Environmental Emergency Regulations

These regulations aim to help reduce the frequency and severity of accidental releases of hazardous substances into the environment. Made under the Canadian Environmental Protection Act, 1999 (CEPA), they improve industry’s capacity to deal with environmental emergencies that may occur at fixed facilities across Canada.


These regulations require that any person who owns, has the charge, management or control of a regulated substance at or above certain quantities notify Environment and Climate Change Canada. For higher-risk facilities, an environmental emergency plan must also be prepared, brought into effect and exercised.

The Regulations

The Environmental Emergency Regulations, 2019 (the Regulations) were published in the Canada Gazette on March 6, 2019. They came into force on August 24, 2019.
