Gatineau's official gas price is the daily average that the Régie de l'énergie du Québec publishes for the region every morning. On October 26, 2026 it was 166.1¢/L for regular gasoline, taxes included, 4.7¢/L below the latest Ottawa survey (October 19, 2026). No wholesale price newer than the survey is available yet, so the estimate for October 27, 2026 repeats 166.1¢/L; the Gatineau series is too recent on this site to measure the method's past error. Because the city sits on the Ontario border, Quebec cuts its fuel tax by 6 cents a litre within 15 km of Ontario, so a Gatineau litre pays 13.2¢/L of provincial tax instead of 19.2 cents, plus GST and QST: 21.0% of the price in all. The Régie survey covers regular only, and no open official source publishes premium or diesel for Gatineau, so this page shows regular gasoline alone.
A border city with a daily price
Gatineau faces Ottawa across the Ottawa River, and the price of a litre on each side is set by two different provincial tax systems. On the Quebec side, the Régie de l'énergie publishes an average every morning, which makes Gatineau's official figure fresher than Ottawa's weekly Ontario survey.
| Fuel | Latest official figure | Date and source | Estimate for October 27, 2026 | Past error of the method |
|---|---|---|---|---|
| Regular gasoline | 166.1¢/L | average of October 26, 2026 · Régie de l’énergie du Québec | 166.1¢/L | not enough surveys yet to measure the error |
The table has a single line because the Régie surveys regular gasoline only and no other open source covers Gatineau. The "past error" column is still empty: the Gatineau series on this site does not yet cover enough days to replay the estimate. The Régie's regional survey keeps the history of previous days.
The 6-cent border reduction
Quebec's fuel tax is 19.2 cents a litre of gasoline in most of the province. Near its borders, the province lowers it so that stations are not left at a disadvantage against their neighbours: within 15 km of Ontario, the reduction is 6 cents. The page applies that band to Gatineau, which leaves 13.2¢/L of Quebec tax in each litre. With GST and QST at a combined 14.975% charged on top, the reduction is worth 6.90¢/L at the pump.
| Component | Per litre |
|---|---|
| Quebec fuel tax | 19.20¢/L |
| Quebec tax reduction near Ontario (0 to 15 km) | -6.00¢/L |
| Federal excise tax | 0.00¢/L |
| Sales tax (GST + QST, 14.975%) | 21.63¢/L |
| Refined product, transport and margins | 131.27¢/L |
| Pump price | 166.1¢/L |
The reduction depends on the distance between a station and the border, so a station well inside the province can be taxed differently from one close to the river. The federal excise tax, suspended since April 20, 2026, is the same on both banks; the tax page has its planned return in 2027.
Gatineau and Ottawa, litre for litre
At their latest official figures, tax takes 34.8¢/L of a Gatineau litre and 28.6¢/L of an Ottawa litre. Ontario charges 9 cents of gasoline tax and 13% HST; Quebec, even after the border reduction, charges more per litre and a higher sales tax. Whatever is left between the two pump prices after that is the product and the retail margin.
Gatineau against Ottawa
Difference per litre, Ottawa minus Gatineau
+4.7¢
| Gatineau | 166.1¢/L (average of October 26, 2026) |
| Ottawa | 170.8¢/L (survey of Monday, October 19, 2026) |
| On a 55 L fill-up | $2.59 |
| Over 15,000 km a year | $61 |
Keep the dates in mind when reading the result: the Gatineau figure is from this morning, the Ottawa one from the Monday survey. Ottawa's own estimate for tomorrow uses the Régie's daily Montreal figure as its market signal, which is shown on the Ottawa page.
