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.

Which 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.
