List of county roads in Ontario

This is a list of County and Regional (collectively known as divisions) numbered roads in Ontario.

This page lists all of the county/district/regional roads by their respective county, district, or regional municipality.

The county road network has been present for many years, but has only been signed with the flowerpot logos since the early 1970s or 1980s (depending on the area).

However, within regional municipalities, the systems were expanded to follow major streets in the formerly separated cities, or were retained within originally-rural townships that were incorporated as cities following mass suburbanization.

Former Secondary Highway 620, downloaded to the Peterborough and Hastings County governments, was downloaded further to Wollaston Township (in Hastings County), with a posted sign appearing similar to an Ontario Tertiary Highway.
