The bus network in Chambly-Richelieu-Carignan has been transformed to align with the REM on the South Shore and improve travel between regions. This new network is the result of consultations with users, citizens and local communities.
4 changes in 2023
The launch of the new bus network is scheduled for spring 2023, to coincide with the opening of the REM. From this date forward, buses that used to cross the Samuel-De 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.
New bus routes
Eight direct routes will provide users with quick access to the REM's Brossard Station. New routes will also facilitate travel between municipalities and towards major South Shore hubs:
New route numbers
Bus and taxibus route numbers will also be changing. The new numbering system is organized according to 4 types of service:
Local - n˚ 20 to 299
Local routes operating mainly within the sector
Upon reservation - n˚ 300 to 399
Routes operating upon reservation only
Express - n˚ 400 to 699
Lines running mainly during peak hours, to a metro, terminus or other major destinations
Regional - n˚ 600 to 799
Routes connecting several municipalities

New transit fares
Since July 2021, the ARTM’s fare reform has divided the metropolitan area into four large fare zones. All municipalities in Chambly-Richelieu-Carignan are now located in Zone C, with the exception of Marieville which is located in Zone D. New transit fares have been available since 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. Starting in spring 2023, 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 Samuel-De 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.
In October, CDPQ Infra announced the target date for the opening of the REM: spring 2023. The precise date will be shared approximately one month in advance.
An information campaign and activities will be deployed at this time to guide our customers through these significant changes.
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 eight 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 Samuel-De 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 Chambly-Richelieu-Carignan with downtown Montreal via the Samuel-De 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 required to access the REM.
Yes! The new bus network offers better cross-suburb service, and 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.
The preliminary estimated travel times to the REM are as follows:*

The last departures from Brossard bus terminal are scheduled at 1:10 a.m. on weekdays and 1:03 a.m. on Saturdays and Sundays.
Trip planners (Chrono, Transit, Google) will be available one month before the new network opens.
Several stops will remain unchanged, while new stops will be added and others removed.
Our buses serve some 60 municipalities on Montreal’s North and South Shores, most of which are located in the Montreal Metropolitan Area. However, some municipalities are outside of this territory, such as Saint-Jean-sur-Richelieu, which has its own bus network.
Exo does not have the power to modify its coverage area. This is the responsibility of the Autorité régionale de transport métropolitain (ARTM), which is in charge of public transit planning, financing and fare pricing in the metropolitan area.
However, the new exo network will continue to serve the cegep and hospital in Saint-Jean-sur-Richelieu, as is currently the case.
No, the new Route 486 serving Richelieu and Marieville will stop at the REM's Brossard station.
According to an agreement between the Autorité régionale de transport métropolitain (ARTM) and the Caisse de dépôt et placement du Québec Infra (CDPQ Infra), as soon as the REM opens, exo and RTL buses will no longer have access to the Samuel-De Champlain Bridge.
