Coastal GasLink route: length and status

Where does the Coastal GasLink pipeline start and end?

The Coastal GasLink pipeline runs from the Dawson Creek area of northeastern British Columbia west to the LNG Canada terminal near Kitimat, on the B.C. coast. That coastal end point is the whole reason the line exists: it feeds natural gas to LNG Canada's plant, where it's cooled into liquefied natural gas (LNG) and loaded onto ships for export.

How long is the Coastal GasLink pipeline?

The route is about 670 kilometres (roughly 416 miles) end to end, built and operated by Coastal GasLink, a limited partnership operated by TC Energy.

What it crosses

From the Dawson Creek area, the line heads west through the Rocky Mountains and other mountain ranges of northern B.C. before dropping down to the coast at Kitimat. Along the way it crosses a large number of rivers, creeks, and lakes -- the operator's own materials point to the Morice River crossing near Houston, B.C. as a notable one, built as a tunnel roughly 11 metres under the riverbed rather than an open trench through the water. The route passes through the traditional territories of 20 First Nations, and the operator states it holds agreements with all 20 of their elected governments.

We're not going to try to reproduce a full list of every community, waterway, or right-of-way segment here -- that's exactly what the operator's own interactive map is for (linked in Sources below), and a written list would just be a worse copy of it.

Is the Coastal GasLink pipeline finished?

The pipeline is built and in service. Coastal GasLink reached commercial in-service in November 2024, with tolling applied retroactively to October 1, 2024, and the line carried gas behind LNG Canada's first export shipment on June 30, 2025. At this point the operator describes its work as final clean-up and reclamation along the right-of-way rather than active construction.
