Goodwin v. British Columbia (Superintendent of Motor Vehicles)

2015 SCC 46

Supreme Court of Canada 16 October 2015 impaired driving

Goodwin v. British Columbia (Superintendent of Motor Vehicles)

2015 SCC 46
Supreme Court of Canada — Karakatsanis J. (majority), McLachlin C.J. (dissenting in part) | October 16, 2015


Background

In 2010, British Columbia introduced the Automatic Roadside Prohibition (ARP) scheme — a dramatic shift from taking suspected drunk drivers to the station for breathalyzer tests to issuing immediate suspensions based solely on roadside screening devices. Under the scheme, a "fail" reading (over 0.08) resulted in an immediate 90-day licence suspension, vehicle impoundment, and over $4,000 in penalties and costs. A "warn" reading (0.05-0.08) triggered shorter suspensions.

Multiple drivers challenged the scheme after receiving prohibitions. Richard Goodwin failed to provide an adequate breath sample, while Jamie Chisholm, Carol Beam, and Scott Roberts all registered "fail" readings. Each faced the full consequences with extremely limited review options — the Superintendent could only consider whether they were "drivers" and whether the device registered the reading it claimed to register.

Issues

  1. Is the ARP scheme ultra vires (beyond) the province's constitutional authority as criminal law?
  2. Does the scheme violate Charter section 11(d) by creating an "offence" without presumption of innocence?
  3. Does the scheme violate Charter section 8 protection against unreasonable search and seizure?

The Section 8 Violation

The majority found the "fail" branch of the ARP scheme violated section 8. The critical flaw was reliability: roadside screening devices are known to produce false positives when mouth alcohol is present, yet the scheme provided no meaningful way to challenge the accuracy of the result. Unlike criminal proceedings where an ASD test merely provides grounds for a more reliable breathalyzer test at the station, the ARP scheme made the potentially unreliable roadside result determinative of serious consequences.

The court emphasized that while the government's purpose (preventing impaired driving deaths) was pressing and substantial, and the breath seizure was minimally intrusive, the absence of adequate review mechanisms rendered the scheme unreasonable. A driver could face "serious administrative sanctions without the precondition for the sanctions being met, and without any mechanism for redress." The scheme failed the minimal impairment test under section 1 because subsequent legislative amendments proved that better review procedures could be implemented without undermining the program's objectives.

Key Takeaway

Even regulatory schemes with important public safety goals must provide meaningful ways to challenge the accuracy of the evidence used against you.

While this case dealt with provincial driving prohibitions rather than Provincial Offences Act charges, it establishes that Charter section 8 protections apply when government relies on potentially unreliable testing methods without adequate safeguards for review and challenge.

R v Abdulatif

2017 ONSC

Ontario Superior Court of Justice 27 February 2017 possession of cocaine for the purpose of trafficking

R. v. Abdulatif

2017 ONSC, Court File No. CR-15-90000343-000
Ontario Superior Court of Justice — Himel J. | February 27, 2017


Background

On a busy Saturday afternoon in June 2014, Detective Constable Merritt was conducting plainclothes surveillance near Bellevue Square Park in Toronto's Kensington Market area. He observed Peter Mymuller (nicknamed "Bones") drinking a beer and smoking marijuana with friends, then walking over to a black Acura where Ibsa Abdulatif and Mohammed Hashimi were sitting. Merritt claimed he saw what appeared to be a "hand-to-hand" drug transaction between Mymuller and the two men in the car, though he admitted he couldn't see what was actually exchanged and was observing from across the street.

Based solely on this observation, Merritt called for backup to arrest the occupants of the vehicle for drug trafficking. When other officers arrived, they arrested both Abdulatif and Hashimi. During a search incident to arrest, police found cocaine on Abdulatif's person and cash in the vehicle. Abdulatif was charged with possession of cocaine for the purpose of trafficking contrary to the Controlled Drugs and Substances Act.

Issues

  1. Did the police have reasonable and probable grounds to arrest Abdulatif?
  2. Were Abdulatif's Charter rights under sections 8 and 9 violated?
  3. Should the evidence be excluded under section 24(2) of the Charter?

The Reasonable and Probable Grounds Analysis

Justice Himel found that Officer Merritt's observations fell far short of establishing reasonable and probable grounds for arrest. The court noted several critical problems with the officer's evidence: he never actually saw what was exchanged between the parties, he didn't follow Mymuller after the alleged transaction despite knowing where he lived, and he gave conflicting testimony about key details. Most importantly, when Merritt called for backup, he provided no specific details about his observations to the arresting officers — they simply arrested based on his general claim that grounds existed for a trafficking investigation.

The court emphasized that reasonable and probable grounds require both subjective belief by the officer and objective justification for that belief. Here, while Merritt may have subjectively believed a drug transaction occurred, the objective evidence was insufficient. The fact that this occurred in a known drug area and involved people with criminal histories wasn't enough to justify an arrest without observing an actual exchange of contraband.

Charter Violations and Exclusion of Evidence

Having found no reasonable grounds for arrest, Justice Himel concluded that Abdulatif's sections 8 and 9 Charter rights were violated — he was arbitrarily detained and subjected to unreasonable search and seizure. The court then applied the Grant framework to determine whether to exclude the evidence. While acknowledging that the cocaine evidence was reliable and important to the Crown's case, Justice Himel found that the seriousness of the Charter breaches and the impact on Abdulatif's liberty interests outweighed the public interest in adjudication on the merits.

Key Takeaway

Police cannot arrest someone for drug trafficking based on speculation and assumptions — they need to actually observe criminal activity.

This case demonstrates that even in high-crime areas, police must have concrete, objective evidence of criminal activity before making an arrest. Vague observations of "suspicious" behavior, combined with knowledge of someone's criminal history, will not satisfy the reasonable and probable grounds standard required for a lawful arrest.

R v Doroslovac

[2012] ONCA 680

Ontario Court of Appeal 10 October 2012 trafficking in cocaine

R. v. Doroslovac

2012 ONCA 680
Court of Appeal for Ontario — Winkler C.J.O., Laskin and Watt JJ.A. | October 10, 2012


Background

In May 2008, police were investigating Slavko Ilic and Milenko Doroslovac for drug trafficking. A Superior Court judge authorized police to intercept Ilic's telephone calls and other telecommunications. Police found a torn-up piece of paper in a movie theatre garbage can that contained the phone number (226) 220-6845 and instructions for operating the phone. They began intercepting communications on that number.

From intercepted text messages, police concluded that Ilic and Doroslovac were planning to meet at a commuter parking lot near Highways 6 and 401 to exchange drugs for money. Undercover officers watched the exchange, followed Doroslovac to Toronto, and saw him hand over a white plastic bag containing 3 kilograms of cocaine to another man at a coffee shop. Arrests followed.

At trial, the judge excluded the intercepted text messages as evidence and acquitted Doroslovac. The Crown appealed to the Ontario Court of Appeal.

Issues

  1. Did the trial judge correctly interpret the wiretap authorization regarding text message interception?
  2. Were the intercepted text messages properly excluded under s. 24(2) of the Charter?

The Wiretap Authorization Problem

The trial judge ruled that the text messages couldn't be used as evidence because police hadn't properly followed their wiretap authorization. The authorization allowed interception of communications from devices "believed on reasonable grounds to be used by [Ilic] and while being used by one of the persons named." The judge interpreted this to mean police needed certainty that Ilic was actually the person sending each text message at the time it was sent.

The Court of Appeal disagreed completely. Justice Watt explained that this interpretation made text message interception practically impossible — there's no "live" voice to monitor in a text message, and visual surveillance can't determine who's typing unless you're standing right next to them. The court found that paragraph 6e of the authorization specifically allowed interception of "non-oral telecommunications" (like text messages) without live monitoring or visual surveillance requirements.

The proper interpretation was that police only needed reasonable grounds to believe Ilic was using the phone generally, and that at the time of interception, either Ilic or another authorized person was using the device — not certainty about who was typing each specific message.

Key Takeaway

Courts will interpret wiretap authorizations to make them workable, not to create impossible standards that would defeat their purpose.

While this case deals with wiretap evidence rather than typical Provincial Offences Act matters, it shows how courts approach the interpretation of legal authorizations — they look at the document as a whole and reject interpretations that would make authorized activities practically impossible to carry out.

R v Fearon

2013 ONCA 106

Court of Appeal for Ontario 11 December 2014 robbery with a firearm

R. v. Fearon

2013 ONCA 106
Court of Appeal for Ontario — MacPherson, Armstrong and Watt JJ.A. | February 20, 2013


Background

Kevin Fearon was arrested for armed robbery after a jewellery vendor was held up at gunpoint at a Toronto flea market. During a pat-down search at the scene, police found Fearon's cell phone. Sergeant Hicks immediately examined its contents and discovered photographs of a gun and cash, plus a draft text message reading "We did it were the jewlery at nigga burrrrrrrrr." The phone wasn't password protected, so the officer could access everything by operating the keypad.

Hours later at the police station, officers continued searching through the phone for contacts and recent calls. They eventually got a search warrant months later, but by then the damage was done — Fearon's lawyer argued the original warrantless search violated his Charter rights and all the cell phone evidence should be thrown out.

Issues

  1. Does the common law power of "search incident to arrest" allow police to search the contents of a cell phone without a warrant?
  2. Should courts create a special "cell phone exception" requiring warrants for smartphone searches?
  3. If the search was illegal, should the evidence be excluded under s. 24(2) of the Charter?

The Cell Phone Search Doctrine

The Court of Appeal refused to carve out a special exception for cell phones. Justice Armstrong explained that under R. v. Caslake, police can search items found on an arrested person if they have "some reason related to the arrest" and that reason is "objectively reasonable." Here, police knew Fearon had accomplices and were looking for evidence about the gun's location, stolen property, and communications between co-conspirators.

The court distinguished this case from R. v. Polius, where a judge had required warrants for cell phone searches. In Polius, police had no reason to believe the phone contained relevant evidence. Here, given the nature of the robbery and the likelihood of accomplice communications, the search was reasonable. Crucially, Fearon's phone wasn't password protected — the photos and texts were "readily available to other users."

However, the court suggested the continued searching at the police station went too far. Once police had the incriminating evidence, they should have stopped and gotten a warrant for any further examination.

Key Takeaway

Police can search your unlocked cell phone immediately after arrest if they have reasonable grounds to believe it contains evidence of your alleged crime.

But if your phone is password protected or locked, police would need a warrant to crack it open. The court left the door open for future cases involving more sophisticated devices or different circumstances to potentially require warrants.

R v Hancin

Unreported

Ontario Provincial Court (Criminal Division) 18 August 1988 speeding

R. v. Hancin

Provincial Court (Criminal Division)
Newmarket Courthouse — Judge H.E. Zimmerman | August 18, 1988


Background

Michael Hancin was charged with speeding (121 km/hr in an 80 km/hr zone) and operating a motor vehicle with a radar warning device. The police officer had proper radar training, tested his equipment before and after the incident, and found a radar detector in Hancin's vehicle during a search. But there was one problem: nobody ever specifically testified that Hancin was operating a "motor vehicle" as defined by law.

The case also raised Charter issues about the search that led to finding the radar detector. The officer searched Hancin's vehicle based on reasonable grounds to believe it contained a radar warning device, then asked Hancin to produce the device from his vest pocket.

Issues

  1. Did the search for the radar warning device violate Hancin's Charter rights?
  2. Did the Crown prove beyond a reasonable doubt that Hancin was operating a "motor vehicle"?

The Charter Challenge Fails

Judge Zimmerman found no Charter breach. The officer had reasonable grounds to believe there was a radar warning device in the vehicle, which authorized a search under the Highway Traffic Act. The subsequent request for Hancin to produce the device from his pocket was a reasonable continuation of the lawful search. The judge noted this wasn't an unreasonable search and seizure situation.

The Fatal Flaw: Proving "Motor Vehicle"

Here's where things got interesting. While the evidence clearly showed someone was operating *some kind of vehicle* at high speed, nobody specifically testified that it was a "motor vehicle" within the legal definition. The officer gave detailed evidence about radar operation, speed readings, and the search — but never explicitly stated what type of vehicle was involved.

Judge Zimmerman acknowledged this stretched credulity: "it is very clear from the evidence that Mr. Hancin was operating a vehicle... there is room for doubt as to the nature of the vehicle." He noted it would be unlikely to find a soap box or muscle-powered vehicle reaching that speed on a highway, but the legal standard is proof beyond a reasonable doubt.

Key Takeaway

The Crown must prove every element of the offence, including seemingly obvious ones like vehicle type.

Even when common sense suggests an obvious conclusion, technical legal requirements matter. The prosecution's failure to establish this basic definitional element resulted in both appeals being allowed, despite strong evidence of speeding and radar detector possession.

R v McPhail

2011 ONCJ 315

Ontario Court of Justice 8 June 2011 impaired driving and over 80

R. v. McPhail

2011 ONCJ 315
Ontario Court of Justice — Justice J.A. Maresca | June 8, 2011


Background

David McPhail was arrested on September 21, 2008, for impaired driving and driving "over 80" in Brampton. After being brought to the 11 Division police station around 4:50 am, he was strip-searched by Officer Chris Allen and Officer Jason McCurley. The officers claimed the search was justified because they found a cell phone in McPhail's shoe during the booking process.

