Controlled Substances and Cannabis Branch: Controlled Substances and Overdose Response Directorate

On this page

About

The Controlled Substances and Overdose Response Directorate administers and monitors compliance with the Controlled Drugs and Substances Act and its regulations. This allows legitimate activities with controlled substances and precursors, while at the same time reducing the risk that such substances will be used for illegal purposes. The directorate also leads the federal Canadian Drugs and Substances Strategy, Canada’s comprehensive and compassionate response to substance-related harms and the overdose crisis.

Responsibilities

The directorate is responsible for:

  • supporting the design and implementation of the Controlled Drugs and Substances Act and its regulations
  • administering and monitoring compliance with the Controlled Drugs and Substances Act and its regulations
  • leading the development, implementation and oversight of the federal Canadian Drugs and Substances Strategy
  • developing strategic advice and recommendations to guide the federal response to the overdose crisis in order to:
    • identify and coordinate collaborative action
    • reduce stigma towards people who use drugs
    • encourage intergovernmental collaboration through bilateral and multilateral engagements
  • providing advice on policy and regulatory direction related to substance use and the overdose crisis supported by a coordinated approach to research, data collection and evidence in collaboration with stakeholders

Directorate and functions

The Office of Legislative and Regulatory Affairs develops legislation, regulations, policy analysis and science-based assessments that support the control of psychoactive substances and precursors under the Controlled Drugs and Substances Act. This office also provides a status confirmation service, a public service that confirms if a substance is controlled in Canada.

Office of Strategic Initiatives and Engagement

The Office of Strategic Initiatives and Engagement is responsible for providing in-depth analysis on the overdose crisis and substance use harms.

Office of Drug Research and Surveillance

The Office of Drug Research and Surveillance is responsible for monitoring trends and patterns related to substance use in Canada, including alcohol, prescription drugs and illegal drug use.
