The Coastal GasLink pipeline is a TC Energy natural gas pipeline under construction in British Columbia, Canada. Starting in Dawson Creek, the pipeline's route crosses through the Canadian Rockies and other mountain ranges to Kitimat, where the gas will be exported to Asian customers. Its route passes through several First Nations peoples' traditional lands, including some that are unceded. Although approved by 20 First Nations' elected councils, the hereditary chiefs of the Wetʼsuwetʼen people withheld their approval on ecological grounds and organized a blockade of construction within the Wetʼsuwetʼen peoples' traditional lands.
