Urban transit began in
Montreal in 1861 when a line of
horse-drawn cars started to operate on Craig (now
St-Antoine) and
Notre-Dame streets. Eventually, as the city grew, a comprehensive network of
streetcar lines provided service in most of the city. But urban congestion started to take its toll on streetcar punctuality, so the idea of an underground system was soon considered.
Fifty years of projects In 1902, as European and American cities were inaugurating their first
subway systems, the
Canadian federal government created the Montreal Subway Company to promote the idea in Canada. Starting in 1910, many proposals were tabled but the Montreal Metro would prove to be an elusive goal. The
Montreal Street Railway Company, the Montreal Central Terminal Company and the Montreal Underground and Elevated Railway Company all undertook fruitless negotiations with the city. The
Montreal Tramways Company (MTC) was the first to receive the approval of the provincial government in 1913 and four years to start construction. The reluctance of elected city officials to advance funds foiled this first attempt. The issue of a subway remained present in the newspapers but
World War I and the following recession prevented any execution. The gradual return to financial health during the 1920s brought the MTC project back and attracted support from the
premier of Quebec. File:1910-MetroMontreal.png|1910 project under

World War II and the
war effort in
Montreal resurrected the idea of a metro. In 1944, the MTC proposed a two-line network, with one line running underneath
Saint Catherine Street and the other under
Saint Denis,
Notre-Dame and
Saint Jacques Streets. In 1951, the newly formed public Montreal Transportation Commission bought out the Montreal Tramways Company and started replacing streetcars with buses. The commission also proposed a single subway line reusing the 1944 plans and extending it all the way to
Boulevard Crémazie, right by the
D'Youville maintenance shops. By this point, construction was already well underway on
Canada's first subway line in
Toronto under
Yonge Street, which would open in 1954. Still, Montreal councillors remained cautious and no work was initiated. For some of them, including
Jean Drapeau during his first municipal term, public transit was a thing of the past. This would be the last missed opportunity, for the re-election of
Jean Drapeau as mayor and the arrival of his right-hand man,
Lucien Saulnier, would prove decisive. In the early
1960s, the
Western world experienced an economic boom and
Quebec underwent its
Quiet Revolution. From August 1, 1960, many municipal services reviewed the project and on November 3, 1961, the Montreal City Council voted appropriations amounting to $132 million ($1.06 billion in 2016) to construct and equip an initial network in length. The French influence is clearly seen in the station design and rolling stock of the Metro.
Rubber tires were chosen instead of steel ones, following the Parisian influence – as the rubber tired trains could use steeper grades and accelerate faster. 80% of the tunnels were built through rock, as opposed to the traditional
cut-and-cover method used for the construction of the
Yonge Subway in Toronto. under the supervision of the Director of Public Works, Lucien L'Allier. On June 11, 1963, the construction costs for tunnels being lower than expected, the Orange Line was extended by two stations at each end and the new termini became the and stations. The
Red Line (Line 3) was never built and the number was never used again. The railway, already used for a
commuter train to the
North Shore at
Deux-Montagnes, was completely renovated in the early
1990s and effectively replaced the planned third line. The next line would thus be numbered 5
(Blue Line). Subsequently, elements of the line, particularly the Deux-Montagnes commuter train, became the first line of the
Réseau Express Métropolitain.
Expo 67 The Montreal municipal administration asked municipalities of the
South Shore of the
Saint Lawrence River which would be interested in the Metro and
Longueuil received the rail link. The
Yellow Line (Line 4) would therefore pass under the river, from
Berri-de-Montigny station, junction of the Green Line and the Orange Line, to
Longueuil. imagined a network of of tunnels for the year 2000.
Extensions and unbuilt lines In 1970, the
Montreal Urban Community (MUC) was created. This group was made of municipalities that occupy the Island of Montreal and the city of Montreal was the biggest participant. MUC's mission was to provide standardized services at a regional level, one of them being transportation. The MUC Transportation Commission was thus created at the same time to serve as prime contractor for the Metro extensions. It merged all island transport companies and became the Société de transport de la communauté urbaine de Montréal (STCUM) in 1985 and then the
Société de transport de Montréal (STM) in 2002.
