Airport Closure Information

Last updated: Jul 25, 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.

The runway's not as bad as it looks Posted by david on October 8, 2019

The runway looks like a patchwork quilt of different shades of asphalt when you're on approach, but the surface is actually fine.

If you're VFR, note that you need to stay below 2,000 ft MSL unless you talk to Montreal Terminal (and they're often too busy to talk much, though they try to accomodate). The land is flat, there are no high towers in the area, and there are fields for emergency landing in every direction, so it's not really a problem flying around at 1,500 ft until you're out from under the class C shelf.

Great little airport Posted by thesilverflyer on March 5, 2009

just off the island of montreal, used more as a flight training school, but lots of private owners use it as well.
if you are looking to refuel fly 20mins west to cornwall regional, gas prices are cheaper because of less tax.
