In recent electoral history, the Liberals have been dominant after taking the riding from the NDP in 2015. Their strength comes particularly from Vaudreuil, Dorion and Ile Perrot. The Bloc has its best showings in the south of the constituency, in Les Cèdres, with pockets in Vaudreuil and Rigaud. The Conservatives have also historically done relatively well, with notable showings in 2006 and 2008 (when they came second to the Bloc).
It was originally created by theBritish North America Act, 1867 asVaudreuil. It initially consisted of Isle Perrot, the Seigniories of Vaudreuil and Rigaud, and the first, second, third and fourth ranges of the Township of Newton and augmentation adjacent.
It was merged withSoulanges in 1914 and was renamedVaudreuil—Soulanges. In keeping with the usual Canadian naming practices, the appellations 'Vaudreuil' and 'Soulanges' were linked by anem-dash as the two counties remained officially separate, and their combination was for electoral purposes only. It was renamedVaudreuil in 1966, adding a portion of the Island of Montreal andÎle Bizard in the process. At the time, it was defined to consist of:
