2021–22 Annual Report of the Commission of the Canada Energy Regulator – Appendix E: Commission Orders and Directions 2021–22

The following table summarizes Commission of the Canada Energy Regulator (the Commission) Orders (sometimes referred to as Safety Orders) and Directions that were active in 2021–22. The Commission can issue these Orders pursuant to section 95 of the Canadian Energy Regulator Act, to ensure the safety and security of persons and facilities and/or for the protection of property or the environment. Previously, the National Energy Board issued these Orders pursuant to section 48 of the National Energy Board Act.

Many Orders will remain in effect for several years, in which case CER staff will continue to monitor compliance with the Order. The existence of a Safety Order in many cases establishes/imposes safe thresholds for continued operation (e.g., pressure restrictions). It is necessary to keep these restrictions in place until such time as the Commission is of the opinion that the company has sufficiently addressed underlying issues.
