The Canadian government has a website concerned with vehicle fuel economy. The page presents you with a series of filters, such as year, vehicle manufacturer, transmission and type of fuel. You are given a list of all vehicles that match the filter. Each vehicle has its highway and city fuel economy rating according to the Canadian government, along with the amount of liters used in a year by average driving and an estimate of dollars per year in gasoline costs. One more tool you can use if you are looking around to buy the least gas guzzling option available.
