Why Canada Gas Prices Are Fluctuating in Canada
Gas prices in Canada are influenced by a complex mix of factors, including global crude oil prices, refinery operations, seasonal fuel blend changes, and regional taxes.
In 2025, the removal of the federal consumer carbon tax in most provinces has led to an average savings of 11 cents per litre, per the Canadian Taxpayers Federation.
However, local variations—such as British Columbia’s high provincial taxes or Alberta’s proximity to oil production—create significant price differences across the country.
As of June 4, 2025, the national average gas price is 135.6 cents per litre, down 2.7 cents from last week and nearly 25 cents lower than last year, largely due to the carbon tax cut.
Yet, with tomorrow’s predictions showing double-digit swings in some cities, drivers need to stay informed to make cost-effective decisions.
British Columbia: A Tale of Price Hikes and Drops
British Columbia’s gas prices are among the most volatile in Canada, with tomorrow’s predictions showing a stark contrast between coastal and interior cities.
Predicted Gas Prices for Thursday, June 5, 2025
- Victoria: 169.9 c/L (+10¢)
- Vancouver: 164.9 c/L (+1¢)
- Kamloops: 150.9 c/L (+1¢)
- Prince George: 133.9 c/L (-7¢)
- Kelowna: 131.9 c/L (-9¢)
Analysis
Victoria faces the steepest increase in Canada, jumping 10 cents to 169.9 c/L, making it the priciest major city.
Vancouver’s modest 1-cent hike keeps it among the top-tier expensive markets.
In contrast, Kelowna’s 9-cent drop offers the largest savings in the province, with Prince George also seeing relief at 7 cents lower.

This 38-cent gap between Victoria and Kelowna highlights B.C.’s regional disparities.
Should You Fill Up Now or Wait?
Victoria and Vancouver: Fill up today to avoid tomorrow’s price hikes, especially in Victoria, where the 10-cent jump is significant.
Kelowna and Prince George: Wait until tomorrow to capitalize on the 9-cent and 7-cent drops, respectively.
Kamloops: With only a 1-cent increase, the decision is less critical, but filling up today might save a small amount.
Why the Variation?
B.C.’s high gas prices are driven by provincial taxes and reliance on U.S. refineries, which face seasonal maintenance and summer blend transitions.
Recent refinery issues in California have also caused “lumpiness” in price fluctuations.
Prairie Provinces: Savings in Alberta, Stability Elsewhere
The Prairies show a mix of significant savings in Alberta and steady prices in Saskatchewan and Manitoba.
Predicted Gas Prices for Thursday, June 5, 2025
- Calgary, AB: 124.9 c/L (-10¢)
- Edmonton, AB: 125.9 c/L (-8¢)
- Saskatoon, SK: 134.9 c/L (no change)
- Regina, SK: 133.9 c/L (no change)
- Winnipeg, MB: 131.9 c/L (no change)
Analysis
Alberta drivers are in luck, with Calgary expecting the largest single-day price drop in Canada at 10 cents, and Edmonton close behind at 8 cents.
These reductions align Alberta with some of the lowest gas prices nationally, thanks to its proximity to oil production facilities.
Saskatchewan and Manitoba, however, see no change, with prices hovering near the national average of 135.6 c/L.
Should You Fill Up Now or Wait?
Calgary and Edmonton: Wait until tomorrow to save 8-10 cents per litre, especially if you have a large tank.
Why the Variation?
Alberta’s low prices stem from its oil production hub, which reduces transportation costs.
Saskatchewan and Manitoba, while stable, face higher distribution costs, keeping prices closer to the national average.
Ontario: A Mixed Bag of Increases and Decreases
Ontario’s gas prices are a patchwork, with some cities facing hikes and others enjoying drops.
Predicted Gas Prices for Thursday, June 5, 2025
- Brampton: 136.9 c/L (+8¢)
- Toronto, Markham, Oakville: 136.9 c/L (+2¢)
- Mississauga, Niagara, Oshawa, St. Catharines, Waterloo: 130.9 c/L (+2¢)
- Sudbury: 133.9 c/L (no change)
- Thunder Bay: 132.9 c/L (-4¢)
- Barrie: 130.9 c/L (-4¢)
- Cornwall: 129.9 c/L (-1¢)
- London: 128.9 c/L (no change)
- Hamilton: 128.9 c/L (-6¢)
- Kingston: 127.9 c/L (-3¢)
- Ottawa: 126.9 c/L (no change)
- Peterborough: 123.9 c/L (-6¢)
- Windsor: 121.9 c/L (-6¢)
Analysis
Brampton faces a sharp 8-cent increase, while Toronto and other GTA cities see a modest 2-cent rise.
Meanwhile, Windsor, Peterborough, and Hamilton are set for 6-cent drops, with Windsor offering the lowest price in Ontario at 121.9 c/L.
This variability reflects Ontario’s reliance on U.S. fuel markets, particularly New York Harbour, which recently switched to summer blends.
Should You Fill Up Now or Wait?
Brampton, Toronto, Markham, Oakville, Mississauga, Niagara, Oshawa, St. Catharines, Waterloo: Fill up today to avoid the 2-8 cent increases.
Windsor, Peterborough, Hamilton, Kingston, Barrie, Thunder Bay, Cornwall: Wait until tomorrow to benefit from drops ranging from 1-6 cents.
Why the Variation?
Ontario’s prices are tied to global oil markets and the switch to summer gasoline blends, which add 5-10 cents per litre due to lower butane levels.
The carbon tax removal has helped keep prices lower than last year, but regional differences persist due to distribution costs and local taxes.
Quebec: Steady Prices with a Slight Uptick in Montreal
Quebec’s gas prices are relatively stable, but Montreal remains one of Canada’s priciest markets.
Predicted Gas Prices for Thursday, June 5, 2025
- Montreal: 162.9 c/L (+2¢)
- Quebec City: 150.9 c/L (no change)
Analysis
Montreal’s 2-cent increase keeps it among the most expensive cities, while Quebec City holds steady.
Quebec’s cap-and-trade system, separate from the federal carbon tax, means the province didn’t benefit from the tax cut, contributing to higher prices.
Cheapest Fill-Up Today: Shell in Gatineau at 139.6 c/L.
Should You Fill Up Now or Wait?
Montreal: Fill up today to avoid the 2-cent hike.

Why the Variation?
Quebec’s cap-and-trade system and reliance on imported fuel keep prices high.
The switch to summer blends also adds costs, particularly in Montreal.
Atlantic Canada: Stable Prices Across the Board
Atlantic Canada sees no major changes, offering predictability for drivers.
Predicted Gas Prices for Thursday, June 5, 2025
- Halifax, NS: 141.6 c/L (no change)
- Fredericton, Moncton, Saint John, NB: 144.4 c/L (no change)
- St. John’s, NL: 146.7 c/L (no change)
- Charlottetown, PEI: 147.3 c/L (no change)
Analysis
With no price changes forecast, Atlantic Canada remains stable.
Halifax offers the region’s lowest average at 141.6 c/L, while Charlottetown and St. John’s are slightly higher.
The region’s prices are moderate compared to B.C. and Quebec but higher than Alberta and Ontario.
Why the Variation?
Atlantic Canada’s stability reflects consistent regional taxes and less exposure to U.S. refinery fluctuations.
However, higher transportation costs keep prices above Alberta’s.
National Gas Price Trends and Insights
Provincial Averages (June 4, 2025):
- British Columbia: 153.3 c/L

Historical Context
Today’s prices are significantly lower than the peak of 204.3 c/L on June 4, 2022, driven by global oil shortages post-Ukraine invasion.
The 2025 average reflects a more stable market, but potential U.S. tariffs and Middle East volatility could impact future trends.
Key Influences:
Carbon Tax Removal: Saved 11-14 cents per litre in most provinces, except Quebec and B.C., which have their own systems.
Summer Blends: Add 5-10 cents per litre due to lower butane levels, impacting Eastern Canada more.
Global Oil Markets: Stable crude oil prices and reduced demand have kept prices lower than 2022 peaks.
Regional Factors: Proximity to refineries (Alberta) and high taxes (B.C., Quebec) drive local differences.
