The Canadian Impact Assessment Registry

The Canadian Impact Assessment Registry is equipped with a number of tools to provide users with an interactive experience, including an online engagement platform that makes it easier for Canadians to have a say in projects that concern them.

The Registry facilitates a one-window approach to access information related to the conduct of:

In addition, public access to environmental assessments completed under the Canadian Environmental Assessment Act, 1992 is available via the Canadian Environmental Assessment Archives.

What’s new

March 24, 2021 – The Impact Assessment Agency of Canada launched changes to the Canadian Impact Assessment Registry. Changes include the release of a new Geographic Information System (GIS) mapping tool and a new authentication method to submit comments on the Agency’s online commenting platform.

Authentication for the online commenting tool

  • Previously, users were required to authenticate their identity via an approved social media platform;
  • The Agency has now implemented the Government of Canada standard for Secure Sign-in to provide users with a consistent user experience when accessing government applications;
  • Users will have the option to authenticate their identity using a partner site (e.g. online banking) or using GCKey;
  • Both options are secure and do not transmit any personal or identifying information about the user to the Agency;
  • All users who submit comments using the online commenting tool are subject to the Terms of Use and Submission Policy;
  • For questions related to the new authentication method, refer to the Sign-in Frequently Asked Questions or contact the Agency’s Registry team for assistance.

Interactive GIS mapping tool

  • Access the Agency’s new mapping interface from the Registry homepage by clicking on View Map. It includes interactive tools and advanced functionality to enable users to explore, visualise and analyse assessment data to determine potential impacts near a geographical area of interest;
  • Users can explore assessment information in their community using the “Nearby” tool;
  • The application tools let users import and overlay data layers from various sources to analyze potential impacts to assessments;
  • Users can now export data in multiple formats for further analysis;
  • Maps can be created and printed with the user’s analysis of a specific assessment or area of interest;
  • For technical assistance, refer to the Interactive Assessment Map Quick Reference Guide or contact the Agency’s Geomatics Services team.

Responsible federal authorities

The Agency is the sole responsible authority for impact assessments of designated projects as well as regional and strategic assessments under the Impact Assessment Act. The Impact Assessment Act specifies which records produced, collected or received in support of assessments conducted by the Agency or a review panel are posted online. To ensure a transparent process, the Registry provides online access to a broad range of information that is received and generated throughout the impact assessment of designated projects. This includes information submitted by project proponents, such as detailed project descriptions and comments from the public, stakeholders and Indigenous groups, including advice by expert federal authorities.

The Impact Assessment Act also specifies that other responsible federal authorities manage and maintain records produced, collected or received in support of assessments under their responsibility. Authorities responsible for the conduct of assessments on federal lands or outside Canada include other federal departments and agencies, federal regulators, port and airport authorities, including Crown corporations. Public access to additional records may be obtained by contacting the appropriate federal authority, unless the disclosure of the information is otherwise prohibited under the Access to Information Act and the Privacy Act. In those cases, the Registry includes contact information for each assessment.

New tools and enhanced functionalities

Based on feedback gathered throughout extensive consultations with Canadians and user experience design principles, the Registry now offers new tools and enhanced functionalities in order to:

Find and access information about assessments

Project pages offer easier navigation, including project details, an interactive map, latest updates, nearby projects and key documents.

Key documents to conduct an impact assessment are accessible directly from the project page while all the other documents and comments are available in the section “List all records”.

Improve search capabilities

We have significantly improved the search function to help users find the information they are looking for. The keyword and reference number search offers results listed by relevance. Users are able to customize their search results with filters to help them pinpoint the information for which they are looking.

Users can browse a list of active projects, view assessments on an interactive map or access a list of opportunities where they can get involved.

Give feedback on projects subject to an assessment

The Registry provides users with an easier way to communicate their views with the Agency. It introduces an online commenting tool allowing users to read the comments submitted by others and submit their own from the assessment page.

The ability to provide online feedback on projects is subject to authentication and agreement to the Terms of Use and Submission Policy.

Additional improvements will be implemented through ongoing releases.

If you have questions or require assistance or if you have ideas for future improvements, please contact the Registry team at
