TheRéseau express métropolitain (French:[ʁezoekspʁɛsmetʁɔpɔlitɛ̃],REM,lit. 'Metropolitan Express Network') is alight metro rapid transit system inGreater Montreal, Quebec, Canada. As of November 2025,[update] it consists of nineteen stations spanning 50 kilometres (31 mi), connectingDowntown Montreal with the suburb ofBrossard and the northwesternMontreal suburbs. TheWest Island branch will open in the second quarter of 2026 and the branch to theMontréal–Trudeau International Airport will open in 2027. A portion of the route was taken over from theExo commuter railDeux-Montagnes line and has been converted to light metro standards.
The 67-kilometre (42 mi) driverless metro system is projected to costCA$8.34 billion. It is independent of, but connects to and complements, the existingMontreal Metro operated by theSTM, and is fully fare-integrated withARTM's system. Trains on the network arefully automated anddriverless, and the stations are completely enclosed and climate controlled, featuringplatform screen doors.
The line was built byCDPQ Infra, a subsidiary of theCaisse de dépôt et placement du Québec, an institutional investor that manages various public and para-public pension plans and insurance programs in Quebec. The first section of the REM between theBrossard on theSouth Shore andCentral Station in Downtown Montreal opened on 31 July 2023. The system was formally inaugurated on 14 November 2025 in a ceremony attended by Prime MinisterMark Carney, Premier of QuebecFrançois Legault and Mayor of MontrealSoraya Martinez Ferrada. The second section of the REM opened on 17 November 2025, extending the line to the north through theMont Royal Tunnel and to the northwest toDeux-Montagnes.
The Réseau express métropolitain has its origin in various railway projects, realized or not, which have succeeded each other in Montreal since the beginning of the20th century.
In 1918, theCanadian Northern Railway (CNoR) completed construction of atunnel under Mount Royal to allow its trains arriving from the north to reach downtown Montreal. Since ventilation in the tunnel was insufficient to use steam locomotives, the line through the tunnel was electrified from its opening.[7] In the 1990s, theAgence Métropolitaine de Transport (AMT) took over operation of theDeux-Montagnes line fromCanadian National, renovating it between 1993 and 1995 – with trains running through the tunnel to reach downtown Montreal.[8]
When theMontreal Metro was developed in the 1960s, initial plans involved theRed Line that would use theCanadian National Railway (CN) tracks passing under Mount Royal to reach the northwest suburb ofCartierville from downtown Montreal.[7][9] When Montreal was chosen to hostExpo 67 in 1962, the Red Line was dropped – with theYellow Line (Line 4) linkingMontreal to theSouth Shore suburbs being built instead.[9][10] The Red Line was still planned for construction as a "regional metro" line in the early 1980s.[11]
Vaudreuil–Hudson – acommuter rail line serving the west of Montreal – shares its tracks with freight trains, thereby limiting the quantity and frequency of trains that can be run.[12] From the 2000s onwards, municipalities in the west of the island pushed for improved commuter train service. The AMT proposed upgrades and improvements to the Vaudreuil–Hudson line, with theAéroports de Montréal proposing anautomated light metro (similar to theCanada Line inVancouver) to serve the airport and the surrounding area.[12]
From the 1970s onwards, proposals for improved public transport to connect the South Shore with downtown Montreal were made, often proposing the use of theChamplain Bridge, which opened in 1962.[12] In the 1990s and 2000s, proposals were made for alight rail line that would use the Champlain Bridge ice control structure to cross theSt. Lawrence River.[13][14] In 2011, the Canadian government announced that anew bridge would be built to replace the existing Champlain Bridge, with two lanes reserved for public transit.[15] In 2013, the Quebec government announced that it was proposing a new light rail line to cross the bridge.[16] The new Champlain Bridge opened in 2019, with a separate deck reserved for the future rail corridor.[17]
On 13 January 2015,Premier of QuebecPhilippe Couillard andMichael Sabia, CEO of theCaisse de dépôt et placement du Québec (CDPQ), announced that theCrown corporation would define, build and finance major transportation projects in the province, withCA$7.4 billion planned to be spent on infrastructure from 2014 to 2024.[12] Two of these projects were theSouth Shore Line and the Train de l'Ouest toward theWest Island, which eventually merged to become the core of theRéseau express métropolitain project.[18]
