The Exo (public transit) Le Richelain sector is the public transportation system for the municipalities of La Prairie, Candiac and Saint-Philippe, which are suburbs lying southeast of Montreal in Quebec, Canada. Originally the communities around Saint-Jean-sur-Richelieu were included but the town now has its own public transit system which serves that area. The sector merged with the Exo Roussillon sector when the Réseau express métropolitain opened on July 31, 2023.
Commuter service to Montreal is the major function of the sector, either directly to Terminus Centre-Ville via a reserved bus lane on the Champlain Bridge or services to Terminus Longueuil with a connection to the metro towards downtown Montreal.
In 2018, exo awarded Transdev the contract to run service for the sector. The Contract start date was January 1st, 2019 and runs till June 30th, 2024 with a 3-year option for exo to extend the contract till June 30th, 2027.
