioni

Unreported

Ontario Provincial Offences Court 17 September 1986 speeding

R. v. Bigioni

[1986] O.J. No. 2753
Ontario Provincial Offences Court — Sturch J.P. | September 17, 1986


Background

At 1:01 a.m. on June 21, 1986, P.C. Anthony Ironside was parked in an unmarked car on Warden Avenue in Scarborough, watching for speeders. He observed Denis Bigioni's Ford travelling southbound in the second of two lanes, appearing to speed. Ironside pointed his hand-held Muniquip radar device at the vehicle and got a reading of 94 km/h in a posted 60 km/h zone.

Ironside stopped the vehicle and identified Bigioni as the driver. The weather was clear, roads were dry, and Ironside testified that he was qualified in radar use and had "tested" the radar unit at the start of his shift, at the location, and after finishing his shift at 3:00 a.m., finding it "in accurate working order." Bigioni was charged under Highway Traffic Act section 109 and pleaded not guilty.

Issues

  1. Whether the Crown proved beyond a reasonable doubt that the radar device was capable of accurately measuring speeds
  2. Whether the officer's evidence about testing the radar unit met the legal requirements for admissibility

The Radar Evidence Requirements

Bigioni, representing himself, argued that the Crown failed to prove the radar device's accuracy. He cited several cases, including Regina v. O'Reilly from Alberta, which established that radar readings can only be accepted as evidence when: (a) the instrument is operated by someone trained in its operation, and (b) the operator gives evidence that he conducted an "approved test" of the instrument and that the test satisfied him the instrument was operating properly and capable of accurately measuring speeds.

The defence pointed out critical gaps in the Crown's evidence. While Ironside claimed to be "qualified," there was no evidence about his specific training. More importantly, while he said he "tested" the unit, there was no evidence about what type of tests he conducted (tuning fork or otherwise), whether those tests were approved in the operating manual for that particular device, or any details about the testing procedure. The defence cited Ontario Provincial Offences Appeal Court decisions that followed the O'Reilly standard, including a recent case involving another Bigioni where identical evidence was found insufficient on appeal.

The Court's Decision

Despite the defence arguments, Justice of the Peace Sturch convicted Bigioni. The court reasoned that the officer's testimony that he tested the machine and found it working accurately was sufficient, and that it wasn't necessary for the officer to detail his testing methods every time. The court found there was a prima facie case and imposed a $40 fine with 30 days to pay.

This decision appears to conflict with the higher court authorities cited by the defence, which required more detailed evidence about testing procedures and operator qualifications.

Key Takeaway

Radar evidence requires proof of proper testing and operator qualifications — vague claims about being "trained" and having "tested" the device may not be enough.

While this particular court accepted minimal evidence, the cases cited by the defence suggest that challenging radar evidence on the basis of insufficient proof of testing procedures and operator qualifications can be a viable defence strategy, especially when the officer provides only conclusory statements without specific details.

R v Bland

(1975), 6 O.R. (2d) 54

Ontario Court of Appeal 20 December 1974 speeding

Regina v. Bland

(1975), 6 O.R. (2d) 54
Ontario Court of Appeal — Jessup, Arnup and Dubin JJ.A. | December 20, 1974


Background

Milton Bland was driving westbound on Highway 7 through Omemee when Police Constable F.L. Prior spotted him leaving the village. Prior followed for four and a half miles, then clocked Bland's vehicle at 95 mph over a seven-tenths-mile stretch from Reaboro to the 9th concession of Ops Township. Bland was charged with driving 90 mph in a 60 mph zone under section 82(16) of the Highway Traffic Act.

At trial, Prior testified about the speed but never mentioned what the speed limit actually was on that stretch of highway. He also admitted he had no personal knowledge about his speedometer's accuracy — just a card in his cruiser saying it had been checked by radar that day. Despite these gaps, the Justice of the Peace convicted Bland. The conviction was upheld on appeal to the Provincial Court, then appealed again to the Court of Appeal.

Issues

  1. Can police speedometer evidence support a conviction without proof of the speedometer's accuracy?
  2. Can a court convict for speeding without any oral evidence of the speed limit?

Speedometer Evidence Without Accuracy Proof

The Court of Appeal firmly rejected the idea that police must prove their speedometer's accuracy before using it as evidence. Following the English case Nicholas v. Penny, Justice Arnup ruled that speedometer readings over a measured distance provide prima facie evidence of speed — meaning it's presumed accurate unless the defence proves otherwise. The officer's testimony that his speedometer showed a steady 95 mph over seven-tenths of a mile was enough to establish Bland was speeding, even without technical evidence about calibration.

This directly overruled an earlier Ontario case, R. v. Thibodeau, which had required proof of speedometer accuracy. The Court of Appeal noted that if defendants want to challenge speedometer accuracy, they can cross-examine the officer or call their own evidence — but the Crown doesn't have to prove accuracy as part of its case.

Judicial Notice of Speed Limits

Even though the prosecutor forgot to ask about the speed limit, the Court found this didn't matter. Speed limits are set by regulation under section 82(11) of the Highway Traffic Act. Under sections 5 and 10(2) of Ontario's Regulations Act, published regulations must be judicially noticed — meaning judges are legally required to recognize them even if no one mentions them in court.

The Court examined R.R.O. 1970, Reg. 429 and determined the relevant stretch of Highway 7 had a 60 mph limit. Since regulations are automatically "noticed" by law, the speed limit was legally established without any testimony.

Key Takeaway

Police speedometer evidence is presumed accurate unless you prove otherwise, and speed limits don't need to be proven in court.

If you're defending a speeding charge, don't expect the Crown to prove their speedometer works — that burden is on you. Focus your defence on challenging the officer's observations or the speedometer readings themselves, not demanding calibration certificates.

R v Bourne

[2001] O.J. No. 2869

Ontario Court of Justice 15 June 2001 speeding

R. v. Bourne

[2001] O.J. No. 2869
Ontario Court of Justice — Justice Karswick | June 15, 2001


Background

Tracy Bourne was caught speeding and ticketed under section 128 of the Highway Traffic Act. Her speed was measured using an L.T.I. 20-20 Marksman Laser Speed Detection Device (L.S.D.D.). The officer operating the device was properly qualified and had performed all four manufacturer-recommended tests before using it: the "self-test", "display test", "scope test" and "distance-velocity test". Both parties agreed the officer was qualified and the device had been tested according to manufacturer instructions.

However, there was one thing missing. The officer had not performed an independent verification test by comparing the laser device's readings against a conventional radar device on moving vehicles. Bourne appealed her conviction, arguing this missing test made the laser evidence unreliable.

Issues

  1. Was the evidence of the laser device's accuracy and reliability adequate without independent verification testing against radar?
  2. What standard of testing is required to make laser speed detection evidence admissible in court?

The Laser Evidence Battle

Justice Karswick had to navigate conflicting decisions from other Ontario judges about laser evidence. In R. v. Vancrey, the Court of Appeal had upheld a conviction where the officer did perform comparison testing between the laser and radar devices (even though it was done 3-4 weeks before the traffic stop). The Court of Appeal found this "radar test" provided "the independent guarantee of the accuracy of the particular laser unit to measure the speed of a moving vehicle."

But in R. v. Wong, Justice O'Hara had found that without dynamic testing against radar, "there is no adequate testing of the error trapping mechanisms" built into laser devices. He required comparison testing as part of proving reliability.

A third judge, Justice Pockele in R. v. Mukasa, had gone the opposite direction, ruling that laser technology was no longer "new and novel" and didn't require comparison testing with radar. Justice Karswick firmly rejected this approach, noting that Justice Pockele had no scientific or technological evidence before him to support such broad conclusions about laser reliability.

The Court's Decision

Justice Karswick sided with the Court of Appeal's approach in Vancrey and Justice O'Hara's analysis in Wong. He ruled that laser evidence requires independent verification through comparison testing with conventional radar devices within a reasonable time period. The manufacturer's four tests alone are not sufficient because they don't test the "error trapping mechanisms" that prevent unreliable speed measurements.

Since the Crown failed to present any evidence of comparison testing between the laser device and radar, the laser evidence was unreliable and inadmissible.

Key Takeaway

Laser speeding tickets can be successfully challenged if the officer didn't perform comparison testing against radar devices.

If you're facing a laser-based speeding charge, ask the Crown whether the officer conducted independent verification by testing the laser device against a conventional radar unit on moving vehicles. If they can't prove this testing happened within a reasonable time before your ticket, the laser evidence may be inadmissible and your charge should be dismissed.

R v Brewer

Unreported

Ontario Provincial Court 19 May 1988 speeding

R. v. Brewer

[1988] O.J. No. 2531
Ontario Provincial Court — Lampkin Prov. Ct. J. | May 19, 1988


Background

Christopher Brewer was charged with speeding 90 km/h in a posted 60 km/h zone on September 4, 1986, on The Queensway South in Georgina. Police Officer Whittington used a hand-held Muni Quip radar unit (model TC 3) while parked at a Mac's Milk Store. The officer testified that he tested the radar using internal buttons and a tuning fork, spotted Brewer's grey pickup truck travelling at high speed, and obtained the radar reading that led to the charge.

At trial, Officer Whittington initially testified that he was "trained as a new officer by an experienced officer" and was "taken out in a vehicle and shown the operation of a radar." However, defence counsel R. Dullege subjected the officer's qualifications to intense cross-examination, revealing significant gaps in his training and knowledge of proper radar operation.

Issues

  1. Was the police officer properly qualified to operate the radar device?
  2. Was the radar testing procedure conducted according to manufacturer specifications?

The Qualification Challenge

Under cross-examination, Officer Whittington admitted he had never seen anything from the manufacturer, never read the radar manual, and couldn't confirm whether his testing procedures were correct. When testing the radar with a tuning fork, he struck it on the steering wheel and held it "directly in front of the radar" — but couldn't say whether this was the manufacturer's recommended procedure. Most damaging, he admitted there was no evidence that the officer who trained him was qualified to operate radar either.

The trial Justice of the Peace initially accepted the officer's evidence, reasoning that "without evidence to the contrary" he would assume the officer was qualified. However, on appeal, Judge Lampkin found this reasoning flawed. The judge extensively quoted from "The Law on Speeding and Radar" by Manraj and Haines, noting that hand-held radar units are "the most difficult to control of all types of radar units" and require careful, proper training and testing procedures.

Crucially, the court found that once the officer's qualifications were "seriously questioned and attacked under cross-examination," the Crown failed to prove he was a qualified radar operator. The officer "could not really confirm that what he did to use that radar unit was according to the manufacturer's specifications."

Key Takeaway

A police officer's claim to be "qualified" isn't enough if cross-examination reveals they lack proper training or knowledge of manufacturer specifications.

This case shows the power of thorough cross-examination in radar cases. When an officer admits they've never read the manual, don't know proper testing procedures, and can't confirm their trainer was qualified, their "qualification" becomes meaningless. The appeal was allowed and Brewer's conviction was overturned.

R v Cannon

Unreported

Ontario Court (Provincial Division) 18 February 1999 speeding

R. v. Cannon

Ontario Court (Provincial Division)
Before the Honourable Judge R.E. Bogusky | February 18, 1999, at Newmarket, Ontario


Background

Doug Cannon was charged with speeding under section 128 of the Highway Traffic Act. The police used a laser speed-measuring device to catch him, but there was a significant gap in the testing schedule. The device had been tested with radar five months before the alleged offence and four months after. This created a nine-month window where the laser's accuracy wasn't verified against a known standard.

The case came to court as an appeal from a Justice of the Peace decision. Defence counsel B. McLeod argued that nine months between accuracy tests was far too long to establish that the device was working properly on the day Cannon was allegedly speeding.

Issues

  1. How frequently should laser speed-measuring devices be tested to ensure accuracy?
  2. Was a nine-month gap between tests sufficient to undermine the reliability of the speed reading?

The Periodic Testing Requirement

The court examined the Tamon decision, which had established that speed-measuring devices should be "tested periodically" against more common speed-measuring devices like radar. However, the Tamon decision didn't specify exactly what "periodically" meant — whether it was daily, weekly, monthly, or some other timeframe.

Crown counsel argued that the testing was sufficient, noting that laser technology is sophisticated and reliable. The defence countered that nine months was simply too long, especially when the device was being used daily. Defence pointed out that if something is used daily but only tested twice per year — with gaps of several months — there's no way to know if it was working properly during the untested period.

Judge Bogusky noted that while police departments had started testing laser devices with radar following his Tamon decision, they were doing so "quite infrequently." The court found that for a device used on a daily basis, testing only every several months was inadequate to establish ongoing accuracy.

Key Takeaway

Large gaps in device testing can successfully challenge the reliability of speed-measuring evidence.

If you're facing a laser speeding charge, ask the Crown to produce evidence of when the device was last tested and calibrated. Gaps of several months between accuracy tests may be grounds to argue the speed reading is unreliable.

R v Chair

[2015] ONCA 868

Ontario Court of Appeal 9 December 2015 speeding

R. v. Chair

2015 ONCA 868
Court of Appeal for Ontario — Doherty, Pepall and Tulloch JJ.A. | December 9, 2015


Background

Wai-On Chair got tagged for speeding by the Regional Municipality of York. The officer used a radar device to clock Chair's speed, and importantly, the officer tested the radar gun both before and after using it, following the procedure set out in the manual. The officer was also a qualified operator of the device. At trial, the Justice of the Peace accepted this evidence and convicted Chair.

Chair appealed to a judge, and Justice Gorewich of the Ontario Court of Justice set aside the conviction and ordered a new trial. The judge found that the Justice of the Peace had "erred in law by making a finding on the facts that he was not entitled to make." The Crown then appealed that decision to Ontario's highest court.

Issues

  1. Was the evidence of proper testing and qualified operation sufficient to establish a prima facie case for radar accuracy?
  2. Should courts create a presumption of accuracy for radar gun readings?

The Radar Evidence Standard

The Court of Appeal relied heavily on R. v. Bigioni, a 1988 case that established the standard for radar evidence. Under Bigioni, if you can show that: (1) the officer tested the device before and after use according to the manual, and (2) the officer was qualified to operate it, then you've made out a "prima facie case" — meaning the evidence is sufficient unless the defence can poke holes in it.

Here, there was clear evidence of both elements. The trial judge accepted that evidence, which under Bigioni was enough to prove the case. The appeal judge was wrong to overturn the conviction, because the Justice of the Peace was absolutely entitled to make findings based on that evidence.

The Court of Appeal pointedly noted that "nothing in the subsequent case law should be taken as diminishing" the authority of Bigioni. This was a shot across the bow to lower courts that might be getting too demanding about radar evidence.

