Papineau (electoral district)

Papineau (French pronunciation: [papino]; formerly Papineau—Saint-Denis and Papineau—Saint-Michel) is a federal electoral district (riding) in Montreal, Quebec, Canada, that has been represented in the House of Commons since 1948. Its population in 2016 was 110,750. Justin Trudeau, the former Prime Minister of Canada and former leader of the Liberal Party, represented the riding from the 2008 federal election until he resigned in 2025. Trudeau became Liberal leader in a 2013 leadership election, succeeding Bob Rae, and prime minister when the Liberals returned to government in the 2015 Canadian federal election, succeeding Conservative leader Stephen Harper.

The name of the riding comes from a street in the Villeray neighbourhood, named after Joseph Papineau.

At nine square kilometres (3.5 square miles), it covers the second smallest area of any federal riding in Canada after Toronto Centre. Linguistically, 45% of residents list French as their mother tongue, 8% list English, and 47% list neither English nor French, with large groups speaking Spanish, Italian, Urdu, Hindi, Punjabi, Pashtu, Bengali, Greek, and Arabic. Immigrants make up 40 percent of the riding's population.
