History

Several other public transport companies existed prior to the creation of the STM. From 1861 to 1886, the Montreal City Passenger Railway Company operated a small network of
horse-drawn trams (also called
streetcars in North America).
In 1886, the company changed its name to the
Montreal Street Railway Company. The first
electric tram appeared in 1892 and was nicknamed "the Rocket". The company underwent another name change in 1893: MSTR became the MTR for Montreal Island Beltline Railway. A year later, the network was fully electrified and in 1894, the last horse-drawn tram was taken out of service. From 1910 to 1911, the company was named Montreal Public Service Corporation before changing again to
Montreal Tramways Company.
Although they were put into service in 1919, buses only began to be widely used starting in 1925, with the creation of several regular lines. Then in 1937, the first
trolley buses were used. In 1939, the company had 929 trams, 224 buses and 7 trolley buses, serving about 200 million passengers per year. The replacement of tram lines by buses began in 1951, when a law was passed by the provincial government that transferred the overall management of transport in

to a public organization, the Commission de transport de Montréal (CTM). The last tram was withdrawn from service in 1959.
The
Montreal Metro was inaugurated in 1966; this year also saw the end of trolley bus service.
The CTM became the Commission de transport de la communauté urbaine de Montréal (CTCUM) in January 1970, and in 1985, rebranded itself again, becoming the Société de Transport de la Communauté Urbaine de Montréal (STCUM).
Commuter trains ceased to be the managed by the STCUM in 1996 and responsibility for this service was transferred to the newly created
Agence métropolitaine de transport.
It was not until January 1, 2002, at the time of the
merger of Montreal with other municipalities on the
Island of Montreal, that the Société de transport de Montreal was created, taking the place of the STCUM.
Streetcars

From 1861 to 1959, Montreal had an extensive

system. The streetcar network had its beginnings with the horsecar era of the Montreal City Passenger Railway in 1861. That private company would become the
Montreal Street Railway in 1886 and the
Montreal Tramways Company in 1911. The assets of the company were taken over by the city-owned Montreal Transportation Commission in 1951.
Regional transit service
The STM was formerly involved in the operation of regional transit services. The first such service was a set of bus routes inherited from the October 1980 expropriation of a private bus company called Metropolitan Provincial (1967) Inc. These regional bus routes operated from
downtown Montreal

to the
western part of the
Island of Montreal, as well as to off-island points located west, southwest, and northeast of the Island of Montreal. By the end of 1985, the STM (then known by the initials CTCUM) had exited the regional bus business to focus on its core territory (the Island of Montreal). Most of the regional bus routes were passed to private operators who provided services under contract to newly formed intermunicipal transit councils.
The second regional service involved the management of two
commuter train lines. On July 1, 1982, the CTCUM and the
Canadian National Railway (CN) entered into an agreement to integrate the
Montreal-Deux Montagnes commuter train line into the regular CTCUM bus and Metro network. The CTCUM paid CN to staff, run, and maintain the trains, while it set the fares and schedules. Passengers travelling within the CTCUM operating territory were able to transfer between the trains and the bus or Metro, with no fare supplement required to make a bus- or Metro-to-train transfer . On October 1, 1982, a similar agreement with the

(CP) went into effect, and CP's
Montreal-Rigaud commuter train line was integrated into the CTCUM network.
On January 1, 1996, responsibility for the commuter trains was transferred to the Agence métropolitaine de transport (AMT) (now

Services
Fares
Fares for bus and Metro services offered by the STM fall within the
fare structure of the Autorité régionale de transport métropolitain (ARTM). The STM operates in
Zone A, with the exception of Metro stations in Laval and Longueuil, which fall in Zone B. Passengers leaving the island of Montreal are expected to keep
proof of payment of a paid fare that covers zones A and B.
Beyond standard ARTM fares, the STM area has the following particularities:
* Bus line 747 YUL–Montreal–Trudeau Airport has a special price of that operates like a 24-hour all-modes Zone A. Other time-based all-modes fares (such as a monthly pass) are also accepted on this line.
* Residents of the
Agglomeration of Montreal (coterminal with Zone A) aged 65 or older are entitled to a "Free 65+ All Modes A fare".
the STM does not accept cash at Metro stations (cash is only accepted for bus fares); only debit and credit cards can be used to purchase tickets. Children between 6 and 17 years old, students 18 and over and seniors aged 65 and over have access to reduced fares.
Tickets and cash fares allow an unlimited number of uninterrupted transfers in a given direction for up to 120 minutes. Tickets and passes are validated at entry in the front of the bus or in the Metro. Certain articulated buses allow rear entry with validators at the back of the vehicle.
Opus