Key Takeaway

Radar evidence doesn't require perfection — just proper testing by a qualified operator.

If you're fighting a radar ticket, don't expect the Crown to produce engineering manuals or calibration certificates. Focus your defence on whether the officer actually followed testing procedures or was properly trained, not on demanding more technical evidence than the law requires.

R v Cormier

[2008] OJ No 4964

Ontario Court of Justice 20 November 2008 speeding

R. v. Cormier

[2008] O.J. No. 4964
Ontario Court of Justice — G.J. Griffin J. | November 20, 2008


Background

On October 14, 2007, Constable Darren Heasman of the Stirling Rawdon Police Service was conducting radar enforcement on Belleville Road. Using his Genesis II Spectre directional radar in opposite direction mode, he clocked Kimberleigh Cormier's southbound vehicle traveling between 86 and 94 km/h in a posted 50 km/h zone. Using his discretion, he issued her a ticket for the lower speed of 79 km/h.

At trial before Justice of the Peace Cureatz on May 12, 2008, Cormier was convicted and fined $160.50. Her lawyer argued that the officer had failed to follow the radar manufacturer's mandatory testing procedures, making the speed reading unreliable. The Justice of the Peace rejected this argument, taking what he called "a broader view" of the testing requirements.

Issues

  1. Did the investigating officer properly follow the manufacturer's mandatory testing procedures for the radar device?
  2. Can a court ignore or modify the manufacturer's explicit requirements for radar operation?

The Radar Manual Requirements

During cross-examination, the officer was confronted with a crucial passage from the Genesis II Directional User and Installation Manual. The manual clearly stated: "In addition to this road test, as part of the tracking history for any violation in which enforcement action is to be taken, it is a mandatory requirement that there be this correlation between the patrol speed of the police vehicle and the patrol speed displayed on the radar unit at that time. Without this correlation no enforcement action shall be taken."

The officer admitted he had not performed this correlation test at the time of the violation. His position was that testing the radar earlier in the day at 1:30 p.m. and later at 5:30 p.m. was sufficient compliance with the manufacturer's requirements. He testified that during the actual traffic stop, he was "focusing on the investigation" and operating in opposite direction mode, not same direction mode.

The Justice of the Peace accepted this interpretation, ruling that the instrument had been "tested adequately and correlated throughout the day." However, Judge Griffin found this reasoning fundamentally flawed, stating it was not open to the Justice of the Peace "to second guess the manufacturer's mandatory requirement."

Key Takeaway

Courts cannot ignore or water down the manufacturer's explicit mandatory requirements for radar operation — if the manual says "no enforcement action shall be taken" without a specific test, that means exactly what it says.

This case shows that even seemingly minor technical requirements can be the foundation of a successful defence. The officer's failure to perform one specific correlation test at the time of the violation was enough to overturn the entire conviction, despite proper testing earlier in the day.

R v Cuccarolo

[2009] ONCJ 593

Ontario Court of Justice 24 November 2009 speeding

R. v. Cuccarolo

2009 ONCJ 593
Ontario Court of Justice — Justice M.J. Epstein | November 24, 2009


Background

Bruno Cuccarolo was driving his 2008 BMW on Highway 401 near Cambridge on July 7, 2007, when Constable Collishaw clocked him at 140 km/h in a 100 km/h zone using a Laser Atlanta speed detection device. She was positioned on the shoulder observing three lanes of oncoming traffic when Cuccarolo's vehicle caught her attention for clearly exceeding the speed limit. The laser reading showed 140 km/h at a distance of 135.21 metres, with no other vehicles between the officer and Cuccarolo's BMW.

Constable Fisher, operating a chase vehicle 50 metres down the highway, received the radio transmission and pulled behind Cuccarolo's vehicle to make the traffic stop. At trial, Cuccarolo testified that he was travelling at the speed limit and claimed there was a car identical to his ahead of him that must have been the actual target. The Justice of the Peace convicted him, and Cuccarolo appealed, challenging the officer's qualifications, the device testing procedures, and the sufficiency of the trial judge's reasons.

Issues

  1. Was Constable Collishaw properly qualified to operate the laser device and did she test it correctly?
  2. Did the Justice of the Peace misapprehend the evidence or provide inadequate reasons?
  3. Was there sufficient evidence to support the conviction?

The Laser Evidence Challenge

Cuccarolo's agent argued that Constable Collishaw wasn't properly trained on the Laser Atlanta device and had conducted the required tests incorrectly. The officer had originally been trained on a different laser device in 1998 but was retrained in November 2006. She testified that during her retraining, she learned about the Laser Atlanta Speed Laser and received the manufacturer's manual.

The defence challenged three specific tests: the Horizontal Sight Alignment Test (arguing the target was 47 metres away instead of exactly 45 metres), the Range Accuracy Test (claiming she only did three tests instead of six), and the Light Segment Test (misunderstanding the display requirements). Justice Epstein found all these challenges meritless. The manufacturer's specifications required the target to be greater than 45 metres away, making 47 metres compliant. The officer had actually performed six tests total (two distances on three separate occasions), and the Light Segment Test was correctly interpreted as a single-step process.

The Credibility Battle

The real issue came down to credibility. Cuccarolo claimed he had his cruise control set at 100 km/h and could observe an identical BMW ahead of him with alloy rims, but somehow failed to notice Constable Fisher pulling out with emergency lights and following him for over a kilometre. The Justice of the Peace found this testimony implausible — if Cuccarolo could observe vehicles around him in such detail, including seeing through gaps in tractor trailers to spot police officers, how could he miss a police cruiser directly behind him with flashing lights?

Key Takeaway

Technical challenges to laser evidence rarely succeed when the officer followed proper procedures, and implausible testimony about mistaken identity won't save you.

Courts will closely examine whether police properly tested their equipment, but minor deviations from manufacturer specifications (like using a 47-metre target instead of exactly 45 metres) won't invalidate the evidence. More importantly, if your defence relies on claiming the officer targeted the wrong vehicle, you need a credible explanation for why you didn't notice being followed by a police car with flashing lights.

R v Dattomo

2009 ONCJ 539

Ontario Court of Justice 30 October 2009 speeding

R. v. Dattomo

2009 ONCJ 539
Ontario Court of Justice — Justice of the Peace Kenneth W. Dechert | October 30, 2009


Background

At 2:05 a.m. on February 22, 2009, Pietro Dattomo was driving his white Ford pickup truck westbound on Speers Road in Oakville when Officer Gerry Prevost clocked him at 75 km/h in a 60 km/h zone using a Genesis VP Directional handheld radar device. Prevost was parked about 20 metres south of the roadway in a private drive, facing north with what he described as "a clear view of both eastbound and westbound lanes."

Dattomo was charged under section 128 of the Highway Traffic Act, though the prosecution reduced the offence to 70 km/h in a 60 km/h zone. He pleaded not guilty and went to trial, represented by legal counsel who challenged the reliability of the radar evidence.

Issues

  1. Whether the prosecution proved all elements of the speeding offence beyond a reasonable doubt
  2. Whether the radar device was operating accurately and being operated properly at the time of the alleged offence

The Radar Evidence Challenge

The defence attacked Officer Prevost's radar procedures on several fronts. Most notably, during cross-examination, Prevost admitted he couldn't name the manufacturer of the Genesis VP device he was using, and that while he'd been trained on radar generally since 1975, he'd only received training on this specific handheld device in February 2008 — making it "fairly new" to him and the police service.

The defence also challenged Prevost's interference testing methodology. The officer had conducted interior and exterior "sweeps" of his police vehicle to check for interference, but he'd set the radar's sensitivity to maximum (level 5, described as going "out to infinity") even when testing inside the confined space of his cruiser. Defence counsel argued this made no sense and suggested the testing was flawed.

However, Justice of the Peace Dechert applied the legal standard from R. v. Vancrey and D'Astous v. Baie Comeau, which requires the Crown to prove: (1) the operator was qualified, (2) the device was tested before and after operation according to manufacturer's instructions, and (3) the device was found to be accurate. The court found Prevost's training sufficient, noted he'd tested the device at 1:30 a.m. and 2:20 a.m. according to manufacturer's procedures (with both tests showing "pass"), and concluded there was no evidence the sensitivity setting during interior testing actually compromised the results.

Key Takeaway

Attacking an officer's general unfamiliarity with equipment isn't enough — you need evidence that specific procedures were actually wrong or that the device malfunctioned.

While Dattomo's counsel raised legitimate questions about the officer's expertise and testing methodology, they couldn't point to any evidence that these issues actually affected the accuracy of the speed reading. The court emphasized that speculation isn't sufficient to raise reasonable doubt about radar reliability.

R v DiGiuseppe

Unreported

Ontario Court of Justice - Provincial Division 14 November 1991 speeding

R. v. DiGiuseppe

[1991] O.J. No. 2514
Ontario Court of Justice - Provincial Division — Fraser Prov. Div. J. | November 14, 1991


Background

Dino DiGiuseppe was charged with speeding after being clocked by radar equipment operated by a police officer. At trial, the Crown presented evidence that the radar equipment was tested before and after measuring the defendant's speed using tuning forks. The radar operator testified that the equipment was working accurately and that it was found to be working accurately after the testing.

DiGiuseppe appealed his conviction, arguing that the Crown failed to establish a proper foundation for the radar evidence. Specifically, he claimed the Crown hadn't proven that the tuning forks themselves were accurate and suitable for testing the radar equipment.

Issues

  1. What evidence must the Crown present to establish the accuracy of radar equipment?
  2. Is it sufficient to prove the radar worked accurately, or must the Crown also prove the testing devices themselves were accurate?

The Radar Accuracy Requirements

The court dismissed the appeal, but not before clarifying an important principle about radar evidence. Fraser J. ruled that the Crown was only required to prove that the radar equipment was tested before and after measuring the defendant's speed, and that it worked accurately during those tests.

Crucially, the court referenced two key precedents: R. v. Bourque and R. v. Meyer. In Bourque, the court established that radar is an instrument which accurately measures the speed of moving vehicles, and operators don't need to testify that "radar is an instrument." The court noted that if it's necessary to prove the accuracy of tuning forks, then surely it becomes necessary to prove the accuracy of whatever devices are used to measure or test those forks — creating an "impossible evidentiary treadmill."

Key Takeaway

The Crown doesn't need to prove that tuning forks themselves are accurate — only that the radar equipment tested accurately when the tuning forks were used.

For self-represented defendants, this means you can't simply challenge radar evidence by questioning whether the tuning forks were properly calibrated. The court will accept that tuning forks are reliable testing devices, and you'll need to find other weaknesses in the Crown's case to mount a successful defence.

R v Doroz

[2011] ONCJ 281

Ontario Court of Justice 30 May 2011 speeding

R. ex rel. City of Toronto v. Doroz

2011 ONCJ 281
Ontario Court of Justice — Justice Libman | May 30, 2011


Background

Bartosz Doroz was caught speeding 57 km/h in a 40 km/h zone. At trial, the prosecutor agreed to let him plead guilty to the reduced speed of 50 km/h in a 40 km/h zone, which carried a set fine of $25. But Justice of the Peace Anstey had other ideas. She knew about the Winlow case from the Court of Appeal, which said judges can't reduce speeding fines below the amounts set out in section 128(14) of the Highway Traffic Act. So instead of imposing the $25 fine, she suspended Doroz's sentence entirely — meaning he paid nothing.

The prosecutor objected, pointing out that Winlow said there's no jurisdiction to reduce fines. The justice of the peace's response? 'You like Mr. Winlow, I say I trump him.' The City of Toronto appealed, arguing that suspended sentences for speeding tickets aren't legally available.

Issues

  1. Can a court impose a suspended sentence for a speeding offence, given that Winlow prohibits reducing set fines?
  2. Do speeding fines qualify as 'minimum penalties' that trigger relief under section 59 of the Provincial Offences Act?
  3. Was it appropriate to suspend the sentence in this specific case?

The Minimum Penalty Analysis

Justice Libman ruled that speeding fines are minimum penalties, even though they're calculated by a mathematical formula. His reasoning: every person guilty of the same speeding offence gets the identical fine — it can't be higher or lower than the set amount. In Doroz's case, everyone who speeds 10 km/h over the limit pays exactly $25, 'no more, no less.' This creates what he called 'a fixed penalty where the minimum and maximum coincide.'

The judge relied heavily on R. v. Dilorenzo, where the Court of Appeal found that a three-year licence suspension was a minimum penalty even though it wasn't expressed as 'not less than three years.' If a penalty is fixed at a specific amount with no discretion to vary it, it's effectively a minimum penalty that can trigger section 59(2) relief.

Section 59(2) of the Provincial Offences Act allows courts to either impose a fine 'less than the minimum or suspend the sentence' when exceptional circumstances make the minimum penalty unduly oppressive. The word 'or' is crucial — suspension is an alternative form of relief, not a reduction of the fine amount.

The Process Problem

While Justice Libman agreed that suspended sentences are legally available for speeding, he found that Justice of the Peace Anstey made serious procedural errors. She proceeded directly to sentencing without allowing the parties to make submissions as required by section 57(1) of the Provincial Offences Act. More importantly, she imposed the suspended sentence simply to circumvent Winlow, not because exceptional circumstances existed. The judge emphasized that section 59(2) relief requires 'exceptional circumstances' where imposing the fine 'would be unduly oppressive or otherwise not in the interests of justice' — a very high standard.

Key Takeaway

Courts can suspend sentences for speeding tickets, but only in truly exceptional circumstances — not as a routine way around set fines.

This case establishes that while Winlow prevents fine reductions, suspended sentences remain available under section 59(2) for defendants who can prove exceptional hardship. However, courts must follow proper procedure and apply the stringent test, making suspended sentences rare exceptions rather than common alternatives to paying speeding fines.

R v Ege

Unreported

Ontario Court of Justice 2 October 2001 speeding

R. v. Abdullahi Ege

Ontario Court of Justice — Justice M. H. Kelly | October 2, 2001
Ontario Court of Justice, Toronto


Background

Abdullahi Ege was charged with speeding 146 km/h in what appears to be a posted speed zone on Eglinton Avenue near Brimley Road in Scarborough. Officer Hougerdyke testified that he was traveling eastbound when he observed a green Lumina cab going westbound that appeared to be speeding. The officer made a U-turn, lost sight of the vehicle, then crested a hill and activated his radar device (called "the Hawke") when he regained visual contact. At 100 meters away, the radar recorded a speed of 146 km/h.

