# List of numbered roads in Peel Region

This page lists all of the numbered regional roads in Peel Region, Ontario. In December 2024, the government of Ontario tabled a bill for Peel Region to transfer all regionally-maintained and signed roads to its constituent municipalities of Mississauga, Brampton, and Caledon, which if carried out would see the decommissioning of the entire regional road system.
