World oil prices are constantly fluctuating. However, these price variations are not necessarily reflected in the price paid by consumers at the pump. This is because in Canada, the price of oil makes up only about a third (36% on average in 2015) of the pump price, which is less than federal, provincial, territorial and sometimes municipal taxes (43% on average in 2015).
In fact, the rack price (the price paid by wholesalers) is a better indicator of the pump price, because the rack price includes refining margins and transportation costs, and because the time it takes for gasoline to move from the refinery to the pump is generally short.

The various taxes make up one of the largest components of Canadian retail gasoline prices
As shown in Figure 2, there are four key components of Canadian retail gasoline prices:
- the price of oil;
- refining and retailer margins, including refining and retailing costs and profits;
- various federal taxes (excise tax, goods and services tax (GST)); and
- various provincial taxes, (provincial/territorial sales taxes, harmonised sales taxes and certain municipal taxes.

Figure 3 presents the various components of retail gasoline prices in Whitehorse, Yellowknife, Vancouver, Calgary, Regina, Winnipeg, Toronto, Montreal, Saint John, Halifax, Charlottetown and St. John’s.
For example, in Montreal, federal, provincial and municipal taxes accounted for 43% of the retail gasoline price in 2015. Only three Canadian cities—Vancouver (11.0 cents per litre), Victoria (3.3 cents per litre) and Montreal (3.0 cents per litre)—impose an additional tax on gasoline.

Daily fluctuations in retail gasoline prices depend more on the rack price of gasoline
Crude oil prices, set on international markets, generally have a longer-term impact on pump prices. In other words, the pump price fluctuates as the commodity price makes its way down the extraction, transportation and processing chain to consumers. Figure 4 presents the various stages in the resource chain.

Value of the Canadian dollar cushions the impact of oil price fluctuations
Since Canada is a crude oil producer, fluctuations in world oil prices generally have an impact on the value of the Canadian dollar. As a result, a drop in the price of oil generally drives down the value of the Canadian dollar, while an increase in the price of oil generally has the opposite effect.
Since crude oil is traded in U.S. dollars and Canada imports 37% of its oil consumption, fluctuations in crude oil prices are cushioned by fluctuations in the Canadian dollar. For example, oil imports become more expensive when lower oil prices drive down the value of the Canadian dollar.
Rack price fluctuations result in equivalent, symmetrical fluctuations in pump prices
Empirical studies confirm that fluctuations in pump prices are influenced by the rack price. As well, changing rack prices are shown to result in an equivalent change in pump prices. Lastly, it has been shown that there is no asymmetry in the setting of pump prices—rises and falls in pump prices occur in step with the same change in the rack price.
