North Corridor Expansion Project


The North Corridor Expansion Project is now in service. Located in northwestern Alberta, the Project expanded pipeline capacity on the NOVA Gas Transmission Ltd. (NGTL) System for the transportation of natural gas from the Peace River Project Area to growing markets located in northeastern Alberta. The project included:

The North Central Corridor (NCC) Loop - North Star Section 2, a 48-inch, 24 kilometre (km) pipeline located approximately 20 km north of Manning, Alberta in Northern Lights County.

The NCC Loop - Red Earth Section 3, a 48-inch, 32 km pipeline located approximately 45 km north of Red Earth Creek, Alberta in Northern Lights County and the MD of Opportunity.

The Northwest Mainline Loop No. 2 - Bear Canyon North Extension Section, a 36-inch, 25 km pipeline located 50 km southwest of Worsley, Alberta in Clear Hills County.

NGTL also constructed a 30-megawatt unit addition at the existing Hidden Lake North Compressor Station, approximately 100 km north of Worsley, Alberta in Clear Hills County.

NGTL filed an application with the National Energy Board (NEB), predecessor to the Canada Energy Regulator (CER), for the Project on April 4, 2019. The CER issued Certificate GC-131 and Order XG-021-2020 approving the Project in May and June 2021, respectively.

The North Corridor Expansion Project was part of TC Energy’s $1.5 billion expansion to the NGTL System to connect Western Canadian Sedimentary Basin supply to incremental market demand. Read more.

Project benefits

Projects deliver well-designed and constructed infrastructure that provides short-term and long-term economic benefits and strengthens the economy on a local, provincial and national level.

Employment opportunities — Construction requires the services of equipment operators, welders, mechanics, truck drivers, labourers and more.

Business opportunities — Pipeline construction creates demand for local goods and services, including food and accommodation, hardware, industrial parts, automotive parts and servicing, fuel and more.

Annual revenue to support local services — Project construction results in tax payments to municipal, provincial and federal governments. Now operational, the Project provides annual tax payments that will help support schools and hospitals, emergency services, recreation facilities, recycling programs and other local programs vital to sustaining communities.

Investments in local communities — Through our engagement with local communities, we identify areas where we can help build stronger, more vibrant communities through initiatives with community partnerships in the areas of safety, community and environment.
