List of county roads in Ontario


This is a list of County and Regional numbered roads in Ontario. These roads are found only in Southern and Southwestern 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. The signs are usually black text on white, or in some counties are multi-coloured. 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.
County roads within still-extant counties are almost always rural routes that rarely enter towns. 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.
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. Some exceptions include former Highway 38 in Eastern Ontario, where the township name appears instead of the county as the township administers the road, or is not signed at all. Former Secondary Highway 620, downloaded to the Peterborough and Hastings County governments, was downloaded further to Wollaston Township, with a posted sign appearing similar to an Ontario Tertiary Highway.
