1. The RTL — your local network
The RTL, or Réseau de transport de Longueuil, is the bus operator for the Longueuil agglomeration.
It serves Longueuil, Brossard, Saint-Lambert, Boucherville and Saint-Bruno-de-Montarville. More than 80 routes cover the territory, with high frequency at rush hour.
2. The metro yellow line
Montreal's metro yellow line crosses the river and ends at Longueuil–Université-de-Sherbrooke station. It is the only direct metro access from the South Shore.
Without any transfer, it takes you to Berri-UQAM downtown. Dozens of RTL routes converge on this station, which is also a major bus terminus.
3. OPUS card and fare zones
Greater Montreal is divided into fare zones managed by the ARTM.
Longueuil is in Zone B, and so is the Longueuil–Université-de-Sherbrooke metro station. If you travel only by bus inside the Longueuil agglomeration, the Bus fare is enough. As soon as you take the metro, or cross to Montreal Island, you need the ALL MODES AB pass: there is no ALL MODES B pass.
According to the ARTM fare schedule, the monthly AB pass becomes more economical if you take transit more than 34 times per month (fares in effect July 1, 2026: single AB fare $5.00, monthly AB pass $170).
4. Where to get and reload your OPUS card
You can buy an OPUS card at the ticketing machines in Longueuil-Université-de-Sherbrooke station, or at the RTL service point.
Reloading works at the same places, at participating pharmacies and convenience stores, or online via the ARTM site. The photo OPUS card is required for reduced fares.
5. Park and Ride
If you live further out and drive to the metro, the large Park & Ride at Longueuil-Université-de-Sherbrooke is not free, even with an ALL MODES AB pass — it's a paid service run by a third-party operator, Stat Park. Spots fill up quickly — arrive before 8 a.m. to be sure of getting a space.
6. RTL and ARTM fares at a glance
Fares are set by the ARTM for all of Greater Montreal and apply to both the RTL and the metro. The Bus fare covers bus travel within Zone B (as well as Zones A and C); the ALL MODES AB pass covers every mode, metro included, in Zones A and B.
The exact amounts are posted on the ARTM site and revised yearly — check before reloading. Simple rule: if you take transit more than 34 times per month (fares in effect July 1, 2026: single AB fare $5.00, monthly AB pass $170), the monthly AB pass beats per-trip fares.
Children 11 and under ride free on the RTL and the metro, accompanied by a person aged 14 or older. The photo OPUS card is required for all reduced fares — students, persons 65 and over, and holders of certain social programs.

7. Frequently asked questions
The most common questions from new Longueuil residents about the RTL, the yellow metro line and the OPUS card: which pass to choose, how the Park & Ride works, whether OPUS and cash can be combined, and how long Berri-UQAM takes at rush hour.
Which OPUS pass should I pick if I work in Montreal but live in Longueuil?
The ALL MODES AB monthly pass. It covers both Zone A — Montreal Island, metro included — and Zone B — the Longueuil agglomeration.
It is the standard commuter pass for daily Rive-Sud-to-island trips. A Bus fare does not give access to the metro, and there is no ALL MODES B pass: at the Longueuil-Université-de-Sherbrooke turnstile, you need an ALL MODES AB pass. Buy it on the photo OPUS card if you also qualify for a reduced rate as a student or 65+.
Is the Longueuil Park & Ride really free?
No — it's not free, even with a monthly pass. The Longueuil Park & Ride is a paid parking service (run by a third-party operator, Stat Park), separate from your ARTM transit fare. Holding an ALL MODES AB pass does not waive the parking fee.
Rates change periodically — confirm the current daily and monthly parking rates directly with the operator before relying on this lot. Spaces fill up quickly regardless: arrive before 8 a.m. on weekdays. Some commuters use smaller RTL Park & Rides further from the metro and finish the trip by bus to avoid both the crowd and the cost at the main lot.
Can you pay cash on an RTL bus?
Yes. The driver accepts cash for a single trip, but does not make change — bring exact coins. According to the ARTM fare schedule, a cash fare on the bus costs $3.75 within or between zones A and B, the same price as a Bus single fare; it does not give access to the metro.
The ARTM advises buying your fare on an OPUS card before your trip to get a lower fare; if you travel often, a monthly pass costs less (see section 3). The card itself is a one-time purchase valid for several years; only loaded amounts and monthly passes are recurring.
How long does Longueuil to Berri-UQAM take at rush hour?
The ride on the train itself is short; add your wait on the platform. According to the STM's posted frequencies for this station, on weekdays a train leaves Longueuil every 4 to 5 minutes at peak times (7 to 9 a.m. and 4 to 6 p.m.) and every 4 to 10 minutes off-peak; on weekends, every 5 to 10 minutes.
At rush hour, you rarely wait more than 5 minutes. Add walking time at each end. The yellow line is a single segment with one intermediate station — Jean-Drapeau on Île Sainte-Hélène — so no transfers and no surprises.