Ege was convicted at trial before Justice Tivey in provincial offences court. His agent, Mr. Higgins, appealed the conviction, arguing that the Crown failed to prove the radar device was operating properly and that there were credibility issues with the officer's evidence about losing and regaining sight of the vehicle.

Issues

  1. Did the Crown prove beyond a reasonable doubt that the radar device was operating according to manufacturer specifications?
  2. Was there sufficient evidence to support the conviction given the officer's admissions about losing sight of the target vehicle?

The Radar Evidence Problem

The case turned on what Officer Hougerdyke actually knew about his radar device. Under cross-examination, the officer's evidence "started to unravel." He admitted he had never seen the actual manufacturer's manual for the Hawke radar device — only a small booklet provided by his supervisor that was "copyrighted by the force." When asked about the device's distance limitations, operating range, and minimum speed differential requirements, the officer repeatedly answered "I don't know."

Most damaging was the officer's admission that he had no idea what the original manufacturer's specifications were, yet he testified the device was "capable of accurately measuring speeds" — an opinion the court found he was not qualified to give as he had never been qualified as an expert in electronics or radar technology. The defence successfully argued this was improper opinion evidence from an unqualified witness.

Justice Kelly found the Agnoletto case persuasive, noting that an officer cannot stand before the court as a qualified technician if he testifies he follows manufacturer specifications but has never actually seen the manufacturer's manual. The court concluded there was insufficient evidence that the radar device was operating according to proper specifications.

Key Takeaway

The Crown must prove radar devices are operating according to manufacturer specifications, not just police force procedures.

If an officer admits under cross-examination that he doesn't know the actual manufacturer requirements for the radar device, this can create reasonable doubt about whether the device was operating properly, even if the officer says he "tested" it according to his training.

R v Ell

Unreported

Ontario Court of Justice 11 June 2012 speeding

R. v. Ell

Court File No.: Halton 3785796A
Ontario Court of Justice — Justice R.J. LeDressay | June 11, 2012


Background

On March 12, 2010, Sklyar Ell was driving southbound on Tremaine Road in Milton when Officer Hanowski clocked him at 98 km/h in a 60 km/h zone using a Lidar Laser Truespeed 20/20 device. The officer was qualified to operate the device and had been re-qualified as recently as April 2011. He tested the laser device both before and after the traffic stop and found it to be working properly according to the manufacturer's instructions.

But there was a problem with one of the required tests. For the Fixed Distance Zero Velocity Test, Officer Hanowski needed to measure the device's accuracy at exactly 50 meters. Instead of measuring this distance himself, he relied on information from Police Constable Ivey, who had told him the distance was 50 meters and had marked it off at the police station. Ell was found guilty at trial and appealed, arguing this hearsay evidence made the laser readings inadmissible.

Issues

  1. Does an officer's reliance on hearsay evidence about the 50-meter test distance undermine the admissibility of laser speed readings?
  2. What level of evidence is required to establish the proper functioning of speed measuring devices?

The Hearsay Evidence Ruling

Justice LeDressay ruled that Officer Hanowski's reliance on his colleague's measurement was perfectly acceptable. The court found that police officers routinely rely on hearsay evidence when operating technical equipment — from training manuals to calibration information to procedural instructions. The judge compared it to an impaired driving investigation where an officer relies on calibration stickers showing a breathalyzer was properly maintained by a qualified technician.

The court emphasized that the information came from "a reliable and trustworthy source" — a fellow police officer who had measured and marked the distance at the station. Officer Hanowski had seen and used these markings himself when conducting the test. The fact that he didn't personally measure the 50 meters didn't invalidate his professional opinion that the device was working properly.

Importantly, there was no contradictory evidence challenging the accuracy of the 50-meter measurement. The court referenced R. v. Chow, noting that hearsay evidence can be both admissible and given significant weight when it demonstrates "circumstantial guarantees of trustworthiness and accuracy" and no competing evidence exists.

Key Takeaway

Police officers can rely on reliable hearsay evidence when testing speed detection equipment, and you need contradictory evidence to challenge their conclusions.

Simply arguing that an officer relied on information from colleagues or manuals won't make laser evidence inadmissible. To successfully challenge speed detection evidence, you need to present actual contradictory evidence about the device's accuracy or testing procedures, not just point out that some information came from hearsay sources.

R v Fazlic

[2009] O.J. No. 1802

Ontario Court of Justice 12 February 2009 speeding

R. v. Fazlic

[2009] O.J. No. 1802
Ontario Court of Justice — K.G. Lenz J. | February 12, 2009


Background

Salih Fazlic was charged with speeding under section 128 of the Highway Traffic Act. At trial, a Justice of the Peace convicted him based on radar evidence from a police officer. Fazlic appealed the conviction to the Ontario Court of Justice, represented by counsel M. Riddell. The Crown was represented by I. Lagden.

The case turned on a critical issue: whether the police officer properly tested the radar device according to the manufacturer's specifications before using it to clock Fazlic's speed. This wasn't just a technicality — it goes to the heart of whether radar evidence can be trusted in court.

Issues

  1. Did the Justice of the Peace correctly assess the evidence regarding the radar device testing?
  2. Was the accuracy and reliability of the radar device proven beyond a reasonable doubt?

The Radar Testing Failure

Here's where things went wrong for the prosecution. The Crown conceded — meaning they admitted — that the Justice of the Peace had "misapprehended the evidence." The transcript clearly showed that the officer failed to conduct the "tracking history component" of the manufacturer's testing procedures. This wasn't a minor oversight — it was a fundamental gap in proving the radar device was working properly.

In Canadian law, radar evidence must meet strict reliability standards. The device must be tested according to manufacturer specifications, and this testing must be proven in court. Without the tracking history test, there was no way to establish that the radar readings were accurate. Judge Lenz found that "the accuracy and reliability of the radar device was not proven beyond a reasonable doubt."

What makes this case particularly notable is that the Crown agreed with the defence position. This suggests the testing failure was so obvious and fundamental that the prosecution couldn't reasonably defend it on appeal.

Key Takeaway

Radar evidence is only as good as the testing that backs it up — and incomplete testing can kill an entire speeding case.

For self-represented defendants facing radar-based speeding charges, this case shows the importance of carefully examining whether the officer properly tested the device. Ask to see the testing procedures and compare them to what the manufacturer requires — gaps in testing can be grounds for acquittal.

R v Fink

Ontario Court of Justice 10 May 2004 speeding

R. v. Fink

Ontario Court of Justice proceeding
Ontario Court of Justice — Justice of the Peace A. Puusaari | May 10, 2004, Bradford, Ontario


Background

Terry Fink was charged with speeding under the Highway Traffic Act. The case was scheduled to proceed before Justice of the Peace A. Puusaari in Bradford on May 10, 2004. Fink had legal representation through counsel S. Feeney, while the prosecution was handled by a municipal prosecutor.

What makes this case notable isn't what happened during trial, but what happened before it could even begin. The prosecution made a strategic decision that would end the case before any evidence was heard.

Issues

  1. Whether the prosecution would proceed with the speeding charge against Fink

The Withdrawal

Before any substantive proceedings could begin, prosecutor Feeney addressed the court with a simple but decisive statement: the prosecution was withdrawing the charge against Terry Fink. The Justice of the Peace immediately accepted this withdrawal, thanking the prosecutor and formally dismissing the charge.

While the transcript doesn't reveal the specific reasons for the withdrawal, prosecutorial decisions to withdraw charges typically occur when there are concerns about the strength of evidence, procedural issues, or other factors that make successful prosecution unlikely or inappropriate. The prosecution has the discretion to withdraw charges at any time before a conviction is entered.

Key Takeaway

Charges can be withdrawn by the prosecution at any stage of proceedings, even on the trial date itself.

This case demonstrates that having proper legal representation can sometimes lead to favorable outcomes through pre-trial negotiations or prosecutorial review that results in charges being withdrawn without the need for a contested hearing.

R v Furlong

Unreported

Ontario Court of Justice 2 November 1985 speeding

R. v. Furlong

[Citation not provided]
Ontario Court of Justice — Appeal transcript | 1985


Background

Mr. Furlong was charged with speeding after being clocked at 110 km/h in a 60 km/h zone. A police officer using a moving radar unit testified that he picked up Furlong's vehicle and clocked it at 110 km/h on three separate occasions. The officer stated he was satisfied the vehicle was speeding even visually, and that he tracked it with the radar gun.

At trial, Furlong's defence made a motion for non-suit (essentially arguing the Crown hadn't proven its case). The defence argued there was insufficient evidence about who tested the radar equipment. The Justice of the Peace denied the motion and convicted Furlong, who then appealed.

Issues

  1. Was there sufficient evidence that a qualified operator tested the radar equipment?
  2. Can a court infer who tested the equipment based on circumstantial evidence?

The Fatal Gap in Radar Evidence

The case turned on a critical gap in the officer's testimony. The officer testified that "the machine was tested at 5:39 and 5:56 and was working accurately per the manufacturer's specifications" — but crucially, he never said he tested it. While the officer did testify that he was a qualified radar operator, there was no direct evidence connecting him to the actual testing of the equipment.

The Crown argued that the officer's exact words were "It was tested and I found it to be accurate," but the appeal court judge listened to the tape recording and confirmed that's not what the officer actually said. The Justice of the Peace had ruled that he "knew" the officer was the one who did the testing because there was no one else in the police car — but this inference wasn't supported by evidence, as there was no testimony establishing the officer was alone in the vehicle.

The appeal court found this gap fatal to the prosecution's case. For radar evidence to be admissible, the Crown must prove that a qualified operator tested the equipment and found it working properly. Without clear evidence of who performed the test, this essential element of the case collapsed.

Key Takeaway

In radar cases, the Crown must prove exactly who tested the equipment — assumptions and inferences aren't enough.

This case shows that even seemingly minor gaps in police testimony can be fatal to the Crown's case. If you're facing a radar-based speeding charge, pay careful attention to whether the officer clearly testifies that he or she personally tested the equipment.

R v Giacomelli

Ontario Court of Justice 6 October 2008 speeding

R. v. Giacomelli

[2008] O.J. No. 5701
Ontario Court of Justice — C.P. Mutuma J.P. | October 6, 2008


Background

On New Year's Day 2007 at 11:39 a.m., Fabrizio Giacomelli was allegedly caught speeding on Bay Avenue in Toronto. The officer clocked him doing 87 km/h in a 50 km/h zone using laser equipment — a significant violation of 37 km/h over the limit under section 128 of the Highway Traffic Act.

The officer testified that he was properly trained on the laser device, had tested it before and after use according to manufacturer specifications, and regularly worked that same location. The prosecution seemed to have a solid case with clear evidence of excessive speeding.

Issues

  1. Whether the laser evidence was reliable and properly obtained
  2. Whether inconsistencies in the officer's testimony undermined the Crown's case

The Cross-Examination Strategy

Rather than attacking the reliability of the laser itself, Giacomelli's agent focused on the officer's training process and note-taking practices. During cross-examination, the agent exposed "areas that were rather inconsistent" in the officer's testimony. The court noted problems with information "not included in the notes but provided through the use of the memory by the officer."

Justice Mutuma found the officer credible regarding his general work practices and daily operations of the laser equipment. There was no dispute about the actual speed reading of 87 km/h. However, the inconsistencies that emerged during cross-examination about the officer's notes and memory were significant enough to undermine the prosecution's case entirely.

Key Takeaway

Even rock-solid technical evidence can be defeated if the officer's testimony contains inconsistencies during cross-examination.

This case shows that challenging an officer's note-taking practices and memory can be an effective defence strategy, even when the underlying technical evidence appears strong. Preparation for cross-examination on these procedural details can create reasonable doubt.

R v Grainger

[1958] O.J. No. 218

Ontario Supreme Court - Court of Appeal 15 May 1958 speeding

R. v. Grainger

[1958] O.J. No. 218
Ontario Supreme Court - Court of Appeal — Porter C.J.O., Roach and Gibson JJ.A. | May 15, 1958


Background

On January 13, 1958, Grainger was caught driving 45 mph in a 30 mph zone on King Street West in Toronto at 11:10 a.m. The evidence against him came entirely from a radar speedmeter operated by a police officer. When Grainger appeared in Police Court, his lawyer made a preliminary objection — the Crown should have to qualify the officer as an expert before allowing radar evidence.

The officer admitted he wasn't an electronics expert and couldn't explain the scientific mechanism behind the radar. But he testified that he'd spent two weeks familiarizing himself with the machine, that police technicians maintained it well, that he calibrated it using a tuning fork that morning, and that in his experience the data was "extremely accurate." The magistrate convicted Grainger and fined him $50 (he had previous speeding convictions). Grainger's lawyer applied to state a case, arguing the radar evidence was "incompetent and inadmissible" without proper proof.

Issues

  1. Can radar evidence be admitted without qualifying the operating officer as an expert in electronics?
  2. What foundation must be laid before radar speedmeter readings can be admitted as evidence?

The Radar Evidence Foundation

The Court of Appeal upheld the conviction, establishing that you don't need an electronics expert to operate radar — just someone who knows how to use it properly. Justice Roach found that the officer's evidence implicitly established three key things: (1) the radar machine was capable of accurately measuring vehicle speeds when properly used, (2) it was in good working condition at the time, and (3) it was being properly operated.

The court emphasized that while the officer couldn't give a scientific explanation of radar technology, he was familiar with proper operation procedures, had two weeks of training, and calibrated the device that morning with a tuning fork. His testimony that the machine was "extremely accurate" based on his experience was sufficient foundation. The court noted that if the defence believed the radar was unreliable, they could have called their own evidence to challenge it — but Grainger didn't.

This became a foundational case establishing that radar evidence doesn't require expert scientific testimony about electromagnetic waves and Doppler shift principles — just testimony from a trained operator about proper use, calibration, and accuracy based on experience.

Key Takeaway

Radar evidence can be admitted through a trained operator's testimony alone, without requiring an electronics expert.

If you're challenging radar evidence, focus on questioning the officer's training, calibration procedures, and maintenance records rather than demanding scientific expertise. The burden is on you to present evidence that the specific radar unit was malfunctioning or improperly used.

R v Grewal

Unreported

Ontario Court of Justice 17 April 2002 speeding

R. v. Grewal

Ontario Court of Justice — Justice D. McAleer
June 28th, 2001 | Eastbound Lakeshore Boulevard West, Toronto


Background

Manraj Grewal was charged with speeding 94 kilometres per hour in a 60 kilometre per hour zone on the Highway Traffic Act. The officer issued the ticket on June 25th, 2000, at 12:31 P.M. on Lakeshore Boulevard West in Toronto. But there was a problem — the prosecution realized there was an issue with the original ticket and decided to "fix" it by having someone make changes to the document before filing it with the court.

