At terminals,
retailers blend their gasoline with proprietary blends of performance and efficiency-enhancing additives, as well as with ethanol, according to federal and provincial renewable fuel requirements. As regional distribution centres, terminals are used as reference points for pricing at gasoline retail stations. Many terminal operators, including Petro-Canada, Shell Canada, and Valero, post their wholesale, or “rack”, prices publicly. Rack prices factor in costs incurred throughout the supply chain, including the price of crude oil, refining margins, and costs of transportation to the terminal, including tolls on gasoline-carrying pipelines. Aside from a relatively small marketing margin applied by the retailer, the entire cost of production (including profit margins) is included in the rack price. Government taxes applied at the pump comprise most of the difference between rack prices and pump prices.
As of 2017, there are 78 terminals registered with Environment and Climate Change Canada. All terminals in Canada have truck-offloading capacity, and some also have capacity to offload onto ships, railcars, or even pipelines. Logistically, tanker trucks are the most practical and economical way of getting gasoline to retail stations, because they allow for flexibility in both the volume and destination of each shipment. In the Atlantic Provinces, many terminals also have marine offloading capabilities, which allow them to supply smaller towns along the coast.
