Eagle Mountain - Woodfibre Gas Pipeline Project
As a utility, meeting the energy needs of our customers is what FortisBC does every day.
That’s why when our customer Woodfibre LNG asked us if we could deliver natural gas to them, we began to explore how. Now, after years of talking to the community and rigorous environmental protection planning, construction has started on the Eagle Mountain – Woodfibre Gas Pipeline (EGP) Project.
Project overview
The project will expand a portion of our existing natural gas transmission system, which was built in 1991 to serve Squamish, the Sunshine Coast and Vancouver Island.
It involves adding 50 kilometres of new gas pipeline between Coquitlam and Squamish. This includes 47 kilometres of new 24-inch gas pipeline from north of Coquitlam to the Woodfibre LNG site, and an additional three kilometres of pipe near Westwood Plateau in north Coquitlam. The majority of this line will run alongside our existing pipeline to minimize environmental footprint.
A key component of the project is the construction of a 9-kilometre tunnel under the Squamish Estuary to limit environmental impacts.
The route

Generally, the new gas pipeline will follow the existing gas pipeline route to limit new impacts to the environment along the route.
In some cases, following the existing route entirely will not be possible. Throughout project planning we've worked to minimize impacts and respond to feedback. Examples include:
- achieving the shortest possible route and the smallest overall footprint
- minimizing crossings of streams and rivers
- incorporating Indigenous, landowner and stakeholder input
- avoiding known archaeological or heritage sites
- avoiding sensitive terrain and environmental areas
Compressor stations
Compressor stations are one of the most important components of the natural gas transportation system. They perform the essential tasks of compressing the natural gas and regulating its pressure so it can flow through the system to our customers’ homes and businesses.
To provide service to Woodfibre LNG, we considered a number of factors, including feedback from the public, the District of Squamish and Skwxwú7mesh Úxwumixw (Squamish Nation) during the environmental assessment processes. We’ll continue to listen and respond as we move forward.
Rigorous environmental reviews and research
For nearly ten years, we’ve been meeting with local residents, Indigenous groups, stakeholders, local government and the regulators to gather and incorporate feedback into various aspects of our environmental assessment.
On June 24, 2016, Skwxwú7mesh Úxwumixw Chiefs and Council voted to approve the project. On August 9, 2016, the provincial government issued an Environmental Assessment Certificate for the project.
Project changes approved
Since then, a number of project changes were proposed to reflect community feedback and technical advancements identified during detailed design. In fall 2021, the BC Environmental Assessment Office (EAO) approved these changes, followed by Skwxwú7mesh Úxwumixw’s approval in early 2022 as part of a harmonized review process with the EAO. These approvals amended both the Environmental Assessment Certificate and the Squamish Nation Environmental Assessment Agreement. Learn more about these changes and what we proposed.
Protecting the Skwelwil’em Squamish Estuary Wildlife Management Area
The 673-hectare Skwelwil’em Squamish Estuary Wildlife Management Area (WMA) plays an important ecological role and serves as habitat for wildlife. Our existing system has been operating underneath the WMA since 1991 safely and without incident.
To access the Woodfibre LNG site, a segment of the proposed expanded gas pipeline section needs to be installed underneath the WMA. We are committed to operating responsibly and mitigating potential environmental impacts.
In response to public and local Indigenous community input, FortisBC has proposed the following approach to installing the gas pipeline under the estuary:
- An underground tunnel would be built about 25 metres below the estuary waterbed. The new sections of gas pipeline will be installed within the tunnel.
- Tunnel construction would continue through the Monmouth Ridge Mountain and exit at the Woodfibre LNG site.

Indigenous feedback helps to improve our Eagle Mountain - Woodfibre Gas Pipeline Project
We value working directly with local First Nations to listen to their concerns and understand their perspective. We’re engaging with the following First Nations to discuss the expansion project details and listen to their questions and concerns:
One of our top priorities is to engage local communities so that they understand the work we're doing
Keeping the community informed
We value the importance of keeping the community informed about the project. One of the ways we do this is by meeting with community groups and stakeholders to provide project updates. A recent example of this is our presentation to the Rotary Club of Squamish in June 2021.
To ensure you’re staying up-to-date, subscribe to our email newsletter.

Tri-Cities Chamber and SHARE Society food drive
We joined and supported the Tri-Cities Chamber for their 2021 Christmas Luncheon, which featured a food drive for the SHARE Family & Community Services Society. In total, the drive collected over 600 pounds of food for families in need. We were thrilled to partner with the Chamber on this initiative, and will continue looking for similar opportunities to give back to the communities where we live and work

Squamish Days Loggers Sports Festival
Our team joined the Squamish community at the Squamish Days Loggers Sports Festival, which was back in action in September 2021. We were able to connect with hundreds of attendees and enjoyed sharing information and answering questions about FortisBC and the EGP Project. Congratulations to all the competitors, and we can’t wait to see the community at this event in future years.
A conversation with Bryan Couture
The Squamish Day Loggers Sports Festival celebrates the connection between Squamish and local industry. We spoke with Bryan Couture in 2016, then-president of the Squamish Days Loggers Sports Association, about the importance of the event to the community and how industry growth can benefit Squamish.
Questions from the community during 2020
We know you have questions, and our team is here to provide answers. In 2020, we held several virtual information sessions in Squamish and Coquitlam to ensure interactive opportunities for the public to ask questions and learn more about the project.
Our team compiled 30 questions from our August update to the Squamish community. We also compiled over 50 questions from all six sessions.
We’ll continue to keep the public informed as the project progresses.
FortisBC hosts another fun family event in Squamish community
In June 2018, we sponsored a free mini-golf and barbecue event at the Whistle Punk Hollow Adventure RV Park for the community of Squamish. More than 100 people visited our booth and learned more about our natural gas services and our project in the area.
Community grants support local initiatives
At FortisBC, we serve more than 135 communities across the province. Giving back to the communities where our over 2,400 employees live and work is an important part of our efforts to create a sustainable future for British Columbians.
We’ve been a part of the Squamish community for over 30 years. And we take our role as a good corporate citizen very seriously. The local recipients of our community investment grants include a wide-range of organizations that are working hard to make Squamish and the Sea-to-Sky region a better place to live.
Regulatory process
Environmental Assessment Office
In 2016 the project received approval from the provincial Environmental Assessment Office and Skwxwú7mesh Úxwumixw (Squamish Nation). In 2021 the project’s approval was extended for a further five years.
- Environmental Assessment Office Certificate
- Schedule A: Environmental Assessment Certificate Certified Project Description
- Schedule B: Environmental Assessment Certificate Table of Conditions
- Environmental Assessment Office Certificate Amendment 1
- Environmental Assessment Office Certificate Amendment 2 application
You can view all finalized environmental and condition management plans at the Environmental Assessment Office’s project portal.
BC Energy Regulator
We’ve applied for a permit through the BC Energy Regulator to discharge treated water generated from tunnel construction activities at the BC Rail and Woodfibre LNG sites in Squamish. All water generated through construction activities will be treated, prior to discharge, in accordance with the Environmental Management Act and to meet BC Water Quality Guidelines.
Details on the project and water management can be found in our application documents here.
