Regional and strategic assessments

The Impact Assessment Act allows for the conduct of regional and strategic assessments. These may happen in one of two ways. The Minister of Environment and Climate Change may establish a committee for one of these assessments or the Minister may authorize the Impact Assessment Agency of Canada to conduct the assessment. Regional and strategic assessments are considered in federal impact assessments. They may have various other outcomes, depending on the specific regional or strategic assessment.

Regional assessments assess the positive and adverse effects of multiple existing and future physical activities in a specific geographic region, including cumulative effects.

Strategic assessments examine the Government of Canada's existing or proposed policies, plans, or programs relevant to impact assessment. Strategic assessments may also focus on issues relevant to impact assessment.

Information on potential, ongoing and completed regional and strategic assessments is available on the Canadian Impact Assessment Registry.

The Agency has developed the following policy and guidance documents to support the conduct of regional and strategic assessments under the Impact Assessment Act. This page will be updated as further policy and guidance become available.

• Policy Framework on Strategic Assessment under the Impact Assessment Act
• Fact sheet: Strategic Assessment under the Impact Assessment Act
