Enbridge $2.9B BC gas pipeline expansion: design, capacity and schedule notes for engineers

30 Second Briefing
Enbridge’s C$4 billion Sunrise Expansion Program has secured Canadian federal approval to add about 300 million cubic feet per day of capacity to the southern portion of the Westcoast natural gas pipeline system in British Columbia. The project will build new pipeline segments parallel to existing corridors, install additional compression, and upgrade current facilities, with construction slated from July 2026 to a late‑2028 in‑service date. Enbridge expects over C$3 billion in economic contribution, around 2,500 construction jobs, and has already directed C$52 million to Indigenous businesses.
Technical Brief
- Capital cost is C$4 billion, framed by Enbridge as a “multi‑billion dollar” shovel‑ready project.
- Sunrise Expansion is on the southern portion of Enbridge’s Westcoast natural gas transmission system in British Columbia.
- 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.
- Federal approval confirms the project meets “rigorous environmental and safety standards”, a key permitting constraint for routing and construction.
- Enbridge reports more than C$52 million already contracted to Indigenous businesses for services and labour.
- Construction workforce is projected at ~2,500 jobs, explicitly including local and Indigenous hiring targets.
- Natural gas throughput is intended to support domestic heating, industrial loads and feedstock for global LNG exports from BC.
- Federal positioning of Sunrise as “critical natural gas infrastructure” signals continued policy support for large‑scale gas transmission projects in Canada.
Our Take
Within our 817 Infrastructure stories, very few involve British Columbia natural gas assets of the scale of Enbridge’s Westcoast system, signalling that this expansion will likely be a reference case for future federal reviews of large-capacity gas corridors in western Canada.
The timing of this natural gas expansion alongside April 2026 coverage of magnesium and broader critical minerals projects indicates Canada is pursuing parallel infrastructure tracks—gas for near- to mid-term energy security while critical minerals like magnesium are positioned for longer-horizon decarbonisation supply chains.
