While the majority of Canadians are English speaking, the province of Quebec is predominantly French as are parts of New Brunswick, Ontario and Manitoba. Quebec is the most liberal of the provinces allowing the sale of beer and spirits every day of the week. Ontario doesn't allow the sale of alcohol on Sundays. You can of course have a drink with a meal in a restaurant during normal operating hours in most provinces.
Ice is readily available at most corner stores and beer can usually be purchased cold.
