Pipeline companies regulated by the CER

The CER regulates companies that own and/or operate interprovincial or international pipelines. For financial regulatory purposes, the companies are divided into two groups:

• Group 1 consists of those pipeline companies with extensive systems and several third-party shippers; and
• Group 2 consists of the remaining pipeline companies that operate smaller, less complex pipelines with few or no third-party shippers.

* The pipelines owned by these companies have been designated under the Canadian Energy Regulator Act as orphan pipelines or orphan abandoned pipelines under s.243 or s.244, respectively, because the company's directors or officers could not be located, or the company is insolvent, bankrupt, or cannot be located. Information on those pipelines can be found on REGDOCs at https://apps.cer-rec.gc.ca/REGDOCS/Item/View/4493624.
