R v Barnes

[1991] 1 SCR 449

Supreme Court of Canada 28 February 1991 drug trafficking

R. v. Barnes

[1991] 1 S.C.R. 449
Supreme Court of Canada — Lamer C.J. and Wilson, La Forest, L'Heureux-Dubé, Sopinka, Gonthier, Cory, McLachlin and Stevenson JJ. | February 28, 1991


Background

Philip Barnes was walking near Vancouver's Granville Mall when an undercover police officer approached him during a 'buy-and-bust' operation. The officer later testified she picked Barnes based on 'a hunch' — he was 'dressed scruffy' with long hair, fitting her 'general criteria' for someone who might sell drugs. When she asked if he had any 'weed,' Barnes initially said no twice. After the officer persisted, Barnes eventually sold her a small amount of cannabis resin for $15.

Barnes was convicted of trafficking cannabis resin, possession for the purpose of trafficking, and possession of marijuana. However, the trial judge found the police had engaged in 'random virtue testing' and granted a stay for entrapment. The BC Court of Appeal overturned this, ordering a new trial instead of entering convictions.

Issues

  1. Did the police officer engage in random virtue-testing that constituted entrapment?
  2. Did the Supreme Court have jurisdiction to enter convictions without a Crown cross-appeal?

The Entrapment Test

The Supreme Court clarified the test from R. v. Mack: entrapment occurs when police provide an opportunity to commit an offence without reasonable suspicion that the person is already engaged in criminal activity or without conducting a bona fide inquiry. The Court found that while the officer had no reasonable suspicion about Barnes individually (his appearance wasn't enough), she was conducting a legitimate investigation in an area where drug trafficking was known to occur.

The Court emphasized that when police conduct a bona fide investigation in a location where criminal activity is reasonably suspected, they can present opportunities to any person in that area — even randomly. The Granville Mall was a legitimate target area with documented drug trafficking, making this permissible within a proper investigation rather than random virtue-testing.

Jurisdictional Issue

The Court ruled it had no jurisdiction to enter convictions because the Crown hadn't cross-appealed the Court of Appeal's order for a new trial. Under the Criminal Code's appeal provisions, when there's no Crown appeal, an accused cannot leave the Supreme Court with less than what they gained from the lower court. This preserved the new trial order despite finding no entrapment occurred.

Key Takeaway

Police can approach people randomly during undercover operations if they're investigating a specific area where crime is known to occur — your appearance alone doesn't need to create reasonable suspicion.

This case shows that entrapment defenses are difficult when police can point to legitimate area-based investigations, even if their target selection seems arbitrary or based on stereotypes.

R v Clothier

2011 ONCA 27

Ontario Court of Appeal 13 January 2011 selling tobacco to a minor

R. v. Clothier

2011 ONCA 27
Court of Appeal for Ontario — Laskin J.A. (O'Connor A.C.J.O., Gillese J.A. concurring) | January 13, 2011


Background

Matthew Clothier was a 19-year-old clerk working at a 7-Eleven in Sarnia when the Tobacco Enforcement Office of Lambton County sent a 17-year-old "test shopper" to his store. The teen asked for a package of Peter Jackson cigarettes, and Clothier sold them to her without asking for ID — the whole transaction took about 35 seconds. An enforcement officer then entered the store, informed Clothier he'd sold tobacco to a minor, and issued him a certificate of offence under section 3(1) of the Smoke Free Ontario Act.

The store had been randomly chosen from a master list of tobacco vendors in the county. The authorities had no reason to suspect Clothier or the 7-Eleven had previously sold tobacco to minors — this was purely a random compliance check. Clothier had been properly trained on age verification procedures and had no prior convictions.

Issues

  1. Does the defence of entrapment apply to regulatory offences under the Smoke Free Ontario Act?
  2. Can government authorities use random test shopping to monitor compliance without reasonable suspicion of illegal activity?

The Entrapment Defence and Regulatory Offences

Clothier argued entrapment — that the authorities couldn't offer him an opportunity to commit an offence without reasonable suspicion he was already breaking the law. In criminal cases, this defence protects against "random virtue testing" that would invade personal privacy and potentially lead law-abiding people into criminal activity.

The Court of Appeal disagreed, drawing a crucial distinction between criminal law and regulatory offences. Justice Laskin explained that stores selling tobacco operate in a regulated commercial environment where they've accepted responsibility to the public. This comes with consequences: a greatly diminished expectation of privacy and acceptance that monitoring will be necessary to ensure compliance.

