Dorval (/dɔːrˈvæl/; French: [dɔʁval]) is an on-island suburban city on the island of Montreal in southwestern Quebec, Canada.

The history of Dorval dates back more than 350 years to 1665 when Sulpician priests established a mission on the outskirts of Ville-Marie, a French settlement which later became known as Montreal.

In 1691, the domain of La Présentation, originally owned by Pierre Le Gardeur de Repentigny, was acquired by Jean-Baptiste Bouchard dit d'Orval.

[6] As with many other settlements on the island of Montreal, the Grand Trunk Railway, which came to Dorval in 1855, was highly instrumental in attracting many wealthier families, mostly English-speaking, in search of a summer refuge in proximity to their downtown residence and place of work.

This new housing consisted mostly of single family homes with some townhouses and low-rise apartment buildings, built on lands previously used for agriculture and recreational activities.

[4] According to the Office québécois de la langue française, Dorval has been officially recognized as a bilingual municipality[9] since 2005-11-02.

[19] Originally a military airfield used mainly to refuel new fighters and bombers being flown to Great Britain during the Second World War, Trudeau Airport today serves over 18 million passengers annually.
