Controlled Drugs and Substances Act
The Controlled Drugs and Substances Act (CDSA) is Canada’s primary legislation regulating narcotics, controlled substances, and precursor chemicals. The Act classifies substances into schedules (I to VIII) based on their potential for abuse and medical utility. It creates offences for possession, trafficking, production, import, and export of controlled substances. Penalties vary by substance schedule and offence type, ranging from summary conviction for simple possession to life imprisonment for trafficking in Schedule I substances (heroin, cocaine). The Act also provides for search warrants, forfeiture, and the medical exemption framework. The Act has been profoundly affected by cannabis legalization under the Cannabis Act (2018).
Legal area: Criminal law defines offences against the state and society, establishes penalties, and governs sentencing and corrections.
Year enacted: 1996

Significance
The CDSA is central to Canada’s drug policy and enforcement framework. The Act’s medical exemption (section 56) was the basis for the medical cannabis program, which preceded full legalization. The Supreme Court has addressed the CDSA in landmark cases including R v Malmo-Levine (2003) on the constitutionality of cannabis prohibition, R v Smith (2015) on medical marijuana access, and Canada (AG) v PHS Community Services Society (2011) on Insite supervised injection site. The Act has been amended to modernize enforcement and address the opioid crisis.
