area commandAs part of the ongoing commitment to provide superior police services to the community, the Ontario Police Department has implemented a geographical based policing program. As part of this “Geo-Policing” program, the city has been drawn into three geographical areas: West, East, and South. Each area has an assigned Lieutenant as Area Commander. The Area Commander is responsible for the delivery of police services in their area of control with an emphasis on the preservation and improvement of the quality of life, safety, and economic value of those who live and do business in the city. 

Each area has dedicated teams of officers and corporals, headed by police sergeants, who work day-to-day (24/7) patrol operations; traffic officers; Community Oriented Problem Solving (C.O.P.S.) officers, who work special projects; narcotics investigators; and detectives.
