The Trans Mountain Pipeline is a major oil pipeline in Canada that transports crude oil and refined products from Alberta to British Columbia. It spans approximately 1,150 kilometers and has been in operation since 1953. The pipeline is owned by Trans Mountain Corporation, which is a subsidiary of the Canadian government. In recent years, the pipeline has been the subject of significant public debate and legal challenges due to concerns about environmental impacts and Indigenous rights. The expansion project aims to increase capacity and is designed to facilitate the transportation of oil to the west coast for export, particularly to markets in the Asia-Pacific region.
