Prior to being abolished, its neighbouring ridings were Papineau, Mount Royal, Saint-Laurent—Cartierville, Laval, Alfred-Pellan, Bourassa, and Saint-Léonard—Saint-Michel.

The electoral district of Ahuntsic was created in 1966 from Saint-Denis and Laval ridings.

From 1993 to 2008 Ahuntsic was usually a competitive seat between Bloc Québécois and the Liberals.

However, in 2011 Bloc Québécois incumbent Maria Mourani narrowly won reelection against a New Democratic surge that swept through Montreal and Quebec in general.

Ahuntsic was the sole seat retained by Bloc Québécois in the Montreal area and one of only four won by the party overall at the 2011 federal election.
