Bryan Larkin will take the helm of the Waterloo Regional Police on August 31, according to a release from the police services board.
Larkin is taking over after former Chief Matt Torigian announced his retirement from the force in April.
Torigian left the force to take up a new role as Deputy Minister of Community Safety and Correctional Services with the Ontario government.
Waterloo Region Police Serivces Board Chair Tom Galloway said Tuesday Larkin was able to negotiate an earlier release from his duties as chief of Guelph police.
Larkin was chief in Guelph for two years, and before that spent a year as the deputy chief of the city's police force.
Earlier this month, Larkin told Craig Norris on The Morning Edition that he wants to make Waterloo Regional Police the "best police service in Ontario."
