About Coastal GasLink

Connecting lower-carbon Canadian LNG to global markets

Spanning 670 kilometres (416 miles), the Coastal GasLink project will safely deliver natural gas from northeastern B.C. to the LNG Canada facility in Kitimat, B.C., From there, LNG Canada will prepare it for export to global markets by converting the gas to a liquefied state (LNG). Coastal GasLink’s role is to ensure the safe transportation of natural gas from exporters and producers to LNG Canada’s facility. The pipeline will deliver 2.1 billion cubic feet per day (bcf/d) of natural gas with the potential to deliver up to 5 bcf/d, through additional compression along the route.

The approved Coastal GasLink route was determined by considering Indigenous, landowner and stakeholder input, the environment, archaeological and cultural values, land use compatibility, safety, constructability and economics.

Why is Coastal GasLink important?

It heats our homes and powers our lives. Canadian Liquified natural gas (LNG) represents a significant solution to supporting the global energy transition to cleaner-burning energy sources, and Coastal GasLink will help it get there. The Project is subject to some of the most stringent regulatory requirements in the world to ensure the safety and protection of the environment, while providing a lower-emitting energy option to offset coal-fired energy generation in global markets. Exporting the energy to Asian markets, where coal-fired electricity is commonly used, will be facilitated by Coastal GasLink and delivered by LNG Canada.

Timeline and milestones

TC Energy is selected by LNG Canada to design, build, own and operate Coastal GasLink. We begin our ongoing engagement process, followed by environmental and engineering studies along the proposed route.

Coastal GasLink files the Environmental Assessment Application with the BC Environmental Assessment Office and a detailed project design application to the BC Oil and Gas Commission. The project’s conditional Environmental Assessment Certificate CGL-external-link-popout.png is awarded October 24, 2014.

Field work continues, along with development of plans and strategies to fulfill regulatory conditions.

Field work continues so the Coastal GasLink team can gather further details about the approved route and the South of Houston Alternate Route (SHAR).

Coastal GasLink filed its amendment applications for the South of Houston Alternate Route with the B.C. Environmental Assessment Office and the Oil and Gas Commission in November 2017. Coastal GasLink’s consideration of a proposed alternate route was entirely initiated as a potential solution to the feedback received from First Nations groups in the area.

In late 2014, Coastal GasLink initiated a program to provide local First Nations groups with the opportunity to participate in field study activities, information sharing and intergenerational transfer of traditional and cultural knowledge along sections of the Coastal GasLink pipeline corridor.

After extensive consultation with First Nations people from various groups through that program, Coastal GasLink initiated additional studies and engineering work to create the South of Houston alternate option to help further reduce effects on traditional and cultural land.

Coastal GasLink was given approval for the South of Houston Alternate Route by the Environmental Assessment Office in May 2018.

On Oct. 15, 2019, the B.C. Environmental Assessment Office approved a five-year extension CGL-external-link-popout.png to the previously issued Environmental Assessment Certificate.

Coastal GasLink received approval from the Oil and Gas Commission (OGC) on May 1 of an application to amend the pipeline permit for construction of the re-routed section known as the South of Houston Alternate Route (SHAR).

On Oct. 15, 2019, the B.C. Environmental Assessment Office approved a five-year extension to the previously issued Environmental Assessment Certificate.

Coastal GasLink announced it will proceed with construction on the project following a positive Final Investment Decision from its partner, LNG Canada, on October 2, 2018.
