History

Chemin de l'Île, the primary and only road on Cadieux Island

The island was formerly known as Vaudreuil Island but was named "Île à Cadieu" in an unpublished document of the second half of the nineteenth century. This name could be a reference to one of two Cadieux, Pierre and Hyacinthe, who owned land in the first concession along the Cove of Vaudreuil at that time.^[5]

In 1922, the municipality was formed by separating from the Parish Municipality of Saint-Michel-de-Vaudreuil.^[5]