Montreal Olympics The success of the Metro increased the pressure to extend the network to other populated areas, including the suburbs on the
Island of Montreal. After being awarded, in May 1970, the
1976 Summer Olympics, a loan of $430 million ($2.7 billion in 2016) was approved by the MUC on February 12, 1971, to fund the extensions of the Green Line and the Orange Line and the construction of a transverse line: the
Blue Line (Line 5). The
Government of Quebec agreed to bear 60% of the costs. The work on the extensions started October 14, 1971, with the Green Line towards the east to reach the site where the
Olympic Stadium was to be built and
Autoroute 25 ( station) that could serve as a transfer point for visitors arriving from outside. The extensions were an opportunity to make improvements to the network, such as new trains, larger stations and even semi-automatic control. The first extension was completed in June 1976 just before the Olympics. The Green Line was later extended to the southwest to reach the suburbs of
Verdun and
LaSalle with the as the terminus station, named after the park and zoo. This segment opened at September 1978. (Line 1) In the process, further extensions were planned and in 1975 spending was expected to reach reached $1.6 billion ($7.3 billion in 2016). Faced with these soaring costs, the Government of Quebec declared a moratorium May 19, 1976, to the all-out expansion desired by Mayor
Jean Drapeau. Tenders were frozen, including those of the Orange Line after station and those of the Blue Line, whose works were not yet already underway. A struggle then ensued between the MUC and the Government of Quebec as any extension could not be done without the agreement of both parties. The Montreal Transportation Office might have tried to put the government in front of a
fait accompli by awarding large contracts to build the tunnel between station and the
Bois-Franc station just before the moratorium was in force.
Moratorium on expansion (Line 5) In 1977, the newly elected government partially lifted the moratorium on the extension of the
Orange line and the construction of the
Blue Line. In 1978, the STCUM proposed a map which includes a western extension of the Blue Line that includes stations in
Notre-Dame-de-Grâce, Montreal West, Ville St. Pierre, Lachine, LaSalle, and potentially beyond. The Orange Line) was gradually extended westward to station in 1980 and to station in 1981. As the stations were completed, the service was extended. In December 1979 Quebec presented its "integrated transport plan" in which the Orange Line was to be tunnelled to
Du Collège station and the Blue Line from station to
Anjou station. The plan proposed no other underground lines as the government preferred the option of converting existing railway lines to overground Metro ones. The mayors of the MUC, initially reluctant, accepted this plan when Quebec promised in February 1981 to finance future extensions fully. The moratorium was then modestly lifted on the Orange Line that reached
Du Collège station in 1984 and finally station in 1986. This line took the shape of an "U" linking the north of the island to the city centre and serving two very populous axes. The various moratoriums and technical difficulties encountered during the construction of the fourth line stretched the project over fourteen years. The Blue Line, which runs through the centre of the
island of Montreal, crossed the east branch of the Orange Line at the station in 1986 and its west branch at the
Snowdon station in 1988. Because it was not crowded, the STCUM at first operated the Blue Line weekdays only from 5:30 am to 7:30 pm and was circulating only three-car trains instead of the nine car trains in use along the other lines. Students from the
University of Montreal, the main source of customers, obtained extension of the closing time to 11:10 pm and then 0:15 am in 2002.
Recession and unfinished projects In the late 1980s, the original network length had nearly quadrupled in twenty years and exceeded that of Toronto, but the plans did not stop there. In its 1983–1984 scenario, the MUC planned a new underground line, the
White Line (Line 7) ( station to
Montréal-Nord) and several surface lines numbered
Line 6 (
Du College station to
Repentigny), Line 8 ( station to
Pointe-aux-Trembles), Line 10 (
Vendome station to
Lachine) and Line 11 ( terminus to
LaSalle). In 1985, a new government in Quebec rejected the project, replacing the Metro lines by commuter train lines in its own 1988 transport plan. Yet the provincial elections of 1989 approaching, the White Line project reappeared and the extensions of the Blue Line to
Anjou (
Pie-IX,
Viau,
Lacordaire,
Langelier and ''Galeries d'Anjou
) and the Orange Line northward (Deguire
/Poirier
, Bois-Franc
and Salaberry'') were announced. At the beginning of the 1990s, there was a significant deficit in public finances across Canada, especially in Quebec, and an economic recession. Metro ridership decreased and the Government of Quebec removed subsidies for the operation of urban public transport. Faced with this situation, the extensions projects were put on hold and the MUC prioritized the renovation of its infrastructures.
