"In this article, I review debates about relations between police chiefs and their governing authorities in Ontario over the last 70 years, beginning with the enactment of the Ontario Police Act in 1946, through its replacement by the Ontario Police Services Act in 1990, to the enactment of a new Police Services Actin 2018. I discuss how the respective roles and responsibilities of municipal and regional police chiefs and their police governing authorities, and the relationships between them, have evolved and changed over this period."