On 22 April 2016, Sabia and Montreal mayorDenis Coderre unveiled the project, then known as theRéseau électrique métropolitain (REM) to the media.[19] The estimated completion date for the first portion of the system was December 2020.[19] On 22 June 2016, CDPQ Infra published two requests for qualification: one for the engineering, procurement, and construction contract and the other for the rolling stock, systems, operation, and maintenance. The estimated values of the two contracts were $4 billion and $1.5 billion, respectively.[20]
On 25 November 2016, CDPQ Infra announced the addition of three new stations to the project. These new stations—Central Station,McGill, andÉdouard-Montpetit—would improve downtown Montreal service by integrating the REM with theMontreal Metro through connections to theOrange,Green andBlue Lines. Included with news of the three new stations was an increased price tag of $5.9 billion for the entire project.[21][22]
On 15 June 2017, the Government of Canada pledged $1.28 billion to finance the project, completing the financing of the project.[23] In February 2018, CDPQ Infra announced that the project had been renamedRéseau express métropolitain (REM), would cost $6.3 billion to build, and that the network would open gradually between 2021 and 2023 – starting with the South Shore.[24]
On 28 June 2016, CDPQ Infra launched two public tenders in parallel: one for "Engineering, Procurement and Construction" (EPC, or "Ingénierie, Approvisionnement et Construction des infrastructures" (IAC) in French), and a second, for "Rolling Stock, Systems and Operation and Maintenance Services" (RSSOM, or "Fourniture du Matériel Roulant, de Systèmes de conduite automatique et de Services d'Exploitation et de Maintenance" (MRSEM) in French).[25][26] The estimated values of the two contracts were $4 billion and $1.5 billion, respectively.[20] Following a prequalification phase, the Caisse's subsidiary announced, on 10 November 2016, the qualified candidates that would be allowed to submit a bid:
Ansaldo STS-Hitachi and China Railway International were not allowed to bid.[27]
According toLa Presse, final bids were submitted to CDPQ Infra on 27 October 2017.[29] On 10 November 2017, the date of the planned announcement of the selected contractors, the procurement process was "postponed indefinitely" to provide more time for analysis and evaluation of the bids received.[30] On 8 February 2018, CDPQ Infra finally announced its selection: the Groupe NouvLR consortium for the EPC contract (SNC-Lavalin Grands Projets, Dragados, Aecon, Pomerleau, EBC, and AECOM) and the Groupe des Partenaires pour la Mobilité des Montréalais for the RSSOM contract (Alstom and SNC-Lavalin O&M).[28][31] As part of RSSOM contract, Alstom would deliver 212Alstom Metropolis cars, forming 106 two-car trains.[32] The contracts' total value was estimated to be around $6.3 billion, of which approximately 80% was for the EPC contract.[33] Groupe PMM rebranded as "Pulsar" in October 2025.[34]
Preparatory work began in late March 2018.[35] On 12 April 2018, the project officially broke ground.[36] In December 2019, CDPQ revised the capital cost of the project to $6.5 billion, an increase of $230 million.[37][38] In February 2020, CDPQ confirmed the names of the 26 stations on the network.[39]
In October 2020, thetunnel boring machine "Alice" (named after Canadian geologistAlice Wilson) started the tunnelling process toMontréal–Trudeau International Airport.[40] In October 2020, the first completed train arrived in Montreal from India, where it had been manufactured.[41]
In November 2020, a disruption from an "unexpected" explosion during the renovation of theMount Royal Tunnel, likely caused by leftover century-old explosives, delayed the opening of the central section of the REM from 2022 to 2023.[42]
In June 2021, CDPQ updated the project cost to $6.9 billion, an increase of $350 million, citing impacts from theCOVID-19 pandemic in Montreal.[43][44] In June 2022, CDPQ Infra acknowledged that construction issues with the Mount Royal Tunnel,[45] labour shortages, and material supply issues would postpone the opening of most REM stations to 2024. The delay had also resulted in higher costs for the project overall, exceeding the previously projected budget of $6.9 billion.[46] No new estimate of the project cost was provided.