The court identified three key differences from criminal entrapment: First, this isn't "virtue testing" but "compliance testing" — section 3(1) is a strict liability offence where negligence alone can lead to conviction. Second, the test shopping happens at a store that sells tobacco as part of ordinary business, so the opportunity to commit an offence when the teen asks for cigarettes is no different from any underage customer making the same request. Third, those who choose to participate in regulated activities must accept the consequences of that responsibility.

Key Takeaway

Random compliance checks are legal for regulatory offences — but they must be done in good faith.

Government authorities can conduct random test shopping without reasonable suspicion, but courts retain jurisdiction to stay proceedings if the testing is done discriminatorily or for improper purposes. The broader abuse of process doctrine still protects against government conduct that offends decency and fair play.

R v Jewitt

[1985] 2 SCR 128

Supreme Court of Canada 19 September 1985 trafficking in narcotics

R. v. Jewitt

[1985] 2 S.C.R. 128
Supreme Court of Canada — Dickson C.J. and Beetz, McIntyre, Chouinard, Lamer, Wilson and Le Dain JJ. | September 19, 1985


Background

Damon Fidel Garfield Jewitt was charged with unlawfully trafficking in cannabis (marijuana) under the Narcotic Control Act. At his trial in Vancouver, he pleaded not guilty but admitted selling one pound of marijuana to what he thought was a fellow employee — who turned out to be an undercover police officer.

The jury found there had been unlawful entrapment by police. Based on this finding, the trial judge directed the Clerk of the Court to make an entry staying the proceedings on the indictment. The Attorney General of Canada appealed this "acquittal" to the British Columbia Court of Appeal, which dismissed the Crown's appeal for want of jurisdiction — they said the Crown had no right to appeal a stay of proceedings.

Issues

  1. Does a trial court judge have discretionary power to stay proceedings in a criminal case for abuse of process?
  2. Is a judicially-entered stay of proceedings equivalent to a "judgment or verdict of acquittal" that can be appealed by the Crown under s. 605(1)(a) of the Criminal Code?

The Power to Stay for Abuse of Process

The Supreme Court confirmed that trial judges do have residual discretion to stay proceedings where compelling an accused to stand trial would violate fundamental principles of justice and prevent abuse of the court's process through oppressive or vexatious proceedings. This power stems from the court's inherent jurisdiction, recognized in Canada as early as 1886. However, the Court emphasized this is a power of "special application which can be exercised only in the clearest of cases" — it should only be used in the most exceptional circumstances.

Stay of Proceedings vs. Acquittal

The Court's main ruling addressed whether a stay equals an acquittal for appeal purposes. The judges examined the purpose and effect of each: a stay of proceedings stops or arrests judicial proceedings by court direction, while an acquittal is a final determination that the accused is not guilty. Although both effectively end the proceedings and prevent the accused from being tried again on the same charge, the Court concluded they are legally different. A stay is based on procedural considerations and questions of law, while an acquittal determines guilt or innocence on the merits. Since s. 605(1)(a) of the Criminal Code allows Crown appeals from "judgment or verdict of acquittal," and Parliament used specific language, the Court held that a stay of proceedings is tantamount to an acquittal and therefore subject to Crown appeal.

Key Takeaway

When a judge stays proceedings for abuse of process, it's legally equivalent to an acquittal — meaning the Crown can appeal it.

This case clarifies that while trial judges have power to stay proceedings in exceptional circumstances involving serious procedural abuse, such decisions aren't immune from Crown appeals. The ruling ensures that the abuse of process doctrine can't be used as an end-run around the normal appeal process.

R v Mack

[1988] 2 SCR 903

Supreme Court of Canada 15 December 1988 drug trafficking

R. v. Mack

[1988] 2 S.C.R. 903
Supreme Court of Canada — Lamer J. | December 15, 1988


Background

Norman Lee Mack was a former drug addict who had given up narcotics and was trying to develop property near De Roche, British Columbia. In 1979, he met Momotiuk (a police informant) through a mutual friend in Montreal. Over six months, Momotiuk persistently tried to get Mack involved in drug trafficking, claiming he represented a large syndicate that needed suppliers.

Mack repeatedly refused these requests. The situation escalated when Momotiuk took Mack for a walk in the woods, produced a pistol, and made veiled threats saying "a person could get lost." When Mack continued to refuse, he was told to "get his act together." Eventually, after being shown $50,000 in cash and facing continued pressure, Mack obtained cocaine from a supplier (who agreed to help "get Doug off me") and was arrested during the delivery.

