Crossing the US/ Canada Border with Liquor and Tobacco

How many smokes and beer am I allowed?

As long as you meet the age requirement set by the province where you enter Canada (19 in Ontario), you may import 1.5 litres of wine or 1.14 litres (40 ounces) of liquor OR 24 x 355 ml cans or bottles of beer or ale from the US into Canada. Those over 18 years of age may bring 200 cigarettes, 50 cigars, 200 grams of manufactured tobacco and 200 tobacco sticks from the US into Canada.

Canadians returning to Canada from the U.S., after an absence of more than 24 but less than 48 hours are allowed to bring back $50 Can. worth of goods duty free, per person. (This exemption does not include tobacco and alcohol products.) 

Those Canadians away for more than 48 hours may bring back $200 worth of goods;
Canadians may import $750 worth of goods, duty free, after an absence of 7 days. (The latter two exemptions do allow for tobacco and alcohol products.) Any amount of alcohol in excess of 45 liters will not be allowed entry.
