History

The municipality is named after the old Mille-Isles Seigneury, which originally straddled the Mille Îles River (the seigneury uses the old spelling, whereas the river uses the modern word that substitutes a circumflex for the "s"). In 1683, the seigneury was granted to Michel-Sidrac Dugué de Boisbriand (circa 1638-1688), who was governor of Montreal in 1670. In 1714, it was inherited by Charles-Gaspard Piot de Langloiserie (circa 1655-1715) and Jean Petit (1663-1720), husbands of Marie-Thérèse Dugué and Charlotte Dugué respectively, daughters of the first lord. In 1752, additional land in the extreme north-west of the Mille-Isles Seigneury was given to Eustache Lambert Dumont and it is within this part that the municipality is located.^[4]

The first settlers were from Ireland and arrived around 1850. The municipality was officially founded in 1855, following separation from the parish of Saint-Jérôme.^[4]
