Supreme Court to hear B.C. case attempting to halt Trans Mountain expansion

OTTAWA — Canada’s high court will hear arguments Thursday on whether British Columbia can stop Alberta from shipping heavy oil through the Trans Mountain pipeline without a permit.

B.C.’s NDP government brought the case in 2018 as it worked to fulfil an election promise to stop the Trans Mountain pipeline expansion project.

The province argues it should be able to limit the contents of the pipeline, because it would bear the brunt of environmental harm from any spill.

The federal government will argue that B.C.’s move would give the province a veto over interprovincial projects it doesn’t like, counter to the constitutional authority Ottawa has over any transportation project that crosses provincial boundaries.
