Drivers across the province can breathe a small sigh of relief as Ontario gas prices are expected to dip in many cities tomorrow.

According to predictions site Gas Wizard, gas prices in Toronto, Markham and Oakville are all expected to fall by four cents on Friday, landing at 132.9 cents per litre. It's not a massive drop, but every little bit helps when you're filling up for that weekend road trip or daily commute.

The most significant drop is in Brampton, where prices are predicted to tumble by 10 cents, hitting 126.9 cents per litre for regular fuel. That's one of the lowest prices for a major city in the province. The Flower City's prices had just increased by 8 cents per litre on Thursday.

Other Southern Ontario cities like Mississauga, Waterloo, Oshawa, Barrie, London and Hamilton are also set to see drops, all falling to 126.9 cents per litre — with slight differences in how much they're going down.

Ottawa and Kingston should dip to 124.9 cents per litre, while Windsor is the outlier, seeing a slight increase of one cent to 122.9.

But if you're really looking to save, there's one place that's blowing everyone else out of the water.

According to GasBuddy, the cheapest gas station in Ontario today is Smokes Fuel and Convenience in Alderville First Nation, just northeast of Cobourg. Their pump price is 103.9 cents per litre for regular — nearly 30 cents less than you'll pay in Toronto.
