Environmental assessments

The Government of Canada is undertaking a review of environmental and regulatory processes. Visit canada.ca/environmentalreviews to get involved and share your views.

Protecting the environment is an important part of the work at the Canadian Nuclear Safety Commission (CNSC).

The CNSC assesses the environmental effects of all nuclear facilities or activities at every phase of their lifecycle. This assessment is based on the scale and complexity of the environmental risks associated with the facility or activity.

The CNSC carries out EAs under the Canadian Environmental Assessment Act, 2012 (an EA under the CEAA 2012) or under the Nuclear Safety and Control Act (an EA under the NSCA). Early in the process, CNSC staff determine which EA applies by reviewing the information provided by the applicant or licensee in their application and supporting documentation.

The CNSC ensures that the public has an opportunity to participate in the EA, and Aboriginal consultation activities are integrated in the EA process to the extent possible. Learn how you can participate in an EA.

Additional information on the CNSC’s EA process can be found in REGDOC-2.9.1, Environmental Protection: Environmental Policy, Assessments And Protection Measures.
