SIU Concludes Investigation into ARWEN Discharges at Man in Community on North Shore of St. Lawrence River

Mississauga, ON (13 July, 2025) ---
The province’s Special Investigations Unit is investigating after two Ontario Provincial Police (OPP) officers discharged Anti-Riot Weapon ENfields (ARWENs) at a 42-year-old man this morning in Morrisburg.

Preliminary information suggests the following:
  • On July 13, 2025, at about 5:13 a.m., police received a call about a man who had a gun on Augusta Street.
  • Officers located the man and attempted to negotiate. A conducted energy weapon was discharged.
  • Three was an interaction and two officers discharged ARWENs.
  • A police service dog was used and the man was handcuffed.
  • The man was taken to hospital by ambulance where he was diagnosed with a non-life-threatening serious injury.
Three investigators and two forensic investigators have been assigned to the case.

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: https://siu.on.ca/en/appeals.php

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.
