I doubt it seeing as there are constraints on liquor licenses in Quebec. I'll try and ask my dad about it as well since he has one. From Wikipedia:
The province of Quebec has its own special laws concerning selling liquor and acquiring a liquor license. The Régie des alcools, des courses et des jeux is in charge of liquor distribution and sets the laws on liquor consumption.The permits authorizing the sale or service of alcoholic beverages within the territory concerning liquor permits concluded between the Government and a Mohawk community are determined in the agreement and issued by the authority designated in the agreement. For example, in Quebec all places that are able to receive a liquor license except grocery stores (available but until 11pm ) are able to operate every day, from 8 o’clock in the morning to 3 o’clock in the morning in selling liquor. In Quebec, strong liquors and spirits (generally over 15%-20% abv.) are restricted for sale only in SAQ outlets (provincially-owned liquor retailers) as well at bars and other establishments with the requisite permit. All other types of liquor, as well as beer, shooters and other alcohol-derivative beverages are permitted to be sold at gas stations as well as supermarkets.
