I'll take the last one first.
The reason why some of the upgraders have been cancelled is because of the underlining economics of it. It's already marginal or worse to upgrade the oil, the bitumen, in Alberta relative to adding an upgrader onto a big refinery in the U.S.
I mean, the pipelines can ship light crude oil or bitumen. The existence of the pipelines is not what kills the upgraders. It's the underlying economics and the challenge they have.
