YMX International Aerocity of Mirabel - Extension of existing manufacturing plant

The project involves the extension of an existing aircraft engine production plant at YMX International Aerocity of Mirabel. The new extension will be integrated into an existing complex on already developed land. The structure will have an above-ground height of +/- 14m and a footprint of approximately 1,930 sq.meter.

The building extension will have a steel structure, exterior metal facing similar to the existing facing, and a rooftop covered with a white membrane to reduce heat islands. This project requires no new parking spaces



Latest update

Considering that we have not received any comments or questions and following analysis of the environmental assessment carried out by a third party, Aéroports de Montréal has determined that the project is not likely to cause significant negative effects on the environment. Mitigation measures will be taken for the following elements: vegetation, dust, residual materials. These measures are detailed as follows: planting of trees, dust suppression, recycling of construction waste.

Therefore, Pratt & Whitney can complete the project.
