Notice of Determination

March 21, 2025 – ADM Aéroports de Montréal has determined that the project for a professional drop-off area at 800 Place Leigh-Capreol at YUL Montréal-Trudeau International Airport is not likely to cause significant adverse environmental effects by applying the mitigation measures planned for the project.

This determination was based on a consideration of the following factors:

• Technically and economically feasible mitigation measures listed below;
• Community knowledge;
• Indigenous knowledge and impacts on rights of Indigenous peoples.

The mitigation measures considered for this determination are as follows:

Air quality

• Keep trucks and all machinery in good working order.
• Equip vehicles with a functional emission control system.
• Shut down engines on gasoline-powered vehicles and equipment when not in use.
• Regularly maintain the paths used by motorized equipment and buses.

Soundscape

• Use broadband or dimmable backup alarms.
• Avoid the slamming of dump truck doors.
• Minimize the use of vehicle reverse.

Soil quality

• Cover the soil with a geomembrane in the areas intended for the storage of materials.
• Manage contaminated soil in accordance with applicable regulations.
• Segregate excavated soils according to their degree of contamination.

Groundwater and/or surface water quality

• Protect storm sewers at all times from the release of contaminants during construction.
• Ensure a spill kit is available at all times.
• Characterize the excavated water before discharge

Accordingly, ADM Aéroports de Montréal may exercise its powers to enable the project to be carried out.
