Hey Ontario drivers, brace yourselves — Ontario gas prices are set to rise tomorrow, but we've got the scoop on where you can still fill up for less. If you've been tracking gas prices in Ontario, you'll want to plan your fill-up strategically to avoid paying more at the pump.
What's happening?
According to Gas Wizard, starting tomorrow, August 31, gas prices are expected to rise by 2 cents per litre in major cities across Ontario. If you're in Toronto, expect to pay around 155.9 cents per litre for regular gas, 185.9 cents for premium, and 151.9 cents for diesel. Ottawa will likely see similar increases, with regular gas priced at 154.9 cents per litre.

- Sudbury: Surprisingly, prices will slightly decrease, with regular gas at 158.9 cents per litre.
- Peterborough: Regular gas drops marginally to 151.3 cents per litre — so, definitely a good place to fill up if you're nearby!

Expert insights
We reached out to gas analyst Dan McTeague for more information on what to expect in the coming weeks. According to McTeague, while tomorrow's price hike is a small inconvenience, the bigger picture offers some relief.
"The real news is that in two weeks, we go back to winter blend gasoline, which will almost certainly see pump prices for gasoline drop by 5-7 cents a litre," McTeague explains. However, he also notes that diesel prices are likely to rise by a similar amount.
National context
According to the Canadian Automobile Association (CAA), the national average for gas prices today is 156.2 cents per litre. This is still well below the year's high of 172.4 cents per litre back in April, but it's a good idea to fill up before tomorrow's increase hits.
What's next?
With prices set to rise tomorrow, your best bet is to fill up today if you're in Toronto or Ottawa. Keep an eye on the upcoming switch to winter blend gasoline, which should bring some relief at the pumps in the near future.
Remember: Prices can vary slightly by location, so always check your local gas station before filling up.