In November 2024, CDPQ announced that major construction work on the central section of the line had been completed, with testing to follow in 2025.[47][48] An updated opening date of the fourth quarter of 2025 was announced. CDPQ also stated that the project cost had increased toCA$8.34 billion – noting that they shouldered responsibility for cost overruns.[47][48] Construction on the branch to Montréal–Trudeau International Airport continued, with an estimated opening date of the first quarter of 2027.[49]

The first five stations on the network, between Central Station and Brossard, opened for full service on 31 July 2023.[50][51] An opening ceremony was held on 28 July 2023, with Prime MinisterJustin Trudeau, Premier of QuebecFrançois Legault, Mayor of MontrealValérie Plante, president and CEO of CDPQ Charlies Emond, and president and CEO of CDPQ Infra Jean-Marc Arbaud inaugurating the line.[52]
On the weekend of 29 and 30 July 2023, free service was available to the public.[53][54] On the first day of public access, over 20,000 people rode the REM in the morning, prompting staff to turn away new riders.[55]
Within the first three days of revenue operation, the new line suffered a number of service disruptions caused by stuck railway switches and computer issues. A spokesperson remarked that "there's always some adjustments to be made" with a new system on the scale of the REM.[56][57][58][59]
As of 11 September 2023,[update] the system had carried more than 1 million passengers, with daily ridership of more than 30,000 for the month following its opening.[60] In April 2024, CDPQ announced that weekday ridership had increased again, with "up to 36,000 daily riders".[3] In September 2024, average weekday ridership had risen to 37,000 daily passengers, with Tuesdays being the busiest day (42,000 passengers).[61] During an interview with Radio-Canada in February 2025, president and chief executive officer of CDPQ Infra Jean-Marc Arbaud stated ridership had increased to 45,000 on its busiest day.[62]
Dynamic testing on the north and west branches of the line began in mid-2024.[63] Weekend service was stopped from February to mid-September 2025 to allow final installations and testing to take place. From 5 July 2025 to 17 August 2025, the REM shut down completely to enable testing of the central section of the line, which was scheduled to open in November 2025.[48][64] Several shuttle bus lines were made available to customers during the service interruption.
On 25 September 2025, it was announced that the branch toAnse-à-l'Orme would be delayed to open sometime in the second quarter of 2026.[65]
The REM system was formally inaugurated on 14 November 2025 in a ceremony attended by Prime MinisterMark Carney, Premier of Quebec François Legault, Montreal MayorSoraya Martinez Ferrada and CEO of Caisse de dépôt et placement du Québec Charles Emond.[66] The entire REM line, including the new stations, was free to ride on the weekend of 15 and 16 November.[67] The 14-station extension toDeux-Montagnes officially opened for revenue service on 17 November.[68]
Four stations will open in the second quarter of 2026 on the Anse-à-l'Orme branch in the next stage.[49] The branch toMontréal–Trudeau International Airport is planned to open in 2027 with two stations.[69] In August 2024,La Presse reported that CDPQ Infra refused to confirm thatGriffintown–Bernard-Landry station would be completed by 2027, but that construction could take place while the REM is in operation.[70]


The primary route follows theMount Royal Tunnel, where new underground stations have been built to connect with the existing McGill and Édouard-Montpetit Metro stations. A new connection to theMascouche commuter rail line was built near theA-40 at the Côte-de-Liesse station to allow this line, which previously used the tunnel, to have access to downtown.
Southeast fromCentral Station, the line follows existing rail lines until Marc-Cantin Street, where it transitions to an elevated guideway and crosses toNuns' Island, and then uses arail deck constructed on thenew Champlain Bridge to cross theSt. Lawrence River. Three stations inBrossard on the South Shore have been built: Panama, connecting to the existing bus terminal;Du Quartier, directly connected to theDIX30 commercial district; andBrossard, the site of a bus terminal built along with the station, along with the line's maintenance depot.
