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).

History
It was originally created by the British North America Act, 1867 as Vaudreuil. 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 with Soulanges in 1914 and was re-named Vaudreuil—Soulanges.  In keeping with the usual Canadian naming practices, the appellations 'Vaudreuil' and 'Soulanges' were linked by an em-dash as the two counties remained officially separate, and their combination was for electoral purposes only. It was renamed Vaudreuil in 1966, adding a portion of the Island of Montreal and Île Bizard in the process. At the time, it was defined to consist of:
 that part of the City of Pierrefonds situated southwest of the Town of Roxboro;
 the Towns of Baie-D'Urfé, Beaconsfield, Dorion, Île-Cadieux, Île-Perrot, Kirkland, Pincourt, Pointe-du-Moulin, Rigaud, Sainte-Anne-de-Bellevue, Sainte-Geneviève and Vaudreuil;
 the Counties of Soulanges and Vaudreuil;
 the village municipality of Senneville;
 the parish municipality of Saint-Raphaël-de-l'Île-Bizard.

In 1976, it was redefined to consist of:
 the Towns of Baie-D'Urfé, Dorion, Hudson, Île-Cadieux, Île-Perrot, Kirkland, Pincourt, Pointe-du-Moulin, Rigaud, Sainte-Anne-de-Bellevue, Sainte-Geneviève and Vaudreuil;
 the Counties of Soulanges and Vaudreuil;
 the village municipality of Senneville and the parish municipality of Saint-Raphaël-de-l'Île-Bizard;
 that part of the City of Pierrefonds lying southwest of the Town of Dollard-des-Ormeaux.

In 1987, it was redefined to consist of:
 the towns of Baie-D'Urfé, Dorion, Hudson, Île-Cadieux, Île-Perrot, Kirkland, Pincourt, Rigaud, Saint-Anne-de-Bellevue and Vaudreuil;
 in the County of the Île de Montréal: the Village Municipality of Senneville;
 the counties of Vaudreuil and Soulanges.

In 1996, it was redefined to consist of:
 the cities of Dorion, Hudson, L'Île-Cadieux, L'Île-Perrot, Pincourt, Rigaud and Vaudreuil;
 the County Regional Municipality of Vaudreuil-Soulanges.

In 1997 it was renamed "Vaudreuil-Soulanges", as it had been realigned to be perfectly co-terminal to the Vaudreuil-Soulanges Regional County Municipality.

This riding lost territory to Salaberry—Suroît during the 2012 electoral redistribution and was renamed "Vaudreuil—Soulanges".

Following the 2022 federal electoral redistribution the riding will be renamed back to Vaudreuil. It will lose the municipalities of Les Cèdres and Pointe-des-Cascades to Beauharnois—Salaberry—Soulanges—Huntingdon. This will come into effect at the first election held after approximately April 2024.
