Gasoline prices across Quebec can feel like they belong to different markets, and Sunday’s numbers put a striking figure on that divide. A live October 25 snapshot based on Régie de l’énergie data showed regular gasoline averaging 160.9 cents per litre in Saguenay–Lac-Saint-Jean and 204.8 cents in Nord-du-Québec at 12:55 p.m. That works out to a regional gap of 43.9 cents per litre.
The province-wide average at the same point was 183.6 cents per litre, down slightly from the previous day and 5.4 cents lower than a week earlier. In other words, Quebec’s overall price trend was easing even as geography continued to produce dramatically different bills at the pump. For motorists, the Sunday snapshot is a reminder that a provincial average can hide as much as it reveals.
A 43.9-Cent Regional Gap Adds Up Quickly
A 43.9-cent difference may sound abstract until it is translated into a fill-up. At Sunday’s reported regional averages, buying 50 litres in Saguenay–Lac-Saint-Jean would cost about $80.45, while the same 50 litres at the Nord-du-Québec average would cost about $102.40. The difference is $21.95 on one tank. For a household filling twice a month, a gap of that size would amount to more than $500 over a year if it persisted, although fuel prices rarely remain fixed for that long.
The contrast is also large relative to the provincial average. Saguenay–Lac-Saint-Jean was roughly 22.7 cents per litre below Quebec’s 183.6-cent live average, while Nord-du-Québec was about 21.2 cents above it. That symmetry makes the province-wide figure look deceptively ordinary: drivers at opposite ends of the map were experiencing very different prices at the same time. The Sunday data therefore says less about a single “Quebec gas price” than it does about several regional fuel markets operating under different local conditions.
Saguenay–Lac-Saint-Jean Is the Low-Price Outlier
Saguenay–Lac-Saint-Jean stood out as Quebec’s low-price region on Sunday. In a later live snapshot that afternoon, the region was still averaging about 160.8 cents per litre, with reported station prices ranging from 155.6 to 188.9 cents. Outaouais, the next-lowest regional average in that snapshot, was around 171.5 cents per litre. That left Saguenay–Lac-Saint-Jean more than 10 cents below another relatively inexpensive region and more than 20 cents below the provincial average.
The live numbers alone do not prove why Saguenay–Lac-Saint-Jean was so cheap that day. CAA-Quebec notes that local pump prices can vary with retail margins, the level of competition, the type of service station and sales volumes, while wholesale and refining influences are shared more broadly. Those factors can create sharp local price cycles even when the underlying commodity is the same. The safest conclusion is that Saguenay–Lac-Saint-Jean was a genuine low-price outlier on October 25, not that any single tax, company or market practice caused the entire discount.
Nord-du-Québec Sits at the Other Extreme
Nord-du-Québec occupied the other end of the Sunday table. The regional average was 204.8 cents per litre, and the afternoon station data showed reported regular-gas prices ranging from roughly 189.4 to 239.3 cents. That upper end was not just high compared with Saguenay–Lac-Saint-Jean; it was more than 55 cents above the province-wide average. The region also had far fewer stations represented in the live table than southern regions, making individual high-priced outlets more influential on the regional average.
Geography is an important part of the explanation. The Régie de l’énergie says transportation costs vary from one city to another and that service stations farther from fuel depots face higher delivery costs. CAA-Quebec likewise identifies transport, retail margins, competition and sales volume as factors that can differ by region. There is another statistical caution: Quebec’s real-time reporting rules exempt certain low-volume stations and outlets north of the 55th parallel from the mandatory publication requirement. The Nord-du-Québec figure is therefore best read as the average of reported stations in the live system, not a claim that every station across the enormous region was charging the same amount.
Taxes Affect the Map, but They Do Not Explain It All
Taxes shape Quebec’s fuel-price map, but they cannot by themselves explain a 43.9-cent regional gap. Revenu Québec lists the regular provincial gasoline tax at 19.2 cents per litre in most areas, while also allowing higher or lower rates in designated territories. In the Autorité régionale de transport métropolitain territory, an additional gasoline levy supports public transit; the ARTM’s 2026 budget identifies that dedicated amount as three cents per litre. GST and QST are applied on fuel as well.
Those differences matter, yet the province deliberately reduces fuel-tax rates in some border and other designated regions, recognizing that location can affect the cost of getting fuel to market. The remaining spread comes from the commercial side of the equation: the rack price, transportation, local retail margins and competitive conditions. CAA-Quebec explains that the refining margin is common across Quebec’s administrative regions, while retail margins and transport costs can vary locally. That helps explain why two regions can share the same broad oil-market backdrop but still post very different pump prices on the same Sunday.
Quebec Prices Were Falling Even as Regional Gaps Stayed Wide
The regional divide arrived during a period when Quebec gasoline prices were generally moving lower. At 12:55 p.m. Sunday, the live provincial average of 183.6 cents per litre was 0.2 cents below the previous day and 5.4 cents below the level seven days earlier. A separate daily series built from Régie data showed a similar direction, with the Quebec average falling from roughly 194.7 cents per litre on October 9 to the mid-184-cent range by October 25. The exact average can differ slightly depending on the time of the snapshot and calculation method, but the trend was clearly downward.
That distinction matters for anyone seeing the 43-cent headline and assuming prices were suddenly surging everywhere. They were not. The Sunday story was about dispersion, not a province-wide spike. A driver in a low-price market could be paying materially less than a week earlier, while a driver in a remote or high-cost market could still face a price above two dollars per litre. Provincial averages are useful for tracking direction over time, but regional and station-level data are far more relevant to what households actually pay on a given day.
The Station-to-Station Spread Is Even Larger
The gap between the cheapest and most expensive individual stations was almost twice as large as the gap between regional averages. Sunday’s live data showed regular gasoline as low as 155.6 cents per litre and as high as 239.3 cents, an 83.7-cent spread across the reported Quebec stations. On a 50-litre fill, that difference is $41.85. It is an extreme comparison rather than a typical shopping opportunity, but it demonstrates how much variation can sit underneath a single provincial number.
Quebec’s retail structure helps explain why prices can cluster or move in waves. In the Régie de l’énergie’s latest retail-market portrait, based on the network operating at the end of 2024, nearly two-thirds of service stations were linked to a price centre that directed the price to display, and more than three-quarters of gasoline and diesel volume was sold at prices determined by a price centre. At the same time, CAA-Quebec says competition, station type and sales volume still affect local pricing. The result is a market where prices can move together in one area yet remain dramatically different from another.
Real-Time Reporting Changes How Drivers Can Shop for Fuel
Quebec drivers now have more direct access to those differences than they did a year ago. The Régie de l’énergie launched its Régie essence Québec platform on April 1, 2026, giving the public a map of reported prices across roughly 2,500 stations. Covered retailers must update their posted gasoline and diesel prices whenever they change, and the Régie says updates should flow to the public map within a maximum of five minutes. The platform includes regular gasoline, premium gasoline and diesel, and displayed prices include the applicable taxes.
That makes regional price gaps more actionable, but the biggest number on a map is not automatically a reason to drive across town. A 10-cent-per-litre difference saves $4.50 on a 45-litre fill; a long detour can quickly consume part of that saving in fuel and time. The practical value of real-time reporting is in spotting meaningful nearby differences and avoiding an unnecessarily expensive station when alternatives are already on the route. Sunday’s 43.9-cent regional divide is striking, but for most motorists the more useful comparison is the handful of stations they can realistically choose among before the next fill-up.
