Airport Closure Information

Last updated: Nov 21, 2025
Closure Date

September 30, 2017

Reason for Closure

Economic reasons. The airport was privately owned and was sold to the real estate developer Groupe Montoni in 2016. The land's value for industrial development, given its strategic location near major highways (Autoroute 30), far exceeded its profitability as a general aviation airport. The developer's plan was to demolish the airport and build a large-scale logistics and industrial park.

Current Status

The airport site has been completely transformed. Following its closure, all airport infrastructure, including runways, taxiways, and hangars, was demolished. The developer, Groupe Montoni, has since built the 'Logistis Montoni - Pôle 30' on the land. It is now a major industrial and logistics park housing large warehouses and distribution centers for various companies, taking advantage of the site's prime location for transportation and shipping.

Historical Significance

Montreal / Les Cèdres Airport (TC LID: CSG3) was a crucial general aviation hub for the Greater Montreal area for several decades. It served as a reliever airport, alleviating traffic from the main Montréal–Trudeau International Airport (CYUL) by accommodating flight training, private aircraft, and small charter operations. Its most notable tenant was Laurentide Aviation, one of Canada's oldest and most respected flight schools, founded in 1946. Laurentide had moved to Les Cèdres from the now-closed Cartierville Airport in the 1980s, and the closure of Les Cèdres forced them to relocate once again, this time to Salaberry-de-Valleyfield Airport (CSD3). The airport featured two paved runways (05/23 and 11/29) and was a vibrant community for pilots, aircraft maintenance engineers, and aviation enthusiasts.

Reopening Prospects

There are no prospects for reopening the airport. The land has been permanently and fully redeveloped for industrial use. The construction of massive, permanent structures on the former airfield makes any return to aviation operations impossible.