When the case came to trial, Grewal's agent, Mr. Pereti, appeared ready to defend. The Crown was seeking a conviction and the standard penalty, but they had to deal with the fact that their key evidence — the ticket itself — had been altered after it was originally issued.

Issues

  1. Can the prosecution modify a Provincial Offences Act ticket after it has been issued but before filing it with the court?
  2. Does altering the original ticket invalidate the entire prosecution?

The Altered Evidence Problem

The court found that the Crown had made changes to the original ticket after it was issued. Justice McAleer was clear about what this meant: the prosecution cannot modify original documents and then present them as authentic evidence. The judge noted that this type of alteration compromises the integrity of the evidence and violates basic principles of fairness in the justice system.

Under the Provincial Offences Act, the original ticket serves as the foundation for the entire prosecution. When that document is altered — even if the changes seem minor or "corrective" — it becomes unreliable evidence. The court emphasized that the prosecution must work with the evidence as it originally existed, not as they wish it had been created.

Justice McAleer ruled that allowing altered tickets to proceed would set a dangerous precedent. If prosecutions could modify their evidence after the fact, it would undermine public confidence in the justice system and create unfair advantages for the Crown.

Key Takeaway

Original evidence must remain untouched — any alterations by the prosecution can kill their entire case.

If you notice that the prosecution's ticket or certificate has been modified, altered, or "corrected" after it was originally issued, challenge it immediately. The court takes evidence integrity seriously, and this type of procedural error can result in a complete dismissal.

John Guglietti was charged with speeding 138 km/h in a 100 km/h zone on Highway 407 in Milton on March 1, 2003. Officer Ian Michel of the OPP Port Credit Detachment testified that he clocked Guglietti's speed using a handheld Genesis VP Radar unit. Michel said he had been with the OPP since April 2001 and testified that he was "trained as a radar operator" both at the OPP Academy in Orillia and at the detachment level.

Guglietti's agent, Mr. Alesandro, made a motion for non-suit, arguing that the officer never said he was *qualified* to operate the specific radar unit — only that he was trained. Justice of the Peace Bonas denied the motion, calling the distinction between "trained" and "qualified" mere "semantics" and finding the words "interchangeable to some extent." Guglietti was convicted and appealed.

Issues

  1. Was there sufficient evidence that Officer Michel was qualified to operate the specific Genesis VP radar unit?
  2. Can the words "trained" and "qualified" be used interchangeably when it comes to radar operation?

The Training vs. Qualification Distinction

Justice Forsyth found that the Justice of the Peace made a fundamental error. The evidence showed only that Officer Michel had received generic radar training — not training on the specific Genesis VP unit he used. More importantly, there was no evidence whatsoever that he was *qualified* to operate any radar unit, let alone this particular model.

The court referenced R. v. He, where Justice Bellefontaine established that "there must be evidence to establish beyond a reasonable doubt that the officer was trained and qualified in the operation of the machine." Training and qualification are distinct concepts: a person can receive training and still fail a qualification test, or cease training before becoming qualified.

Justice Forsyth rejected the Justice of the Peace's finding that these terms were interchangeable, noting that even dictionary definitions show qualification requires "knowledge, training *and experience*." The court found there was "no factual foundation" for concluding that Officer Michel was qualified on this specific radar unit.

Key Takeaway

The Crown must prove the officer was both trained AND qualified on the specific radar unit used — generic radar training isn't enough.

If you're challenging radar evidence, press the officer on their specific qualifications for the exact model of radar used in your case. Training alone doesn't establish competence to operate specialized equipment.

R v Hall

Unreported (Ont. Prov. Ct., August 5, 1987)

Provincial Court (Criminal Division), Hamilton 7 February 2013 constitutional challenge

R. v. Hall

Provincial Court (Criminal Division), Hamilton
Provincial Court Judge Norman Bennett | August 5, 1987


Background

Frederick Hall was convicted of a speeding offence under the Provincial Offences Act and appealed to Judge Bennett. The case centered on radar evidence presented at the original trial. The officer who issued the ticket testified that the radar device had been checked "according to the manufacturer's standards" and was "operating accurately," but failed to provide crucial details about how and when the testing was actually performed.

Judge Bennett had apparently seen similar problems with radar evidence in previous cases, noting that he had "recently had a similar argument presented" and had "granted the appeal" in that earlier matter due to insufficient foundation for the electronic evidence.

Issues

  1. What minimum evidentiary foundation must be established before a court can accept radar evidence?
  2. Did the officer's testimony meet the required standard for admitting electronic equipment evidence?

The Radar Evidence Foundation Requirements

Judge Bennett established a clear five-part minimum test that officers must satisfy when presenting radar evidence. The officer must testify about: (a) the time that he actually tested the equipment; (b) when he went on duty; (c) how he tested the equipment, including whether he used a tuning fork; (d) that after finishing his shift or before leaving his radar post, he re-tested the equipment to ensure it was still functioning properly; and (e) his qualifications as a radar technician.

The judge emphasized this should be "simple procedure" — an officer should say something like "At 9 a.m. I tested the Unigrip radar device by the following method and I tested it according to the manufacturer's specific instructions" and then explain exactly how the testing was done. The officer should also "indicate that he was a qualified radar technician and set out what his qualifications are."

In this case, the officer had stated only that "the radar had been checked prior, according to the manufacturer's standards, and proved to be operating accurately." Critically, "The officer did not say that he tested it or when it was tested." This vague testimony fell far short of the required foundation.

Key Takeaway

Radar evidence requires specific, detailed testimony about testing procedures — generic statements about manufacturer standards aren't enough.

If you're facing a radar-based speeding ticket, examine whether the officer provided detailed testimony about pre-shift testing, post-shift testing, testing methods, timing, and qualifications. Vague assurances about following "standards" may not meet the legal threshold for admitting electronic evidence.

R v Hawkins

2009 ONCJ 101

Ontario Court of Justice 6 January 2009 speeding

R. v. Hawkins

2009 ONCJ 101
Ontario Court of Justice — Justice of the Peace M.A. Cuthbertson | January 6, 2009


Background

On January 13, 2008, OPP Officer S. Vallier was running radar enforcement on Wellington Road 109 in Mapleton Township using a Genesis VP radar device. He clocked Russell Hawkins driving eastbound at 109 km/h in an 80 km/h zone. The officer testified he was qualified to operate the radar unit and had tested it before and after the traffic stop according to manufacturer specifications. Hawkins was the only vehicle in sight when the radar locked three identical readings of 109 km/h.

At trial, the defence didn't call any evidence but challenged whether Officer Vallier had properly followed all manufacturer requirements when operating the radar device. This led to a deep dive into something called "tracking history" — a procedure the officer admitted he'd never heard of.

Issues

  1. What testing requirements must be met for radar evidence in speeding cases?
  2. Did Officer Vallier properly conduct the manufacturer-required "tracking history" procedure?

The Tracking History Requirement

The court examined page 30 of the Genesis-VP User's Manual, which outlined a mandatory "tracking history" procedure. This required four steps: (1) visual observation and speed estimation of the target vehicle, (2) placing the radar in operational mode, (3) confirming the radar display is consistent with visual observations and that the audio tracking tone matches the visual observations, and (4) taking no enforcement action if any component is missing.

Officer Vallier initially testified he'd never heard of "tracking history." When pressed, he admitted he might have read about it but didn't really understand it. Most damaging: he never testified about hearing an audio tone during the traffic stop, and his notes contained no mention of it. Only during re-examination — after being walked through the manual — did he suddenly "recall" hearing a tone and estimating the vehicle's speed at 110 km/h.

The court found this late testimony unreliable, noting it "rang more of wishful thinking than of certainty." The officer also failed to testify whether the radar's audio was even turned on or at what volume level. Justice Cuthbertson concluded that an officer operating radar equipment must follow all manufacturer requirements, including tracking history, not just the basic before-and-after testing established in R. v. Bigioni and R. v. Vancrey.

Key Takeaway

Radar evidence requires more than just pre- and post-operation testing — officers must follow every manufacturer requirement, including tracking history procedures.

If you're facing a radar-based speeding charge, obtain the manufacturer's manual for the specific device used and scrutinize whether the officer followed all operational requirements, not just the basic testing protocols most lawyers know about.

R v He

[2003] O.J. No. 2257

Ontario Court of Appeal 26 May 2003 speeding

R. v. He

[2003] O.J. No. 2257
Ontario Court of Appeal — Armstrong J.A. (In Chambers) | May 26, 2003


Background

Li He was pulled over by Ontario Provincial Police Officer John Ritchie and charged with speeding under section 128 of the Highway Traffic Act. The officer testified that he clocked He travelling at 122 kilometres per hour in an 80 km/h zone using a Genesis II radar gun. Justice of the Peace B. Brown convicted He on June 20, 2002, finding him guilty of travelling 114 km/h in the 80 km/h zone (interestingly, a lower speed than what the officer originally testified to).

He wasn't satisfied with this result and appealed his conviction to the Ontario Court of Justice, where Justice Bellefontaine heard his case. When that appeal was dismissed, He sought leave (permission) to appeal to the Ontario Court of Appeal — the highest level of appeal available for Provincial Offences Act matters.

Issues

  1. Was Officer Ritchie qualified to operate the Genesis II radar gun?
  2. Did Justice Bellefontaine make an error of law in upholding the conviction?

The Radar Qualification Challenge

He's defence strategy focused entirely on attacking Officer Ritchie's qualifications to operate the specific radar device — a Genesis II. This is a common defence tactic in speeding cases because the Crown must prove that the officer operating the radar device was properly trained and qualified to use that specific model.

The justice of the peace was satisfied that Officer Ritchie was qualified to operate the Genesis II radar gun. On appeal, Justice Bellefontaine found there was a factual foundation for this conclusion, stating: "In my view there was factual foundation upon which it was open to her worship to find as she did specifically factually find that the officer was trained and qualified officer... I'm satisfied that there was a factual basis for her to find that he was in fact a trained and qualified operator."

At the Court of Appeal level, Armstrong J.A. applied section 139 of the Provincial Offences Act, which requires an error of law for leave to appeal to be granted. The court found no legal error in how Justice Bellefontaine handled the qualification issue.

Key Takeaway

Challenging an officer's radar qualifications requires more than just asking the question — you need evidence that the officer wasn't properly trained.

While questioning radar operator qualifications is a legitimate defence strategy, courts will generally defer to trial judges' findings of fact about officer qualifications unless there's a clear legal error in how the evidence was evaluated.

R v Hofland

2011 ONCJ 40

Ontario Court of Justice 26 January 2011 speeding

R. v. Hofland

2011 ONCJ 40
Ontario Court of Justice — Justice of the Peace Kenneth W. Dechert | January 26, 2011


Background

On February 12, 2010, Police Constable Kevin Hanowski was conducting speed enforcement at the intersection of Trafalgar Road and Hornby Road in Halton Hills. Using a hand-held LTI 20/20 laser device, he clocked Andrew Hofland's silver Volkswagen doing 107 km/h in a posted 70 km/h zone as the vehicle travelled northbound through an S-bend on Trafalgar Road. Hofland was charged under section 128 of the Highway Traffic Act and pleaded not guilty.

At trial, Constable Hanowski testified that he had tested the laser device both before and after his shift "according to manufacturer's instructions." He described performing a display test, sight alignment test, and fixed zero velocity distance test. However, under cross-examination by defence counsel, cracks began to appear in his testimony about the testing procedures.

Issues

  1. Whether the prosecution proved all elements of the speeding offence beyond a reasonable doubt
  2. Whether the laser speed reading was reliable given questions about proper testing procedures

The Laser Testing Controversy

The case turned on whether Constable Hanowski had properly tested the laser device. During cross-examination, defence counsel produced the actual "Laser Technology LTI 20/20 True Speed Metric Users Manual" and walked the officer through its requirements. The manual prescribed a specific "Instrument Self Test" procedure that required the operator to actively initiate and complete certain steps.

Hanowski admitted he had never performed this self-test. When asked about it, he initially claimed "the unit does its own self test" and would display problems on the LED screen. But when confronted with the manual's specific instructions, he acknowledged he wasn't following the manufacturer's prescribed self-test procedure at all. The officer also admitted he was doing distance tests at 40 and 50 metres instead of the recommended single test at 60 metres, and was following his instructor's directions rather than the actual manual.

The Justice of the Peace found this non-compliance fatal to the prosecution's case. Citing R. v. Niewiadomski and R. v. Kololgi, he ruled that "only with strict compliance to the manufacturer's mandatory specifications can the Court be assured of the reliability and the accuracy of reading obtained through operation of the device beyond a reasonable doubt."

Key Takeaway

Police officers must follow the manufacturer's actual testing procedures for speed measurement devices, not just what they were taught in training.

This case shows the importance of demanding specifics about device testing during cross-examination. If the officer claims to follow "manufacturer's instructions," ask them to identify exactly which tests they performed and compare that to the actual manual if possible.

R v Hough

[1996] O.J. No. 5456

Ontario Court of Justice (Provincial Division) 5 January 1996 speeding

R. v. Hough

[1996] O.J. No. 5456
Ontario Court of Justice (Provincial Division) — Gonet Prov. J. | January 5, 1996


Background

Rodney Hough was charged with speeding under section 128 of the Highway Traffic Act. After being convicted at trial, Hough appealed to the Ontario Court of Justice (Provincial Division) in Guelph. His appeal raised two issues: first, that the Crown had failed to provide full disclosure in breach of his Charter rights, and second, that the Crown had failed to prove the speeding charge beyond a reasonable doubt due to problems with the radar evidence.

The case centered on the qualifications of the police officer who operated the radar device that allegedly caught Hough speeding. The officer's training consisted of informal sessions with other OPP officers — sometimes lasting just a couple of hours, other times about half a day, depending on who was doing the training.

Issues

  1. Did the Crown fail to provide full disclosure in breach of the Charter?
  2. Did the Crown prove beyond a reasonable doubt that the radar evidence was reliable, particularly regarding the officer's qualifications to operate the device?

The Radar Evidence Problem

Judge Gonet quickly dismissed the Charter disclosure argument, finding that full disclosure had been provided. However, the radar evidence presented a much bigger problem for the prosecution.

The officer who operated the radar had received only informal, inconsistent training from other OPP officers. More critically, he had absolutely no knowledge of the manufacturer's instructions for proper use of the radar device. He hadn't read any materials about how to use the instrument, how to check it, or how to set it up using tuning forks. Without access to the manufacturer's specifications, he couldn't satisfy the court that the radar setup was proper or that it had been completed according to the manufacturer's directions.

