Chris, this is the first I've heard of your Canada trip -- are you driving all the way from Mexico?? What's your route through Canada? Sounds like we need a separate thread just to give you unsolicited advice!! ;)
And yes, booze in Canada is very expensive. On the bright side, I drank a little less while I was there and lost some weight. I gained it back when we returned to the US, but it was fun while it lasted.
A friend of mine told me that although California wines are far more expensive in Canada than in the US, Italian wines are about the same as in the US. Don't know why that would be true.
