La station de métro Longueuil–Université-de-Sherbrooke.
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.
The trip to Berri-UQAM downtown takes about 4 minutes. 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. If you travel only inside the Longueuil agglomeration, the ALL MODES B pass is enough. If you cross to Montreal Island, you need the ALL MODES AB pass.
The monthly pass becomes more economical if you take transit more than 25 times per month.
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 free for ALL MODES AB pass holders. 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 ALL MODES B pass covers travel within Zone B; the ALL MODES AB pass adds Zone A (Montreal Island).
The exact amounts are posted on the ARTM site and revised yearly — check before reloading. Simple rule: if you take transit more than 25 times per month, the monthly pass beats per-trip fares.
Children 11 and under ride free on the RTL and the metro, accompanied by an adult. 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. The B-only pass would block you at the Longueuil-Université-de-Sherbrooke turnstile when transferring to the yellow line. 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?
Yes — for holders of a monthly ALL MODES AB pass. Just present your OPUS card on entry. Without an AB pass, the lot charges a daily fee.
Spaces fill up quickly: arrive before 8 a.m. on weekdays to be sure of getting one. Some commuters drop their car at smaller RTL Park & Rides further from the metro and finish the trip by bus to avoid the rush 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. The cash fare is higher than with an OPUS card, and does not include a transfer to the metro.
For any regular use, the OPUS card pays for itself in the first week. 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?
About 4 minutes on the train itself, plus 3 to 8 minutes of waiting on the platform depending on metro frequency. Platform-to-platform total: 7 to 12 minutes.
Peak frequency on the yellow line is about every 3 to 5 minutes, so you rarely wait long. 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.
