North Perth follows the provincially prescribed standards for winter maintenance (O. Reg. 239/02 and O. Reg. 47/13). Roads are categorized into six main classes that are based on traffic volumes and posted speed - Class 1, 2 and 3 are higher priority roads that connect to points of interest around the municipality. Class 4,5 and 6 are typically lower vlume roads that connect local neighbourhoods, farms, and businesses to major road networks. The municipality plows its roads systematically based on the classification set for each road. Further information on minimum maintenance standards can be found on the Ontario Laws website.
As the name implies, No Winter Maintenance roads receive only summer maintenance. A list of No Winter Maintenance roads in North Perth can be found in the Winter Maintenance Policy, By-law 153-2017.
