Gasoline prices across Toronto and the Greater Toronto Area are set to increase by six cents on Thursday, reaching 189.9 cents per litre, while diesel will climb by 11 cents, according to industry data. The adjustment takes effect on September 17, 2026, and follows a period of price volatility that has characterized the market throughout the month.
Roger McKnight, chief petroleum analyst at En‑Pro International, confirmed the forthcoming changes, noting that the modest rise in gasoline aligns with broader trends in the regional fuel market. He did not provide additional details on the drivers behind the shift, but the announcement comes as consumers and businesses alike monitor fluctuating costs.
The new gasoline rate of 189.9 cents per litre represents the latest figure after a series of adjustments that have left motorists watching the pump closely. Diesel, often used by commercial fleets, will see a price increase of 11 cents per litre, a change that could affect operating expenses for transportation and delivery services throughout the GTA.
Market observers have pointed to the month’s volatility as a factor in the timing of the price update. While specific causes for the recent swings were not disclosed, the pattern suggests that supply and demand dynamics, as well as broader economic conditions, continue to influence fuel pricing in the region.
Consumers can expect the new rates to be reflected at service stations across Toronto and surrounding municipalities starting Thursday morning. The changes are part of the regular price review cycle that occurs in response to market movements, ensuring that retail fuel prices remain aligned with wholesale costs and other influencing factors.
The upcoming adjustment adds to the ongoing conversation about transportation costs in the province, as residents and businesses plan for the impact of higher fuel expenses in the weeks ahead.
