SIU Investigating After Halton Officers Shoot Less-Lethal Shotgun, ARWEN at Man in Milton

Case Number: 23-OFP-031   

Mississauga, ON (30 January, 2023) ---
The province’s Special Investigations Unit is investigating after Halton Regional Police Service officers shot a less-lethal shotgun and Anti-Riot Weapon Enfield (ARWEN) rounds at a 43-year-old man in Milton early this morning.

Preliminary information suggests the following:
  • At approximately 1:10 a.m. on January 30, 2023, officers were called to an apartment on Bronte Street South for a disturbance.
  • Officers attempted to negotiate with the man and attempted to apprehend him under the Mental Health Act. The man exited his apartment with a weapon. One officer discharged a less-lethal shotgun round at the man. The man went back inside his apartment. 
  • Officers attempted to negotiate with the man without success. Officers entered the apartment and another officer discharged an ARWEN multiple times at the man. 
  • The man was apprehended and taken to hospital.
  • He was not seriously injured.
Three investigators and three forensic investigators have been assigned.

The man was not seriously injured, 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:
