When FortisBC planned a new natural gas pipeline between Squamish and Coquitlam, British Columbia, the team knew the path forward would require deep, respectful collaboration with Sḵwx̱wú7mesh Úxwumixw (Squamish Nation). That relationship has shaped one of the most important elements of the Eagle Mountain – Woodfibre Gas Pipeline Project: a nine‑kilometre tunnel beneath the Skwelwil’em Squamish Estuary Wildlife Management Area.

For Sḵwx̱wú7mesh Úxwumixw, the estuary is both culturally meaningful and ecologically vital. As condition of regulatory approvals from the BC Environmental Assessment Office and the Nation, the project must utilize an underground trenchless construction method and avoid industrial impacts to the 673-hectare area. Sḵwx̱wú7mesh Úxwumixw is not just an interest holder on the project – they are also a regulator, with the authority to set and enforce its own independent set of conditions.

Engineering with Respect

To meet these conditions, FortisBC developed an innovative approach using two custom‑built tunnel boring machines, each designed for dramatically different subsurface conditions along the route. This solution allows the pipeline to pass deep beneath Monmouth Mountain and the estuary while preserving the land above.

A Shared Path Forward

“What they did was let us lead the way,” says Sḵwx̱wú7mesh Úxwumixw Councillor Wilson Williams.

The tunnel is more than an engineering accomplishment—it represents what’s possible when Indigenous knowledge and industry expertise guide decisions together. Ongoing dialogue between FortisBC and Sḵwx̱wú7mesh Úxwumixw continues to build trust, strengthen understanding and shape how the project moves ahead.

This approach reflects Fortis Inc.’s broader commitment to meaningful, long-term partnerships with Indigenous communities, grounded in respect, shared values, and collaborative project development. In working together—and meeting in the middle—Fortis and its utilities are creating energy infrastructure that honours people, land and future generations.
