Road Jurisdiction

There are four types of road systems located in Grey County.

  • Provincial Highways
  • County Roads
  • Local Municipal Roads
  • Private roads

Provincial Roads

There are five major highways in Grey County: 6, 10, 21, 26 and 89. These roads are the responsibility of the Ministry of Transportation. Questions can be directed to the Owen Sound office at 519-376-7350.

County Roads

County roads are the responsibility of Grey County and are named numerically (Grey Road 1, Grey Road 2 etc).  Questions related to Grey County roads should be directed to 519-376-7337 or submitted by e-mail.

Local Municipal Roads

Local roads are the responsibility of Grey County’s nine member municipalities. Local roads have common names such as Henry Street, Concession 1, 3rd Line etc. For questions related to these roads, contact the local municipality.

Private Roads

Private roads are owned and maintained by individuals, groups of property owners, or businesses.  These are normally found in private developments, waterfronts or cottages.

Road Salt Management

Grey County winters can be challenging. Fortunately, County staff have the knowledge and technology needed to keep roads safe and respect the environment.

Here’s how Grey County uses road salt to melt ice during the winter.

  • All plows are equipped with special electronic controls that regulate how much salt is applied to the road.  Plow operators set these controls based on the current weather and road conditions so salt is applied efficiently.
  • All salt is treated with a liquid deicer so it works faster and at colder temperatures. It also helps salt stick to the road better when it lands and leaves behind a residue that prevents more snow and ice from forming.
  • Rubber mounted blades on plows clean road surfaces more aggressively so less salt is needed.
  • Every plow has a GPS to track salt usage and ensure it is being applied correctly.

The amount of salt used each year depends on weather conditions.  It can vary from as little as 10,000 tonnes to more than 18,000 tonnes. Grey County works hard to meet the minimum maintenance standards set by the Ministry of Transportation, and service the levels approved by Grey County Council. We will continue to explore new technologies to improve our salt management plan and practices.

Adopt a Road Program

*The Grey County Adopt a Road Program is on hold due to COVID-19. Grey County will consider resuming the program in the fall of 2021. Please check this page for updates.

The Grey County Adopt A Road Program is a public service program where volunteers to pick up litter along County road sides. It is a way for environmentally conscious citizens, community groups, private businesses and industries to contribute to a cleaner and more beautiful Grey County. In addition to a cleaner environment, volunteers and organizations are recognized through signs along the roadside.

Road and volunteer safety is of primary importance in all County decisions related to the Adopt A Road program. Please read the “Adopt a Road” Procedure and then download and fill out and send us the “Adopt a Road” Agreement.

School Spring Litter Pick-up

The School Litter Pick-up Program helps keep Grey County roadsides clean while teaching young people environment responsibility. Students learn to work together to help the environment and support their communities.  As a bonus incentive, Grey County gives a donation to the school for every kilometre of roadside cleaned. 

Safety is top priority. Grey County will ensure participants are given, understand and comply with training and safety requirements.

Construction and Resurfacing

The Construction and Resurfacing Map shows tentative road and structure projects for the next ten years. This map is for planning purposes only.  All projects are subject to County Council approval and priority may change based on condition of the roads.

Grey County is committed to keeping our roads safe for travelers. Grey County actively patrols roads to spot issues and make timely repairs, but sometimes potholes can develop quickly.

If you see a pothole on a County road that you believe needs repairs, you can report it by:

            Phone: 519-376-7337
            Email: roads@grey.ca
            Online Form: Available on Grey.ca

Please note that by reporting a pothole, you are not submitting a claim to the County.   


What causes a pothole?

Potholes are generally caused by significant freeze/thaw weather cycles that damage the road surface. During these freeze/thaw cycles, water seeps into cracks in the asphalt. Changes in the temperature and the vibration from vehicles, especially heavy vehicles, causes stress on the road which can then deteriorate and create a pothole.


Repairing potholes and meeting Minimum Maintenance Standards

Although we try to fix damage as soon as possible, Provincial “Minimum Maintenance Standards” define how quickly repairs must be completed. The timing depends on the size of the pothole and the classification of the road. The Standards may be changed by the Province, but as of March 2019, they say:

  • Potholes must be at least 800 cm2 on class 2 roads or 1000 cm2 on Class 3&4 roads and at least 8 cm deep to be considered in a “state of disrepair”.
  • Potholes on higher speed roads and high-volume roads will be repaired within four days of being observed or reported.
  • Potholes on lower speed and volume roads will be repaired within 14 days.

Grey County regularly exceeds the Minimum Maintenance Standards.


Damage Claims

Grey County strives to repair road surface damage quickly and will not be held responsible for damage to vehicles or property if Provincial “Minimum Maintenance Standards for Highways” have been met. These standards are laid out in Ontario Regulation 239/02, issued by the Province under the Municipal Act S.O. 2001, c. 25, outlined above. 

Tree Cutting and Brushing

Grey County inspects trees and plant growth on our roads annually. Dead or dying trees, severely damaged trees and hazardous trees are flagged for removal to avoid personal injury and property damage.

Brushing operations are scheduled for various locations to help control growth that may make it hard to see. Brushing also helps with drainage and creates more space where snow is stored.

If you have questions about tree cutting or brushing, contact us roads.grey.ca or call 519-376-7337.

Significant Weather Event

Grey County may declare a significant weather event if the current or forecast weather conditions could make County roads dangerous to road users. Although this is most likely to happen during the winter season, a significant weather event could be declared any time of year.

The declaration of a significant weather event isn’t a notice of reduced service levels or a road closure. It is a warning that it may take longer than usual to bring the roads back to optimal conditions. Road users should consider this warning when deciding whether to travel.


Posting significant weather events

When a significant weather is declared, Grey County will inform the local media and will give notice on:


Update messages will be posted as necessary and when the significant weather event is declared over.


Declaring significant weather events is permitted under the Minimum Maintenance Standards.
