The Proposed Project

The Project aims to develop new drop-off areas and a new multi-level parking structure to improve passenger access to Montréal-Trudeau Airport (YUL).

The Project includes the following activities:

1. Demolition of the existing multi-level parking structure, which has reached the end of its service life;
2. Construction of a new nearby multi-level parking structure (P5) connected to the REM station and the terminal building;
3. Installation of a retention basin under the new parking structure to improve stormwater management;
4. Development of additional drop-off areas, notably south of the current parking structure, to facilitate vehicular circulation within airport grounds;
5. Construction of pedestrian overpasses allowing users to walk freely between the drop-off areas, parking facility, REM airport station, and the terminal.

Work is scheduled to begin in November 2025 with the demolition of the current multi-level parking structure. The total duration of the Project, including phases still being planned, is approximately six years.
