Toronto motorists enjoyed a brief reprieve on Friday when gasoline prices dropped eight cents per litre, thanks to the seasonal switch to winter-grade fuel. But the relief was short-lived—by Saturday, seven cents of that discount had already been clawed back, and the latest forecast suggests the remaining relief could be wiped out entirely, with prices set to climb even higher.
According to the CityNews Toronto price page, as of Wednesday morning, regular gasoline was listed at 183.9 Canadian cents per litre. En-Pro, a fuel price forecasting service, projects a six-cent increase effective Thursday, bringing the price to 189.9 cents per litre. CityNews cautions that this is an interim forecast and could be revised as market conditions evolve.
The forecast is for the dominant price at local stations, not a regulated rate, so individual retailers may post different prices. However, the week's pattern is unusually clear: the cheaper seasonal fuel specification produced a sharp initial drop, but wholesale pressure quickly overwhelmed that benefit.
Here's the week's price trajectory:
- Sept. 10: 187.9 cents per litre
- Sept. 11: 179.9 cents (down 8 cents, winter-grade gasoline arrives)
- Sept. 12: 186.9 cents (up 7 cents)
- Sept. 16: 183.9 cents (up 1 cent)
- Sept. 17 forecast: 189.9 cents (up 6 cents)
En-Pro analyst Roger McKnight attributed Friday's decline to the annual transition from summer to winter gasoline, which is cheaper to produce. That seasonal change lowered the starting point but did not shield Ontario from broader fuel market pressures.
The impact on consumers is significant. A 50-litre fill now costs about C$20.50 more than last September's high of 142.9 cents per litre. If Thursday's forecast holds, that gap widens to C$23.50 per fill. These figures are based on published prices and not a forecast of any household's total monthly fuel bill.
A separate survey from Kalibrate Canada offers a cross-check: it measured Toronto regular gasoline at 183.7 cents on Sept. 15, down slightly from the previous day. Its tax-exclusive price was 153.6 cents, and the estimated retail margin was 11.7 cents. That margin is not store profit; it must cover wages, rent, card fees, and other operating costs.
The inflation implications are already visible. Statistics Canada reported that gasoline prices rose 22.8% year-over-year in August, while headline consumer inflation was 3.0%. Excluding gasoline, CPI was 2.4%. September's daily pump moves will eventually be averaged into the next monthly reading, so one overnight forecast cannot by itself determine the inflation outcome or the Bank of Canada's policy response.
Ontario's provincial gasoline tax remains at 9 cents per litre, a rate made permanent as of July 1, 2025, according to the 2026 Ontario budget. There was no new provincial tax increase during this period.
Market forces, rather than taxes, are driving the volatility. Ontario gasoline prices are influenced by global crude oil, local retail competition, and North American wholesale benchmarks, with New York Harbor particularly relevant to Toronto. Gasoline and diesel prices are not economically regulated by the Ontario Energy Board, and with more than 3,265 retail sites, prices can vary widely.
The cleanest market read-through is to inflation-sensitive Canadian bonds and rate expectations, rather than a simple windfall for fuel retailers. A higher pump price can reflect higher wholesale costs rather than a wider retail spread. Therefore, Kalibrate's margin estimate, the Canadian dollar, and wholesale gasoline prices should be monitored alongside the sign price.
The strongest counterargument is volatility itself. Thursday's forecast could be revised, the winter-grade switch still leaves prices lower than they otherwise would be, and Toronto is not the whole province. A sustained move near 190 cents across several surveys would matter more than one forecast. For now, the useful conclusion is narrower: Ontario's expected seasonal relief has been too small to offset the forces lifting wholesale fuel costs.
