Just across the border are a half dozen refineries with a combined output of about 5 times BC's demand, they should have some spare capacity. Like them, the Burnaby refinery could use Alaskan crude and make up the difference. Shut down that pipeline completely.

I suggest you do a little research on the existing Trans Mountain. 53% of its capacity goes to those WA refineries because we don’t have the refinery capacity to supply our needs. Only 33% goes to Burnaby.
