A 67 km driverless metro owned by Quebec's pension fund, paid per passenger-kilometre by the transit authority. The province will supply more than half the revenue it collects, the Auditor General found.

Montreal's REM is a 67 km driverless light metro owned by CDPQ Infra, the Quebec pension fund's infrastructure arm, rather than by the city or the transit authority; the regional authority ARTM pays it a fee for every passenger-kilometre travelled. Trains carry no driver and are run from a control centre, with roving agents in stations and on the network. The first branch opened in July 2023, but Deux-Montagnes commuters rode replacement buses for almost five years until November 2025. Ice in switches and snow in train gear have caused repeated winter shutdowns.

Live 📅 since 2023

📊 Impact

Quebec's Auditor General reported in November 2024 that the provincial government's contribution will supply more than half of the ridership revenue the REM collects over its operating life, and that on CDPQ Infra's own projections Quebec would only begin earning a return on its equity in about 25 years.

🎓 Lesson

Handing a metro to a pension fund got it built and running while comparable public projects were still in planning. The bill arrives later and elsewhere: a per-passenger-kilometre payment the transit authority owes for decades, indexed upward before the first train ran, and an automated railway that still has to survive a Montreal winter.

↗ ARTM — Réseau express métropolitain (REM) archived copyThe paying authority describes the ownership plainly: 'The Réseau express métropolitain (REM) project is led by CDPQ Infra, a subsidiary of the Caisse de dépôt et placement du Québec.' ARTM's own role is limited to 'planning the integration of REM services to the metropolitan collective transport network regarding passenger information, pricing, service schedule harmonization and transfer point arrangements'.
↗ Vérificateur général du Québec — November 2024 report, chapter 5 (REM)Published 20 November 2024Carries the impact claim verbatim: 'Depuis notre audit de 2018, les coûts de construction du Réseau express métropolitain (REM) établis par la Caisse de dépôt et placement du Québec (CDPQ Infra) ont augmenté alors que l'investissement en capital-actions du gouvernement n'a pas changé. La contribution du gouvernement du Québec représentera plus de la moitié des revenus d'achalandage que percevra le REM au cours de son exploitation. Selon les prévisions de CDPQ Infra, le gouvernement du Québec commencerait dans environ 25 ans à obtenir un rendement sur son investissement en capital-actions.' (Construction costs rose while the government's equity stake did not; Quebec's contribution will make up more than half the ridership revenue the REM collects; a return on that equity is roughly 25 years away.)
