5 takeaways from Enbridge’s $4B Westcoast pipeline expansion

It was a big day for the natural gas industry.

The Canadian Government officially approved the Enbridge’s Sunrise Expansion Program, a $4 billion expansion of Enbridge’s Westcoast pipeline system in B.C. It means thousands of jobs, support for LNG projects and major procurement opportunity.

“The multi-billion dollar Sunrise Expansion Program is a shovel-ready, critical natural gas infrastructure project that supports the advancement of Canada’s energy superpower ambitions,” said Greg Ebel, Enbridge’s CEO and President. “We are thankful for the support of the Canadian Government and other stakeholders who have helped to bring this project to fruition at this critical time for the country. We’re proud of our long history investing and building in Canada and British Columbia, and are excited about the role this project will play in increasing economic prosperity and energy security.”

Now that you’ve heard the news, here’s what you need to know about the project:

1. It’s about adding capacity and supporting major projects

The Sunrise Expansion is designed to add approximately 300 million cubic feet per day of natural gas transportation capacity to the southern portion of the Westcoast pipeline system. Once in service, the added natural gas transportation capacity is expected to strengthen energy security and affordability by supporting access to natural gas during periods of peak demand. Natural gas transported on the Westcoast system is used to heat homes, hospitals, businesses, and schools. It also supports electric power generation, industrial activity across B.C. and global LNG exports. Notably, The expansion will be a strategic backbone for the Woodfibre LNG project near Squamish. As Enbridge holds a 30% stake in Woodfibre LNG, this pipeline expansion is critical to ensuring the facility has the reliable feed gas required to become the world’s first net-zero LNG export terminal.

2. Officials are forecasting major economic impacts

Expected to contribute more than $3 billion to Canada’s economy, Enbridge says the project will involve the hiring of approximately 2,500 workers during construction, including workers from local communities and Indigenous groups in B.C. To date, more than $52 million has been spent on the hiring and procuring of services from Indigenous businesses. Ottawa says it will generate more than $700 million in federal and provincial tax revenue. Enbridge says it will continue to work with Indigenous groups, local communities, contractors and other stakeholders. They have already announced they will be procuring all the pipe from InterPro Pipe + Steel, a Canadian steel mill and pipe provider.

3. It involves 139 km of new pipeline and much more

The project will include the construction of new pipeline segments along the existing system, additional natural gas compression, and upgrades and modifications to existing facilities. The project focuses on increasing natural gas transportation capacity by installing approximately 139 km of 42-inch pipeline loops parallel to Westcoast’s existing right-of-way, alongside infrastructure upgrades at four major compressor stations. Compressor stations give the gas a needed “boost,” helping it
get from one point to the next. To reduce the environmental footprint, electric-driven compressor units will be used, supported by the construction of 10 km of new overhead transmission lines following existing corridors. This integrated approach combines capacity expansion with modern, lower-emission technology to ensure efficient and reliable system operations. Construction is scheduled to begin in July 2026, with a targeted in-service date in late 2028.

4. Westcoast’s roots go back to the 1950s

The Enbridge Westcoast pipeline system, originally known as the Westcoast Transmission Company, was founded by Frank McMahon and began construction in 1955 as Canada’s first “big-inch” natural gas pipeline. Completed in 1957, the initial 1,046 km mainline connected the Peace River region to the U.S. border, marking the birth of British Columbia’s natural gas industry. Throughout the 1960s and 1970s, the system underwent significant expansions, including the extension to Fort Nelson and the addition of major processing plants and gathering lines. Ownership shifted from Westcoast Energy to Duke Energy in 2002, then to Spectra Energy in 2007, before finally being acquired by Enbridge in 2017. Today, The Westcoast system stretches more than 2,900 kilometres from Fort Nelson in northeast B.C. and from Gordondale near the B.C.-Alberta border, south to the Canada-U.S. border at Huntingdon/Sumas. The existing system is ~12.5% owned by the Stonlasec8 Indigenous Alliance Limited Partnership, which represents 38 Indigenous groups in B.C.

5. It’s approved … with conditions

Officials recommended the project’s approval with 47 binding conditions designed to mitigate environmental, technical, and socio-economic risks throughout its lifecycle. These conditions mandate the implementation of updated environmental protection plans , rigorous safety and emergency response exercises , and specific measures to achieve no net loss for caribou habitat, old-growth forests, and wetlands through restoration and offset plans. A significant portion of the requirements focuses on Indigenous participation, including the incorporation of Indigenous knowledge into project design, the establishment of monitoring programs during and after construction, and the provision of regular updates on employment and contracting opportunities for Indigenous Peoples. The bottom line is this: Large contractors will have to show how they are including local Indigenous people and businesses in the work and smaller contractors will need to submit reports highlighting how they are spending dollars with local Indigenous-owned subs.
