Mandate of the SIU
The Special Investigations Unit is a civilian law enforcement agency that investigates incidents involving an official where there has been death, serious injury, the discharge of a firearm at a person or an allegation of sexual assault. Under the Special Investigations Unit Act, 2019 (SIU Act), officials are defined as police officers, special constables of the Niagara Parks Commission and peace officers under the Legislative Assembly Act. The SIU’s jurisdiction covers more than 50 municipal, regional and provincial police services across Ontario.
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.

Information 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.
Mandate Engaged
Pursuant to section 15 of the SIU Act, the SIU may investigate the conduct of officials, be they police officers, special constables of the Niagara Parks Commission or peace officers under the Legislative Assembly Act, that may have resulted in death, serious injury, sexual assault or the discharge of a firearm at a person.
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 60-year-old man (the “Complainant”).
The Investigation
Notification of the SIU[1]
On April 4, 2025, at 10:20 p.m., the Ontario Provincial Police (OPP) contacted the SIU with the following information.
On April 4, 2025, a resident of an address in Severn Township (Residence #1) contacted the OPP to report the Complainant threatening residents in the area with a knife. The Complainant was intoxicated and had set fire to various homes and structures. He had been temporarily residing at Residence #2, before being requested by the owner to leave. In response, the Complainant set fire to Residence #2, Residence #3 and, possibly, Residence #4. When OPP officers arrived, the Complainant was located in the yard of Residence #2, where attempts to negotiate his surrender were made. A Conducted Energy Weapon (CEW) was deployed followed by an Anti-riot Weapon Enfield (ARWEN) discharge, allowing officers to gain control of the Complainant. Although believed uninjured, he had been taken to Orillia Soldiers’ Memorial Hospital (OSMH) for examination.

Video/Audio/Photographic Evidence[3]
OPP Body-worn Camera (BWC) Footage
On April 4, 2025, at 8:52:25 p.m., police officers located the Complainant standing behind a shed at Residence #2. They shouted at him to not move, show his hands, and get on the ground. The Complainant responded, “No. No, I’m not.” He bent over, placed both hands on the ground, and then returned to a standing position and took several steps towards them.
At 8:52:39 p.m., the SO discharged an ARWEN striking the Complainant in the abdomen. Simultaneously, WO #2 deployed a CEW, which did not appear to be effective. A second CEW deployment by WO #2 resulted in neuromuscular incapacitation, and the Complainant fell chest first into a snowbank. The Complainant’s hands were under his chest, and he was directed repeatedly to show them. He rolled onto his right side when WO #2 discharged his CEW a third time. Officers were positioned at the Complainant’s back and struggled to get his arms from under his body to behind his back.[4]
At 8:53:53 p.m., the Complainant was handcuffed behind his back.
OPP Communications Recordings – Telephone
On April 4, 2025, at 8:30 p.m., Homeowner #1 of Residence #1 called the Provincial Communications Centre and reported his neighbour, the Complainant, trying to burn his house down with five-gallon gasoline containers. It exploded on his front step, and everything was on fire. He had caught the Complainant pouring gasoline on his step but would not confront him. Multiple homes were on fire. The Complainant was a disgruntled tenant of Homeowner #2, and the neighbours were having trouble with him. Homeowner #2’s house was one of three houses on fire.
At 8:31 p.m., Homeowner #3 of Residence #3 called the OPP advising that the Complainant had set her and her neighbour’s homes on fire. The Complainant lived in the garage at Residence #4. They had filed a complaint, and that was why he was throwing gasoline on their house. CW #1 in the same phone call indicated they did not know where the Complainant was, but he was dangerous and had a knife. He had fought with the Complainant.
OPP Communications Recordings - Radio
On April 4, 2025, at 8:32 p.m., OPP officers were dispatched to Residence #1, where a neighbour [the Complainant] was attempting to burn down a house. There were multiple houses on fire and the Complainant had emptied five-gallon gasoline containers around the property. The Complainant had fought with one of the homeowners and fled. A physical description was provided, and he was said to be on foot and carrying a knife.
At 8:39 p.m., the Complainant was said to be attempting suicide by laying on top of a knife in front of Residence #3.
At 8:40 p.m., the Complainant was reportedly walking to Residence #4.
At 8:45 p.m., police officers arrived.
At 8:49 p.m., another building was being lit on fire.
At 8:51 p.m., Officer #1 was on the opposite side of the Severn River, and the Complainant was said to be near a shed with a lighter behind a fully engulfed building.
At 8:53 p.m., the Complainant was reported to be in custody.