Judge Gonet followed the reasoning from R. v. Christopher Brewer [1988] O.J. No. 2531, where Judge Lampkin had faced nearly identical facts involving inadequate radar operator training. The court found that the Crown had failed to establish a prima facie case — meaning they hadn't even met the basic threshold of proving their case before the defence needed to respond.

Key Takeaway

Radar evidence requires more than just an officer with informal training — the Crown must prove the operator was qualified according to manufacturer specifications.

If you're facing a radar-based speeding charge, demand disclosure about the officer's training and qualifications. The Crown must prove the officer knew how to properly set up, calibrate, and operate the specific radar device according to the manufacturer's instructions — not just that another cop showed them the basics.

R v Kleiner

[2008] ONCJ 159

Ontario Court of Justice 13 March 2008 speeding

R. v. Kleiner

2008 ONCJ 159
Ontario Court of Justice — Lampkin J. | March 13, 2008


Background

On October 27, 2005, Luisa Kleiner was driving eastbound on Brookside Road in Richmond Hill when Constable Steven Marsh clocked her at 83 km/h in a 40 km/h zone using a hand-held Muni-Quip Tribar radar device. Marsh was positioned on Chantilly Crescent with a clear view of traffic, and he testified that Kleiner's vehicle was the only one in the radar beam when he activated the device. He had tested the radar twice that day according to manufacturer's instructions, and it functioned properly both times.

Kleiner applied for trial and was convicted by Justice of the Peace L. Wichman, who fined her $258. She appealed, arguing that the officer wasn't properly qualified to operate the radar device he used, that the Justice of the Peace relied on inconclusive evidence, and that he failed to give adequate reasons for preferring the officer's testimony over hers.

Issues

  1. Was Constable Marsh qualified to operate the Muni-Quip Tribar radar device?
  2. Did the Justice of the Peace err by relying on insufficient evidence?
  3. Were the reasons for judgment adequate?

The Equipment Change Challenge

Kleiner's defence focused on a key fact that emerged in cross-examination: Marsh had been trained on radar in 1989 and certified as an instructor in 2002, but by the time of the offence in 2005, his police service had switched to a different radar model over a two-year period. When asked directly, Marsh admitted that "the equipment that you were trained on in 1989 and certified as an instructor in 2002 is no longer the equipment that now is being used."

However, Judge Lampkin found this argument missed the mark. The evidence showed the changeover was gradual — on the day in question, Marsh was still using the Muni-Quip Tribar he was trained on, not the newer equipment. The court distinguished this from R. v. Brewer, where an officer couldn't confirm he followed manufacturer specifications and admitted reading "absolutely nothing" from the manufacturer about proper operation.

Following the leading Ontario case R. v. Grainger, the court found that formal certification isn't required — what matters is that the operator is qualified, the device was tested before and after use, and it functioned properly. Unlike the Quebec approach in D'Astous v. Baie-Comeau, Ontario doesn't require passing an exam or proving tuning fork accuracy.

The Credibility Battle

Kleiner testified she had turned left from Shaftsbury Road onto Brookside just 37 metres before the officer's position — 14 metres on flat ground, then 23 metres downhill. She argued it was impossible to reach 83 km/h in such a short distance. However, the Justice of the Peace rejected this evidence, noting that Marsh knew the area well (he set up there frequently due to complaints) and estimated she was 100-200 metres away when first observed, not 37 metres.

On appeal, Judge Lampkin found the Justice of the Peace's reasoning adequate under R. v. Sheppard and R. v. W.(D.). The trial judge clearly preferred the officer's evidence about distances and rejected Kleiner's version of events. While the reasons were brief, they left no doubt why the prosecution succeeded.

Key Takeaway

Equipment changes don't automatically disqualify a radar operator — what matters is whether they were qualified to use the specific device on the day of the offence.

If you're challenging radar evidence, focus on whether the officer was properly trained on the actual device used, whether it was tested according to manufacturer instructions, and whether there's evidence it malfunctioned. Simply showing that police services have upgraded their equipment won't invalidate a reading from older, properly-operated equipment.

R v Kololgi

[2009] O.J. No. 5742

Ontario Court of Justice 14 December 2009 stunt driving

R. v. Kololgi

[2009] O.J. No. 5742
Ontario Court of Justice — Justice A. Hourigan | December 14, 2009


Background

On January 12, 2009, Constable Roman Santos was operating radar when he spotted Shilpa Kololgi driving what he considered to be a high rate of speed. Using his mobile radar unit, he clocked her at 106 kilometres per hour in a posted 60 km/h zone — a whopping 46 km/h over the limit. Under Ontario's stunt driving laws, anything over 49 km/h above the posted limit triggers the serious charge under section 172(1) of the Highway Traffic Act.

Kololgi was convicted at trial by a Justice of the Peace, but she appealed to the Ontario Court of Justice. Her defence was simple: the officer hadn't followed the manufacturer's instructions for operating the radar device, so the speed reading shouldn't be trusted. She testified that she was confident she wasn't going more than 50 km/h and kept her eye on the speedometer, though she couldn't recall her exact speed.

Issues

  1. Did the officer's failure to follow the manufacturer's radar operating instructions create reasonable doubt about the accuracy of the speed reading?
  2. Should police be required to strictly comply with manufacturer directions before using radar evidence for enforcement?

The Radar Manual Requirements

The case turned on Section 9.1 of the Genesis 2 Radar Device manual, which requires officers to compile a "tracking history" for each enforcement action. This includes making a visual estimate of the vehicle's speed and correlating the patrol speed of the police vehicle with the speed displayed on the radar unit. If any of these components aren't completed, the manual says "no enforcement action shall be undertaken."

Constable Santos admitted he did neither: he made no speed estimate beyond observing Kololgi was going "at a high rate of speed," and he never correlated his patrol car's actual speed with what the radar was showing. While he tested the device at the beginning and end of his shift (which showed it was working), he ignored these operational requirements during the actual traffic stop.

Justice Hourigan rejected the Crown's argument that police can follow their own policies instead of manufacturer directions. He relied on several recent cases, including R. v. Cormier and R. v. Niewiadomski, which held that "there could be no reason for the device manufacture to set out specifications and directions if it mattered not whether they were complied with." The judge emphasized that stunt driving is one of the most serious charges under the Highway Traffic Act, with severe consequences, so the evidence must be rock-solid.

Key Takeaway

Police officers must follow manufacturer instructions when operating radar devices, or the speed reading becomes unreliable evidence.

If you're facing a radar-based speeding or stunt driving charge, demand disclosure of the radar manual and the officer's notes to see if proper procedures were followed. Even small procedural shortcuts can create the reasonable doubt needed for an acquittal.

R v Koumoudouros

[2005] O.J. No. 5055

Ontario Court of Justice 17 May 2005 speeding

R. v. Koumoudouros

[2005] O.J. No. 5055
Ontario Court of Justice — B. Zabel J. | May 17, 2005


Background

Branita Koumoudouros was charged with speeding under the Highway Traffic Act. The police officer used the speedometer in his own patrol vehicle to pace her speed — a method where the officer follows behind and matches the defendant's speed using his cruiser's speedometer as the measuring device. At trial, the officer testified that his speedometer was "certified and calibrated" but couldn't provide any details about who did the certification, when it was done, or any documentation proving it.

The defence lawyer, represented by agent Frank Alfano, cross-examined the officer extensively on this point. The officer admitted he didn't know who certified the speedometer, couldn't say when it was calibrated, didn't know how old the vehicle was, and had no certificate or documentation — just that he was "told it's a certified calibrated speedometer" and had "no reason to doubt that information." Despite this cross-examination revealing these gaps, the justice of the peace convicted Koumoudouros, stating she had "no reason to doubt" the officer's belief that the speedometer was working properly.

Issues

  1. Whether the officer's unsupported testimony that the speedometer was "certified and calibrated" was sufficient proof beyond a reasonable doubt
  2. Whether the justice of the peace erred in law by ignoring the reasonable doubt established through cross-examination

The Speedometer Certification Problem

This case hinges on a fundamental evidentiary principle: the prosecution must prove every element of their case beyond a reasonable doubt. When police use speedometers for pacing, they need to establish that the device is accurate. The Crown argued that speedometers are presumed accurate unless there's evidence to the contrary, relying on cases like Bland.

However, Justice Zabel found this case distinguishable from Bland. In Bland, there was actually a certificate showing the speedometer had been tested against radar equipment, with documentation of when it was done and how many kilometres the vehicle had travelled since calibration. Here, there was literally nothing — no certificate, no testing records, no knowledge of when any calibration might have occurred.

The court emphasized that once the defence cross-examined the officer and exposed these fundamental gaps in his knowledge, a reasonable doubt was established. The officer couldn't answer basic questions: Who certified it? When? Where's the certificate? How long ago? The justice of the peace erred in law by simply accepting the officer's bare assertion and ignoring the doubt created by cross-examination.

Key Takeaway

Effective cross-examination can expose fatal weaknesses in seemingly routine police evidence.

When facing speedometer pacing cases, defendants should probe the officer's knowledge about calibration and certification. If the officer can't provide specifics about when, how, or by whom the speedometer was certified, this may establish reasonable doubt about the accuracy of the speed measurement, even without calling defence evidence.

R v Le

[2002] O.J. No. 894

Ontario Court of Justice - Provincial Offences Appeal Court 4 March 2002 speeding

R. v. Le

[2002] O.J. No. 894
Ontario Court of Justice, Provincial Offences Appeal Court — Fairgrieve J. | March 4, 2002


Background

Huu-Hat Le was caught speeding on Islington Avenue in Toronto — 74 km/h in a 50 km/h zone. Constable D'Agostino of Toronto Police Services used a Laser Tech Marksman 2020 speed measuring device, pointing the red dot on the front of Le's vehicle and getting the reading. The officer testified he was a qualified laser operator, had tested the device before and after use, and found it in proper working order according to manufacturer specifications.

Le's defence lawyer didn't cross-examine the officer or call any evidence. The Justice of the Peace convicted Le, simply stating he was "satisfied that the laser was accurate." Le appealed, arguing the prosecution hadn't proven the laser device was reliable.

Issues

  1. What evidence is required to prove a laser speed measuring device is accurate and reliable?
  2. Can courts now take judicial notice of laser technology's reliability without requiring independent verification?

The Evolution of Laser Evidence

This case came down to interpreting R. v. Vancrey, where the Ontario Court of Appeal had upheld a laser conviction based on evidence that included comparison with an accurate radar unit. Le's lawyer argued Vancrey required such independent testing. But Justice Fairgrieve disagreed, finding that Vancrey didn't establish a mandatory requirement — it just said that particular evidence was sufficient.

The key breakthrough came from Quebec's City of Joliette v. Delangis, where the Court of Appeal ruled that courts could take judicial notice of laser technology's reliability. As the Quebec court put it: why require proof of laser technology when we don't require proof of how odometers or modern thermometers work? Justice Fairgrieve also relied on R. v. Mukasa, where Justice Pockele noted that laser technology "had eight years of history in this country" and was "no longer new and novel."

The court found that laser speed detection devices had been used by law enforcement for almost a decade, evidence from them was routinely admitted as reliable, and the technology was now so well-established that judicial notice could be taken of its accuracy — similar to how courts handle radar evidence.

Key Takeaway

You can't beat a laser speeding ticket just by arguing the prosecution didn't prove the technology works.

Courts now accept laser speed detection as reliable technology that doesn't require independent verification. Your defence needs to focus on whether the specific device was working properly, whether the officer was trained and competent, or whether the officer made errors in operation — not on challenging the underlying technology itself.

R v Marshall

[1995] O.J. No. 4476

Ontario Court of Justice (Provincial Division) 22 December 1995 speeding

R. v. Marshall

[1995] O.J. No. 4476
Ontario Court of Justice (Provincial Division) — Weagant Prov. J. | December 22, 1995


Background

Kyle Marshall was charged with speeding under the Highway Traffic Act, allegedly driving 99 kilometres per hour. The Crown's case relied entirely on a speed reading from a laser speed detection device — a relatively new technology at the time. The officer who operated the laser testified that she was qualified to use it and had performed various tests to ensure it was working properly. One of those tests involved checking the laser's accuracy against a traditional radar machine.

However, the Crown failed to establish that the officer was qualified to operate the radar machine she used to test the laser device. This seemingly minor oversight would prove fatal to their case.

Issues

  1. Whether the Crown proved beyond a reasonable doubt that Marshall was driving 99 km/h
  2. Whether proper foundation was laid for the laser speed detection evidence

The Chain of Evidence Problem

Judge Weagant identified a critical flaw in the Crown's evidence. While the officer was qualified to operate the laser device, she tested it against a radar machine — and the Crown provided no evidence that she was qualified to operate that radar machine. The judge noted that "perhaps only because of the state of the jurisprudence at this point, the Crown did not see fit to ask the questions" that would have established the officer's radar qualifications.

This created a logical problem: if testing against the radar was "the all-important test" for determining that the laser was capable of measuring vehicle speed, then the Crown needed to prove the radar was working properly and that the officer could operate it correctly. Without that foundation, the entire chain of evidence collapsed. The judge emphasized that proper evidence would need to be called to establish "beyond a reasonable doubt that the radar was in working order and that the police officer using it for test purposes is qualified to so do."

The judge also noted that while the officer's visual observations could have supported a speeding conviction, no speed estimate was provided — the guilty verdict had been based entirely on the laser readings.

Key Takeaway

Even sophisticated technology is only as reliable as the foundation evidence supporting it.

This case demonstrates that the Crown must establish a complete chain of evidence for speed detection devices. When challenging radar or laser evidence, defendants should examine whether proper foundation was laid for all equipment used, including any devices used to test or calibrate the primary speed detection equipment.

R v Mateus

Unreported

Ontario Court of Justice 8 September 2008 speeding

R. v. Mateus

[2008] O.J. No. 5590
Ontario Court of Justice — D. Robinson J.P. | September 8, 2008


Background

Marco Mateus was charged under section 128 of the Highway Traffic Act for speeding. The officer was stationed on Weston Road specifically to monitor the speed of moving motor vehicles using radar equipment. During the trial, the officer testified that he had tested the equipment and found it to be in proper working order before using it to clock Mateus's speed.

However, the defence challenged the reliability of the radar evidence by arguing that the officer's testing procedures were flawed. The case turned entirely on whether the officer had properly tested the radar equipment according to the manufacturer's specifications.

