Upon completion, the Coastal GasLink will be a 670 km (420 mile) pipeline designed to transport natural gas from the Montney gas-producing region near Dawson Creek, B.C. to the LNG Canada facility in Kitimat. The pipeline will have an initial capacity of approximately 2.1 billion ft3/d with the potential for expansion of up to approximately 5 billion ft3/d.

Construction activities are expected to begin in early 2019 with a planned in-service date in 2023.
