Supreme Court to hear B.C. case attempting to halt Trans Mountain expansion
OTTAWA — The B.C. government will ask Canada’s high court Thursday to give it authority over what can flow through the expanded Trans Mountain pipeline from Alberta.
The case is a make-it-or-break-it affair for the multibillion-dollar project: if B.C. is allowed to prevent heavy oil from flowing through the pipeline, it would crush the expansion’s entire reason for being. It is also a significant case for the federal government, which bought the pipeline in 2018 when B.C.’s court challenge convinced Kinder Morgan Canada the political opposition created too much risk that the project would never be completed.
The federal government will argue that letting B.C. regulate what can flow through the pipeline would give the province a veto over interprovincial projects it doesn’t like, counter to the constitutional authority given to Ottawa over any transportation project that crosses provincial boundaries.
B.C.’s NDP government, which was elected in 2017 in part on a promise to oppose the expansion, acknowledges the Constitution but says B.C. has authority to protect its environment. There, the province argues it should be able to restrict heavy oil flows in the pipeline because it is B.C. that will bear the environmental brunt of any spill if the pipeline ruptures.
