Drug Laws

Controlled drugs and substances are governed in Canada by the Controlled Drugs and Substances Act, or the CDSA. The CDSA is federal legislation. It is enforceable anywhere in Canada. It is based on eight schedules. These schedules contain lists of controlled drugs and substances sorted by levels of danger. 

Common Offences


Having in possession means having in personal possession, having in possession or custody of another person or having in any place for their use or benefit. If one person of a group has something in their possession, with the knowledge and consent of other members of the group, every member of the group is deemed to have possession.


Obtaining, or attempting to obtain, the same drugs or prescriptions from more than one doctor. Section 4(2) of the CDSA prohibits double-doctoring.


Traffic means to sell, administer, give, transfer, transport, send or deliver drugs controlled by the CDSA.