The northwest branch is a conversion of theDeux-Montagnes line, with a second track added beyondBois-Franc station and all at-grade crossings eliminated. On the West Island, a new airport branch will separate from the main line near theA-13, with a stop atTechnoparc Montreal, before terminating atMontréal–Trudeau International Airport. The main West Island branch follows an existing freight rail spur throughPointe-Claire, then crosses and follows theA-40 just east of St-Jean Boulevard and continues throughKirkland before ending inSainte-Anne-de-Bellevue. These lines are mostly elevated to avoid at-grade crossings.
In the city centre, Central Station connects with theOrange Line atBonaventure, McGill with theGreen Line[22] and Édouard-Montpetit with theBlue Line.[22]


When fully completed, the REM will consist of 26 stations on three branches. Twelve of these stations are on the former suburbanDeux-Montagnes line and became part of the REM after being converted torapid transit standards. Several have received new names since the project's inception.[71] All stations on the REM will be accessible, and STM Metro interchange stations at McGill and Édouard-Montpetit have been retrofitted for accessibility.[72]
All stations on the main line of the Réseau express métropolitain have atrain frequency of 2.5 minutes during rush hour and 5 minutes at other times, both toward Brossard station and toward the three different branches.[73]

TheAlstom Metropolis Saint-Laurent[82] is a type oflight metro train built byAlstom for the Réseau express métropolitain, using theAlstom Metropolis platform. Trains run as a single two-car train at quieter times and as paired four-car trainsets during rush hour.[83] The trains arefully automated (GoA4), with no driver or attendant on board.[83]
In April 2018, a $2.8-billion contract was awarded to Alstom andSNC-Lavalin to deliver a driverless light metro, including rolling stock and automatic signalling, and to operate and maintain the line.[84] This contract included 212 Alstom Metropolis cars, forming 106 two-car trains.[84] Built at Alstom'sSri City plant in India, the trains were delivered to Montreal by ship.[85]

Each two-car train seats 64 passengers, with standing capacity for around 300. A four-car trainset can carry a maximum of 780 people at rush hour.[83][86] The livery is white, grey, and bright green, matching the REM logo.[83] The trains have large front windows, allowing passengers to take in views from the front of the train.[87] A dedicated space for wheelchair users is available, and the trains feature Wi-Fi, air conditioning, and heated floors.[87] CDPQ Infra indicated it is "confident that the trains ... will be able to withstand ... winter conditions", with the trains featuring double glazing, ice-scrapingpantographs, and heatedautomatic couplings.[88] The front lights of the trains are inspired by theChamplain Bridge.[83]
Compared to theAzur trains used on theMontreal Metro, the REM trains use steel wheels rather thanrubber tires, are 17% wider, are faster (with a top speed of 100 kilometres per hour (62 mph) on the Champlain Bridge), and are fully automated.[86][87] However, the REM trains are shorter and can carry fewer passengers per trainset, although the REM has the ability to increase capacity to meet demand.[86][87] The REM metro trains are also exposed to the weather, unlike the fully underground existing metro system.
Stations on the REM were designed by a joint venture of architects – Lemay,Perkins&Will and Bisson Fortin. Station designs generally feature glass, horizontal and vertical lines, and wood.[89][90][91]
Across the REM, 12 pieces of permanent artwork will be installed at a cost of $7.3 million, as part of Quebec'spercent for art programme.[92][93] An additional $500,000 will fund temporary artworks, created by students of four Montreal universities (Concordia,McGill,Université de Montréal andUniversité du Québec à Montréal).[92] The first works were unveiled in October 2024 atBrossard andPanama stations.[93] Further artworks for theAnse-à-l'Orme,Central Station,Sainte-Dorothée,Bois-Franc andDeux-Montagnes stations were announced in February 2025.[94]
