They are Saint-Maxime and Saint-Josaphat, the two Catholic parishes that are the ancestors of Le Moyne.

Saint-Maxime has the shape of rectangle and is located from Saint-Louis Street to the limits of Greenfield Park.

Saint-Josaphat has the shape somewhat of a boomerang or a hockey stick, and is located from Sir Wilfrid Laurier Boulevard to the limits of the former city of Longueuil.
