There are three agencies that oversee different areas relating to police services.

The OIPRD is responsible for ensuring that the public complaints system works for all Ontarians – both the community and the police. The OIPRD will intake, process and, in some cases, investigate complaints against municipal, regional and provincial police services in Ontario. We also provide training, outreach and education on the public complaints system.

The Special Investigations Unit (SIU) is a civilian law enforcement agency with a consequence-based jurisdiction to conduct criminal investigations. The SIU investigates incidents involving the police and civilians that have resulted in a serious injury, death or allegations of sexual assault. For more information about the SIU, please visit

The Ontario Civilian Police Commission (OCPC) is an independent oversight agency committed to serving the public by ensuring that adequate and effective policing services are provided to the community in a fair and accountable manner. For more information about the OCPC, please visit
