Impact Assessment Agency of Canada
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 facilitate the sustainable development of major projects subject to the Impact Assessment Act through open and efficient assessments. These assessements identify ways to ensure the environment and Indigenous Rights are protected as projects get built. To support needed investment in major projects, we work closely with other jurisdictions to achieve the goal of “one project, one assessment.” Learn more about our mandate.
