In Canada, each province has their own liquor board, In Quebec, you can buy wine and beer in grocery stores, but liquor is only available through government outlets.. You won't find liquor at Costco for example,,, but they are allowed to sell beer and wine. I can "import" products internationally if I want to, however, there are very strict rules and conditions, and the final purchase purchase price will be determined by the province. I cannot purchase from a retailer or distributor; the purchase must be made directly from a bottler/producer. Once a proposed purchased is agreed upon, that proposal has to be sent to the Quebec Liquor Board, where they'' either permit or disallow the purchase,,, and levy their "appropriate" tax.
In neighboring Ontario, I believe that beer sales are done through the government Brewer's Retail Outlet.(The Beer Store), and they sell only beer,,, no wine, no liquor. Conversely, you can find "some" beer in the provincial liquor store (LCBO), but it's mostly imports and micro-brewery products.
