List of county roads in Ontario
This is a list of County Numbered roads in Ontario. These roads are found only in Southern and Southwestern Ontario (with the lone exception being Greater Sudbury, which is in Northern Ontario), and are listed alphabetically by county, because more than one county can sometimes have the same county road number without connecting across county lines.
By their nature, all county roads in Ontario are numbered, unless noted. This page lists all of the county/district/regional roads by their respective county, district, or regional municipality.
Some counties have been merged in the past, and are known as "United Counties". They will be treated and named as one county.
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). Previously, the roads simply had road names, such as "Essex Road 42" or "Kent County Road 14", and so on, but had no shields to designate them.
In addition to County Roads, many townships also have Concession roads and Township Roads, such as Colchester South Road 3, and Concession 8. These do not have shields (only names on signs and maps), aside from one exception: Former Highway 620. It was downloaded to the Peterborough and Hastings County governments, and in one section, the highway was downloaded further to Wollaston Township (in Hastings County), and is now signed as "Wollaston Township 620", with a municipal sign similar to an Ontario Tertiary Highway.
