Réseau express métropolitain

A new line that
transports Greater Montréal



Once completed, the REM will be one of the largest automated transportation system in the world after Singapore, Dubai  and Vancouver. For the metropolitan area, the REM also represents the largest public transportation infrastructure since the Montréal metro, inaugurated in 1966. 

The solution proposed by CDPQ Infra will:

  • offer an integrated, efficient and reliable service
  • constitute Québec’s first “public-public” partnership project
  • build a new network of strategic importance for the Montreal metropolitan area and for Québec
  • foster environmentally sustainable transportation

Integrated, efficient and reliable service

As a single, integrated transportation network, the REM will offer a number of efficient travel options in the Greater Montréal area. The REM will be connected with bus networks, commuter trains (Mascouche and Saint-Hilaire lines) and with the Montréal metro (Blue, Green and Orange lines).

With frequent and reliable service – 20 hours a day, every day – the REM represents a new paradigm and significant time savings for commuters in the metropolitan region. The decision to use dedicated tracks will allow for quick and uninterrupted travel, and passengers will have Wi-Fi connectivity and access to live status updates.

Construction costs and benefits

The REM represents construction costs of approximately $6.3 billion. 

Main financing sources

  • La Caisse: $2.95 billion
  • Gouvernment of Québec: $1.28 billion
  • Gouvernment of Canada: $1.28 billion

Potential economic benefits

  • GDP: the REM could potentially add more than $3.7 billion to Québec’s GDP over four year
  • Real estate developments: close to $5 billion in private real estate developments along the route are currently expected
  • Jobs: more than 34,000 direct and indirect jobs will be created during the construction phase and more than 1,000 permanent jobs will be created once the REM starts running
  • Environment: the REM could help reduce GHG emissions by by 680,000 tonnes over 25 years of operation and accelerate Québec’s transition to a low-carbon economy
  • Traffic congestion: this new public transit system could reduce economic losses associated with traffic congestion, currently estimated at $1.9 billion annually in the Greater Montréal area

Sustainable mobility services

Agreements have been reached with various sustainable mobility services (Bixi, Car2go, Communauto, Netlift, Téo Taxi, Vélo Québec) to offer passengers a variety of travel options between home and the station. For additional options, mobility services around REM stations will combine car-sharing, carpooling and electric taxi services.
