- (Population: 114,947)
- (Map 3)
Reason: It is a matter of correcting an error made when the name Châteauguay—Lacolle was attributed to this electoral district, the municipality of Lacolle being instead in the neighbouring electoral district of Saint-Jean. A public bill to this effect was passed by the Senate on February 8, 2022, but is still pending in the House. Les Jardins-de-Napierville refers to the name of the RCM of the same name that occupies a large part of the district's territory.
Consists of:
- the Regional County Municipality of Les Jardins-de-Napierville;
- that part of the Regional County Municipality of Beauharnois-Salaberry comprising the municipalities of Sainte-Martine and Saint-Urbain-Premier;
- that part of the Regional County Municipality of Roussillon comprising the cities of Châteauguay, Léry and Mercier; the Parish Municipality of Saint-Isidore;
- that part of the Regional County Municipality of Le Haut-Saint-Laurent comprising the municipalities of Franklin, Saint-Chrysostome and Howick; the Parish Municipality of Très-Saint-Sacrement; the Township Municipality of Havelock.
