Posted: January 27, 2026

The Tableau tool and all public reports on the AER website will be unavailable on Thursday, February 05, 2026, from 7:00 a.m. to 5:00 p.m. as we perform maintenance on the Tableau server.

If you have questions about the Tableau maintenance outage, contact the Customer Contact Centre by phone at 403-297-8311 ( 1-855-297-8311 toll-free) or by email at inquiries@aer.ca.

The noncompliance and enforcement tab replaces ST108 – AER Monthly Enforcement Action Summary and contains information starting from July 2014.

The responses reported here include the following:

  • enforcement decisions, such as warning letters, administrative penalties, and prosecution;
  • administrative sanctions (e.g., imposition of terms and conditions);
  • directions of an inspector in relation to section 137(2)(c) of the Environmental Protection and Enhancement Act;
  • orders issued to compel compliance or remediate;
  • any notice of noncompliance that is related to a full or partial suspension of operations;
  • suspension or cancellation of an approval; and
  • cancellation of a reclamation certificate.

Compliance orders issued before July 2014 are available under the Index of AER Orders.
