SIU Investigating Police-Involved Shooting in Oshawa

Mississauga, ON (18 May, 2026) ---
The Director of the Special Investigations Unit, Joseph Martino, found no reasonable grounds to believe a Durham Regional Police officer committed a criminal offence in connection with a police-involved shooting in Oshawa. A 27-year-old man and a police officer suffered serious injuries and were treated in hospital. 

On January 18, 2026, police were called to Bloor Street East and Simcoe Street South for a man, in a mental health crisis, at a residence with a knife. Following some negotiations, the man charged at an officer with the knife. An officer discharged a conducted energy weapon before another officer shot her firearm three times. A police officer was struck in the forearm and the man with the knife was shot once in the stomach.

Director Martino found the man appeared intent on doing the officer harm with his knife and had her life was in danger. As it relates to the injuries suffered by the police officer, the officer who discharged said she was not aware that the other officer was positioned behind the man with the knife, and her account finds support in the body worn camera footage which depicts a fast-moving foot chase with multiple persons moving in various directions. In light of the highly charged atmosphere, Director Martino found the evidence fell short of reasonably establishing any criminal liability based on negligence.