What made this case particularly troubling was how the truth emerged. During the first day of trial in September 2010, Officer McCurley repeatedly denied that any strip search had occurred, claiming he "wouldn't have done a strip search" for an impaired driving charge. Only after persistent questioning did he finally admit the search happened — and his story kept changing between court appearances.

Issues

  1. Did the strip search violate McPhail's section 8 Charter rights against unreasonable search and seizure?
  2. Should the breathalyzer evidence be excluded as a result of the Charter breach?

The Strip Search Analysis

Justice Maresca applied the Supreme Court's decision in R. v. Golden, which sets strict rules for strip searches. Police need reasonable and probable grounds to believe a strip search is necessary to find weapons or evidence related to the specific offence. Finding a cell phone in someone's shoe doesn't create those grounds — especially when the person has already been pat-searched and wand-searched with no results.

Officer Allen's justification was particularly weak: he claimed he'd read about cell phones that could fire bullets, so finding any cell phone justified stripping McPhail completely naked. The judge found this reasoning "fanciful" and noted that strip searches of impaired driving suspects are extremely rare. Multiple officers testified they'd never conducted strip searches for drinking and driving offences.

The court also found that several officers changed their descriptions of McPhail from "compliant" with "no issues" on the first day of testimony to "cocky," "arrogant," and "belligerent" on the second day — suggesting the search was conducted to humiliate McPhail rather than for legitimate investigative purposes.

The Cover-Up Attempt

What made the Charter breach especially egregious was the attempted cover-up. Officer McCurley initially lied under oath, claiming no strip search occurred. When confronted with the contradictions in his testimony, he admitted his first day of evidence was "wrong." The officers kept no notes about the search beyond a checkbox in the prisoner log, despite knowing it had occurred.

Justice Maresca found this attempted concealment made the police conduct "especially egregious" and weighed heavily in favor of excluding the breathalyzer evidence under section 24(2) of the Charter.

Key Takeaway

Police cannot strip search someone just because they don't like their attitude or found an unrelated item during booking.

When police abuse their power and then lie about it in court, judges will exclude crucial evidence — even in serious cases like impaired driving where society has a strong interest in conviction.

R v Paterson

[2017] SCC 15

Supreme Court of Canada 17 March 2017 possession of controlled substances for trafficking

R. v. Paterson

2017 SCC 15
Supreme Court of Canada — Brown J. (majority), Moldaver J. (dissenting) | March 17, 2017


Background

In November 2007, RCMP officers responded to a 911 call from Brendan Paterson's girlfriend in Langley, BC. After determining no one needed assistance, the officers smelled marijuana when Paterson opened his apartment door. He admitted to having some marijuana "roaches" inside. The officers told him they would seize the roaches on a "no case" basis — meaning they'd take them but not charge him.

When Paterson tried to close the door, Constable Dykeman blocked it with his foot and followed him inside, claiming officer safety concerns and fear the roaches would be destroyed. Once inside, the officers observed a bulletproof vest, handgun, and what appeared to be ecstasy pills in plain view. They arrested Paterson and obtained a telewarrant to search the apartment, discovering significant quantities of cocaine, methamphetamine, ecstasy, four loaded firearms, and over $30,000 in cash.

Issues

  1. Whether "exigent circumstances" under s. 11(7) of the Controlled Drugs and Substances Act justified the warrantless entry
  2. Whether evidence obtained from the warrantless search should be excluded under s. 24(2) of the Charter

The Exigent Circumstances Test

The Supreme Court clarified that "exigent circumstances" means urgency — not mere convenience or practicality. Section 11(7) of the CDSA allows warrantless searches only when exigent circumstances make obtaining a warrant "impracticable." The Court explained this requires two elements: (1) urgency calling for immediate police action to preserve evidence, officer safety, or public safety, and (2) that taking time to get a warrant would pose serious risk to those objectives.

The majority found no genuine urgency here. The prospect of Paterson destroying roaches that police planned to destroy anyway — with no legal consequences to him — didn't approach the threshold. The police had practical alternatives: arrest Paterson and get a warrant, or seek his consent to enter. The Court rejected the "no case" nature of the seizure as legally irrelevant to the exigency analysis.

