The REM, right in the neighbourhood
There's been a train here since 1925, but the old station closed in 2020 for construction. The Sainte-Dorothée station, at 1411 chemin du Bord-de-l'Eau, was inaugurated on November 15, 2025 and reopened to passengers on November 17, this time as a REM station on the Deux-Montagnes branch, between Île-Bigras and Grand-Moulin. It's fully accessible and five Société de transport de Laval bus lines stop there, including routes that connect to the Montmorency and Côte-Vertu metro stations.
