2021 NGTL System Expansion

October 20, 2020 update

TC Energy received approval from the Government of Canada for its 2021 NGTL System Expansion Project and is awaiting the details of the updated conditions to be released. For more information on the approval, please visit the Natural Resources Canada website.

NGTL expects that this approval will allow it to immediately progress construction activities in accordance with regulatory requirements, with compressor station field work expected to begin in December 2020 and pipeline construction activities expected to start in January 2021.

For more information, please view our media advisory.


September 8, 2020 update

As a Governor in Council (GIC) decision has not been issued yet, construction did not begin in summer 2020 as originally planned and the critical winter construction season has been substantially reduced.

In anticipation of GIC approval, we continue to refine the project’s construction schedule and advance construction planning.

We remain committed to the project and continue to engage with the government to advocate the criticality of a timely approval to enable us to construct to provide the essential capacity required to serve incremental transportation contracts and meet the growing demand for natural gas sourced from the Western Canadian Sedimentary Basin (WCSB).


May 19, 2020 GIC decision delay

On May 19, 2020, we received notice that the Governor in Council (GIC) has extended the timeline by up to 150 days for a decision regarding the Certificate of Public Convenience and Necessity (CPCN) for the 2021 NOVA Gas Transmission Ltd. (NGTL) Expansion Project. While this news is disappointing, we understand that the delay was associated with the government’s consultations being impacted by COVID-19. We are developing mitigation plans to reduce the impacts stemming from this delay. Depending when a decision is received, we will communicate the anticipated outcomes of this updated schedule once they are known.

For more information, please visit the Natural Resources Canada website.

Natural Gas Icon



The Western Canadian Sedimentary Basin (WCSB) is one of North America’s most prolific natural gas production basins, and it is of key importance to the Canadian economy.

Given the production of natural gas in Alberta and B.C., the most important issue for WCSB producers is getting their product into other markets. To be competitive, access to markets through well-positioned pipeline assets is critical.

Natural gas producers have asked us to increase natural gas transportation service on the NGTL System. As a result, we are beginning to plan a pipeline expansion project in northwest Alberta that will run along the west path of the NGTL System, from the northwest Alberta southeast towards Rocky Mountain House.

We are currently studying options for a number of pipeline additions that will generally follow our existing NGTL pipeline corridors in western Alberta. In total, NGTL is proposing to add up to approximately 350 kms (214 miles) of newly built 48-inch pipe to the NGTL System.

These various pipeline sections within the study area would be located starting in the County of Grande Prairie, extending through the Municipal District of Greenview No. 16, Yellowhead County, and ending in Clearwater County. Multiple pipeline sections would run parallel to the existing system and connect at each end to adjacent existing pipelines.

The routes we’re investigating are subject to change and would add multiple pipeline sections and compressor station unit additions to our existing assets in three key areas:

  • Grande Prairie West Area
  • Grande Prairie South Area
  • Edson South Area.

What to expect during construction

NGTL engages the community frequently during the construction planning and execution of our projects. We engage interested chambers of commerce, business community members and Indigenous-owned businesses to provide information about our construction plans.

We encourage all local vendors interested in the opportunities created by the Project visit our Vendors page for more information on how to connect your business with ours.


Documents and maps

The pipeline additions will generally follow our existing NGTL pipeline corridors in western Alberta. The routes we’ve chosen would add multiple pipeline sections to our existing assets along our Grande Prairie Mainline and Edson Mainline pipeline assets.

Regulatory documents

How are we regulated?

The 2021 NGTL System Expansion Project is governed according to regulations outlined by the Canada Energy Regulator (CER), which replaced the National Energy Board (NEB) on August 28, 2019. For more information about the CER web site.

Project Application

NOVA Gas Transmission Ltd. (NGTL) submitted an application to the Canada Energy Regulator (CER) seeking approval to construct the 2021 NGTL System Expansion Project (the Project). The CER has assessed the application and has issued their report and conditions of approval for consideration by the Federal Government. When the CER’s report is assessed, the government will consider the consultation and feedback received from stakeholders, landowners, and Indigenous groups in making their final decision on whether to issue a certificate of public convenience and necessity (CPCN) and authorizing the CER to proceed with an approval.
