On average, each litre of gas purchased in Ontario includes the Provincial Fuel Tax (14.7 cents per litre), the Federal Excise Tax (10 cents per litre) and the HST. Of those taxes, the first two are fixed amounts and not a percentage.
What makes up the price of a litre of Shell gasoline?
Four costs go into Shell's pump price: crude oil, taxes, refiner margin, and marketing margin.
Gasoline prices go up and down over time and vary from place to place, so the price breakdown for a litre of gasoline also varies.
40 - 55 per cent is crude oil costs (the raw material for making gasoline and diesel fuel)
25 - 35 per cent is federal, provincial and municipal taxes and the GST
10 - 25 per cent is the refiner's margin (the difference between what it costs to buy crude oil and the price refined gasoline sells for in the wholesale market which, in turn, is influenced by supply and demand)
4 - 6 per cent is the marketing (or retail) margin that covers retail stations’ expenses and profits.
