Ontario Provincial Police

The Ontario Provincial Police (OPP) is the provincial police service of Ontario, Canada. Under its provincial mandate, the OPP patrols provincial highways and waterways, protects provincial government buildings and officials, patrols unincorporated areas, and provides support to other agencies.

The OPP also has a number of local mandates through contracts with municipal governments, where it acts as the local police force and provides front-line services. Within the Kitchener, Waterloo and Cambridge city limits, the OPP patrols the main north south multilane Highway 85 and highway 401.

With an annual budget of nearly $1.2 billion, the OPP employed 5,500 uniformed officers, 700 auxiliary officers, and 2,500 civilian employees in 2020, making it the largest police service in Ontario and the second-largest in Canada (after the Royal Canadian Mounted Police).
