History
Ontarioville was initially the name assigned to the village of Hanover Park, a municipality situated on the border of Cook and DuPage Counties. Back in 1836, a stagecoach service transported residents along Lake Trail (also known as Grant Highway and later renamed Lake Street) all the way to Galena. By 1872, the Chicago & Pacific Railroad (later known as the Chicago, Milwaukee & St. Paul) installed railway tracks on land donated by Edwin Bartlett, who contributed over seven acres for the establishment of a depot. Edwin and Luther Bartlett each established stations named "Bartlett" along the Chicago and Pacific Railroad line. 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.
A post office was established in Ontarioville in 1873.
Ontarioville was eventually incorporated into the surrounding village of Hanover Park in 1982.
