Types of Environmental Assessments

Under the Canadian Environmental Assessment
Act
(CEAA), there are three types of Environmental Assessments that can be undertaken: screenings, comprehensive studies and review panels. Panels can also be subject to mediation if there are unresolved issues related to environmental effects or public concerns.

The vast majority of CEAA assessments are screenings. While the term "screening" may suggest a cursory review, screenings involve the systematic assessment of environmental effects and mitigation measures in order for a responsible authority to make a decision on the significance of environmental effects and whether or not to take action in support of the project.

All projects are subject to a screening unless they are identified on the Comprehensive Study List Regulations. Projects on the Comprehensive Study List Regulations are typically large-scale undertakings and for this reason a more intensive assessment is required.
