SIU Director’s Report - Case # 23-OFP-268
This page contains graphic content that can shock, offend and upset.
Mandate of the SIU
Under the SIU Act, the Director of the SIU must determine based on the evidence gathered in an investigation whether there are reasonable grounds to believe that a criminal offence was committed. If such grounds exist, the Director has the authority to lay a criminal charge against the official. Alternatively, in cases where no reasonable grounds exist, the Director cannot lay charges. Where no charges are laid, a report of the investigation is prepared and released publicly, except in the case of reports dealing with allegations of sexual assault, in which case the SIU Director may consult with the affected person and exercise a discretion to not publicly release the report having regard to the affected person’s privacy interests.
Special Investigations Unit Act, 2019Pursuant to section 34, certain information may not be included in this report. This information may include, but is not limited to, the following:
- The name of, and any information identifying, a subject official, witness official, civilian witness or affected person.
- Information that may result in the identity of a person who reported that they were sexually assaulted being revealed in connection with the sexual assault.
- Information that, in the opinion of the SIU Director, could lead to a risk of serious harm to a person.
- Information that discloses investigative techniques or procedures.
- Information, the release of which is prohibited or restricted by law.
- Information in which a person’s privacy interest in not having the information published clearly outweighs the public interest in having the information published.
Freedom of Information and Protection of Privacy ActPursuant to section 14 (i.e., law enforcement), certain information may not be included in this report. This information may include, but is not limited to, the following:
- Confidential investigative techniques and procedures used by law enforcement agencies; and
- Information that could reasonably be expected to interfere with a law enforcement matter or an investigation undertaken with a view to a law enforcement proceeding.
- The names of persons, including civilian witnesses, and subject and witness officials;
- Location information;
- Witness statements and evidence gathered in the course of the investigation provided to the SIU in confidence; and
- Other identifiers which are likely to reveal personal information about individuals involved in the investigation.
Personal Health Information Protection Act, 2004Pursuant to this legislation, any information related to the personal health of identifiable individuals is not included.
Other proceedings, processes, and investigationsInformation may also have been excluded from this report because its release could undermine the integrity of other proceedings involving the same incident, such as criminal proceedings, coroner’s inquests, other public proceedings and/or other law enforcement investigations.
A person sustains a “serious injury” for purposes of the SIU’s jurisdiction if they: sustain an injury as a result of which they are admitted to hospital; suffer a fracture to the skull, or to a limb, rib or vertebra; suffer burns to a significant proportion of their body; lose any portion of their body; or, as a result of an injury, experience a loss of vision or hearing.
In addition, a “serious injury” means any other injury sustained by a person that is likely to interfere with the person’s health or comfort and is not transient or trifling in nature.
This report relates to the SIU’s investigation into the discharge of a firearm by the police at a 22-year-old man (the “Complainant”).

Video/Audio/Photographic Evidence 
911 CallOn July 14, 2023, a woman called 911 to request an ambulance at a residence in Oakville. She advised that the Complainant was having a mental health crisis. She could be heard yelling, “Run, run, run, get in the car.” She told the dispatcher that she was in the car and was trying to leave the residence. The caller had gone into the house to get a family member out. The Complainant had a history of mental health breakdowns. She last saw him coming down the stairs with a knife and bear spray in his hands. He did not recognize her and could not communicate with her. The caller believed her parents were hiding in a room on the main floor.

In the evening of July 13, 2023, HRPS officers were dispatched to a house in Oakville. Members of the Complainant’s family had called 911 reporting concern for the welfare of the Complainant. The Complainant was in mental health crisis. When he took possession of a knife and bear spray, the other members of the family fled the residence.
Uniformed officers arrived and confronted the Complainant. As he still had possession of the weapons, they withdrew and set up containment around the house. Efforts to communicate with the Complainant were to no avail.
The HRPS TRU team was mobilized and gathered at the residence, taking charge of the police presence outside the home. They too attempted to reach the Complainant via phone, social media, and loud hailer. They called-out to the Complainant directing him to exit the house without any weapons and assuring him they were there to help. From positions outside the home, officers made observations of the Complainant. He paced around the house and continued to carry the knife and bear spray.
At about 2:45 a.m., July 14, 2023, the critical incident commander – WO #6 – authorized the TRU entry into the home following consultations with a forensic psychiatrist. When a key to the front door that had been provided police by the Complainant’s family failed to work, TRU officers forced open the front door. Several metres into the home, officers observed the Complainant still holding the knife and bear spray. The officers maintained their distance from outside the home and watched as the Complainant moved into the living room.
The Complainant was removed from the scene in ambulance and taken to hospital.
Section 25(1), Criminal Code -- Protection of persons acting under authority
(a) as a private person,(b) as a peace officer or public officer,(c) in aid of a peace officer or public officer, or(d) by virtue of his office,
Analysis and Director's Decision
Pursuant to section 25(1) of the Criminal Code, police officers are immune from criminal liability for force used in the course of their duties provided such force was reasonably necessary in the execution of an act that they were required or authorized to do by law.
The Complainant was subject to apprehension under the Criminal Code and the Mental Health Act by the time of the SO’s ARWEN discharges. While of unsound mind brought about by mental illness, he had brandished a knife and bear spray at his parents, and cut himself while punching a glass door.
With respect to the force used by the SO in aid of the Complainant’s arrest, namely, six ARWEN discharges delivered in two volleys, I am satisfied that it was legally justified. The officer would have known that the Complainant had been seen with a knife and bear spray. He would also have known that the Complainant had earlier threatened his parents with the weapons and there was concern that he might engage in self-harm. It appears the SO acted reasonably when he attempted to temporarily incapacitate the Complainant from a safe distance with his ARWEN. Had the ARWEN worked as designed, the pain caused by impact would have sufficiently distracted the Complainant allowing for other officers to safely approach and restrain him. The second volley, when the first did not work, can be justified for similar reasons. At the time, the officers would still have been concerned that the Complainant had access to the knife and bear spray. In the circumstances, they were within their rights in attempting to momentarily neutralize the Complainant before approaching and potentially placing themselves in harm’s way. The fact that the further ARWEN rounds failed to fell the Complainant, which only happened after a CEW discharge, is further indication that the SO did not act with excess when he fired his weapon.
In the result, as there are no reasonable grounds to conclude that the SO comported himself other than within the limits of the criminal law when he fired his ARWEN, there is no basis for proceeding with charges in this case. The file is closed.
