Construction and Resurfacing

Maintaining 877 kilometres of County roads is no small task. Each year, millions are invested into our roads to ensure they are safe for travelers throughout the region.

Construction Maps

The Planned Construction and Resurfacing Map shows tentative road and structure replacement (bridges and culverts) projects planned for the year. The 10-year plan shows which projects are planned over the next decade. These projects are subject to Council approval. Priority may change based on conditions of the roads.

Grey County also adds planned and active construction to our interactive map. Click on active projects to learn more about the scope and timing of the projects.

Grey County is committed to keeping our roads safe. We actively patrol roads to spot issues and make timely repairs. Sometimes potholes can develop quickly, especially early in the spring.

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

  • Email: roads [at] grey.castyle="color:blue; text-decoration:underline"
  • Phone: 519-373-7337
  • Online Form: Available on

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. 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 cmon 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.
