Châteauguay—Lacolle was created by the 2012 federal electoral boundaries redistribution and was legally defined in the 2013 representation order. It came into effect upon the call of the 2015 Canadian federal election.^[3]

Following the 2022 federal electoral redistribution the riding was renamed Châteauguay—Les Jardins-de-Napierville. It gained both the Village and Township of Hemmingford, and the municipalities of Très-Saint-Sacrement, Howick, Saint-Chrysostome, Havelock, and Franklin from Salaberry—Suroît and lost a small piece of territory north of Autoroute 30 in Saint-Isidore and a small piece of territory near Ch. St-Bernard in Châteauguay to La Prairie—Atateken.^[4]
