The Glossary of Terms for the impact assessment of designated projects under the Impact Assessment Act (the Act) is for information purposes only. It is not a substitute for the Act or any of its regulations. In the event of any inconsistency between this guide and the Act or regulations, the Act or regulations would prevail.
For the most up-to-date versions of the Act and regulations, please consult the Department of Justice website.
This document may be reviewed and updated periodically by the Impact Assessment Agency of Canada (the Agency).
Purpose of the Glossary
