(TORONTO) — Canadian Prime Minister Justin Trudeau has once again approved the contentious Trans Mountain pipeline expansion that would nearly triple the flow of oil from the Alberta oil sands to the Pacific Coast. The approval Tuesday comes 10 months after the Federal Court of Appeal halted the project and ordered Canada’s National Energy Board to redo its review of the pipeline, saying the original study was flawed and lacked adequate consultations with First Nations peoples. Trudeau’s government first approved it in 2016, and he was so determined to see it built the government bought the pipeline. The pipeline expansion would triple the capacity of an existing line to ship oil extracted from the oil sands in Alberta across the snow-capped peaks of the Canadian Rockies.
