Montreal/Saint-Hubert Airport (IATA: YHU, ICAO: CYHU) is located in the Saint-Hubert borough of Longueuil, Quebec. The airport is located 16 km (9.9 mi) east of downtown Montreal.
In operation since 1928, it was Montreal's first and only airport until the construction of Montreal-Pierre Elliott Trudeau International Airport (formerly Montreal/Dorval International Airport). As of 2010, it is Canada's busiest general aviation airport, ahead of Toronto/Buttonville and Boundary Bay, and is ranked as Canada's 5th busiest airport by aircraft movements. This airport mainly serves travellers to Quebec destinations.
The airport is divided into two sides, a military side (facing runway 06L/24R) and a civilian side (facing runway 06R/24L). Today the military base, the former RCAF Station St Hubert, has ceased operations, but the Armed Forces still uses the base as a garrison comprising the tactical helicopter unit 438 Squadron and 51st Service Battalion.
