Canada has approved the Sunrise natural gas pipeline expansion project, a $4 billion development at Enbridge’s Westcoast natural gas pipeline system in British Columbia, marking one of the country’s most significant midstream infrastructure approvals of 2026. The Westcoast natural gas pipeline system expansion project is expected to strengthen domestic gas supply security while expanding export capacity toward growing LNG markets on Canada’s Pacific coast.
Sunrise natural gas pipeline expansion project: What to expect
Enbridge’s Sunrise natural gas pipeline expansion project will increase rate of production on one of Canada’s most important gas corridors, which runs from northeastern British Columbia to the U.S. border.
According to regulatory filings, the project adds new looping segments, compression upgrades, and facility expansions along the existing right-of-way, rather than constructing a completely new pipeline corridor.
Enbridge also says the expansion will support rising demand from residential heating, industrial consumption, and LNG export projects under development in British Columbia.
Project scope and engineering design
Sunrise natural gas pipeline expansion project is primarily a brownfield development, meaning it upgrades and expands existing infrastructure rather than building an entirely new pipeline system.
The project includes approximately 139 kilometers of new pipeline loops, which are parallel segments constructed alongside the existing Westcoast system to increase capacity without significantly altering the corridor footprint. In addition, new compression facilities and modifications to existing stations will improve flow efficiency and pressure management across the system.
Once complete, the project will add around 300 million cubic feet per day (MMcf/d) of incremental capacity to the pipeline system.
The Westcoast pipeline already spans about 2,900 kilometers, making it one of Canada’s key long-haul natural gas transmission systems connecting western production basins to export and domestic demand centers.
The expansion is also expected to improve system reliability during peak winter demand while supporting upstream production growth in the Montney Basin.

Strategic and economic impact of Sunrise natural gas pipeline expansion project
The approval is part of Canada’s plan to position itself as a more diversified energy exporter, particularly to Asia-Pacific LNG markets. Canada has also expanded other oil and gas pipelines in the country with that goal in mind, including the $34 billion Trans-Mountain Pipeline.
Canada’s federal government has also increasingly emphasized the importance of infrastructure corridors that reduce reliance on the United States as the dominant export destination. Recent policy guidelines indicate a shift toward faster permitting of energy projects that align with trade diversification and industrial competitiveness goals.
Economic and upstream capacity impact
Economically, the project is expected to contribute over $3 billion to Canada’s economy and create approximately 2,500 jobs during construction. This will also include significant participation from local and Indigenous communities.
The expansion also aligns with planned LNG developments in British Columbia. These developments require additional upstream pipeline capacity to ensure feed-gas availability. As LNG Canada and other proposed export facilities also ramp up, pipeline bottlenecks have also become a key constraint. Sunrise natural gas pipeline expansion project aims to ease these challenges.
Sunrise natural gas pipeline expansion: Stakeholders and project structure
The project is led by Enbridge Inc., one of North America’s largest midstream operators. Also participating from Indigenous partners include the Stonlasec8 Indigenous Alliance. Stonlasec8 also holds a minority equity stake in the Westcoast pipeline system.
Regulatory oversight is provided by the Canada Energy Regulator (CER). CER also confirmed the project’s alignment with national energy demand forecasts and infrastructure reliability requirements.
The expansion also intersects with provincial energy planning in British Columbia, particularly around LNG export development and grid energy balancing.
