Regional Roads

The City of Oshawa is part of a regional system of municipal government consisting of two tiers. Durham Region operates as a broader scale of government - the Regional road system provides connection to the City road system.

The Region of Durham Works Department plans, designs, builds, maintains and upgrades all roads within the Regional road system.

If you see an issue related to a Regional road, storm sewer, traffic signal or sign, you can report it to your local Region of Durham Works Department depot.
