The Société de transport de Montréal (STM) operates Metro and bus services in Montreal, and transfers between the two are free inside a 120-minute time frame after the first validation.

Fares are only partially integrated with the Réseau de transport métropolitain (RTM) commuter rail system, which links the Metro to the outer suburbs via six interchange stations (Bonaventure, Lucien-L'Allier, Vendôme, De la Concorde, Sauvé, and Parc).
The RTM sells tickets allowing the use of both its trains and the Metro (TRAM titles) while the STM tickets do not permit the boarding of trains.

Fare payment is via a barrier system accepting magnetic tickets and RFID like contactless cards.
A rechargeable contactless smart card called "OPUS" unveiled on April 21, 2008 provides seamless integration with other transit networks of neighboring cities by being capable of holding multiple transport tickets: tickets, books or subscriptions, a subscription for Montreal only and commuter train tickets.
Moreover, unlike the magnetic stripe cards, which had been sold alongside the new OPUS cards up until May 2009, the contactless cards are not at risk of becoming demagnetized and rendered useless and do not require patrons to slide them through a reader.

Since 2015, customers have been able to purchase an OPUS card reader to recharge their personal card online from a computer.
In 2016, the STM is developing a smart phone application featuring NFC technology, which could replace the OPUS card.
