Arterial: For major and collector roads and major rural roads, the centre of road will be essentially clear as soon as possible after snowfall ends and, normally, within four hours. The Downtown Kingston Business Improvement Area falls within this top priority.
Collector and transit routes: For secondary collector roads and transit routes, the centre of road will be essentially clear as soon as possible after snowfall ends and, normally, within six hours.
Residential: Local residential, commercial areas and minor hard-surfaced rural roads will be essentially cleared as soon as possible after snowfall ends and, normally, within 16 hours.
