The Supreme Court of Canada has delivered a significant judgment clarifying the scope of legal immunity provided to individuals who call for help during drug overdoses1. In a decision released on October 24, 2025, the nation’s highest court ruled that the Good Samaritan Drug Overdose Act protects individuals not only from being charged with simple drug possession but also from being arrested for that specific offence. The ruling resulted in the acquittal of Paul Eric Wilson, a Saskatchewan man found with firearms after police arrested him for drug possession at the scene of a fentanyl overdose. The court determined that allowing police to arrest individuals for a crime they cannot be charged with would defeat the legislative purpose of saving lives by encouraging people to call 9-1-1 without fear of legal repercussions.
The case originated from an incident on September 10, 2020, in Vanscoy, Saskatchewan. Mr. Wilson was one of four people inside a truck parked near an elementary school. One of the occupants, Cheryl Delorme, suffered a fentanyl overdose, prompting a member of the group to call 9-1-1 for emergency assistance. When the first police officer, Constable Heidi Jo Marshall, arrived at the scene, Ms. Delorme was already receiving treatment from emergency medical services. The officer observed Mr. Wilson and another man lying under the truck, appearing to attempt repairs, while displaying signs of drug impairment. Constable Marshall also noticed a small bag containing a white substance on the ground near the vehicle and detected the smell of marijuana.
Based on these observations, the officer detained the group to investigate for possession of a controlled substance. During this detention, the officer saw Mr. Wilson handling an object in his pocket and observed a streak of white powder appear on the ground near his feet. Constable Marshall subsequently arrested Mr. Wilson and his companions for possession of a controlled substance. Following these arrests, additional officers arrived and conducted a search incident to arrest. This search of the truck and the occupants’ belongings revealed drugs, paraphernalia, and a backpack containing modified handguns and ammunition. Mr. Wilson later admitted the backpack and firearms belonged to him.
While Mr. Wilson was not charged with simple drug possession due to the protections in the Good Samaritan Drug Overdose Act, he was charged with multiple firearms offences and possession of identity documents for fraud. At trial, Mr. Wilson sought to have the evidence of the firearms excluded, arguing that his initial arrest for drug possession was unlawful because the Act prohibited it. He contended that if he could not be charged with the offence, the police had no authority to arrest him for it. The trial judge rejected this argument, convicting Mr. Wilson on most counts and sentencing him to eight years in prison. The Saskatchewan Court of Appeal later overturned this decision, ruling that the arrest was unlawful and excluding the evidence. The Crown then appealed to the Supreme Court of Canada.
The central legal question before the Supreme Court was whether the statutory language, which states that no person who seeks emergency assistance is to be “charged or convicted” of simple possession, implies an immunity from arrest. The Crown argued that the text of the law was clear and unambiguous. They contended that Parliament deliberately omitted the word “arrest” from the legislation to allow police to maintain public safety and secure crime scenes. The Crown suggested that while a person could not be formally charged, the power to arrest was a necessary investigative tool to remove drugs from the street and prevent further crimes.
Writing for the majority, Justice Karakatsanis dismissed the Crown’s appeal and upheld the acquittal. The majority opinion emphasized that statutory interpretation requires looking beyond the strict definition of individual words to understand the purpose and context of the legislation. The court noted that the Good Samaritan Drug Overdose Act was enacted in 2017 to address a national public health crisis. Parliament’s explicit goal was to remove the fear of legal consequences that often causes bystanders to hesitate before calling 9-1-1 during an overdose.
The majority reasoned that an arrest is a significant deprivation of liberty that carries severe consequences, including the power of police to conduct invasive searches. If individuals at the scene of an overdose know they can still be arrested, handcuffed, and searched, they will remain afraid to call for help, even if they know they cannot be formally charged later. Justice Karakatsanis wrote that the threat of arrest and the subsequent searches would substantially undermine the life-saving purpose of the Act. The court concluded that immunity from arrest is a necessary implication of the immunity from charge and conviction.
The court also rejected the argument that police need the power to arrest for simple possession to investigate other crimes. The majority stated that Canadian law does not permit arrests to be used solely for investigative purposes where there are no reasonable grounds to believe a different offence has been committed. Using an arrest for an immune offence as a pretext to search for other evidence would expand police powers in a way Parliament did not intend. The judgment clarified that police still retain other powers to ensure safety at overdose scenes. Officers can seize drugs in plain view, detain individuals if reasonably necessary for safety, and arrest for other offences if independent grounds exist. However, they cannot arrest someone solely for simple possession when that person is protected by the Good Samaritan immunity.
Because Mr. Wilson was protected from being charged with simple possession, his arrest for that offence was unlawful. Consequently, the search of the truck that followed the arrest violated his Charter right to be secure against unreasonable search and seizure. The majority ruled that the breach of rights was serious enough to warrant the exclusion of the firearm evidence found during the search. Without that evidence, there was no case against Mr. Wilson, and his acquittal was restored.
Three judges dissented from the majority decision. Justice Jamal, writing for the dissent, argued that the text of the legislation was precise and that “charged” and “convicted” are distinct legal terms that do not include “arrest.” The dissenting judges expressed concern that the majority’s interpretation ignored the public safety objectives of the Controlled Drugs and Substances Act. They argued that Parliament intended to balance public health with public safety, not to pursue public health at the expense of all other considerations.
The dissenting opinion highlighted the practical difficulties police officers face in rapidly evolving situations. They noted that officers at the scene of an overdose must make split-second decisions to protect the public, particularly in sensitive locations like the schoolyard where this incident took place. The dissent argued that removing the power to arrest for simple possession would leave officers uncertain about their authority to detain suspects or control a scene where illegal drugs are present. They pointed to legislative debates where assurances were given that the Act would not limit police powers or prevent investigations.
Despite these objections, the majority ruling stands as the law of the land. The decision establishes that when evidence of simple drug possession is discovered because a person called 9-1-1 for a medical emergency, or remained at the scene to help, that person cannot be arrested for possession. This immunity applies to the specific offence of simple possession but does not extend to other crimes such as trafficking or weapons offences if independent evidence exists.
The Supreme Court’s judgment ultimately turned on the conclusion that the law’s primary intent was saving lives. The court determined that achieving this goal requires a clear rule that the public can understand: if you call for help during an overdose, you will not be arrested for the drugs found at the scene. By excluding the evidence obtained through the unlawful arrest of Mr. Wilson, the court reinforced the principle that police powers must be exercised within the specific limits set by Parliament to protect civil liberties and public health initiatives. Paul Eric Wilson’s acquittal on all charges is now final.
