Not legal to sell, but legal to possess. I go across the border and stock up at REI in Bellingham. No problems bringing it back across. Apparently this is quite common for lower mainland residents. When I brought 4 big bottles of the stuff up to the register, the first thing they asked was if I was Canadian.

Ah yeah that's a good distinction that I should have made.

I think I read somewhere that it's used by the Canadian Forces as well, but not made available to civilians.

I wonder why you can't sell it here. They even recommend it on the government's travel site:
