North Montney Mainline


The North Montney Mainline (NMML) Project is in service.

Located in British Columbia’s Peace River Regional District, the NMML provides the critical natural gas transmission infrastructure required to connect natural gas producers and downstream markets throughout Canada and the United States, generating jobs and tax revenues for hospitals, schools and more in some of B.C.’s more remote communities.

The Project consisted of a 206 kilometre (km), 42-inch pipeline, two compressor stations and 11 meter stations. Engagement with local communities, landowners, and Indigenous communities began in 2011 and construction of the Project began in mid-2018 and the facilities were phased into service starting in early 2020.

The first phase to be completed in January 2020 included the 182 km Aitken Creek pipeline section, the Groundbirch compressor station and nine meter stations. The remaining 24 km Kahta pipeline section, the Saturn compressor station and one meter station as part of phase 2 were completed in April/May 2020. The Kobes Meter Station has been constructed and is pending in-service.

Regulatory documents

The North Montney Mainline is part of the NGTL System, which is governed according to regulations outlined by the Canada Energy Regulator (CER), which replaced the National Energy Board (NEB) in August 2019.

Regulatory information

In March 2017, TC Energy filed a variance application, with the NEB,  The Project was originally approved in 2013, subject to conditions making construction contingent on a positive final investment decision on the then proposed PNW LNG liquefication project. NGTL sought approval to remove those conditions through its variance application which included restructured commercial Project arrangements and the associated facilities to accommodate a delay, or as occurred in July 2017, a cancellation of the PNW LNG Project.

In May 2018, the NEB recommended approval of the variance application.

In July 2018, NGTL received Amending Order AO-003-GC-125 (the Order) from the NEB and approved by Governor in Council, approving the variance application and construction of the Project.
