Roadway Service Levels

We work year-round to help keep roads safe for everyone. This page explains how long it takes us to repair potholes and clear snow and ice based on road class.


Road classification and level of service

Repair timelines follow the Ontario Minimum Maintenance Standards and depend on the road class.

Ontario roads and highways are grouped into classes based on:

  • Traffic volume
  • Speed limits
  • Road size

Pothole repairs

We repair potholes after they are identified or reported. Repair times depend on the road class and the size and depth of the pothole. Learn all about potholes and how to report them on our potholes page.

Significant weather events

When a significant weather event is declared, it pauses regular winter maintenance timelines. Once the event ends, the City resumes normal service timelines.

Significant weather events affect road and sidewalk conditions. Please use extra caution when travelling.
