Drivers across Toronto and the GTA are expected to get some relief at the pumps this week, with gas prices forecast to fall by 9 cents per litre early Thursday morning.
According to En-Pro’s forecast reported by CityNews, the average price for regular gas in Toronto and the GTA is expected to drop at 12:01 a.m. on Thursday, May 28, 2026, from about 183.9 cents per litre to 173.9 cents per litre.
Best Time to Fill Up This Week
For GTA drivers who still have enough fuel to wait, the best time to fill up is Thursday morning or later, after the expected midnight price drop takes effect.
Drivers who need gas on Wednesday should consider buying only enough to get through the day, then filling the tank after prices fall. At a 9-cent drop, a 50-litre fill-up would save about $4.50 compared with filling up before the change.
Gas Wizard listed the GTA average at 183.9 cents per litre on Wednesday, May 27, with no change from Tuesday.
Why Gas Prices Are Going Down
The dip comes as oil prices ease after sharp increases tied to the Iran conflict and concerns over global supply. Axios reported oil prices fell by about $5 per barrel after signs of a possible U.S.-Iran peace deal, easing some pressure in energy markets.
Gasoline prices move with several factors, including crude oil costs, wholesale markets, refining conditions, and regional supply and demand. Canadian Fuels says retail prices rise or fall quickly because wholesale markets shift daily.
Price Forecast Still Subject to Change
The forecast gives GTA drivers a clear reason to wait before filling up, but prices remain volatile. CityNews noted the prediction represents an interim forecast and could be revised because of current market fluctuations.
For now, the message for Toronto, Mississauga, Brampton, Vaughan, Markham, and other GTA drivers is simple: avoid a full fill-up Wednesday if your tank allows it, and head to the pumps Thursday after the expected 9-cent drop.
