The chief of York Regional Police is retiring this summer.

Chief Jim MacSween announced on Thursday that his retirement will take effect on June 26.

“It has been the greatest honour of my career to lead the dedicated members of York Regional Police, who put the professionalism, compassion and commitment to public safety into action every day,” MacSween said in a post on social media.

“Being privileged to work alongside and lead thousands of exceptional people, I am retiring with immense gratitude and pride.”

MacSween, who took over the chief role on May 1, 2020, said he is committed to supporting a seamless transition.

He began his career with YRP in 1989 and held a number of roles within the service, including serving as the officer in charge of two police districts and as superintendent of operational command.

York Regional Police Service Board (YRPSB) said it has begun work on identifying and appointing the next chief of police.

“On behalf of the Board, I want to extend our sincere congratulations to Chief MacSween on his well-earned retirement after dedicating 37 years to policing, including the past six as chief of police,” YRPSB Chair Steve Pellegrini said in a statement.

“Chief MacSween has served our community with integrity, professionalism and a steadfast commitment to public safety.”

The union representing YRP officers congratulated MacSween following the announcement.

“He led the service through evolving changes that required integrity, resilience and a genuine care for both members and the public. We are grateful for his leadership and wish him all the best in his retirement.”

MacSween’s announcement comes weeks after YRP announced the results of their bombshell investigation into Toronto police corruption, which resulted in seven current officers being charged.
