SIU Investigating After OPP Officer Fires ARWEN at Man in Oshawa Area

Case Number: 23-PFP-082   

Mississauga, ON (13 March, 2023) ---
The province’s Special Investigations Unit is investigating after an Ontario Provincial Police (OPP) officer discharged an Anti-Riot Weapon Enfield (ARWEN) at a 23-year-old man this afternoon.

Preliminary information suggests the following:
  • At approximately 1 p.m. on March 13, 2023, OPP officers were investigating the man, who was reportedly wanted on outstanding warrants.
  • Officers saw him on Highway 401 in the Oshawa area when he stopped his vehicle and left on foot. 
  • Officers pursued the man on foot and in the course of arresting him in the area of the 401 near the Farewell Street offramp, an officer discharged an ARWEN at him. The man was struck.
  • The man was taken via ambulance to hospital for assessment.
The man did not sustain any serious injury, but the SIU’s mandate was invoked because a police officer discharged an ARWEN, which is classified as a firearm. Under the Special Investigations Unit Act, a firearm is defined as a barreled weapon from which any shot, bullet or other projectile can be discharged and that is capable of causing serious bodily injury or death to a person.

The SIU is urging anyone who may have information about this investigation, including video or photos, to contact the lead investigator at 1-800-787-8529 or online at:
