Enbridge Breaks Ground on $4B Sunrise Gas Pipeline Expansion in B.C.
Enbridge has broken ground on its $4-billion Sunrise Expansion Program in British Columbia, according to a Canadian Press report via BOE Report, kicking off a major buildout of the province’s natural gas transmission system near Prince George.
Market Impact
The federal government approved the Sunrise project in April, clearing the way for Enbridge to add roughly 300 million cubic feet per day of transportation capacity to its existing 2,900-kilometre Westcoast Pipeline. The expansion calls for about 140 kilometres of new pipe across 11 looping segments built parallel to the existing line, plus compression and other upgrades to boost throughput. Ottawa says the added capacity will help supply LNG export terminals on the West Coast while covering local demand. Enbridge holds a 30% stake in the Woodfibre LNG terminal under construction in Squamish, B.C., giving the company a direct stake in moving more gas west.
The project is using Canadian melted and poured steel from InterPro Pipe and Steel in Saskatchewan, a detail that signals domestic mills are already seeing order volume tied to the build. Ownership of the underlying pipeline system also includes a 12.5% stake held by an alliance of 28 Indigenous communities in B.C., who acquired their share of the existing Westcoast line last year. Enbridge has said those groups aren’t required to take equity in the expansion itself but have the option to do so.
What It Means for Subcontractors
- Civil and pipeline crews: With 11 looping segments and 140 kilometres of new pipe planned along the Westcoast corridor near Prince George, expect multiple bid packages for clearing, grading, trenching, and pipe-laying work to roll out as Enbridge sequences construction along the route.
- Welding and pipefitting shops: Steel sourced from InterPro Pipe and Steel in Saskatchewan is already moving, meaning weld-out and tie-in crews should position now for compression station upgrades and looping segment tie-ins rather than wait for a formal subcontract announcement.
- Mechanical and E&I trades: The project includes compression and throughput upgrades beyond the new pipe itself, opening separate scopes for mechanical installation and electrical/instrumentation work at compressor sites along the 2,900-kilometre system.
- Local labor and camps: Northern B.C. contractors near Prince George should expect workforce housing, camp services, and logistics demand to ramp alongside construction crews mobilizing for a multi-year, $4-billion build.
- Indigenous-owned firms: With 28 Indigenous communities holding a 12.5% stake in the existing Westcoast line and an option to invest in the expansion, Indigenous-owned contractors and joint ventures may find added weight in procurement decisions tied to this project.