Issues

  1. Were the officer's testing procedures for the radar equipment adequate to establish its reliability?
  2. Can the court rely on radar evidence when the testing procedures don't fully comply with manufacturer specifications?

The Equipment Testing Defect

Justice Robinson found that despite the officer's testimony about testing the equipment, there were "inconsistencies and the seemingly non-full compliance with the tests outlined by the manufacturer." The court emphasized that unless radar testing procedures are "consistent and compliant with that of the tests set out by the manufacturer," the evidence is flawed and unreliable.

The judge applied established case law holding that when test procedures are flawed, "one cannot rely on the reading of the machine." This wasn't about whether the radar gun actually worked — it was about whether the Crown could prove it worked through proper testing protocols. The court noted there was a "compelling argument" that the testing failures created reasonable doubt about the equipment's reliability.

Key Takeaway

Radar evidence is only as good as the testing procedures used to verify the equipment's accuracy.

Self-represented defendants should scrutinize whether the officer followed the manufacturer's specific testing protocols exactly. Even if the equipment appeared to work properly, deviations from required testing procedures can create reasonable doubt and lead to dismissal of speeding charges.

Background

Sharon Meyer was charged with speeding after being clocked at 77 kilometres per hour in a 60 km/h zone. The case came down to a technical battle over radar evidence — specifically, whether the Crown had properly proven that the radar device was operating accurately and that the officer was qualified to use it.

At trial, Crown counsel Mr. H. Dales presented what seemed like a straightforward speeding case. Defence counsel Mr. F. Streiman, however, wasn't buying it. The transcript reveals a detailed examination of the radar evidence that would ultimately expose fatal gaps in the Crown's case.

Issues

  1. Did the Crown prove that the radar device was operating properly and accurately?
  2. Did the Crown prove that the officer was qualified to operate the radar equipment?

The Radar Evidence Problem

The court found that while the officer testified about using the radar device, the Crown failed to establish two crucial elements. First, they didn't prove the device was working accurately at the time of the alleged offence. The officer mentioned that radar devices "must be" calibrated and tested, but provided no evidence that this particular device had actually been properly calibrated or tested.

Second, and more critically, the Crown presented no evidence about the officer's training or qualifications to operate radar equipment. The court noted that radar is a "technical device" that requires specific knowledge to operate properly. An officer can't just pick up a radar gun and start using it — they need to understand how it works, how to test it, and how to ensure accurate readings.

The judge emphasized that "before a radar device can be used to give evidence of the operation of a motor vehicle, it must be proved that the radar device was operating properly and was capable of accurately registering speeds, and that the instrument was operated by someone who had sufficient knowledge of the workings of the instrument."

Key Takeaway

Technical evidence requires technical proof — the Crown can't just assume you'll accept that complex equipment works properly.

If you're fighting a radar-based speeding ticket, demand that the Crown prove both that the device was properly calibrated and tested, and that the officer was actually trained and qualified to use it. These aren't minor technicalities — they're fundamental requirements for reliable evidence.

R v Milelli

Unreported

Provincial Offences Court 28 December 1988 speeding

Her Majesty The Queen v. Fernando Milelli

Provincial Offences Court, Brampton
His Honour Judge R.T. Weseloh | December 28, 1988


Background

Fernando Milelli was charged with speeding after being clocked by radar. During cross-examination, the officer admitted he was not a qualified radar technician and could not repair the machine. More damning, he testified that he did not perform the tests required by the manufacturer's instructions because he wasn't qualified to do them. The officer stated he simply wasn't an "expert" and couldn't follow the technical procedures spelled out in the Muni-Quip MDR 1 Track Radar Operating Instructions manual.

The prosecution argued that an officer doesn't need to be qualified as a technician — that an operator can use radar equipment without being able to repair it or perform all the technical tests. They asked the court to accept the radar evidence despite these admissions.

Issues

  1. Can radar evidence be admitted when the officer admits he's not qualified to perform the manufacturer's required tests?
  2. What level of technical competence must a radar operator demonstrate before their evidence becomes admissible?

The Qualification Requirement

Judge Weseloh was unimpressed with the officer's admissions. The court found that the officer had failed to establish the basic foundation required for radar evidence. The judge noted that the officer "simply cannot be qualified" because he admitted he wasn't capable of following the manufacturer's specifications and couldn't perform the required tests.

The court distinguished between being an "operator" and being qualified to give evidence about radar readings. While an officer doesn't need to be able to repair the equipment, they must be able to demonstrate they can properly operate it according to the manufacturer's instructions and perform the accuracy checks required. The officer's own testimony showed he fell short of this standard.

Most importantly, the court emphasized that the officer "should be guided by all the manufacturer's instructions" and must be able to follow the proper procedures. When an officer admits they can't do the fundamental things the manual requires, their evidence lacks the necessary foundation.

Key Takeaway

An officer who admits they can't perform the manufacturer's required tests has destroyed the foundation for their radar evidence.

If you're facing a radar charge, ask detailed questions about the officer's qualifications and whether they actually performed all the tests specified in the equipment manual. Their own admissions of incompetence can be your best defence.

R v Mohammadi

[2010] O.J. No. 2977

Ontario Court of Justice 12 April 2010 speeding

R. v. Mohammadi

[2010] O.J. No. 2977
Ontario Court of Justice — J.D.G. Waugh J. | April 12, 2010


Background

Abdul Mohammadi was charged with a speeding offence, presumably under the Highway Traffic Act. The case reached the Ontario Court of Justice in Brockville as a Crown appeal — meaning Mohammadi had been acquitted at trial, and the Crown was trying to overturn that acquittal. The Crown's case relied on radar evidence to prove Mohammadi's speed.

The original trial judge had acquitted Mohammadi, and now Justice Waugh was hearing the Crown's appeal of that acquittal. The Crown was arguing that the radar evidence should have been sufficient to secure a conviction.

Issues

  1. Was the radar evidence properly authenticated according to the required procedures?
  2. Should the Crown's appeal of the acquittal be allowed?

The Radar Testing Problem

Justice Waugh's decision hinged on a crucial procedural requirement for radar evidence. The judge explicitly referenced police manuals that require officers to first estimate the speed of a vehicle visually, then check that estimate against the radar reading to ensure the equipment is working properly. This visual estimate must be "within the parameters" of what the radar shows.

The Crown's evidence apparently consisted of the officer simply stating that Mohammadi "was going well over the speed limit" and arguing that this proved the radar was working correctly. Justice Waugh firmly rejected this approach, finding it insufficient to establish that the radar equipment had been properly tested according to the required procedures.

This case demonstrates that radar evidence isn't automatically admissible just because it shows speeding. The Crown must prove that the officer followed proper testing procedures, including making a visual speed estimate before consulting the radar device.

Key Takeaway

Saying someone was "going well over the speed limit" doesn't prove radar equipment was properly tested.

When defending against radar-based speeding charges, challenge whether the officer followed proper testing procedures, including making a visual speed estimate before checking the radar reading.

R v Mukasa

[2001] O.J. No. 262

Ontario Court of Justice 16 November 2000 speeding

R. v. Mukasa; R. v. Spinosa; R. v. O'Brien

[2001] O.J. No. 262
Ontario Court of Justice — Pockele J. | November 16, 2000


Background

Three drivers — Kayemba Mukasa, Maximillian Spinosa, and Martin O'Brien — were all charged with speeding under section 128 of the Highway Traffic Act. All three cases hinged on the same question: whether laser speed detection devices (LSDDs) required special comparative testing against radar devices to be admissible as evidence. Mukasa and Spinosa had been acquitted at trial because justices of the peace ruled the laser evidence inadmissible without proper testing. O'Brien had been convicted and was appealing. The Crown wanted the acquittals overturned, while O'Brien wanted his conviction quashed.

The cases all turned on earlier court decisions that had required police to test laser devices against established radar technology every 30 days to prove accuracy. This comparative testing requirement had become a significant burden for police forces and a common defence strategy for traffic tickets.

Issues

  1. Is laser speed detection technology still "new or novel" technology requiring special verification?
  2. If comparative testing is required, how frequently must it occur and is a 30-day schedule scientifically justified?

The Death of "New Technology"

Justice Pockele delivered a sweeping judgment that fundamentally changed how Ontario courts treat laser evidence. He ruled that after eight years of use in Canada (since 1993), laser speed detection was no longer "new or novel" technology. The judge noted that laser principles were developed after World War II, are based on "immutable laws of physics," and are now used everywhere from CD players to space shuttle docking systems.

Most importantly, Justice Pockele criticized courts for imposing technical requirements without scientific justification. He found that in every case over eight years, no evidence had been presented to contradict the accuracy of laser devices. The judge stated: "If no such evidence has come before the Court in the last eight years, it is time to accept that LSDD technology is so well established that there is no evidence to the contrary."

The court specifically rejected the 30-day comparative testing schedule imposed in R. v. Wong, calling it "a time period without any scientific or technical validity." Justice Pockele found that requiring routine comparative testing against radar flew in the face of uncontradicted expert evidence that such testing was unnecessary.

Key Takeaway

Laser speed detection evidence no longer requires comparative testing against radar devices to be admissible in Ontario courts.

This decision effectively eliminated a major defence strategy for speeding tickets. Self-represented defendants can no longer challenge laser evidence simply by arguing that police failed to conduct regular comparative testing against radar devices.

R v Newbury

Unreported

Ontario Court of Justice 22 September 2008 speeding

R. v. Newbury

[2008] O.J. No. 5700
Ontario Court of Justice — J.R. Cottrell J.P. | September 22, 2008


Background

Timothy Newbury was caught doing 84 km/h in a 50 km/h zone on eastbound Danforth Avenue in Toronto on July 8, 2007. A police officer used a laser device to clock his speed and pulled him over. The officer identified Newbury by his valid Ontario driver's license and never lost sight of the vehicle from the time he took the reading until the traffic stop.

Newbury pleaded not guilty and took it to trial. What seemed like a straightforward speeding case quickly unraveled when his agent, Mr. Riddell, started digging into how the officer actually tested his laser device and what he bothered to write down in his notes.

Issues

  1. Did the officer properly test the laser device according to manufacturer specifications?
  2. Were the officer's notes so inadequate that they violated the defendant's Charter rights to disclosure and full answer and defence?

The Laser Testing Failure

The officer testified that he was trained and qualified to use the laser, and that he tested it before and after use according to "manufacturer's specifications." Problem was, when defence counsel showed him the actual manufacturer's manual (which had been provided in disclosure), it became clear the officer was doing many of the tests completely wrong.

The court relied on three POA appeal decisions — R. v. Niewiadomski, R. v. Wilkins, and R. v. Martin — all holding that when officers don't fully comply with testing and operational procedures, the laser reading becomes suspect. The judge found the officer's non-compliance with manufacturer specifications created reasonable doubt about the accuracy and reliability of the device.

The Disclosure Problem

The officer's notes were pathetic — "very brief and quite sparse," only about two and a half sentences long, described by the judge as "little more than cryptic jottings." Virtually everything the officer testified to in court wasn't in his notes and hadn't been disclosed to the defence.

The defence argued this violated Newbury's section 7 Charter rights, citing R. v. Karunakaran where Justice Armstrong said officers were essentially "disclosing the case during examination-in-chief" when their notes were inadequate. The judge agreed, noting that in this era of full disclosure, it's unacceptable for officers to say "I didn't note it because I would remember it." As Justice Feldman put it in R. v. Lozanovski: "significant facts be recorded by police and not left to the whim of memory."

Key Takeaway

Sloppy police work on two fronts — improper device testing and inadequate note-taking — can destroy even a straightforward speeding case.

Always request full disclosure and carefully review the manufacturer's manual for any technical device used against you. If the officer's notes are sparse and his testimony goes well beyond what's written down, you may have a Charter argument that your right to make full answer and defence has been violated.

R v Niewiadomski

[2004] O.J. No. 478

Ontario Court of Justice 12 February 2004 speeding

R. v. Niewiadomski

[2004] O.J. No. 478
Ontario Court of Justice — Schnall J. | February 12, 2004


Background

On September 11, 2001, Andrzej Niewiadomski was driving on Highway 401 when Constable Arnett clocked him at 128 km/h in a 100 km/h zone using a radar device. Niewiadomski was charged with speeding and convicted at trial. He appealed his conviction to the Ontario Court of Justice.

At trial, the defence called no evidence but thoroughly cross-examined Constable Arnett about his radar training and how he operated the device that day. What emerged was a litany of problems with both the officer's qualifications and his compliance with the manufacturer's specifications.

Issues

  1. Can courts take judicial notice that radar devices accurately measure vehicle speed?
  2. Was there sufficient evidence that the officer was competent, the device was working properly, and it was operated correctly?
  3. Did the Justice of the Peace err in convicting despite reasonable doubt about the radar evidence?

The Radar Evidence Problems

The cross-examination revealed serious gaps in the Crown's case. Constable Arnett had no notes about what tests he performed on the device that day and no recollection whether the radar completed its internal diagnostic tests. He was only 100 feet behind Niewiadomski's vehicle when he got the reading, despite manufacturer specifications requiring a minimum 250-foot distance. He couldn't explain the significance of the radar "blanking out" feature mentioned in the manual, and he'd tested the device on Highway 401 "where there is traffic all the time" instead of in a traffic-free zone as prescribed.

Most damaging was Arnett's training. He received instruction from two OPP officers described as "qualified radar instructors," but his evidence was vague about what qualifications those trainers actually possessed. The court found this evidence insufficient to establish his competence to operate the device or testify about its reliability.

The court confirmed that while judicial notice can be taken of radar technology's general reliability, this only applies when there's uncontradicted evidence about the operator's qualifications and the device's proper operation. Here, the cross-examination had contradicted both elements, raising reasonable doubt about the accuracy of the 128 km/h reading.

Key Takeaway

Cross-examination that exposes an officer's failure to follow manufacturer specifications and inadequate training can defeat radar evidence, even without calling defence witnesses.

Self-represented defendants facing radar-based charges should focus their cross-examination on the officer's specific training credentials, whether proper testing procedures were followed, and compliance with manufacturer distance and operational requirements.

R v Potts

British Columbia Supreme Court 13 April 2006 speeding

R. v. Potts

[2006] B.C.J. No. 849, 2006 BCSC 592
British Columbia Supreme Court — D.M. Smith J. | Heard April 3, 2006, Judgment April 13, 2006


Background

On September 19, 2004, Randall Richard Potts was driving northbound on the Coquihalla Highway near Kamloops when Constable Monson clocked his vehicle at 141 km/h using radar. The officer was positioned facing southbound, activated his radar gun, then made a U-turn to pursue and stop Potts' vehicle about five minutes later. Potts was issued a violation ticket for speeding contrary to a posted highway sign of 110 km/h under section 146(3) of the Motor Vehicle Act.

