Ontarioville was initially the name assigned to the village of Hanover Park, a municipality situated on the border of Cook and DuPage Counties.

Luther's station kept the name Bartlett, but to avoid confusion, Edwin renamed his station "Ontario" in 1873, after a legend that the site was built on an old Indian trail between Lake Ontario and Green Bay, Wisconsin.
