In the short run. In the longer run, if the U.S. displaces Canadian imports of oil, Canada will simply build up the capacity to move more of it to the West Coast for export. In during the interim, China can simply look to pick up any slack capacity from Russia, especially if India has to reduce some of their Russian imports in order to paper over a trade agreement with the U.S.
There are a lot of Canadians puffing out their chests right now wanting to sell China everything. They seem to think that makes them feel better. They'll wise up when they think it through.
Besides - they've got a problem. The tribes don't want a pipeline running through BC to any of Canada's Western ports. And guess who owns most of British Columbia (or at least can tie anything up in knots with the "unceded land" claims in court).
