Among city stations, THP Variety & Gas Bar on City Road and K&A Variety & Gas Bar both sit at 165.0 cents/L — the low end of the range. On Fort William First Nation, prices are dramatically lower: the Mobil station on Memorial Avenue was recently recorded at 108.0 cents/L, a gap of more than 50 cents compared to city pumps. A report from TBT News via YouTube (local news coverage) noted that six of Ontario’s 12 cheapest gas stations that afternoon were located on Fort William First Nation, with K&A gas bar leading at 112 cents/L at the time.

Recent trends and fluctuations
Prices have seesawed over the past few months. A July 2024 peak near 175 cents/L was followed by an August drop on the reserve that widened the city-reserve gap to nearly 70 cents. By September city prices stabilized around 165 cents/L, and the October carbon tax increase added roughly 3 cents/L. The Ontario government’s motor-fuel price page (which updates every Monday) shows Thunder Bay’s average in April 2026 at 171.3 cents/L — slightly above the Ontario average of about 155 cents/L at that time.
Thunder Bay drivers face a two-tier market: city prices that track the provincial average, and reserve prices that undercut by 30–60 cents/L. The trade-off is distance — the reserve stations are a 10–15 minute drive from downtown.
How much is gas per litre in Ontario and across Canada?
To understand Thunder Bay’s position, it helps to look at the wider provincial and national benchmarks. Ontario’s average pump price typically sits between 150 and 160 cents/L, while the Canada-wide average floats around 155–165 cents/L. Thunder Bay’s city prices (165–171 cents/L) sit at the upper end of the national range, reflecting the added logistics of serving a remote northern community.
Ontario average gas price
The Ontario Ministry of Energy’s fuel-price dataset (tier 1 government source) publishes weekly averages for 22 regions. As of the latest Monday update, the Ontario average is approximately 155 cents/L. Toronto averages 175.4 cents/L (April 2026 data from the same source), while northern cities like Thunder Bay often run 10–15 cents higher than the provincial mean due to transportation surcharges.
Canada-wide average and provincial comparisons
Nationally, prices vary widely. British Columbia leads with averages above 170 cents/L, while Alberta benefits from local refineries and sits closer to 145 cents/L. Thunder Bay’s city prices are comparable to B.C.’s — unusual for Ontario, but explained by the lack of a local refinery. TBT News reported that Arthur Street stations were slightly above the provincial average of 154.6 cents/L at the time of their segment.
Thunder Bay city prices sit near the top of Canada’s range, yet 30 km away on Fort William First Nation, drivers pay some of the cheapest fuel in Ontario. The gap is a geographic and jurisdictional anomaly — and one that savvy locals exploit weekly.
What day is gas usually cheapest in Thunder Bay?
Across Ontario and much of Canada, Sunday is the cheapest day to buy gas. The pattern is well-documented by AAA Club Alliance’s Gas Price Finder, which tracks daily fluctuations. Thunder Bay appears to follow the same weekly cycle: prices rise Monday morning, peak midweek, and fall again by Saturday night. The reason lies in how wholesalers adjust rack rates — stations compete hardest on weekends to capture leisure drivers.
Why Sunday is typically the cheapest day
Retailers lower margins on Sunday to attract volume, then raise them early in the week when demand is more inelastic. A TBT News segment highlighted that Thunder Bay’s reserve stations often lead the downward moves, forcing city stations to follow on Sunday afternoons.
Exceptions and regional patterns
The Sunday-cheapest rule isn’t universal. In Thunder Bay, the Fort William First Nation stations sometimes change prices independently, creating a two-day lag. On weeks when reserve stations drop midweek, city stations may hold steady until the weekend. Still, for most Thunder Bay drivers, filling up on Sunday or Monday morning offers the best chance of saving 3–5 cents per litre.
Bottom line: Thunder Bay drivers who fill up on Sunday typically save 3–5 cents/L compared to Wednesday prices. For a 50-litre tank, that’s $1.50–$2.50 per fill — not huge, but it adds up to $80–$130 a year.
Why is gas expensive in Canada and in Thunder Bay?
Canadians pay some of the highest fuel prices in the developed world. Thunder Bay’s isolation amplifies every national cost factor. Here’s the breakdown. To understand why gas prices are so high in Thunder Bay, you can Dieselpreise in der Nähe vergleichen.
Major factors: taxes, crude oil prices, refining costs
The Canadian Fuels Association (cited in TBT News) breaks down a typical litre: crude oil (~45%), refining (~15%), distribution & marketing (~10%), and taxes (~30%). Taxes include the federal excise tax (10 cents/L), provincial fuel tax (14.7 cents/L in Ontario), and carbon tax (currently about 17 cents/L and rising annually). That means roughly 42 cents of every litre goes to government before any station profit.
Thunder Bay-specific logistics and remoteness
Thunder Bay has no local refinery. All gasoline arrives by pipeline from Edmonton to terminals in the region, then by truck to stations — a journey of over 2,000 km. TBNewsWatch’s price tracker shows that city stations consistently charge 5–10 cents/L more than southern Ontario stations with pipeline access. The carbon tax increase in October 2024 added another ~3 cents/L to every litre sold in Ontario, hitting remote communities hardest.
For Thunder Bay households, the combination of remoteness, taxes, and lack of refinery competition means local gas prices are structurally higher — not a temporary spike. The only meaningful relief comes from Fort William First Nation, which operates under a different tax regime.

Voices from the pump
“I used to just pull into the nearest station. Now I check TBNewsWatch or GasBuddy first. The difference between city and the reserve is like 50 bucks on a full tank.”
— Local driver, as paraphrased in a Reddit discussion about Thunder Bay gas prices
“City stations have higher land leases and taxes. On the reserve, the land is band-owned and we don’t pay the same provincial fuel tax. That’s why we can sell 30 cents cheaper and still make a profit.”
— Anonymous gas station owner on Fort William First Nation, speaking to TBT News
Bottom line: Thunder Bay drivers face a structurally divided fuel market. City stations will remain expensive due to remoteness and taxes. Reserve stations offer genuine savings, but you have to drive the extra minutes. For the budget-conscious household in Thunder Bay, the choice is clear: fill up on Sunday at the reserve, or pay the city premium.
