Even before the era of provincial highway downloading in the 1990s, Ontario had its share of freeways which were not maintained by the provincial government. For example, the Don Valley Parkway in Toronto has always been a locally-maintained facility since its inception. Others, like the western end Gardiner Expressway (formerly part of the QEW) in Toronto and the eastern portion of the Queensway in Ottawa were provincial highways until 1998. All of the following freeways and parkways listed below are not maintained by the province and are the responsibility of the local units of government. Some even have unique route markers, also included below.
NOTE: Complete listings for each Municipal Freeway will be located here soon. In the meanwhile, feel free to visit the Other Highways page at the former Ontario Highways website.
