Montreal Underground City map
The City of Montréal describes the RÉSO as about 32 km of pedestrian galleries. No single map shows every door and level. Use a map to see what connects, then follow signs on site.
Open interactive guideWhich map to use
The City’s RÉSO page links to its network plan. That plan dates from 2017, and it still shows a Bell Centre link from Bonaventure that the Bell Centre now lists as closed. The STM neighbourhood maps are newer (2024–2026) and show the indoor network around each station. Check the date printed on any map you use.
What the planner adds
WalkUnderMTL routes between named landmarks: métro stations, malls, food halls, hotels and venues. It lists the sources behind each route and warns when a passage may close off hours. It does not show exact turns, levels or step-free paths.
- McGill métro to Place Ville Marie (about 3 min)A short first walk.
- Gare Centrale to the Palais des congrès (about 14 min)Crosses the Quartier international.
Before you go
- Shops are routed to their mall unless the planner marks an exact stop.
- Follow RÉSO and building signs at each link; they beat any map.
- If a door is closed, use the street. Building hours vary.
