Ongoing environmental assessments (EAs)

On July 6, 2012, the new Canadian Environmental Assessment Act, 2012 (CEAA 2012) came into effect, eliminating the requirements for federal EAs for low-risk projects. On October 24, 2013, the Minister of the Environment finalized amendments to the Regulations Designating Physical Activities (the Project List) identifying those projects that require EAs. The amendment to the regulations does not impact any EAs currently being completed by the Canadian Nuclear Safety Commission (CNSC).

View the Regulations Designating Physical Activities.

To view a specific EA, click on the project title of any EA listed in the table. At the bottom of the EA project page, you will find contact information for the EA specialist responsible for sending you additional information about the EA you are interested in.

EAs that began under the Canadian Environmental Assessment Act have a CEAR number. This reference number links externally to the Canadian Environmental Assessment Registry, which contains information about EAs being conducted by all federal authorities across Canada.

All EAs that started before October 30, 2003 were registered in the Canadian Environmental Assessment Agency's former Federal Environmental Assessment Index (FEAI). Information pertaining to these older EAs is still available on CNSC's site, and can be accessed by clicking on the project title of the EA. Please note that in May 2006 COGEMA Resources Inc. changed its name to AREVA Resources Canada Inc.
