SIU Completes Investigation into Peel Officer Who Shot Man with ARWEN at Mississauga Hospital

Case Number: 21-OFI-400   

Mississauga, ON (24 March, 2022) ---
The Director of the Special Investigations Unit, Joseph Martino, has found no reasonable grounds to believe that a Peel Regional Police officer committed a criminal offence in connection with the injury of a 43-year-old man in the course of his arrest in Mississauga in November.

On November 23, 2021, officers responded to a bomb threat made in the emergency department at Mississauga Hospital on the Queensway. In an attempt to arrest the man responsible, an officer shot the man with four Anti-Riot Weapon Enfield rounds. 

While Director Martino accepted that an ARWEN projectile broke the man’s arm, there were no reasonable grounds to believe that the officer comported himself other than lawfully in the incident.

Full Director’s Report (with Incident Narrative, Evidence, and Analysis & Director’s Decision): 


The SIU is an independent government agency that investigates the conduct of officials (police officers as well as special constables with the Niagara Parks Commission and peace officers with the Legislative Protective Service) that may have resulted in death, serious injury, sexual assault and/or the discharge of a firearm at a person. All investigations are conducted by SIU investigators who are civilians. Under the Special Investigations Unit Act, the Director of the SIU must

  • consider whether the official has committed a criminal offence in connection with the incident under investigation
  • depending on the evidence, cause a criminal charge to be laid against the official where grounds exist for doing so, or close the file without any charges being laid
  • publicly report the results of its investigations
