How to find the cheapest STM pass in Montreal (2026)
Réponse rapide : If you make more than 26 one-way trips per month on the STM, the monthly OPUS pass ($103 for adults in 2026) is almost always your cheapest option. Below 18 trips, the 10-trip pack wins. Use the calculator above to confirm based on your actual usage.

The breakpoints you actually need to remember
The Montreal transit pricing math has three useful tipping points:
- Under 9 trips per month: pay per ride. Loading a 10-pack you won’t finish ties up your money.
- 9–26 trips per month: the 10-trip pack at $33 is the sweet spot. Two packs equal one monthly pass but only if you actually use all 20.
- 27+ trips per month: get the monthly OPUS pass. Below-30 commuters often think they don’t need it — the calculator above proves otherwise.
Hidden ways to save more on STM fares
Three tricks Montrealers use that aren’t obvious:
- Free transfer window: One paid fare gives you 120 minutes of metro + bus connections. Plan errands in a single 2-hour block to avoid double fares.
- Evening pass for weekend nights: If you only ride after 6pm on Fri/Sat, the $6.50 evening pass beats two single fares.
- Children under 12 ride free with a paying adult on weekends and holidays — no OPUS card needed.
OPUS card vs. contactless: what changed
As of 2026, the STM accepts credit cards and mobile wallets (Apple Pay, Google Pay) on most metro turnstiles and buses. For occasional riders this is more convenient. For monthly riders the OPUS card is still cheaper because contactless pay-per-ride doesn’t include the 10-trip discount.
STM Fare FAQ
How much does the STM monthly pass cost in 2026?
The adult monthly OPUS pass for Zone A (Island of Montreal) is $103.00 CAD. The reduced pass (ages 6–17, 65+, full-time students with valid OPUS photo card) is $62.00. Zone AB, which includes Laval and Longueuil, costs $172.50 for adults.
What’s the difference between Zone A and Zone AB?
Zone A covers all STM service on the Island of Montreal — metro and buses. Zone AB adds the Laval metro stations (Cartier, De la Concorde, Montmorency), Longueuil-Université-de-Sherbrooke, and most regional buses to those cities. If you live in Montreal and never cross to Laval or the South Shore, Zone A is all you need.
Is the STM evening pass worth it?
Yes, if you only travel between 6pm and 5am and make at least 2 trips. At $6.50 for unlimited evening rides, it beats two singles ($7.50). It also covers all weekend evenings — useful for nightlife in the Plateau or Mile End without paying $3.75 each way.
Can I use Apple Pay on the STM metro?
Yes, since 2024 the STM accepts Apple Pay, Google Pay, and contactless credit cards at metro turnstiles and on buses. However, contactless pay-per-ride charges single-fare prices ($3.75) — no discounts. Frequent riders still save with an OPUS card.
Do STM passes work on EXO commuter trains?
No. EXO (the regional commuter train network) uses a separate ARTM fare system. You need a TRAM pass or a regional fare for commuter trains. The STM monthly only works on STM buses and metro within Zone A or AB.
What’s the cheapest way to get from Pierre Elliott Trudeau Airport (YUL) to downtown?
The 747 Express Bus costs $11.00 for a single ticket (or free with a valid weekly/monthly OPUS pass). It runs 24/7 and takes 45–60 minutes to Berri-UQAM. Cheaper than the average $50 taxi to downtown.
When does the STM raise fares?
STM and ARTM typically announce annual fare increases in December, effective January 1st of the new year. Increases over the past five years have ranged from 2% to 4%. The 2026 rates above took effect January 1, 2026.
