The Supreme Court of Canada has rejected BC’s move to regulate what can flow through an expanded Trans Mountain pipeline from Alberta. The BC government wanted to require provincial permits before heavy oil could be shipped through pipelines in the province. The twinned pipeline, with roughly twice the capacity of the original, would carry only diluted bitumen, a heavy crude produced in Alberta’s oilsands. The existing pipeline is to continue to ship mainly refined petroleum products like gasoline, and light crude.
