Practitioner’s Guide to Federal Impact Assessments
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.
The Practitioner’s guide is an evergreen document. Check it periodically, its contents may have been updated because of ongoing engagement and feedback received. If you have feedback, please send it to guidancefeedback-retroactionorientation@iaac-aeic.gc.ca.