Incident Narrative
The evidence collected by the SIU, including interviews with the Complainant and police and non-police witnesses, and video footage that largely captured the incident, gives rise to the following scenario. As was his legal right, the SO chose not to interview with the SIU or authorize the release of his notes.
In the evening of April 4, 2025, OPP officers were dispatched to a residential area in Gravenhurst following calls to police from several homeowners. It was reported that a disgruntled Complainant had set fire to a number of residences. One of the homeowners, CW #1, had discovered the Complainant in the act, and the two had exchanged blows before the Complainant produced a long knife and CW #1 retreated to safety.
The Complainant had in recent months been living unlawfully in the area, first in a trailer on the property of Residence #2, then in the garage of Residence #4. Informed by by-law enforcement officers that his living accommodations were unlawful, and directed to vacate, an angry Complainant had resolved to destroy the homes of those he blamed for his predicament. He poured gasoline on several properties and set fire to Residence #2 and Residence #4 before he was confronted by OPP officers in the backyard of Residence #2, which backed onto a body of water.
OPP officers, including the SO, armed with an ARWEN, and WO #2, with a CEW at the ready, directed the Complainant to the ground in the area of a shed in the backyard. The Complainant refused and, instead, began to advance towards the officers. He was simultaneously tasered by WO #2 and struck by an ARWEN round fired by the SO. When neither discharge seemed to deter the Complainant, he was tasered a second time by WO #2. On this occasion, the Complainant locked-up and fell to the ground. Following a physical engagement on the ground between the Complainant and several officers, and several more CEW discharges by WO #2, the Complainant was handcuffed behind the back. He had not suffered any serious injuries.
Relevant Legislation
Section 25(1), Criminal Code - Protection of Persons Acting Under Authority
25 (1) Every one who is required or authorized by law to do anything in the administration or enforcement of the law
(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,
is, if he acts on reasonable grounds, justified in doing what he is required or authorized to do and in using as much force as is necessary for that purpose.
Analysis and Director’s Decision
The Complainant was struck by an ARWEN round fired by an OPP officer on April 4, 2025. The SIU was notified of the incident and initiated an investigation, naming the SO the subject official. The investigation is now concluded. On my assessment of the evidence, there are no reasonable grounds to believe that the SO committed a criminal offence in connection with the use of the ARWEN.
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.
Based on the information received via the 911 calls of the arsons being committed by the Complainant, and what they gathered directly of the fires once on scene, I am satisfied that the involved officers, including the SO, were within their rights in seeking to take him into custody.
I am further satisfied that the SO used only reasonable force in aid of the Complainant’s arrest. At the time, the officer had reason to believe that the Complainant was still in possession of a knife. That information effectively ruled out a hand-to-hand engagement until such time as the officers could be assured he was no longer armed with a weapon. On this record, an ARWEN discharge made sense when the Complainant refused to peacefully surrender and began to close the distance with the officers. If it worked as designed, the use of the weapon would temporarily and sufficiently incapacitate the Complainant, allowing the officers a window of time within which they could safely approach and arrest the Complainant without the infliction of serious injury.
For the foregoing reasons, there is no basis for proceeding with criminal charges in this case.[5] The file is closed.

- 5) The use by WO #2 of his CEW was not the focus of the SIU investigation. That said, its initial use would appear reasonable for the same reasons justifying the SO’s ARWEN discharge. With respect to the multiple discharges that followed, there is a case to be made that they too were legally justified as a necessary precaution given the possibility that the Complainant remained in possession of a knife as the officers struggled to secure him in handcuffs on the ground.
