RCAF Station Lachine was a Royal Canadian Air Force station located near Lachine and Dorval, Quebec, Canada, to the west of Montreal. The location of the station was Dorval Airport, which became the Montréal-Dorval International Airport (now Montréal-Pierre Elliott Trudeau International Airport). RCAF Station Lachine began operation in 1941 as a transit point for the ferrying of aircraft and the transportation of supplies to Europe during the Second World War. Until 1943, Lachine was the location of one of five British Commonwealth Air Training Plan (BCATP) manning depots, No. 5 Manning Depot. Air Transport Command, which had been based at RCAF Station Rockcliffe, moved to Lachine in 1951. No. 426 Transport Squadron and 436 Transport Squadron were re-established at Lachine in March 1947 and April 1949 respectively. No. 426 Squadron moved to Trenton in 1959; No. 436 Squadron moved to RCAF Station Downsview in July 1956. No. 2 Air Movement Group (2 AMU) was formed at Lachine in 1951 and provided support to these squadrons. Air Transport Command moved to Trenton in September 1959 when the station closed.

The West Island (French: l'Ouest de l'île) is the unofficial name given to the city, towns and boroughs at the western end of the Island of Montreal, in Quebec, Canada. It is generally considered to consist of the Lakeshore municipalities of Dorval, Pointe-Claire, and Beaconsfield, the municipalities of Kirkland, Dollard-des-Ormeaux, Baie-D'Urfé, Sainte-Anne-de-Bellevue, the village of Senneville, and two North Shore boroughs of the city of Montreal: Pierrefonds-Roxboro and L'Île-Bizard–Sainte-Geneviève. Historically, there was a linguistic division of the island of Montreal into French and English 'halves', with Francophones typically inhabiting the eastern portion of the island and Anglophones typically inhabiting the western half. The West Island's population is approximately 234,000 and although the overwhelming majority of its residents are today bilingual if not multi-lingual (given the cosmopolitan nature of this vast suburban area), anglophones still make up a plurality of the West Island's population. As late as the 1960s, much of the West Island was farmland populated by French Canadians, which in turn accounts for a significant Francophone cultural influence in the region. The region is home to the Montréal–Trudeau International Airport, John Abbott College, Cégep Gérald-Godin, the Macdonald Campus of McGill University, the Fairview Pointe-Claire and Galeries des Sources malls, as well as Montreal's largest park, the Cap-Saint-Jacques Nature Park. Hospitals include the Veteran's Hospital in Sainte-Anne's and the Lakeshore General Hospital in Pointe-Claire. Municipalities range in character from the modern bedroom communities of Kirkland or Dollard-des-Ormeaux to the former cottage-country homes of Dorval, Pointe Claire and Beaconsfield. Development and the concentration of industrial activity along highways 20, 40 and 13 over the last twenty years has made securing the region's remaining tracts of open land a priority for many West Island residents. The West Island is home to one of the last large remaining tracts of Montreal-region wilderness on island.