In a report prepared by theBureau d'audiences publiques sur l'environnement [fr] (BAPE), released on 20 January 2017, CDPQ Infra was criticized for failing to provide crucial information on the project's financial model, environmental impact, and impact on ridership levels on existing public transit systems across Greater Montreal. Without such information, the BAPE declared that it was "premature to authorize the approval of this project".[95] The BAPE also stated that CDPQ Infra had not met its obligations with regard to transparency, as it had failed to provide information in a timely fashion on the ridership levels of the REM's three branches.[95] CDPQ Infra was also reproached for not studying the impact of the REM on existing public transit authorities.[95] CDPQ Infra was criticized for not being able to answer questions like how much tickets would cost, whether municipalities served by the REM would have to pay for the necessary infrastructure for access to it, and whether municipalities would have to contribute to the REM's operation.[95]
A lawsuit filed by Coalition Climat further alleged that the REM project violatedfederalism for a lack of federal assessment of the potential harm to citizens' environmental rights by its potential contribution tonoise pollution andurban heat islands. The lawsuit was dismissed by theQuebec Superior Court on 13 December 2017.[96]
Another controversy occurred in November 2019, when Montreal mayor Valerie Plante proposed naming Griffintown's REM station after former Quebec premierBernard Landry, who was part of the Parti Québécois. This sparked a backlash from the city's Irish community.[97] As a compromise, the station was namedGriffintown–Bernard-Landry, which still proved controversial.[98] Local politicians and transit advocates also noted their annoyance that the station was not opened with the other REM stations in August 2023,[99] and that a construction staging yard was preventing the construction of a park in the neighbourhood.[70]
As agreed in 2018, the financial model underpinning the project requires theAutorité régionale de transport métropolitain (ARTM) to pay CDPQ Infra $0.72 for each kilometre traveled by a passenger following the project's opening. This amount will increase with inflation.[100][101] CDPQ expects arate of return of around 8 or 9 percent over the 99-year period.[101]
Although fare revenues will not fund other transit projects or agencies (such as theSociété de transport de Montréal), CDPQ argued that the REM will provide long-term income for pensions, stating, "when a user takes the REM, they are helping to finance their future retirement".[102] CDPQ also argued that the project risk lies with itself and not the provincial government or municipalities.[101]
The project's construction cost is financed through funding from CDPQ (initially $3.2 billion), theGovernment of Quebec ($1.283 billion), theGovernment of Canada ($1.283 billion), andHydro-Québec ($295 million).[103] CDPQ shouldered responsibility for cost overruns that ultimately amounted to $8.34 billion.[47]
On 20 May 2019, the Quebec government announced that it had requested CDPQ Infra to study two REM extensions. One route would extend nearly 20 kilometres (12 mi) north toCarrefour Laval and the other nearly 30 kilometres (19 mi) south toChambly andSt-Jean-sur-Richelieu.[104] The government also made a request to determine the best electrified transit system to be put in place for the East Island, with the possibility of it being a new REM project.[104] The proposal became the REM de l'Est project.
The federal government had requested that the Canada Infrastructure Bank study a possible extension of the REM toDorval Exo railway station andDorval Via Rail station to connect with Exo andVia Rail trains.[105] This station would have been about a 1-kilometre (0.62 mi) extension from theAirport station. TheSTMbus station is located south of theCP andCNtracks and west of the Via Rail station.
The city of Montreal requested two stations instead of one at Bassin Peel.[106] The second station would be added betweenÎle-des-Soeurs andGriffintown–Bernard-Landry stations.[107][108] In August 2024, CDPQ Infra noted that the station was technically feasible.[70]
The REM de l'Est was a proposed second REM line that would have been 32 km (20 mi) long and included 23 stations. Announced in 2020,[109][110] it would have used the same technology as the REM but would not be connected directly to the first section of the network.
