STM’s Blue line to open late Saturday for Hydro-Québec work
Posted November 10, 2026 9:47 am.
STM’s Blue line will begin service later than usual Saturday morning due to electrical maintenance work.
The first metro will begin at 9:30 a.m. rather than 5:30 a.m.
A shuttle service will operate along the Blue line’s route and stop at all stations starting at 5:30 a.m. until the metro service is restored.
Riders can alternatively take one of the bus lines along the route: 93 between Saint-Michel and Parc stations, and line 51 between Snowdon and Édouard-Montpetit stations.
STM says Hydro-Québec will conduct preventive maintenance work on the lines powering the Blue line.
Customers are asked to plan their trips accordingly. They can monitor the status of or consult alternative transit options on the STM website.
