Our Team

Our team supports the Board’s mandate as the civilian body governing the Toronto Police Service by providing administrative, procedural and record-keeping functions. In addition, we conduct research and analysis to aid the Board’s oversight duties and create policy. We also help build relationships with diverse communities to ensure public perspectives shape policing priorities.