Beginning a few blocks east of Robert-Bourassa Boulevard (and therefore from Central Station), the line would have run east on an elevated guideway along René-Lévesque Boulevard and Notre-Dame Street until St-Clément Street, where it would have turned north and split into two branches:
In May 2022, the project was abandoned,[111] and as of mid-2023, nothing has been announced about its eventual replacement, which is under study, except that it is to be named Projet structurant de l’Est (PSE) instead of REM.[112]
In partnership with theCity of Longueuil and theMunicipality of Brossard, the Quebec government announced a proposed extension of the REM through the South Shore of Montreal. This branch was originally referred to as REM 2.0, but was also commonly called the Taschereau REM, and was planned to connect the existing REM line atTerminus Panama to the Montreal metro atTerminus Longueuil.[113] REM 2.0 would followTaschereau Boulevard for much of its length, superseding earlier proposals for an electric tramway, the East–West Electric Line (Lien électrique est–ouest, or LÉEO),[114] to connect these transit hubs. The government of Quebec suggested that this REM line could ultimately continue in either direction to the municipalities ofChâteauguay andBoucherville respectively.[115]

Longueuil mayorCatherine Fournier was present at the REM's inauguration and first rides. During the ride, Fournier made clarifying remarks about REM 2.0, confirming the future of the project. Fournier added that the segments of REM 2.0 along Taschereau Boulevard would be elevated, while the portions along theQuebec Route 132 would be at ground level to serviceOld Longueuil and beyond.[116][117]
Following the REM's inauguration, Fournier held an interview withLa Presse where she indicated that she had taken part in continued conversation with Quebec's Minister of Transport,Geneviève Guilbault, who reiterated the province's interest in the project and stated that the extension was under study.CDPQ Infra responded to the interview, confirming that the project was still planned, with ongoing discussions involving the provincial authorities.[117]
Following this interview, in late 2023, Mayor of Brossard Doreen Assaad announced a plan to construct a new, pedestrianized downtown forBrossard, centred onPanama station, to be completed by 2040.[118][119] The announcement indicated that Brossard would aim to implement a double-track, street-level electrictram along Taschereau Boulevard. In follow-up interviews, Brossard's city administration opposed the construction of an elevated REM extension along the Taschereau corridor, indicating that it was not compatible with its vision for Brossard's new downtown.[120]
Assaad then elaborated on this statement in a press release about road safety on Taschereau Boulevard, stating that the citizens and mayor's office did not see a return on investment for an elevated REM along Taschereau but would defer to theGovernment of Quebec as Taschereau Boulevard is aQuebec Route and under provincial jurisdiction.[121] Assaad indicated that the city was designing its future downtown with alighter mode of public transit to test the feasibility of the REM model and sought to keep the municipality's voice in the conversation.
In an early 2024 press release, CDPQ Infra said that it would be releasing the results of its analysis of the Taschereau REM branch, as well as holding meetings with municipal officials and other relevant parties to inform them of the direction of its upcoming public transit projects.[122] In response to this announcement, Fournier commented that she was supportive of the Taschereau REM project but that Longueuil had not received an update from CDPQ Infra for over a year and a half.
On 29 January 2024, CDPQ Infra announced that it was withdrawing from the proposed extension, leaving local mayors to coordinate any future development of Taschereau Boulevard with the soon-to-be-created provincial government agency, Mobilité Infra, for large public transit projects.[123]
On 21 July 2025, Fournier and Assaad announced that the transit corridor on Taschereau Boulevard would be abus rapid transit (BRT) system rather than a rail system[124] and Renée Amilcar, CEO of Mobilité Infra, confirmed that the BRT system was included in the first four projects that the newly minted government agency would tackle.[125]
In the end, line 3 would be eliminated in favour of an entirely new line (4 - yellow) running under the St. Lawrence River to service the site of the 1967 World Fair.
The partnership between the governments of Quebec and Canada seeks to develop a proposal for an LRT system along the Highway 10 corridor to downtown Montréal. This collaboration focuses on the need to find a long-term solution for public transportation along the corridor by employing the existing Champlain Bridge Ice Control Structure (Estacade).
You could take the new REM for free July 29 and 30 [at the Open House] – during the light rail network's inaugural weekend. Trips between central station in downtown Montreal and Brossard will be free 9 a.m. to 7 p.m., tweeted the Quebec government. The REM is set to be inaugurated on July 28, before officially opening for its regular runs July 31.
Construction on the Mount Royal tunnel set to begin on Monday following delays will be ongoing until 2022, causing detours for off-island commuters who rely on it daily. ... Transit users who relied on the tunnel to enter the city from Mascouche can take note that three trains departing in the morning and afternoon will take a different route to reach the central station downtown. Other trains will stop at the Ahuntsic station – from there, users can take a number of express buses to the metro network. They can also transfer at the Sauvé train station to get to the metro, but it may be busy, according to the Societe de transport de Montreal (STM).

"We're very confident that the trains we ordered will be able to withstand our winter conditions," said Mack Tall, the president and chief executive officer for CDPQ Infra, which is managing the project.
