Expert Advisory Group on Safer Supply

On this page


The Expert Advisory Group on Safer Supply provides advice to Health Canada's Controlled Substances and Cannabis Branch about safer supply services in Canada. It is an independent advisory body, created by Health Canada to support Departmental activities pertaining to safer supply service models in Canada.

Safer supply context

The overdose crisis continues to have devastating impacts on individuals, communities and families. The COVID-19 pandemic has worsened long-standing challenges regarding substance use and the overdose crisis, with most jurisdictions reporting record high rates of overdose deaths and harms. In addition, people who use drugs are also facing additional barriers and risks related to the toxicity of the illegal drug supply and reduced access to health and social services.

Safer supply services provide prescribed pharmaceutical-grade alternatives to the toxic illegal drug supply as a way to help prevent overdoses and to connect people to other health and social services.


The Expert Advisory Group began in 2020. Its mandate is to provide Health Canada with independent, expert advice on:
