It encompasses a portion of Quebec formerly included in the electoral districts of Brossard—La Prairie and Saint-Lambert.

[3] Brossard—Saint-Lambert was created by the 2012 federal electoral boundaries redistribution and was legally defined in the 2013 representation order.

This riding, and its predecessor, has traditionally been a Liberal bastion of support and they reclaimed it from the NDP following the 2015 federal election.

The Liberals are slightly stronger in Brossard than in Saint-Lambert, while the opposite is true for the Bloc Québécois.

Due to their recent large margins of victory in the past three elections (2015, 2019, 2021), this difference in support levels is not particularly apparent, as the Liberals have carried all or almost all polls in the riding.