Charter Breach and Exclusion of Evidence

Having found the search violated s. 8 Charter rights, the Court applied the Grant framework for excluding evidence. The majority emphasized that warrantless entry into a residence — where people have the highest expectation of privacy — represents serious state misconduct, even when police act in good faith. The legal principles governing residential searches were well-established, making the "no case" intention legally insignificant.

The dissenting judges argued the legal uncertainty around "no case" seizures should reduce the seriousness of the breach, noting that both the trial judge and Court of Appeal had found the search lawful. However, the majority concluded that admitting evidence from an unjustified residential search would bring the administration of justice into disrepute, despite the reliability of the evidence and seriousness of the charges.

Key Takeaway

Police cannot rely on minor drug offences to justify major Charter violations through warrantless home searches.

This decision reinforces that residential searches require the highest justification, and that police good faith or administrative convenience cannot override Charter protections. The "exigent circumstances" exception demands genuine urgency, not mere investigative efficiency.

R v Reeves

2018 SCC 56

Supreme Court of Canada 13 December 2018 possessing child pornography

R. v. Reeves

2018 SCC 56
Supreme Court of Canada — Karakatsanis J. (majority), Moldaver J. and Côté J. (concurring) | December 13, 2018


Background

Thomas Reeves shared a home with his common-law spouse Nicole Gravelle. After domestic assault charges and a no-contact order, Gravelle contacted police reporting she'd found child pornography on their shared computer. A police officer arrived without a warrant, and Gravelle signed a consent form allowing him to take the computer from the basement. The officer admitted he sought consent because he didn't believe he had reasonable grounds for a warrant.

Police held the computer for over four months without searching it, failing to report the seizure to a justice as required by s. 489.1 of the Criminal Code. When they finally got a search warrant, they found 140 images and 22 videos of child pornography. Reeves was charged with possession and accessing child pornography, but argued his Charter s. 8 rights were violated.

Issues

  1. Can police lawfully seize a shared computer from a home with only one co-owner's consent?
  2. Does the third-party consent doctrine from Cole apply to shared property?
  3. Should the evidence be excluded under s. 24(2) of the Charter?

The Shared Computer Seizure

The Supreme Court ruled that Reeves had a reasonable expectation of privacy in the shared computer, despite joint ownership. The majority rejected the "third-party consent" approach, holding that one person cannot waive another's Charter rights — even when they share property. Justice Karakatsanis emphasized that when you share a computer with family, you accept the risk they might access your data or even tell police about it, but not the risk that they can authorize police to physically seize the device.

The Court distinguished between the "tattletale risk" (someone telling police what they found) and the seizure risk (someone consenting to police taking shared property). The warrantless seizure violated Reeves' s. 8 rights because his spouse's consent couldn't override his constitutional protections. The Court noted this rule protects low-income individuals who are more likely to share computers.

Multiple Charter Breaches

Beyond the unlawful seizure, police committed several additional violations: they failed to report the seizure to a justice "as soon as practicable" under s. 489.1, detained the computer beyond the three-month limit in s. 490(2), and obtained the eventual search warrant through a "goal-oriented, misleading" affidavit that should never have been granted. The Court found these multiple serious breaches undermined public confidence in the rule of law.

Key Takeaway

Your roommate, spouse, or family member cannot give police permission to seize shared property — you both have Charter rights that must be respected.

This ruling strengthens privacy protections in shared living situations and confirms that police need proper grounds and warrants, not just consent from one co-owner, when seizing computers and other shared devices.

R v Telus Communications Co.

[2011] ONSC 1143

Ontario Superior Court of Justice 4 March 2011 general warrant challenge

Her Majesty the Queen v. Telus Communications Company

2011 ONSC 1143
Superior Court of Justice — Sproat J. | March 4, 2011


Background

Police obtained a General Warrant requiring Telus to produce all text messages sent and received by two subscribers on a daily basis for 30 days following the warrant's issuance. This wasn't your typical search warrant — it required Telus security analysts to review databases every morning at 11:00 a.m., export records into Excel documents, sort them chronologically, delete records outside the 24-hour timeframe, format the results, and email them to police by 2:00 p.m. the same day. For 30 days straight.

Telus pushes back hard, arguing this General Warrant was actually an illegal attempt to intercept private communications. They claimed police should have obtained proper wiretap authorization under Part VI of the Criminal Code for each day's communications, which requires much higher legal standards including proof that other investigative methods had failed. In the past few years, Telus had received about 10,000 court orders — only six had been in this unusual form.

