The OPUS contactless card launched across Quebec transit in 2008 and is accepted by every operator in Greater Montreal — the STM, exo, the RTL, the STL and the REM. Since the 2017 reorganisation the ticketing platform belongs to the ARTM, the regional authority that also rewrote the fares: a reform rolled out from July 2021 to 2023 replaced 17 separate fare grids and more than 750 fare products with four zones. Riders still cannot tap an ordinary bank card, except on ten exo bus lines north of the city where a pilot has run since December 2024. A CAD 146M replacement programme, Concerto, contracted to Masabi, is meant to bring contactless bank cards network-wide from 2026 and post-payment in 2027; since July 2026 some Android users can validate a virtual OPUS at metro turnstiles.
Fare reform replaced 17 fare grids and more than 750 distinct fare products with 4 zones across the metropolitan region (ARTM). Single fare held at CAD 3.50 through the July 2022 phase; fares indexed about 3% on 1 July 2026.
🎓 Lesson
A regional fare authority can unify a fragmented fare structure years before it can modernise the technology underneath it. Montreal cut its zones from eight to four between 2021 and 2023, yet in 2026 a bank card still only works on a handful of suburban bus routes.

↗ Wikipedia — Opus cardWeakest source, used only for two supporting details: the card follows the Calypso / ISO-IEC 14443 standard, and 'Following Montreal's public transport reorganization effective June 1, 2017, the Opus ticketing system has been the property of the Autorité régionale de transport métropolitain (ARTM), which has delegated its management to the STM.' The delegation detail is single-sourced and deliberately kept out of the entry fields.
