Preparatory work on the Deux Montagnes line

Public transit  | Major
Starting April 27, 2018, weekends from Friday night (8 p.m.) through Sunday
North Shore

Work required in preparation for the future REM infrastructure will begin April 27th. This important step will provide critical data that will help to guide NouvLR, the consortium entrusted with the REM’s construction, in designing the REM structures and stations.


Nature of the work

Coordinated by the REM project office, the work will initially consist in geotechnical drilling, surveying and the building of temporary facilities. These tasks are critical to assessing soil composition and resistance — a prerequisite to designing and constructing the various infrastructures.



In progress: Beginning of construction of McGill, Édouard-Montpetit, Canora and Mont-Royal stations and of the Saint-Eustache maintenance centre. There is currently no service on Friday nights and weekends on the Deux-Montagnes and Mascouche lines.

Upcoming work:

  • March 25, 2019: Update of schedules for the Deux-Montagnes and Mascouche lines (more information)
  • May 21, 2019: Implementation of a shared platform for the Canora and Mont-Royal stations (more information)
  • January 2020 to early 2022: Closure of the Central Station Centrale–Du Ruisseau segment – the Deux-Montagnes line stops at Bois-Franc, while the Mascouche line stops at Ahuntsic
  • Mid-2021 to end 2023: Complete closure of the Deux-Montagnes line
  • Early 2022: Commissioning of the REM at Du Ruisseau
