Ongoing environmental assessments (EAs)

On August 28, 2019, the Government of Canada enacted the Impact Assessment Act (IAA). The IAA broadens the scope of assessments to include environmental, health, social and economic effects – both positive and negative – of a proposed project. It replaces the Canadian Environmental Assessment Act, 2012 (CEAA 2012).

Ongoing projects with environmental assessments (EA), initiated under CEAA 2012 and led by the CNSC, will continue under their current processes. The IAA contains provisions to enable these projects to advance in this way.

To access a specific EA, please click on the project title in the table. At the bottom of the page of the selected EA, you will find the contact information of the specialist who can provide you with further information.
