U.S. beef (and most other meats and food items except for certain raw fruit & veg that are from the U.S.) is fine for import into Canada (done it into Canada several times albeit by land crossings), and no limitations for personal consumption AFAIK. FWIW, ribeye sells for $5-6/lb (lower less-marbled grade) in the smaller independent supermarkets in Vancouver though the big chains and those in Whistler) often sell for much more. Some places sell certified Angus beef for about 1.2-3x more (especially if organic). No idea about the Patagonia Toothfish.
