Gas prices in Montréal: keep language, grade and geography aligned

Montréal drivers have two things most Canadians don’t: a government-run map of station-by-station pump prices, and an extra regional fuel tax that covers the whole metro area, not just the island. We don’t show live prices. This page explains what goes into a Montréal litre, where to find the official price map, and how to compare English and French results without counting the same station twice.

What’s in the price at a Montréal pump

Quebec stacks more on a litre of gasoline than the Prairie provinces do. As of November 2026:

Quebec fuel tax: 19.2¢ per litre on gasoline (CAA-Québec; Revenu Québec rate page; NRCan).
Greater Montréal transit tax: 3¢ per litre on gasoline, collected by Quebec and passed to the Autorité régionale de transport métropolitain (ARTM) to help fund public transit (CAA-Québec). Revenu Québec publishes the list of municipalities in the ARTM territory where the higher rate applies.
Cap-and-trade, not a carbon tax line. The federal fuel charge never applied in Quebec (Finance Canada lists the provinces it covered), so its April 2025 removal didn’t change Montréal prices. Instead, Quebec’s Cap-and-Trade System has covered fuel distributors since 2015 (Quebec Environment Ministry). There’s no posted cents-per-litre rate for it: it works through the emission allowances distributors must hold, so whatever it costs sits inside the pump price rather than appearing as a separate line. NRCan notes Quebec is now the only province where carbon pricing still reaches fuel (NRCan).
Federal excise tax: 0¢ until 31 January 2027. The 10¢/L tax was suspended on 20 April 2026; it returns at 5¢/L on 1 February 2027 and 10¢/L on 1 April 2027 (Finance Canada).
GST 5% and QST 9.975% (CRA rate table), charged on top of the fuel taxes. CAA-Québec’s phrase for it is “taxes are taxed”.

Why the 3¢ matters less than you’d think

The ARTM tax isn’t an island tax. It covers Greater Montréal, including Laval and the Longueuil area, so crossing a bridge to Laval or the South Shore doesn’t get you out of it. Escaping it means driving to a municipality outside the ARTM territory, and for most Montrealers that’s a long way to save 3¢ a litre. The worked example below puts numbers on it.

Quebec’s official station price map

Since 1 April 2026, Quebec fuel retailers have had to enter the prices they charge consumers for each of their stations into a Régie de l’énergie portal, and those prices are public on Régie essence Québec (Régie de l’énergie user guide, PDF). Small sellers (under 500,000 litres a year), stations north of the 55th parallel and a few specialised outlets are exempt (Régie de l’énergie).

At launch, the map covered about 2,200 stations, let you filter by régulier, super and diesel, offered a “Signaler une inexactitude” (report an error) button for each station, and allowed the data to be downloaded as an Excel file (Le Manic, 1 April 2026). The site is in French.

For context rather than a stop decision, the Régie also publishes daily and weekly average prices for regular gasoline (essence ordinaire) by region, with Montréal split into six areas: centre-est, centre-ouest, est, nord, ouest and sud de l’île (Régie de l’énergie price survey).

Keep language, grade and geography aligned

A Montréal search mixes English and French pages, crowd-reported apps and the official map. Three habits keep the comparison honest:

Grade: regular may appear as “ordinaire” or “régulier” in French, and premium as “super”. Make sure you’re comparing the same one.
Geography: “Montréal” on one site may mean the island; on another, the whole metro area. Check the municipality in each address.
Duplicates: the same station can show up under an English and a French name, or on two sites. Match the street address before counting it twice.

Using GasBuddy Montreal results

Whether you type GasBuddy Montreal or Montréal, it’s the same search area; pick the neighbourhood or postal code you’ll actually drive from.
Choose your grade, then check how old each report is.
Cross-check a promising price against the station’s entry on Régie essence Québec, which comes from the retailer rather than from other drivers.
If the two disagree, trust the more recent one and confirm at the pump. Use the Régie’s error button if the official listing is wrong.
For current crowd reports, start on the official GasBuddy website or app.

What Montréal search results show

The Montréal results include an English-language city price page that identifies a source and update date. See the referenced page. Checked 4 November 2026; recheck the page before relying on it.

Montréal worked example: is leaving the ARTM area worth it?

The figures are hypothetical, chosen to illustrate the arithmetic, not quoted Montréal prices. Suppose a station outside the ARTM territory is 3 cents per litre cheaper (just the transit tax), you buy 40 litres, and getting there and back adds 30 km.

Item	Calculation	Result
Gross saving	40 × 3/100	C$1.20
Extra driving fuel cost	30 extra km × 8 L/100 km ÷ 100 × C$1.70 per litre	C$4.08
Net saving before time and other costs	Gross saving − extra fuel	−C$2.88

You’d lose almost three dollars, before counting bridge traffic. The transit tax only works in your favour if you’re already driving out of the region and fill up on the way. Run your own trip in the trip fuel cost calculator.

Are gas prices cheaper on the West Island?

The West Island is on the island of Montréal, so it carries the same 3¢ ARTM tax as downtown. Any gap comes from individual stations, not taxes. The Régie’s average for “ouest de l’île” against other Montréal areas is a quick way to check.

Should Montreal and Montréal have separate pages?

No. They’re two spellings of one city, and this one guide covers both.
