If you're in Calgary, Willow Park has a pretty good wine selection. Goes without saying, JimBob's liquor in Three Hills probably doesn't.
I'm not sure about the practical and the numbers involved. In principle, if anything in the world should be taxed, liquor is pretty high up on that list. Think about the social cost - the number of fights, domestic police calls, drunk tank visits, traffic accidents, unintended pregnancies and STD transmissions...
Again, I doubt the money actually goes there but in principle I have nothing against pay-per-use taxation. I've also made an effort to reduce my consumption.
EDIT: I just re-read the article and I temper my stance a little. Sounds like the LCBO runs a pretty socialist business.
