Official boundary — Westmount (2004-01-14)

Westmount likely takes its name from an affluent, predominantly Anglophone, city on the west island of Montreal. The land was originally owned by Malcolm Groat and was annexed in two stages, in 1904 and 1910. Development was spurred on by the extension of the electric streetcar and its proximity to downtown.

In 1929, the community hall was moved by horse to 109A Avenue and 127 Street from outside the neighbourhood. Notably, in 1921, Westmount was one of the first communities to construct tennis courts and an outdoor rink, showcasing its commitment to recreation and community engagement.
