As I recall, it isn't all that far from Vancouver down to Bellingham. Surely you could find a copy of the Bellingham phone book and locate a place to buy this stuff.

I note that you do not necessarily live in Vancouver, though. Most of the population of BC lives near the border, but perhaps you do not. I would think that a clever person could simply dump several cans of this stuff into a gas can and smuggle it home. My guess is that no one looks for smuggled fuel additives.