Potts disputed the ticket, putting the Crown to the strict proof of every element of the offence. At trial, the Justice of the Peace accepted the officer's evidence about Potts' speed over the defence witnesses, who had testified that Potts was driving the speed limit. However, the case turned on a different issue: whether the Crown had proven that speed limit signs were actually posted on that stretch of highway.

Issues

  1. Whether the Crown proved beyond a reasonable doubt that Potts was speeding
  2. Whether the Crown proved beyond a reasonable doubt that regulatory speed limit signs were in place and unobstructed

The Missing Evidence of Speed Limit Signs

This case highlights a critical difference between section 146(1) and 146(3) of the Motor Vehicle Act. Section 146(1) creates presumptive speed limits (50 km/h in municipalities, 80 km/h outside), but section 146(3) requires proof that a posted sign was actually in place. Constable Monson testified that the signs "were in place" but when cross-examined, admitted he had no personal recollection of the incident and was relying solely on his "standard practice" of checking that signs were visible before setting up radar.

The problem was in the details. The officer never claimed he undertook this practice every time he set up radar — he simply described it as his general approach. The judge found this insufficient to establish the essential element beyond a reasonable doubt. Unlike certificate cases where an officer formally attests that signs were in place "throughout those hours of operation, on that date," Monson's vague reference to standard practice left room for reasonable doubt about whether he had actually verified the signs on this specific occasion.

Key Takeaway

For section 146(3) speeding charges, the Crown must prove that speed limit signs were actually posted — and an officer's vague testimony about "standard practice" isn't enough.

If you're charged under section 146(3), always put the Crown to the strict proof of sign placement. Ask the officer on cross-examination whether they have any specific recollection of checking the signs on your particular date, or whether they're just relying on general practice.

R v Proctor

Unreported

Ontario Court (Provincial Division) 6 February 1997 speeding

R. v. Larry C. Proctor

Inform. No. 999 00 22079903-00
Ontario Court (Provincial Division) — His Honour Judge H.E. Zimmerman | February 6, 1997, at Newmarket, Ontario


Background

Larry Proctor was charged with speeding under section 128 of the Highway Traffic Act. At trial, the police officer testified that he had tested the radar "before and after the incident" but provided no specific information about when these tests occurred. Defence counsel Mr. Dullege argued that the case of Ziara required more specific evidence about the timing of radar testing — and he told the Justice of the Peace that he had argued this same case before her recently.

After hearing submissions, the Justice of the Peace convicted Proctor. In her reasons for judgment, she stated that she didn't know the Ziara case that defence counsel had referenced. Proctor appealed the conviction.

Issues

  1. Was the evidence about radar testing sufficient without specific timing details?
  2. Did the Justice of the Peace err by failing to consider the Ziara case law?

The Radar Testing Evidence

The officer's evidence was that he "tested it before and after the incident." But as Judge Zimmerman noted, this could mean anything — the same day, the same week, or even the same month. The Ziara case established that there must be evidence of "reasonable proximity" between the testing and the actual use of the radar device.

Judge Zimmerman found this vague testimony created "that element of doubt" and was not sufficient evidence to resolve the timing question "in the mind of the Justice of the Peace." Without knowing when the radar was actually tested, the court couldn't determine if it was accurate when used to catch Proctor speeding.

The Justice of the Peace's Error

More troubling was what happened after the legal arguments. Defence counsel had specifically told the Justice of the Peace that he had argued Ziara before her recently, and that it was a Provincial Court of Appeal decision requiring reasonable proximity for radar testing. Instead of asking for clarification or requesting a copy of the case, the Justice of the Peace simply stated in her judgment that she didn't know the case — and then convicted anyway.

Judge Zimmerman found this was legal error. The Justice of the Peace was bound by the Ziara decision and should have either refreshed her memory or obtained a copy of the case before rendering judgment. Her failure to consider binding case law, combined with the insufficient radar evidence, made the conviction unsafe.

Key Takeaway

Vague police testimony about radar testing "before and after" an incident is not enough — you need specific timing evidence.

If an officer can't say when they tested their radar equipment, there's reasonable doubt about whether it was accurate when they caught you speeding. And if you cite binding case law to a Justice of the Peace, they can't simply ignore it because they don't remember the decision.

R v Puncher

[2007] ONCJ 274

Ontario Court of Justice 25 May 2007 speeding

R. v. Puncher

2007 ONCJ 274
Ontario Court of Justice — Justice of the Peace M.A. Cuthbertson | May 25, 2007


Background

On August 17, 2006, at 6:54 AM, Officer Gray was driving his unmarked police cruiser at 50 km/h on County Road 52 in Wellington County when he spotted Allan Puncher approaching from behind on a Harley Davidson motorcycle. The road had a posted speed limit of 50 km/h. Officer Gray activated his radar unit and locked in the motorcycle's speed at 82 km/h — but used his discretion to charge Puncher with the lesser speed of 79 km/h under section 128 of the Highway Traffic Act.

Officer Gray was a qualified radar operator who testified that he had tested the radar unit both before and after the incident (at 5:37 AM and 7:01 AM) according to the manufacturer's instructions, and both tests showed the device was working properly. Puncher was represented by counsel and chose not to call any evidence.

Issues

  1. Can a reasonable doubt be created through cross-examination alone, without calling defence evidence?
  2. Was the radar device proven to have been operating accurately?

The Fatal Gap in Officer Knowledge

Defence counsel R. Burd focused his cross-examination on the radar's 'road test' — a key part of the manufacturer's testing procedure. When asked what minimum speed was required for this road test, Officer Gray testified: 'I can't recall. I believe it's somewhere in the neighbourhood of 30 kilometres per hour.' When pressed further about whether the required speed could be higher or lower, the officer admitted: 'It could be.'

The prosecutor argued that this uncertainty couldn't create reasonable doubt because the defence hadn't led any evidence about what the manufacturer's instructions actually required. Justice of the Peace Cuthbertson disagreed, citing several appellate decisions including R. v. Koumoudouros and R. v. Niewadomski that confirmed reasonable doubt can be raised through cross-examination of Crown witnesses.

The court applied the reasoning from R. v. Vancrey, where the Ontario Court of Appeal held that radar/laser evidence requires proof that the device was tested 'in accordance with the manufacturer's instructions.' The JP concluded that for an officer to properly test according to those instructions, the officer must actually know what those instructions are. Officer Gray's uncertainty about the required testing speed meant the Crown failed to prove the device was operating accurately.

Key Takeaway

Police officers must know the specific details of manufacturer testing requirements, not just perform what they think the tests should be.

This case shows that effective cross-examination can expose gaps in an officer's knowledge of radar testing procedures. Even without calling your own evidence, you can create reasonable doubt by demonstrating that the officer doesn't actually understand the technical requirements they're supposed to follow.

R v Schlesinger

2007 ONCJ 266

Ontario Court of Justice 4 May 2007 speeding

R. v. Schlesinger

[2007] O.J. No. 2365
Ontario Court of Justice — Justice of the Peace M.A. Cuthbertson | May 4, 2007


Background

On August 4, 2006, at 11:24 AM, OPP Officer Brazier was running laser speed enforcement on Highway 6 north in Puslinch township. He spotted David Schlesinger's vehicle travelling at what looked like a high rate of speed. The officer locked his laser device onto the vehicle from 404.8 metres away and got a reading of 132 km/h in an 80 km/h zone. Using his discretion, he charged Schlesinger with speeding at 129 km/h under section 128 of the Highway Traffic Act.

At trial, Officer Brazier testified that he was a qualified laser operator and instructor. But when asked about testing the device before the stop, things got messy. He initially said he tested it at 11:25 AM — which was impossible since that was *after* he'd already clocked Schlesinger at 11:24 AM. Unable to read his own notes properly, the officer fell back on saying it was his "usual practice" to test before enforcement stops, so he "must have" done it that day. Schlesinger admitted he was speeding, but said he was "probably" only going 100-110 km/h and hadn't checked his speedometer.

Issues

  1. Is it necessary for laser devices to be tested both before and after speed enforcement stops?
  2. Can a court accept an officer's "usual practice" as proof that proper testing was actually done?
  3. Is a defendant's admission of speeding sufficient for conviction without proof of the specific speed?

The Laser Testing Requirements

Justice Cuthbertson was clear: following the Ontario Court of Appeal decision in R. v. Vancrey, laser devices must be tested both before and after speed enforcement operations to prove the device was working accurately "at the time." This isn't optional — it's a legal requirement for the Crown to establish an evidentiary foundation for conviction.

But here's where it gets interesting. The court distinguished between simple devices (like breathalyzer mouthpieces) and complex electronic equipment (like laser devices). While some courts have accepted "usual practice" evidence for simple visual inspections, laser testing involves "four separate tests" requiring "strict adherence to manufacturer's instructions" and "conscious and explicit effort." The court set a higher standard: officers need to provide specific evidence that tests were done at specific times, not just rely on general practices.

Why "Usual Practice" Wasn't Enough

The court examined conflicting case law on whether "usual practice" evidence can prove specific actions occurred. While some appellate decisions like R. v. Thompson and R. v. Roshani-Kalkhoran suggested trial judges could accept usual practice evidence, other cases like R. v. Lounsbury and R. v. Niewiadomski rejected it as insufficient proof beyond a reasonable doubt.

Justice Cuthbertson sided with the stricter approach, requiring: (a) evidence that tests were done by a qualified officer according to manufacturer specifications, and (b) evidence of specific times when tests were conducted both before and after the stop. Since Officer Brazier provided no specific time for his pre-stop testing, the court refused to accept his "usual practice" claim.

The Defendant's Admission Problem

Even though Schlesinger admitted to speeding, the court applied R. v. Morin from the Supreme Court of Canada: every element of an offence must be proven beyond a reasonable doubt. Schlesinger's statement that he was "probably" going 100-110 km/h was just an opinion, made more uncertain by his use of "probably" and the fact he hadn't checked his speedometer. Since the laser evidence was excluded and no other speed evidence existed, the Crown couldn't prove the actual speed — an essential element of the offence.

Key Takeaway

Police officers can't rely on "usual practice" to prove they properly tested complex speed measurement devices — they need specific evidence of actual testing at specific times.

For self-represented defendants facing laser-based speeding charges, this case shows the importance of challenging the Crown's evidence about device testing. Ask specific questions: When exactly was the device tested? What were the results? Can the officer point to notes showing specific testing times? Generic claims about "usual practice" may not be enough to prove the device was working properly when you were caught.

R v Sim

[1988] O.J. No. 2250

Ontario Court of Appeal 11 October 1988 speeding

R. v. Sim

[1988] O.J. No. 2250
Ontario Court of Appeal — Robins, Tarnopolsky and Finlayson JJ.A. | October 11, 1988


Background

Dwight Donald Sim was charged with speeding after a police officer used radar to measure his vehicle's speed. At trial, Sim argued that the Crown had failed to establish a proper case because they didn't prove the radar device was actually capable of accurately measuring vehicle speeds. The justice of the peace convicted Sim anyway, and he appealed to the Ontario Court of Appeal.

This case was part of a larger legal battle in the 1980s over what the Crown needed to prove to use radar evidence in speeding prosecutions. Some defendants were arguing that it wasn't enough for police to just test the radar — they had to prove the device itself was scientifically capable of accurate speed measurement.

Issues

  1. Must the Crown prove that a radar device is capable of accurately measuring vehicle speeds?
  2. What evidence is required to establish a prima facie case for speeding based on radar?

The Radar Evidence Requirements

The Court of Appeal firmly rejected Sim's argument in a brief but decisive ruling. The court found that the Crown had presented sufficient evidence because: (1) the police officer tested the radar unit both before and after measuring Sim's speed, and (2) there was evidence showing the officer was familiar with the radar unit and knew how to use it properly.

The court explicitly stated they could find "no error in law on the part of the justice of the peace." This ruling aligned Ontario law with the practical reality that police officers aren't radar engineers — they just need to know how to operate the equipment and verify it's working correctly through testing procedures.

The Sim decision effectively shut down a line of defence arguments that had been gaining traction in other provinces, particularly Alberta, where courts had required more extensive proof of radar accuracy. Ontario took a more streamlined approach, focusing on proper testing and operator competence rather than abstract scientific capabilities.

Key Takeaway

Testing the radar before and after your speed measurement, plus officer familiarity with the device, is enough for the Crown to prove their speeding case.

Don't expect to beat a radar ticket by arguing the Crown needs to prove the scientific accuracy of radar technology itself. Focus instead on whether the officer actually performed the required tests or was properly trained on the specific device used.

R v Smith

Unreported

Unknown speeding

R. v. Smith

Provincial Court Decision
Provincial Court of Ontario — Date not specified in manual


Background

This case involves a speeding ticket issued using a UltraLyte LR B laser speed detection device. The UltraLyte LR B is a handheld laser speed measurement device manufactured by Laser Technology Inc. that uses infrared laser signals to measure vehicle speeds. The device is designed to meet FDA eye safety requirements and is classified as eye-safe to Class 1 limits, meaning virtually no hazard is associated with directly viewing the laser output under normal conditions.

The manual reveals critical information about the device's operation and potential defenses. The UltraLyte LR B has a maximum measurement distance of about 3280 feet (1000 meters) and includes features like a built-in Weather Filter for adverse conditions, a sighting scope with red aiming dot, and various test modes to verify the instrument's accuracy.

Issues

  1. Whether proper testing and calibration procedures were followed for the laser device
  2. Whether the officer was properly trained in the device's operation and limitations
  3. Whether environmental factors affected the accuracy of the speed measurement

The Laser Technology Evidence

The UltraLyte LR B manual provides extensive detail about required testing procedures that officers must follow. The device includes five different tests: Display Integrity Test, Scope Alignment Test, Reference Frequency Test, Fixed Distance Test, and Delta Distance Test. The manual specifically states that some of these tests are factory-defined options that may not be included on all units, and recommends that confidence checks be performed each time the instrument is used.

Critical to many defenses is the device's susceptibility to environmental interference. The manual warns about the "cosine effect" — when the target vehicle is moving at an angle to the instrument's position, the measured speed will be less than the vehicle's true speed. The manual provides detailed charts showing how this effect varies based on distance and angle, and notes that "the larger the angle, the lower the measured speed." The device also includes a Weather Filter specifically because "moisture is reflective" and weather conditions can affect laser signals.

Key Takeaway

Laser speed detection devices require specific testing procedures and are subject to environmental limitations that can affect their accuracy.

