Montréal–Trudeau International Airport, formerly known and still commonly referred to as Montréal–Dorval International Airport (Aéroport international Montréal-Dorval), is an international airport in Dorval, Quebec, Canada. It is the only Transport Canada designated international airport serving Montreal and is situated 20 km (12 mi) west of Downtown Montreal. The airport terminals are located entirely in the suburb of Dorval, while one runway is located in the Montreal borough of Saint-Laurent. Air Canada, the country's flag carrier, also has its corporate headquarters complex on the Saint-Laurent side of the airport. It also serves Greater Montreal and adjacent regions in Quebec and eastern Ontario, as well as the states of Vermont and northern New York in the United States.[8] The airport is named in honour of Pierre Elliott Trudeau, the 15th Prime Minister of Canada and father of current Prime Minister Justin Trudeau.

The airport is one of two managed and operated by Aéroports de Montréal (ADM), a not-for-profit corporation without share capital; the other is Montréal–Mirabel northwest of Montreal, which was initially intended to replace the one in Dorval but now deals almost solely with cargo. Montréal–Trudeau is owned by Transport Canada which has a 60-year lease with Aéroports de Montréal, as per Canada's National Airport Policy of 1994.
