Westmount is an affluent on-island suburb on the Island of Montreal. It is an enclave of the city of Montreal, in southwestern Quebec, Canada, with a population of 19,931 as of the Canada 2011 Census.
Westmount is home to schools, an arena, a pool, a public library and a number of parks, including Westmount Park, King George Park (also known as Murray Hill Park) and Westmount Summit. The city operates its own electricity distribution company Westmount Light & Power (Hydro-Westmount). The city is also the location of two Canadian Forces Primary Reserves: The Royal Montreal Regiment and 34th Signals Regiment.
Traditionally, the community of Westmount was an enclave of wealthy anglophones, having been at one point the richest community in Canada. It now competes with Rockliffe Park in Ottawa, West Vancouver outside of Vancouver, Lawrence Park, Forest Hill, Rosedale, and The Bridle Path, all in Toronto, for the title.
