Exo, officially known as Réseau de transport métropolitain (RTM; English: Metropolitan Transportation Network), is a public transport system in Greater Montreal, including the Island of Montreal, Laval (Île Jésus), and communities along both the North Shore of the Mille-Îles River and the South Shore of the St. Lawrence River. It was created on June 1, 2017, taking over from the Agence métropolitaine de transport. The RTM operates Montreal's commuter rail and metropolitan bus services, and is the second busiest such system in Canada after Toronto's GO Transit. In May 2018, the former Réseau de transport métropolitain (RTM) was branded as Exo.

Exo's territory is concurrent with Montreal Metropolitan Community limits, with the addition of the Kahnawake First Nations reserve and the city of Saint-Jérôme.

It serves a population of approximately 4.1 million people who make more than 174,000 trips daily in the 4,258.97 km2 (1,644.40 sq mi) area radiating from Montreal.

Exo's mandate includes the operation of Montreal's commuter rail service, which links the downtown core with communities as far west as Hudson, as far east as Mont-Saint-Hilaire, as far south as Candiac, as far north as Saint-Jérôme, and commuter buses formerly run by local operators.

Partners in transport

Exo's parent agency, the Autorité régionale de transport métropolitain (ARTM), is charged with transportation planning for the Greater Montreal area.

Exo operates commuter train service as well as the bus service outside of the three main population centres of Greater Montreal. In these areas service is provided by the Société de Transport de Montréal on the Island of Montreal, the Société de Transport de Laval in Laval, and the Réseau de transport de Longueuil for the urban agglomeration of Longueuil.

Commuter rail

Exo's commuter trains are its highest-profile division. It uses diesel-electric push-pull trains. The Mont-Saint-Hilaire and Mascouche lines run on Canadian National trackage and operate out of Central Station, while the Vaudreuil-Hudson, Saint-Jérôme, and Candiac lines run on Canadian Pacific Kansas City (CPKC) trackage and operate out of Lucien L'Allier terminus, beside the historic Windsor Station. The Saint-Jérôme line also runs on CPKC trackage and on Exo's own trackage between Sainte-Thérèse and Saint-Jérôme.

Operation of all commuter rail was provided by contract to CN and CP (on their respective rail networks) until June 30, 2017. Operations were taken over by Bombardier Transportation beginning July 1, 2017, on an 8-year contract.

The train lines are integrated with the bus and Metro network maintained by the Société de transport de Montréal (STM).

As of July 1, 2022, the Autorité régionale de transport métropolitain (ARTM) which is responsible for the distribution of fares in the Greater Montreal area has designated 4 zones on its territory A, B, C and D. The Island of Montreal is under zone A. Laval and Longueuil are part of zone B. The northern and southern suburbs of Montreal (off-island) are part of zone C. Zone D is territory not under the authority of the ARTM but it is still responsible for the distribution of fares there as well. 

If a trip starts and ends on the island of Montreal, an all modes zone A fare is required. This includes all modes of public transit (i.e. bus, Metro, REM or Exo). If a trip leaves zone A (Montreal) then a fare for the corresponding zone is required. For example, a trip between Montreal and Laval will require an all modes AB fare. Fares are valid for 120 minutes after the first validation. There are no fare gates; instead, a proof-of-payment system is used, where fare inspectors randomly check tickets

All fares are available in a cheaper "reduced" category for children 6 to 17 years old, and seniors that are 65 or older. Additionally, monthly passes are available in a "student" category (which is cheaper than the regular fare but more than the reduced fare) for students 18 to 25 years old. To benefit from the reduced or student fares, the passenger must have a reduced-fare OPUS card with their name and photo on it. Travel on the commuter trains is free for anyone 5 and under as well as children 6 to 11 years old travelling with an adult.

Following the introduction of the OPUS, smart card system tickets and passes are now sold by automated vending machines at each station. The machines accept cash, credit and debit cards. Purchases of more than $80 must be paid by cards. Tickets and passes are also sold at a few stores near the suburban stations. Consult the full list on the RTM's website. Passes are valid for a calendar month, and are normally on sale from the 20th of the previous month to the 5th of their month of validity. Passengers can also subscribe to OPUS+ which automatically debits the passenger's bank account or credit card and adds the pass to the passenger's OPUS card.