Issues

  1. What constitutes entrapment under Canadian law?
  2. Should entrapment be decided by a judge or jury?
  3. What is the burden of proof for entrapment claims?

The Supreme Court's Definition of Entrapment

The Court established that entrapment occurs in two situations: (a) when authorities provide an opportunity to commit an offense without reasonable suspicion that the person is already engaged in criminal activity or without a bona fide inquiry, or (b) when authorities go beyond providing an opportunity and actually induce the commission of an offense.

Critically, the Court ruled that entrapment should be assessed objectively — not based on the accused's state of mind or predisposition, but on whether the police conduct would likely induce an average person to commit the crime. The Court rejected the American "subjective" approach that focuses on whether the accused was predisposed to commit the offense.

The Court outlined several factors to consider: the type of crime, whether an average person would be induced, the persistence of police attempts, the type of inducements used (threats, fraud, exploitation of vulnerabilities), the timing of police involvement, and whether the conduct undermines constitutional values.

Procedural Rules

The Supreme Court ruled that entrapment claims must be decided by the trial judge (not a jury) because they involve questions of law and policy about acceptable police conduct. The accused bears the burden of proving entrapment on a balance of probabilities. If entrapment is proven, the remedy is a stay of proceedings — not an acquittal — because the accused did commit the offense, but the state's conduct makes prosecution an abuse of process.

Key Takeaway

Police cannot use threats, persistent pressure over months, and psychological manipulation to induce someone to commit a crime, even if that person has a criminal history.

The Court found that Mack's case involved clear entrapment due to the threats, the six-month campaign of pressure, and the informant's escalating tactics when faced with repeated refusals. This landmark decision protects individuals from overzealous police tactics that go beyond legitimate law enforcement.

R v Scott

[1990] 3 SCR 979

Supreme Court of Canada 13 December 1990 trafficking in a narcotic

R. v. Scott

[1990] 3 S.C.R. 979
Supreme Court of Canada — Cory J. (majority), McLachlin J. (dissenting) | December 13, 1990


Background

Winston Scott was charged with trafficking cocaine after undercover officer Ronald Wretham conducted a five-month investigation. The case started when Scott approached Wretham at Winston Ross's auto body shop, leading to multiple drug sales. During Scott's first trial, defense counsel tried to cross-examine the investigating officer about why Ross had been arrested the same day as Scott — a question that would have revealed the identity of a police informer.

When the trial judge indicated he would allow the questioning despite Crown objections, Crown counsel immediately stayed the proceedings under s. 508(1) of the Criminal Code to protect the informer's identity. The Crown then re-instituted the proceedings under s. 508(2) before a different judge, who refused to allow the same line of questioning and ultimately convicted Scott.

Issues

  1. Did the Crown's decision to stay proceedings and restart before a new judge constitute an abuse of process?
  2. Was Scott denied his right to make full answer and defence when refused the opportunity to question the informer's identity and call witness Ross on entrapment?

The Abuse of Process Finding

Four justices found clear abuse of process. McLachlin J.'s dissenting reasons (joined by Lamer C.J. and La Forest J.) emphasized that using s. 508 to circumvent unfavorable rulings creates systemic problems: it gives the Crown an advantage unavailable to accused persons, amounts to "judge-shopping," and undermines the integrity of the judicial process. The Crown had alternatives — they could have declined to call further evidence and appealed any resulting acquittal, as happened successfully in R. v. Banas and Haverkamp.

The majority disagreed, finding the Crown acted properly to protect informer identity — a recognized public interest. Cory J. emphasized the Crown acted in good faith and that Scott suffered no prejudice since he remained in custody on other matters. However, the case reveals a fundamental tension between prosecutorial discretion and fairness in the justice system.

The Entrapment Evidence Issue

A separate issue emerged when witness Ross appeared during final submissions but the trial judge refused to hear his evidence on entrapment. Following R. v. Mack, entrapment is determined separately from guilt or innocence — after conviction, not during trial. McLachlin J. found error here: since Ross's evidence related to entrapment (a post-conviction issue), not guilt, the judge should have allowed it. There was evidence connecting Ross to the transactions that could support an entrapment argument.

Key Takeaway

Crown prosecutors cannot use stays of proceedings as a "do-over" mechanism when they receive unfavorable rulings.

While this Supreme Court case involved serious criminal charges, the principle applies to all prosecutions: the proper remedy for adverse judicial rulings is appeal, not procedural manipulation. The case also demonstrates that evidence relevant to distinct legal issues (like entrapment) may be heard at appropriate times, even after the main trial concludes.
