Le Richelain and Roussillon

The Le Richelain and Roussillon sectors have been combined to better harmonize our services. The result of consultations with users, citizens and local communities, the new bus network aligns with the REM and improves travel between regions.

4 changes in 2022

The launch of the new bus network is scheduled for fall 2022, to coincide with the opening of the REM. From this date forward, buses that used to cross the Champlain bridge will now take passengers to one of the REM stations in Brossard, where users can travel on to Downtown Montreal or transfer towards other destinations on the South Shore.

  1. New bus routes

    Fourteen direct routes will provide users with quick access to the REM. New routes will also facilitate travel between municipalities and towards major South Shore hubs:

    • Longueuil–Université-de-Sherbrooke metro station

    • Candiac, Sainte-Catherine, Saint-Constant and Delson train stations

    • Quartier DIX30 and Champlain Mall

    • Businesses on Taschereau Blvd. and the R-132

    • Kateri CLSC

    • Industrial areas in Delson, Champlain-Candiac, La Prairie and Sainte-Catherine

  2. New route numbers

    Bus and taxibus route numbers will also be changing. The new numbering system is organized according to four types of service:

    • nos. 20 to 299

      Local routes operating within the sector only

    • nos. 300 to 399

      Routes operating upon reservation only

    • nos. 400 to 599

      High-frequency routes serving a metro, terminal or the REM, operating mainly during peak periods

    • nos. 600 to 799

      Routes connecting several municipalities

  3. New transit fares

    Since July 2021, the ARTM’s fare reform has divided the metropolitan area into four large fare zones. All municipalities in the Le Richelain and Roussillon sectors are now located in Zone C. New transit fares will be available as of July 1, 2022, to meet your travel needs.

Frequently asked questions

We prioritized the review of our network in these sectors in order to align our services with the launch of the Réseau express métropolitain (REM) on the South Shore. In fall 2022, the REM’s South Shore segment will link Montreal’s Central Station to three stations on the South Shore. From this date forward, buses that used to cross the Champlain bridge will now take passengers to one of the REM stations, where they can travel on to Downtown Montreal or transfer towards other destinations on the South Shore.

Users can enjoy a region that is better connected, notably thanks to simpler transfers to other exo sectors and Réseau de transport de longueuil (RTL) services. As well, more citizens will now be within walking distance of a bus stop. The new bus network is also perfectly aligned with the REM, with 14 high-frequency routes that directly serve its stations. Service to commercial and industrial hubs has also been improved, during both peak and off-peak periods.

As soon as the REM opens on the South Shore, our buses will no longer have access to the Champlain bridge. To get to Montreal, you may use our bus services to connect with the REM, which can then take you to several Montreal destinations. Certain bus routes will continue to serve major hubs in Longueuil (metro) and Montreal via the Mercier bridge.

Also note that this situation has allowed exo to add more local routes as well as routes that facilitate cross-suburb travel.

The routes that link Le Richelain and Roussillon with Downtown Montreal via the Champlain bridge have been modified in order to serve South Shore REM stations directly when they open. As much as possible, local service has been configured in order to limit the transfers necessary to get to the REM.

Yes! The new bus network will improve east-west service. We’re planning to better align our services with those of the Réseau de transport de longueuil (RTL) in order to facilitate travel between regions. The new REM terminals will be privileged areas for transfers between the two networks.

Yes, boarding and disembarking outside the territory we serve as well as transfers with the REM, STM and RTL are permitted, depending on your fare. To board an exo bus and travel into RTL or STM territory, you must hold a valid transit fare.
