About the Riding

Notre-Dame-de-Grâce—Westmount encompasses the city of Westmount, the town of Montreal West, and the large neighbourhood of Notre-Dame-de-Grâce (NDG) in the borough of Côte-des-Neiges—Notre-Dame-de-Grâce. Westmount, with a population of approximately 19,700, is a historically wealthy and predominantly anglophone enclave that was once the richest community in Canada. NDG, home to over 70,000 people, is more diverse and has absorbed successive waves of immigration—from Eastern Europe, the Caribbean, Africa, the Middle East, and Southeast Asia.

The riding's institutional anchors include the McGill University Health Centre's Glen site (housing the Montreal Children's Hospital, the Royal Victoria Hospital, and several research institutes), Concordia University's Loyola Campus, and Marianopolis College. The Orange Line of the Montreal Metro serves the eastern edge of the riding at Villa-Maria and Vendôme stations.

The district is bilingual with a strong anglophone character. English is the mother tongue of approximately 44 percent of residents, while French is spoken by about 27 percent. The riding's median household income is well above the Montreal average, though there is significant economic diversity between the affluent streets of upper Westmount and the more modest apartment blocks of lower NDG. The Décarie Expressway bisects the riding, separating NDG to the west from Westmount and Côte-des-Neiges to the east.
