Ontario Gas Prices Set to Drop Up to 23¢/L Tomorrow Check Out the Best Places to Refuel

If you’re planning to hit the road soon, hold off on filling your tank—Ontario drivers are in for a pleasant surprise. Starting April 1, gas prices across the province are expected to plummet, thanks to a major policy shift. This could mean serious savings at the pump, especially if your tank is running low.

Let’s break down everything you need to know about this unexpected gas price dip, including where to find the cheapest fuel, why prices are dropping, and whether it’s better to fill up now or wait.

Why Are Ontario Gas Prices Dropping?

The sudden drop in gas prices is tied directly to the elimination of the federal fuel charge, commonly known as the consumer carbon tax. This tax, which added 17.61 cents per litre to the cost of gasoline, is officially gone starting tomorrow.

This move comes as part of Prime Minister Mark Carney’s promise to remove the carbon tax, a decision that’s already making waves at the pump. The removal of this surcharge means that gas stations across Ontario will pass those savings directly to consumers.

How Much Will You Save?

The impact varies by region, but here’s the expected price drop across Ontario cities:

• St. Catharines: Down 23¢/L to 133.9¢/L
• Toronto, Markham, Oakville: Dropping 20¢/L to 136.9¢/L
• Ottawa: Down 20¢/L to 135.9¢/L
• London: A significant drop of 18¢/L to 130.9¢/L
• Niagara, Barrie, Waterloo: Prices falling 19¢/L to 133.9¢/L
• Windsor: A more modest drop of 12¢/L to 133.9¢/L

Premium fuel and diesel are seeing even bigger drops. In the GTA, premium gas prices could fall by as much as 30¢/L, while diesel might drop by 24¢/L, and in some parts of southwestern Ontario, diesel could be 28¢/L cheaper.

Where Can You Find the Cheapest Gas in Ontario?

If you’re looking to stretch your dollar the furthest:

• London is expected to have the lowest average price at 130.9¢/L.
• Mississauga and Oshawa follow closely with 132.9¢/L.
• Peters Petro in Moraviantown First Nation (Chatham-Kent) currently holds the title for the cheapest gas in the province at just 129.7¢/L, according to GasBuddy.

Will These Low Prices Last?

While this drop is great news, it’s not permanent. Experts, including Dan McTeague from Canadians for Affordable Energy, warn that gas prices could start rising again as early as next week.

Why? The switch to summer-blend gasoline adds extra costs because it’s more expensive to produce. This seasonal change can push prices up by 5–6¢/L or more. Additionally, a weakening Canadian dollar and rising global demand could also reverse the savings sooner than expected.

Should You Fill Up Now or Wait?

If you can afford to wait, hold off until tomorrow. The savings will be noticeable across Ontario, especially in cities like London, St. Catharines, and Ottawa.

However, if you’re in places like Sudbury or Kingston, where the price drops are slightly less dramatic, the difference might not be as significant.

Final Thoughts: Make the Most of It While It Lasts

Tomorrow is shaping up to be a great day for Ontario drivers. Whether you’re commuting, road-tripping, or just topping off your tank, this is the perfect time to save money on fuel.

But remember—these savings might not last long, so fill up while you can. Happy driving, and enjoy the lower prices while they last! 🚗⛽
