While the repair work is under way, métro trains will transit through Côte-Sainte-Catherine station at low speed without stopping. STM will implement a shuttle bus service running every five to eight minutes, during metro operating hours, between Snowdon, Côte-Sainte-Catherine and Plamondon stations, in both directions.
For the duration of the repairs, the corridor below boulevard Côte-Vertu will remain open so that clients may exit from the open entrance building. For each one of the entrance buildings, repairs will consist mainly of demolishing the entrance building's structural slab and pouring a new one, with the addition of a waterproofing membrane, repairing staircases and floor finishes, installing new windows, replacing the entrance building's indoor and outdoor lighting, replacing the fire protection system, as well as resurfacing the asphalt and some outdoor landscaping.
The repair work is part of phase II of the Réno-Stations Programme. Transport Québec and STM are financial partners in carrying out this program.
