On June 20, 2024, the Budget Implementation Act, 2024, received Royal Assent and brought into force amendments to the Impact Assessment Act (IAA). These changes were made in response to the Supreme Court of Canada's decision on the constitutionality of the IAA. Over the coming weeks and months, this website along with procedures, policy and guidance documents will be updated to reflect these legislative changes, as required.

Impact Assessment Agency of Canada

We promote sustainable development by conducting federal impact assessments of major projects, like mines, ports, and dams. We do this by looking at the environmental, economic, social, and health impacts of these projects and engaging meaningfully with Indigenous Peoples and the public. Learn more about our mandate.
