Are records available in both official languages?

The Impact Assessment Agency of Canada respects the Official Languages Act and is committed to ensuring all information and services on the Registry are available in both English and French. However, users should be aware that some information from external sources(such as public comments) are not subject to the Official Languages Act and are made available in the language in which it was provided.

Where can I find information about historical environmental assessments?

Key information about environmental assessments that were completed or terminated under the Canadian Environmental Assessment Act, 1992 (CEAA 1992) is accessible via the Canadian Environmental Assessment Archives. The Archives also contain information about environmental assessments for which a follow - up program may be underway.

CEAA 1992 did not require the maintenance of an online registry prior to October 30, 2003. If you wish to obtain any information regarding these assessments, contact the department or organization that may have had a responsibility to conduct the environmental assessment of the project.

Can I obtain a copy of a record once the assessment is completed?

Requests to access records related to completed assessments should be directed to the department or organization that is identified on the relevant assessment page on the Registry.

How do I submit a comment?

Comments can be submitted via the Registry’s online commenting tool. In order to submit an online comment, users will need to authenticate their identity using one of the approved social media platforms indicated on the login page, such as Twitter, Facebook, Google or Microsoft.

Individuals and organizations are both welcome to submit comments through the online tool. Any user wishing to comment on behalf of an organization should authenticate with that organization’s existing social media account.

To submit a comment, users should log in to the Registry and navigate to the assessment page of interest. The commenting tool can be accessed by clicking “Submit a comment” or “View comments” on the assessment page.

Not all projects on the Registry will have the commenting tool enabled. If the commenting tool is not enabled, participants should refer to the contact information listed on the assessment page.

Why do I need to log in with my social media?

A user’s name and email address associated with the social media platform of their choosing will be used to authenticate their identity. The individual or organization’s name will accompany any submission made and will be posted online. By using a valid social media account, users are bound by the terms of service of that social media platform, and its related policies and rules.

If a participant does not wish to authenticate their identity via a third-party social media platform, they may still submit comments and information via other means. Participants should refer to the contact information listed on the relevant assessment page.

What is done with my online comment?

In order to support more timely access to information and to encourage meaningful participation, information submitted via the Registry is made public in real-time. The responsible federal authority for the assessment you participated in will consider all comments received.

Who do I contact for assistance?
