 “Any decision by the B.C. government to limit the flow of bitumen would be outside the province’s jurisdiction.”
The federal government does control interprovincial pipelines. However, provincial governments have shared control of related matters like environmental protection. This means both the federal and provincial governments could potentially impose regulations on a project like the Trans Mountain pipeline expansion. Depending on arguments made by B.C. in an upcoming legal case, there’s at least a chance the courts will find the province has jurisdiction to limit bitumen flow in some capacity.
