Detailed Environmental Review

When a proposed project is large or complex in nature, the interactions between the project and the environment are less predictable and identifying the potential adverse effects and appropriate mitigation measures will require careful analysis. For these "medium risk" projects, AANDC will require a detailed environmental review in order to make its decision on whether the project is likely to cause significant adverse environmental effects. Proponents will be referred to the Guide to Completing a Detailed Environmental Review Report, a generic terms of reference document that outlines the informational requirements for this level of review. The terms of reference may be modified to meet the needs of the particular project in question, but the Detailed Environmental Review Report should include the following components:

  • Detailed description of the proposed project and project area;
  • Required regulatory approvals;
  • Any Aboriginal consultation or public engagement activities;
  • Description of the baseline environmental conditions;
  • Identification of potential interactions between each project component and each valued ecosystem component (i.e. an environmental component identified as having scientific, social, cultural, economic or aesthetic value);
  • Proposed mitigation for each interaction between the project and valuable ecosystem component;
  • Analysis of the significance of any residual effects after mitigation is applied; and,
  • Identification of any cumulative impacts

The Detailed Environmental Review Report should be prepared by a qualified environmental professional and submitted to AANDC for review and decision on environmental effects. Please note that as part of its review, AANDC may need to request the input of other federal bodies, such as the Department of Fisheries and Oceans or Environment Canada, for their advice on mitigation, best practices and applicable regulatory authorizations.
