September 2025. Kalibrate's Canadian Petroleum Price Snapshot

Gasoline:

Retail gasoline prices declined 2.2 cents per litre to 144.2 in September

In September, gasoline prices in Canada fell 2.2 cents per litre. Although crude oil prices experienced a slight decrease during September, the primary reason for the lower gasoline prices over the month was a decline in wholesale gasoline prices, which fell by 4.6 cents per litre. High refinery utilization in Canada at the beginning of September (averaging 97%) likely boosted gasoline production during a period when demand was waning, as the busy summer driving season came to an end, leading to lower prices. Additionally, refiners switched to winter-blended fuel mid-September — a cheaper blend to produce — further contributing to the decrease in gasoline prices in September.

Although most Canadian markets saw falling gasoline prices in September, there was some regional variation, with some markets even experiencing price increases.

In September, gasoline prices in North Bay, Ontario, saw the largest increase, with retail prices climbing by 10.4 cents per litre over the month, ending at 132.1. In contrast, the biggest decrease occurred in Winnipeg, Manitoba, where prices dropped 14.6 cents per litre, ending the month at 128.9. By the end of September, gasoline prices in Canada were highest in Vancouver, British Columbia, at 168.0 cents per litre, and lowest in Lethbridge, Alberta, at 122.5 cents per litre, a difference of 45.5 cents per litre.

Diesel:

In contrast to gasoline prices, most markets in Canada saw higher diesel prices in September, with the Canadian average rising 2.5 cents per litre over the month. After distillate fuel inventories reached multi-year lows earlier this year in several North American markets, including Canada, where Statistics Canada data show diesel inventories reached their lowest level in over five years in May (Table 25-10-0081-01), inventories have since begun to build, a result of strong refinery utilization in both the U.S. and Canada. However, data available up to July indicate that distillate inventories in Canadian coastal markets are still below typical levels. In the West, this is likely linked to changes in U.S. biofuel tax credits since the start of the year, which have boosted demand for conventional diesel along the North American West Coast, keeping diesel prices in these Canadian markets elevated above the national average. While on the East Coast, the higher use of distillate fuel for home heating probably contributed to rising prices in September as summer comes to an end and suppliers build inventories ahead of winter.

Looking at regional price trends, the largest retail diesel price increase in September occurred in Woodstock, New Brunswick, where prices rose 6.3 cents per litre to end the month at 158.3. The largest diesel price decline occurred in Brantford, Ontario, where prices fell 3.1 cents per litre, ending the month at 130.1, the lowest recorded price in Canada at the end of September. In contrast, the highest price was recorded in Vancouver, British Columbia, at 180.8 cents per litre, a full 50.7 cents per litre above Canada’s lowest price