On April 21, 2008, the STM unveiled the
contactless smart card
A contactless smart card is a contactless credential whose dimensions are credit card size. Its embedded integrated circuits can store (and sometimes process) data and communicate with a terminal via NFC. Commonplace uses include transit ticket ...
called
Opus (a word that phonetically includes the French word ''puce'', which is the generic French word for the chip used in any type smart card) as a means of fare payment. In preparation for this new step in Montreal's public transportation network,
turnstiles which incorporate the reader and automated vending machines had already been installed in Metro stations; buses had previously been fitted with new fare boxes that incorporated the card reader in order to ensure the uniformity of methods of payment across Montreal's transit network and that of its suburbs.
Costs to the STM related to the project were approximately , compared to the original estimated cost of some $100 million. The project was originally supposed to be implemented in 2006. In 2019, the STM announced plans to introduce improved Opus card readers on buses beginning in 2020 in order to enable all-door boarding and debit card payment.
Schedules and route information
Each stop on each route is assigned a number and some of these systems require a user to know the number.
In 2017 the STM introduced "iBus", a real-time
GPS tracking system. It includes electronic signs inside buses showing the estimated time of arrival at upcoming stops and the busiest bus stops have electronic signs showing the estimated time of arrival of the next bus.

All 68 Metro stations are equipped with the MétroVision information screens which displays advertising, news headlines and weather information from
MétéoMédia, as well as STM-specific information regarding service changes, service delays and information pertaining to using the system.

Safety and security
Since the start of Metro service in 1966, the STM (and predecessors) has had its own transit enforcement unit.
Since 2021, the transit officers are sworn as Special Constables. They now be subject to the Police Act and, consequently, the authority of the ''Commissaire à la déontologie policière'' (police ethics commissioner).

, special constables are peace officers. Their mission is to maintain peace, order and public security, to prevent and repress crime and, according to the jurisdiction specified in their deeds of appointment, to enforce the law and municipal by-laws, and to apprehend offenders.
The
Service de police de la Ville de Montréal has a ''Unité métro'' (Metro Unit) that patrols Metro trains and stations as well. This unit has been in service since 2007.
Incidents
On May 10, 2012, smoke bombs were set off at
Lionel-Groulx,
Jean-Talon,
Préfontaine,
Fabre and
Pie-IX stations, resulting in evacuations of the affected stations and a complete shutdown of the Metro for over two hours. The incident was not officially linked to the
2012 Quebec student strike.
In 2009, a woman was arrested, handcuffed, and searched by
Laval Police Service () officers for allegedly not holding an escalator handrail. Her case was rejected by both Quebec Superior Court and the Quebec Court of Appeal. In November 2018, the
Supreme Court of Canada agreed to hear her appeal and in November 2019, ruled that her arrest and subsequent search were unlawful and had violated her rights. The court also awarded her $20,000 in damages.

; Montreal's system was the first in the world to be entirely rubber-tired (as not all of Paris's lines use tires). The Metro system is Canada's busiest subway system in total daily passenger usage; in 2017, serving an average of 1,235,200 daily passengers on an average weekday; a figure which surpassed that of the
Toronto subway and
Vancouver SkyTrain.
In 2016, 354 million riders (transfers not included) used the Metro.
Bus services