Self-represented defendants should request disclosure of all testing records, operator training certificates, and environmental conditions at the time of measurement. The technical manual reveals numerous potential points of challenge regarding proper operation and accuracy of laser speed detection evidence.

R v Taman

Unreported

Ontario Court (Provincial Division) 12 March 1998 speeding

R. v. A. Taman

March 12, 1998
Ontario Court (Provincial Division) — Judge R.E. Bogusky | Newmarket, Ontario


Background

Amos Taman was charged with speeding under section 128 of the Highway Traffic Act. At trial, the Crown called Sergeant Grenville to testify about operating a laser device to measure vehicle speeds. What should have been a routine traffic case became anything but when the officer's qualifications — or lack thereof — came under scrutiny.

The Crown also attempted to introduce evidence from other Alberta cases involving radar technology, hoping to establish that laser devices were reliable and accurate for measuring vehicle speeds.

Issues

  1. Whether the officer was qualified to operate the laser speed detection device
  2. Whether evidence from other jurisdictions could establish the reliability of laser technology
  3. Whether the Crown had proven the speeding charge beyond a reasonable doubt

The Qualification Problem

The case fell apart when Sergeant Grenville admitted under cross-examination that he had never actually been qualified to operate the laser device according to the manufacturer's specifications. Despite years of experience using radar devices, he had not completed the proper training for this specific laser unit. The court found this devastating to the Crown's case.

Judge Bogusky was clearly frustrated with what he saw as sloppy police work. The decision reveals a pattern of officers using devices they weren't properly trained on, creating a "garbage in, garbage out" situation for the courts. The judge noted that without proper qualifications, there was no foundation for the officer's evidence about the device's accuracy.

The Alberta Evidence Gambit

The Crown tried to salvage the case by introducing evidence from Alberta court decisions that had accepted laser technology as reliable. Judge Bogusky firmly rejected this approach, noting that evidence must stand on its own merits in each case. You can't prove your radar worked by pointing to someone else's radar in another province.

The court emphasized that each case requires proper foundation evidence — qualified operators, properly functioning equipment, and accurate readings. Generic judicial notice of technology isn't enough when the specific officer and specific device haven't been properly established.

Key Takeaway

An officer's experience with similar devices doesn't automatically qualify them to operate every speed detection device.

Self-represented defendants should ask detailed questions about the officer's specific training and qualifications for the exact device used. The Crown must prove not just that the technology works in general, but that this particular officer was qualified to use this particular device on this particular day.

R v Tang

Unreported

Ontario Court of Justice (Provincial Division) 5 February 1996 speeding

R. v. Tang

P.D.N. 22964599
Ontario Court of Justice (Provincial Division) — His Worship M. Houle | February 5th, 1996


Background

On December 8th, 1995, Roderick Tang was driving his black BMW 525 eastbound on Highway 401 in Charlottenburg Township when OPP Officer Mireille Desforges clocked him at 137 km/h in a posted 100 km/h zone using radar equipment. Tang was charged under section 128 of the Highway Traffic Act with speeding 30 km/h over the limit.

Here's where things got interesting: Officer Desforges served Tang with the offence notice at the roadside, but she had forgotten to fill in the time of the offence on the certificate. About 30 seconds after returning to her patrol vehicle, she realized her mistake and wrote "2:22 p.m." on her copy of the certificate. The problem? Tang's copy — the one he was served with — still showed no time.

Issues

  1. Does a certificate of offence that is amended after service to the defendant remain valid?
  2. Can missing information on a certificate be added after the defendant has already been served?

The Post-Service Amendment Problem

Defence agent M. Warsaw argued that the certificate was fatally flawed because information had been added after service. He cited two Brampton Provincial Court cases where certificates were quashed for similar post-service changes. The Crown prosecutor Al Peeters countered with section 90 of the Provincial Offences Act, which states that "the validity of any proceeding is not affected by any irregularity or defect in the substance or form of the summons."

The court heard that Officer Desforges had contacted the Crown about the missing time only on the morning of trial — well after the notice of trial had been sent to the defence. This timing became crucial to the court's analysis. The judge noted that while section 90 provides some protection for minor defects, there are limits to what can be cured after the fact.

His Worship M. Houle found that the post-service amendment created a material change to the certificate that rendered it improper. The court was particularly concerned that the defendant had been served with an incomplete document, and that attempts to remedy this defect came too late in the process.

Key Takeaway

A certificate that is materially changed after service cannot be saved by section 90 of the Provincial Offences Act.

If you notice that important information is missing from your offence notice, or if you discover the prosecution has added information after you were served, this could be grounds for dismissal. The courts will not allow the Crown to serve you with an incomplete document and then fill in the blanks later.

R v Tummillo

[1998] 9 W.W.R. 750

Manitoba Court of Appeal 17 June 1998 speeding

R. v. Tummillo

[1998] M.J. No. 311
Manitoba Court of Appeal — Philp, Twaddle and Helper JJ.A. | June 17, 1998


Background

Sabino Tummillo was caught speeding by a police officer using a Laser Speed Meter LTI-20-20. When the officer aimed the device at Tummillo's vehicle, it recorded a speed well in excess of the speed limit. At trial, the Crown tried to prove the laser device was working properly by having the officer testify that he conducted three tests: a fixed-distance zero-velocity test, a scope alignment test, and a display test. The officer explained these tests were meant to satisfy him that the device was accurately measuring speed, locking onto the right target, and communicating measurements properly.

Tummillo was convicted at trial, and that conviction was upheld on summary conviction appeal. But he wasn't done fighting — he appealed to the Manitoba Court of Appeal, arguing there was no proper evidence that the speed-timing device was actually in good working order.

Issues

  1. Was there sufficient evidence to prove the laser speed detection device was in good working order?
  2. Can a police officer's testimony about conducting tests establish a device's accuracy without expert evidence or manufacturer approval?

The Foundation Problem

Under s. 255(1) of Manitoba's Highway Traffic Act, speed-timing device evidence is admissible if two conditions are met: the device must be approved by the Minister of Justice, and the court must be satisfied it was in good working order when the reading was taken. The first condition was clearly met — the LTI-20-20 was an approved device. But the second condition? That's where things fell apart.

The officer wasn't qualified as an expert witness, so his opinion about what the tests proved was inadmissible. More importantly, there was no evidence that these three tests were actually sufficient to establish the device was working properly. Justice Twaddle noted the logical gap: "how a test of the device's ability to record a stationary object as one that is not moving proves it to be functioning properly when measuring the speed of a moving object." Without expert evidence or proof that the manufacturer approved these specific tests, the officer's testimony proved nothing.

The court emphasized that s. 255(4) of the Act specifically provides for qualified testers to certify device accuracy — but no such tester had been appointed in Manitoba. The Crown can't simply substitute an unqualified police officer's testing without proving those tests actually work.

Key Takeaway

Police officer testimony about device testing is worthless without expert evidence or manufacturer approval of the testing procedures.

If you're facing a speeding charge based on laser or radar evidence, demand to see proof that the device testing was conducted by qualified personnel using manufacturer-approved procedures. A cop saying "I tested it and it seemed fine" isn't evidence of anything.

R v Vancrey

[2000] O.J. No. 3033

Ontario Court of Appeal 18 August 2000 speeding

R. v. Vancrey

[2000] O.J. No. 3033
Ontario Court of Appeal — Laskin, Feldman and O'Connor JJ.A. | August 18, 2000


Background

Kelly Vancrey was caught speeding on Highway 402 in Adelaide Township on February 22, 1998. O.P.P. Officer Gillies used an L.T.I. 20-20 Marksman Laser Speed Detection Device to clock her at 136 km/hr in a 100 km/hr zone. Officer Ormsby stopped her vehicle and issued the ticket. Vancrey was convicted under section 128 of the Highway Traffic Act and appealed all the way to the Ontario Court of Appeal.

The Crown consented to the appeal because it raised an issue of public importance: what evidence is needed to prove a laser speed detection device is accurate? Unlike breathalyzers or some radar units, laser devices aren't specifically approved by Ontario statute, so the Crown has to prove both that the technology works and that the specific device was working properly on the day of the offence.

Issues

  1. What evidence must the Crown present to prove a laser speed detection device accurately measured a vehicle's speed?
  2. Was the evidence sufficient in this case to support the conviction?

The Laser Evidence Problem

Officer Gillies performed the manufacturer's four-part test twice on February 22 — once at 7:55 a.m. and again at 4:37 p.m. The tests included a self-test, display test, scope test (pointing the laser at objects to confirm the beam worked), and a distance-velocity test (measuring a wall at 19.8 meters, which read correctly for distance and showed 0 km/hr for speed).

But here's the problem courts identified: testing that a wall reads "0 km/hr" doesn't prove the device can accurately measure a moving vehicle. The justice of the peace agreed this fourth test was inadequate. However, Officer Gillies had done something extra — in late January or early February 1998, he compared his laser readings with radar readings on the same vehicles. Over 30-45 minutes, he tested at least 6 vehicles with both devices simultaneously. The readings were identical every time.

The Court of Appeal found this comparison test provided the necessary "circumstantial guarantee of trustworthiness." The radar comparison, done 3-4 weeks before the offence, combined with the manufacturer's tests on the day of the offence, was sufficient evidence that the laser device was accurate.

Key Takeaway

Laser speeding tickets can be defended by challenging whether the Crown proved the device's accuracy, but comparison testing with radar can satisfy this burden.

This case shows that while laser technology isn't automatically accepted by courts, proper testing procedures can establish reliability. The court noted it would be "most helpful" to have expert evidence about laser methodology, suggesting this remains a potential area for defence challenges.

R v Wilkins

[2006] O.J. No. 5366

Ontario Court of Justice 12 December 2006 speeding

R. v. Wilkins

[2006] O.J. No. 5366
Ontario Court of Justice — L. Klein J. | December 12, 2006


Background

On May 20, 2006, Constable Rod Roberts of the Northeast Traffic and Marine Unit was running radar on Highway 400 in Sequin Township. At 6:16 a.m., he spotted a blue Subaru speeding northbound, closing fast on the car in front of it. Roberts aimed his lidar gun and got a reading of 151 km/h in a 100 km/h zone, locking it in at a distance of 513.8 metres. He pulled over the driver, Mark Wilkins, and issued a speeding ticket under section 128 of the Highway Traffic Act.

Roberts testified that he was properly trained and qualified on the lidar equipment, having been trained in April 2003 and re-qualified in October 2004. He said he conducted the manufacturer-approved tests both before and after his shift and the equipment was working properly. Wilkins was convicted at trial and appealed to the Ontario Court of Justice.

Issues

  1. Can a lidar reading be considered accurate when the officer was not trained using the original manufacturer's manual?
  2. What evidence is required to establish that radar/lidar equipment was properly tested according to manufacturer specifications?

The Manual Problem

Here's where the Crown's case fell apart. In cross-examination, Constable Roberts admitted he had never seen the original manual provided by the manufacturer of the lidar device. He had only worked with a photocopy of a manual that was supplied by the Ministry of Transportation — not directly from the manufacturer. The officer could not testify that his training or testing procedures actually followed the manufacturer's specifications because he had no knowledge of what those original specifications were.

Justice Klein noted that while photocopies are generally reliable reproductions, the law requires more than just a copy when it comes to radar evidence. The Crown must prove that the operator is qualified, that the device was tested properly both before and after use, and that those tests showed the instrument was accurate. Without evidence that the testing followed the actual manufacturer's specifications, this foundation crumbled.

The judge cited R. v. Niewiadomski for the principle that "cross-examination which elicits the admission of non-compliance with the manufacturer's specifications and directions as to testing and operations should raise a reasonable doubt." That's exactly what happened here — Roberts admitted he had no way of knowing if his procedures matched what the manufacturer actually required.

Key Takeaway

Radar and lidar evidence can be challenged by questioning whether the officer actually followed the manufacturer's original testing procedures.

If you're facing a radar-based speeding charge, ask the officer in cross-examination whether they've seen the original manufacturer's manual, not just a photocopy or summary provided by their training department. The Crown must prove compliance with the actual manufacturer's specifications — educated guesses and secondhand procedures aren't enough.

Ville de Baie-Comeau v D'Astous

1992 CanLII 2956 (QC CA)

Quebec Court of Appeal 25 March 1992 speeding

Ville de Baie-Comeau v. Yves D'Astous

1992 CanLII 2956 (QC CA)
Quebec Court of Appeal — Judges McCarthy, LeBel, and Gendreau | March 25, 1992


Background

Officer Picard of the Ville de Baie-Comeau was operating a radar gun on Boulevard Laflèche when he spotted Yves D'Astous's car traveling at what appeared to be excessive speed. The radar registered 114 km/h in a 50 km/h zone — more than double the speed limit. Picard intercepted D'Astous and issued a speeding ticket.

D'Astous fought the charge. The Court of Sessions of the Peace acquitted him, finding that while he likely did exceed the speed limit, the prosecution hadn't proven their case beyond a reasonable doubt. The Superior Court upheld the acquittal on appeal, ruling that the radar evidence was insufficient. The City of Baie-Comeau then appealed to the Quebec Court of Appeal.

Issues

  1. What level of proof is required when radar evidence is used to establish speeding?
  2. Is radar technology a matter of judicial notice, or must its reliability be proven in each case?
  3. Was the evidence sufficient to prove D'Astous was speeding?

The Radar Evidence Gap

Judge Gendreau's analysis focused on a critical procedural flaw. Officer Picard had performed pre-operation tests on his radar unit using tuning forks, which showed the device was working properly. He had three years of radar experience and proper training. However, the evidence revealed a crucial missing piece: no post-operation test was conducted after the radar session ended.

The court ruled that radar technology itself is a matter of judicial notice — everyone knows radar exists and generally works. But that doesn't mean every specific radar reading is automatically reliable. The prosecution must prove that the particular device was accurate and functioning properly when it recorded the defendant's speed. This requires evidence that the operator was qualified, the device was tested before use, and crucially, that it remained accurate throughout the enforcement period.

The court explained that both pre- and post-operation testing are essential because they create a "circumstantial evidence sandwich" — if the radar worked before and after measuring the defendant's vehicle, a judge can reasonably conclude it was working accurately during the measurement. Without the post-test, that chain of reliability is broken.

Key Takeaway

Radar evidence requires proof that the device was tested both before AND after the enforcement session.

If you're challenging a radar-based speeding ticket, ask whether the officer conducted post-operation testing. Missing this crucial verification step can undermine the prosecution's entire case, even when the radar reading seems obviously accurate.