Rolling stock

Exo has a variety of rolling stock, some of it acquired from GO Transit, the rest built specifically for it. There are a total of 256 cars and locomotives in the fleet.

Passenger cars

Current push-pull train coaches

  • 160 Bombardier MultiLevel Coaches (3000 series cars), built between 2009 and 2011.
  • 22 Bombardier BiLevel Coaches (2000 series cars), including 4 cab cars, built in 2004.


Future coaches

  • In June 2017, the RTM ordered 24 bi-level coaches from CRRC Tangshan, with deliveries expected by 2020. In April 2019, the agency ordered an additional 20 coaches.
  • In March 2018, the RTM announced that it would purchase another 20 2000 series cars.


Retired coaches

  • 24 single-level coaches (700 series cars); Built in 1989 by Bombardier Transportation and renovated in 2011-2013. Retired in 2022 following the delivery of new coaches.
  • 80 single-level coaches (originally from GO Transit); Built between 1967 and 1976 by Hawker-Siddeley Canada; retired following the arrival of the 160 multi-level cars.
  • 9 Canadian Vickers gallery cars (rebuilt from June 2005 to December 2006).
  • 58 Bombardier MR-90 electric multiple units used exclusively on the Deux-Montagnes line. Withdrawn in December 2020 due to the construction of the Réseau express métropolitain.

The 22 bilevel coaches are in operation on the Saint-Jérôme line. The AMT did not purchase additional bilevels as it sought to standardize its train fleet with the arrival of the multi-level coaches. However, 20 additional bilevels were purchased by the RTM in March 2018.

On December 18, 2007, the AMT awarded Bombardier a $386-million contract to build 160 multi-level commuter cars. These cars are based on NJ Transit's Multilevel series, and are able to enter the Mount Royal Tunnel, unlike the older GO-style BiLevel cars. They are numbered in the 3000s.

Canadian National (CN) and Canadian Pacific (CP) had long operated commuter trains in the Montreal area, but by the 1980s, their services had dwindled to one route each. The Société de transport de la communauté urbaine de Montréal (STCUM), or Montreal Urban Community Transportation Corporation (MUCTC), which already managed Metro and bus services across the Island of Montreal, assumed management of CN's Deux-Montagnes commuter service and CP's Rigaud service in 1982 as the two railways began scaling back their services.

In 1997, management and financing of both lines was transferred to the newly created Agence métropolitaine de transport (AMT), which had been established to distribute funding and coordinate transportation planning among the numerous transit operators throughout the Greater Montreal Region. Later that year, the AMT inaugurated service between Blainville and Jean-Talon (now Parc) train station in Montreal's Park Extension district, connecting to the Metro at Parc . Originally, the service was designed to provide a temporary alternative for motorists from Laval and the North Shore of Montreal, while the Highway 117 Dufresne Bridge was being repaired. The service proved to be so popular that the AMT continued to fund it, and even extended a number of trains to the Lucien-L'Allier station downtown in 1999, and continues to provide off-peak daytime weekday service on this line. The service was extended further north to Saint-Jérôme in 2007.

In 2000, the AMT inaugurated its service to McMasterville (which runs along a CN line), and later extended it to Mont-Saint-Hilaire in 2002.

In 2001, the AMT initiated a pilot project, launching service on a fifth line (using CP tracks) to Delson. This was later extended to Candiac in 2005. More information about the history of each line can be found in their respective articles.

In 2014, the AMT acquired the entire Deux-Montagnes line from CN, including the right of way, infrastructure, trackage, other railway equipment, grounds, curb lanes, rights in the Mount Royal tunnel and air rights, in a $97 million transaction.

On June 1, 2017, the AMT was disbanded to become the Réseau de transport métropolitain, then Exo, the new agency in charge of operating commuter rail and metropolitan bus services, while the Autorité régionale de transport became in charge of managing, integrating and planning public transportation in Greater Montreal.

On December 31, 2020, the Deux-Montagnes line was closed permanently, with the route from Montreal Central Station to Deux-Montagnes being converted into a section for the automated light metro service known as the Réseau express métropolitain.