The STM bus service operates well over 200 bus routes serving a number of different markets. These routes serve an average of 1,403,700 daily passengers each weekday.
*Local network routes, numbered 10–299, generally operate seven days per week, from 5:00 am to 1:00 am. Some routes offer decreased services on weekends and holidays. Within this classification, some routes operate only at peak hours Monday through Friday, and sometimes only in peak directions. The ''Navettes Or'', numbered above 250, are specifically designed to serve the needs of senior citizens.
*All-night network routes, with route numbers from 300 to 399, generally operate from 1:00 am to 5:00 am, seven days per week, at a maximum
headway of 45 minutes. Some routes offer increased service early on Saturday and Sunday ("late" on Friday and Saturday).
*Express Network routes, numbered 400–499, are limited-stop routes. Some routes are classified as ''Metrobus'', and ''Trainbus'' and are geared to deliver commuters to specific Metro and commuter train stations, although these designations are no longer in use. Most Express routes operate only at peak hours Monday through Friday, and sometimes only in peak directions.
*Shuttle Network routes, numbered 700–799, are special-purpose routes serving
Canadiens hockey games, tourist areas like
Old Montreal and
La Ronde, as well as the 747 route running 24/7 between downtown and
Montréal–Pierre Elliott Trudeau International Airport.
On August 30, 2010, the STM introduced the "10 Minutes Max" network. This network, overlaid on both the local and express networks described above, schedules buses at a maximum
headway of 10 minutes, between 6 a.m. and 9 p.m., Monday to Friday, on 31 of the STM's busiest bus routes. A few routes support that maximum headway only in the customary peak direction mornings and afternoons, while some routes outside of the advertised network attain similarly short headways but within shorter periods. However, on January 6, 2023, the STM announced it planned to permanently end all "10 Minutes Max" routes due to budget cuts and constraints caused by the

From 2025, STM plans to only order electric buses,
after extensive testing confirmed that buses could handle Montréal's cold winters.
Pie-IX BRT
After an initial attempt in the 1990s, a bus rapid transit (BRT) line opened on
Pie-IX Boulevard in November 2022. It uses dedicated lanes, has priority at intersections and has all-door boarding to increase capacity and improve reliability on the corridor.
Taxibus
The STM also operates ten
taxibus lines where the creation of regular bus service is not feasible. Regular STM fares apply, except that no cash is accepted.

Paratransit service
The Société de Transport de Montréal operates a paratransit service for people with mobility problems. The lack of subway accessibility is critical for people whose mobility needs cannot be accommodated by stairs. STM's adapted transit is a system based on reservation, meaning that there is no room for flexibility. All trips must be booked at least one day in advance.
Service began in April 1980. More than 12,000 trips were made through this service daily.
On February 6, 2025, the Société de transport de Montréal has decided to transfer its paratransit service to external operators in 2026.
Current vehicles
The STM operates almost 2,000 buses in its fleet.
In recent years, only one model has been used – the

Facilities
STM buses are operated out of a number of garages located around the city. They are Anjou, Frontenac, LaSalle, Legendre, Mont-Royal, Stinson, St-Denis, and St-Laurent. St-Michel stores vehicles for Paratransit. The surface routes are divided into several divisions. Individual divisions have a superintendent, an on-duty mobile supervisor, a communications centre, and a garage facility tasked with managing the division's vehicle fleet and routes.
Metro trains are stored in the four garages at Angrignon, Beaugrand, Montmorency and Saint-Charles and there are three maintenance facilities at Duvernay, Plateau d'Youville and Viau.
Stops and shelters
There are 8,500 bus stops in the STM network. Each stop has a panel that indicates the number of routes that stops there, the type of service, if the bus goes to a Metro or train station and the bus stop code enabling one to obtain the schedule by telephone at 514-AUTO-BUS. The STM is in the process of changing all its bus stop panels to a new modern pole that displays the route numbers. The route number is color-coded for the type of service it offers, dark blue is for regular routes, green is for express, metrobus and R-bus routes, black for night routes and gold for senior shuttles. Advertising is provided by CBS. On November 8, 2010, the STM launched 3 prototypes of modern bus shelters to replace the old ones. They will run on a solar power system and lights in the shelter are to be controlled by motion sensor. Bus shelters at high-traffic intersections feature an interactive screen where people can use hand gestures to access weather, news and bus route information. Since the introduction of GPS in the fleet, the screen can also be used to track busses on the route.
