Gas prices are going up tomorrow across Canada but here's which spots have the savings
Fill up now or wait? It depends where you live. 👀

Gas prices in Canada are rising tomorrow — but not everywhere.
Heads up, Canada! Drivers in cities like Toronto, Calgary, Vancouver and Ottawa should brace for a squeeze at the pump as gas prices tomorrow are set to increase across most of the country.
Gas prices are heading up across several cities in Canada starting tomorrow, May 8 — and depending on where you live, the increase could hit harder than in other spots. Whether you're in Toronto, Calgary, Vancouver, Montreal or anywhere in between, the changes are expected to make a dent in your fuel budget.
But not everywhere is feeling the squeeze equally. While most spots will see small increases, a few lucky cities are holding steady — and some gas prices in Canada are even falling tomorrow.
If you're trying to figure out where the lowest gas prices in Canada — or even just your area — are, we've got the scoop.
Are gas prices going up tomorrow?
Yes — in most of the country, gas prices are set to rise on Thursday.
According to gas price predictions site Gas Wizard, major cities like Toronto, Ottawa, Calgary, Edmonton, Vancouver and Montreal will all see higher average prices for regular fuel.
That said, diesel users across Canada can breathe a sigh of relief, as the price of that fuel type should remain untouched across most of the country tomorrow.
The regular gas increases vary by city, but for many drivers, it means a slightly more expensive fill-up heading into the end of the week.
Where is gas going up tomorrow?
Gas Wizard is forecasting average price hikes of around 2 to 4 cents per litre in most major cities. The biggest jumps are happening in places like Kingston and Cornwall, Ontario — both expected to rise by 4 cents overnight.
Gas prices in Toronto and much of southern Ontario, Ottawa, Montreal, Vancouver, Calgary and many other cities are also climbing by around 2 cents.
But not everywhere is trending up. A few Ontario cities like Markham, Peterborough and Sudbury are actually set to drop by 3 to 4 cents per litre.
Other spots, including Niagara, Thunder Bay, Winnipeg, Saskatoon, the B.C. Interior and most of the Maritimes, are expected to stay flat.
So while the general trend is up, it's not universal — and depending on where you are, tomorrow might even bring a bit of relief.
Where is the cheapest gas in Canada?
Even with gas prices rising in many cities, some provinces are still holding onto affordable averages.
According to GasBuddy, as of Wednesday afternoon, Alberta currently has the lowest provincial average at just 123.4 cents per litre of regular gasoline. Ontario is close behind, sitting at 127.7 cents.
On the flip side, B.C. and Quebec continue to lead the high end, with provincial averages at 152.9 cents and 151.5 cents, respectively.
Here's a look at the cheapest individual station prices reported today, May 7, from GasBuddy:
- Alberta: CENTEX & GOmarket in Vegreville — 103.9 c/L
- Ontario: Bear Creek Express in Munsee-Delaware Nation (Chatham-Kent) — 110.9 c/L
- Manitoba: Western Nations Gas Bar (CO-OP) in Brandon — 115.5 c/L

- Vancouver, BC: 174.9 c/L
So if you're lucky enough to be in places like Kingston or Peterborough, you'll be seeing some of the lowest gas prices in the country tomorrow. But if you're in Vancouver or Montreal, start mentally prepping for that higher total at the pump — and maybe fill up today before it goes up.
Should you fill up now or wait?
If you're in one of the cities where prices are rising — and that includes most major cities like Toronto, Ottawa, Calgary, Edmonton, Vancouver and Montreal — it might be worth heading to the pump tonight.
Keep in mind that Gas Wizard's estimates are based on trends and average prices, not exact station-by-station predictions. And while GasBuddy provides real-time crowdsourced data, it might not always capture every deal in town. So if you see a price you like, it might be best to lock it in.
With summer on the horizon and seasonal fuel blends becoming the norm, prices might not stay low for long. These kinds of small bumps could become the new normal as demand goes up and production costs follow.
Stay tuned — and stay fuelled.
