Regulatory Information

The Line 3 Replacement Program and the replacement pipeline are regulated by the Canada Energy Regulator (CER), an independent federal agency that acts in the Canadian public interest to promote safety and security, environmental protection and economic efficiency in the regulation of pipelines, energy development and trade. The CER works within a mandate set by Parliament.

On November 5, 2014, Enbridge filed the Line 3 Replacement Program (L3RP) application with the CER's predecessor, the National Energy Board (NEB).

On February 5, 2015, The NEB deemed the L3RP application complete and issued a Notice of Public Hearing and Application to participate.

The oral portion of the National Energy Board’s (NEB) hearings on Enbridge’s proposed Line 3 Replacement Program began on Nov. 30, 2015 in Winnipeg, and concluded on Dec. 14, 2015 in Calgary. The NEB received 16 notices of intent from Indigenous intervenors to provide oral traditional evidence. Filings and transactions pertaining to the project, as well as hearing process updates, can be found on the CER website.

On April 25, 2016, the NEB concluded that the Enbridge Line 3 Replacement Program (Project) is in the Canadian public interest and recommended Project approval to the federal Governor in Council. The Canadian federal government announced its approval of the Line 3 Replacement Program (Project) on Nov. 29, 2016.

Enbridge's L3RP application can be viewed and downloaded directly from the CER's website.