Creation of AMT, RTM, ARTM, and improvements In 1996, the Government of Quebec created a supra-municipal agency, the
Agence métropolitaine de transport (AMT), whose mandate is to coordinate the development of transport throughout the
Greater Montreal area. The AMT was responsible, among others, for the development of the Metro and suburban trains. On June 1, 2017, the AMT was disbanded and replaced by two distinct agencies by the Loi 76 (English: Law 76), the
Autorité régionale de transport métropolitain (ARTM), mandated to manage and integrate road transport and public transportation in Greater Montreal; and the
Réseau de transport métropolitain (RTM, publicly known as exo), which took over all operations from the former Agence métropolitaine de transport. RTM now operates Montreal's commuter rail and metropolitan bus services, and is the second busiest such system in Canada after
Toronto's
GO Transit.
Laval extension Announced in 1998 by the STCUM, the project to extend the Orange Line past the Henri-Bourassa terminus to the
city of Laval, passing under the
Rivière des Prairies, was launched March 18, 2002.
Major renovations Since 2004, most of the
STM's investments have been directed to rolling stock and infrastructure renovation programs. New trains (
MPM-10) have been delivered, replacing the older
MR-63 trains. Tunnels are being repaired and several stations, including , have been several years in rehabilitation. In 2016, many electrical and ventilation structures on the surface were completely rebuilt to modern standards. In 2020, work to install
cellular coverage in the Metro was completed. Station accessibility has also been improved, with over 30 of the 68 stations having elevators installed since 2007.
Réseau express métropolitain In August 2023, the first phase of the
Réseau express métropolitain (REM) opened between
Gare Centrale (
Bonaventure) and
Brossard. The system is independent of, but connects to and hence complements the Metro. Built by
CDPQ Infra, part of the Quebec pension fund
Caisse de dépôt et placement du Québec. In November 2025, the second phase of the REM opened between Deux-Montagnes and Gare Centrale. The opening of the new branch introduced 2 new interchanges at Metro stations
McGill and
Édouard-Montpetit with an
Exo interchange at the
Côte-de-Liesse station that opened two months after the original opening date in January 2026. The Anse-à-l'Orme Branch (A3) has a scheduled opening date of may 18th 2026 and the YUL-Aéroport-Montréal-Trudeau branch (A2), still having it's opening date planned for 2027.
Future growth Blue Line extension to Anjou Following the opening of the Blue Line in the 1980s, various governments have proposed extending the line east to
Anjou. In 2013, a proposal to extend the line to Anjou was announced by the STM and the Quebec government. On April 9, 2018, premier of Quebec
Philippe Couillard and Prime Minister
Justin Trudeau announced their commitment to fund and complete the extension, then planned to open in 2026. In March 2022, it was announced that the federal government had agreed to provide $1.3 billion to the extension, with further costs to be covered by the provincial government. The extension will include five new stations, two bus terminals, a pedestrian tunnel connecting to the
Pie-IX BRT and a new park-and-ride. Overall, the project is estimated to cost around $5.8 to $6.4 billion and is scheduled to be completed in 2030. Initial construction work began in August 2022.
Pink Line In 2017,
Valérie Plante proposed the
Pink Line as part of her campaign for the office of Mayor of Montreal. The new route would have 29 stations and would connect downtown with the northeastern parts of Montreal, as well as the western end of Notre-Dame-de-Grâce and Lachine. The project has since been added to Quebec's 10-year infrastructure plan, and feasibility studies for the line's western section began in June 2021. == Network ==