Issues

  1. Does the General Warrant constitute an "interception" of private communications requiring wiretap authorization?
  2. Were conventional warrants available that would make the General Warrant improper?
  3. Was issuing the General Warrant in the best interests of the administration of justice?

The Interception Question

The court ruled that "interception" requires real-time capture of otherwise transient communications — not accessing stored data. Justice Sproat found that Telus routinely copies all text messages into databases for at least 30 days for troubleshooting purposes. The General Warrant was directed at these stored messages, not messages in transit from sender to receiver.

Telus argued that some messages would be "intercepted" because of delivery delays (like when someone's phone is turned off), but the court rejected this logic as "illogical and impractical." The judge noted that even a conventional production order for past messages could capture sent-but-not-delivered texts. The key distinction was that the warrant targeted stored database records, not live communications flowing through the network.

Conventional Warrant Availability

Under section 487.01(1)(c) of the Criminal Code, general warrants are only available if no other statutory provision could authorize the same investigative technique. The Crown conceded that police could have used conventional warrants for historical records, but argued that the specific technique of "prospective daily production" wasn't available through any other provision.

The court agreed, noting it would have been impractical to require police to obtain 14 separate daily warrants involving multiple justices of the peace with possible inconsistent approaches. The investigative technique of ongoing daily text message production simply couldn't be authorized under conventional warrant provisions.

Key Takeaway

Stored electronic communications are treated differently from live wiretaps — accessing databases doesn't require the same strict authorization as intercepting real-time communications.

This case shows how courts balance modern technology with existing legal frameworks, and how telecommunications companies can challenge warrants they believe exceed legal authority — but also demonstrates that law enforcement has broad powers to access stored digital communications through properly obtained general warrants.

R v Vu

[2013] 3 SCR 657

Supreme Court of Canada 7 November 2013 production of marijuana

R. v. Vu

2013 SCC 60, [2013] 3 S.C.R. 657
Supreme Court of Canada — Cromwell J. (unanimous) | November 7, 2013


Background

Thanh Long Vu was charged with marijuana production, possession for trafficking, and theft of electricity after police executed a search warrant at a Langley residence. BC Hydro had tipped off police that electricity was being diverted at the property. The police obtained a warrant to search for evidence of electricity theft, including "documentation identifying the owners and/or occupants of the residence." During the search, officers found a marijuana grow-op in the basement, plus two computers and a cellular phone in the living room.

Here's the problem: while the warrant mentioned searching for "computer generated notes," it didn't specifically authorize searching the actual computers. Police searched them anyway, finding MSN chat logs, Facebook accounts, photos, and other evidence linking Vu to the residence. The trial judge ruled this violated Vu's Charter rights and excluded most of the evidence, leading to acquittals on the drug charges.

Issues

  1. Did the search warrant properly authorize searching for ownership/occupancy documents?
  2. Did the warrant authorize police to search the computers and cellular phone?
  3. Should the evidence obtained from the computer searches be excluded?

The Digital Privacy Revolution

The Supreme Court made legal history by ruling that computers require specific, prior authorization before police can search them — even when found during an otherwise lawful search. Justice Cromwell explained that computers are fundamentally different from traditional "receptacles" like filing cabinets or drawers. They store massive amounts of personal information (a single terabyte can hold a million books), automatically generate data users don't know about, retain "deleted" files, and can access information stored anywhere in the world through internet connections.

The Court rejected the traditional rule that if police can search a place, they can search any containers found there. For computers, that assumption "simply cannot apply." Instead, police must specifically ask the authorizing justice for permission to search computers, explaining why they believe computers will contain the evidence they're seeking. If police find an unexpected computer during a search, they can seize it to preserve evidence, but they need a separate warrant to actually search its contents.

The Evidence Ruling

Despite finding the computer searches violated Vu's Charter rights, the Supreme Court ruled the evidence should not be excluded. The Court found the Charter breach wasn't serious because: the law was unclear at the time, police acted in good faith believing they had authority, and the search didn't go beyond what the warrant authorized. The reliable evidence was important for adjudicating serious drug trafficking charges.

Key Takeaway

This decision permanently changed digital privacy rights in Canada — police now need explicit warrant authorization before searching any computer or smartphone.

While this case dealt with Criminal Code charges, the principles apply to all police searches. If you're facing charges where police searched your devices without specific authorization, R. v. Vu may be your strongest Charter argument — though courts will consider whether excluding the evidence would bring the administration of justice into disrepute.
