SIU Director’s Report - Case # 23-OVI-403


This page contains graphic content that can shock, offend and upset.

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 serious injury of a 22-year-old man (the “Complainant”).

Physical Evidence

SIU forensic investigators arrived on scene at 4:21 p.m., October 2, 2023.
Several involved vehicles were located on the southwest corner of the intersection on the grass shoulder, across the sidewalk and against a chain-link fence. This area was cordoned off with yellow police scene tape.

Vehicle one was a Mercedes Benz G550. Vehicles two, three and four were unmarked PRP TRU vehicles. Vehicle five was a Toyota and vehicle six was an unattended parked Volvo. The Toyota and Volvo were parked in a parking lot.

A review of the scene indicated that the stolen Mercedes G wagon came into head-on contact with the SO’s PRP TRU vehicle in the intersection. Two PRP TRU vehicles followed the stolen Mercedes G wagon into the southwest corner of the intersection over the curb and into a chain-link fence, where the Mercedes struck the parked Toyota once the fence gave way. The Toyota was then pushed into the Volvo parked next to it.

Video/Audio/Photographic Evidence [fn]3[/fn]

Video Footage - Civilian #1

On October 5, 2023, the SIU obtained video footage from Civilian #1.

Starting at about 10:09 a.m., the Mercedes G wagon approached the intersection from the west on Williamsport Drive. The SO’s vehicle entered the intersection from the north and collided with the Mercedes G wagon in the intersection. The impact of the collision caused the Mercedes G wagon’s left side wheels to become elevated off the roadway. Another PRP TRU vehicle then struck the stolen Mercedes G wagon on the driver’s side while it was on two passenger wheels, causing it to come down onto four wheels and crash into a chain-link fence. A third PRP TRU vehicle entered the intersection from the north and pinned the stolen vehicle from behind.

Additional PRP vehicles immediately stopped and surrounded the Mercedes G wagon. PRP TRU officers exited their respective vehicles and pointed their firearms at the occupants inside the Mercedes.
Starting at about 10:15 a.m., the first marked PRP cruiser arrived from the south and stopped in the intersection. It had its emergency roof lights on. A person, in handcuffs behind his back, was walked to this police vehicle.
At 10:18 a.m., a second marked PRP vehicle arrived at the intersection with its emergency lighting activated.

PRP Communications Recordings and Computer-aided Dispatch (CAD) Report

On October 2, 2023, at 9:43 a.m., PRP dispatch asked units to attend at a carjacking in the area of 175 Fletcher’s Creek Boulevard in Brampton. Several PRP units acknowledged. Information was provided indicating that a black Range Rover had attended the address with four men inside. One man had a black handgun and pointed it at a woman. He demanded the keys for her Mercedes G wagon. She gave the man her keys, and the suspects drove off onto Fletcher’s Creek Boulevard. The plate number of the stolen Mercedes G wagon was provided.

At 10:14 a.m., a Criminal Investigation Branch officer broadcast that two men were in custody, and the original Range Rover had not been located. Patrol officers and a sergeant were requested to attend the scene at Havenwood Drive and Williamsport Drive.

Emergency Medical Services was requested at 10:20 a.m.

Incident Narrative

The evidence collected by the SIU, including interviews with the Complainant, the SO and other police and civilian eyewitnesses, as well as video footage that captured the incident in parts, gives rise to the following scenario.

In the morning of October 2, 2023, officers with the PRP TRU were mobilized to locate and arrest the perpetrators of a carjacking earlier that day. A woman had contacted police to report that a male had approached her in the parking lot of 175 Fletcher’s Creek Boulevard, Brampton, pointed a handgun at her and demanded her car key. She surrendered the key and the male took off with others in her Mercedes G wagon. With the help of the police, the caller was able to provide information regarding the vehicle’s location and direction of travel via an application on her phone.

The male was CW #1. He would come to occupy the front passenger seat in the Mercedes. The driver of the vehicle was the Complainant.

Unmarked police vehicles surreptitiously tracked the Mercedes as it travelled into Mississauga. The SO was operating a vehicle travelling south on Havenwood Drive when he spotted the Mercedes stopped facing east at the roadway’s intersection with Williamsport Drive. Behind the officer were two other TRU vehicles, one operated by WO #1, with WO #3 as his passenger, and the other driven by WO #2. The SO travelled into the intersection to block the Mercedes’ path of travel. His vehicle and the Mercedes collided as the latter travelled into the intersection. The impact lifted the Mercedes such that it was briefly riding on its passenger side wheels while turning right onto southbound Havenwood Drive. Moments later, WO #1 drove up alongside the Mercedes and struck its driver’s side, forcing it onto the sidewalk and into a chain-link fence that bordered the property on the southwest corner of the intersection. WO #2 followed and struck the rear of the Mercedes, further driving it into the fence.

The Complainant, who was not wearing a seatbelt, was thrown into the rear passenger compartment by the impacts, suffering a fractured right clavicle in the process. CW #1 remained in the front passenger seat and did not sustain any serious injuries.

Officers rushing to the vehicle following the impacts deployed flash-bangs into the Mercedes, discharged CEWs at the Complainant, and removed CW #1 and the Complainant at gunpoint, after which they were taken into custody.

The Complainant was transported to hospital from the scene and diagnosed with his injury.

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 seriously injured in a motor vehicle collision in Mississauga on October 2, 2023. As his vehicle had been struck by PRP cruisers, the SIU was notified of the incident and initiated an investigation. The SO was identified as 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 Complainant’s injury.

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 911 call made by the owner of the Mercedes would have given the SO and his colleagues reason to believe that the occupants of the Mercedes had just stolen the vehicle while brandishing a gun. In the circumstances, the officers were engaged in the execution of their lawful duties when they sought to apprehend CW #1 and the Complainant at the intersection of Williamsport Drive and Havenwood Drive.

With respect to the force brought to bear by the officers in aid of the arrests, the evidence falls short of any reasonable suggestion it was unlawful. There is conflict in the evidence as to whether the SO intentionally rammed his vehicle into the Mercedes, or his vehicle was stationary in front of the Mercedes when it was rammed by the Complainant. Assuming the former – the potentially more incriminating of the accounts – it would not appear the tactic was so clearly out of bounds as to amount to excessive force. Knowing what he did of the apparent gunplay [fn]4[/fn] by the occupants of the Mercedes, it was critical in the interests of public safety that CW #1 and the Complainant were arrested as soon as possible. And here was an opportunity, an intersection with a small to moderate amount of traffic, to do so with the use of their vehicles. I accept that the use of a vehicle to intentionally contact another vehicle is inherently dangerous, but there were a number of mitigating factors at play. First, TRU officers were specially trained in the tactic. And, second, the impact occurred at relatively slow speed. All in all, I am unable to reasonably conclude on this record that driving the vehicle into the Mercedes, if that is what the SO did, amounted to a disproportionate response to the exigencies of the situation. Similarly, for essentially the same reasons, I am not reasonably satisfied that WO #1 or WO #2 acted with excess when they also struck the Mercedes. [fn]5[/fn]

For the foregoing reasons, there is no basis for proceeding with criminal charges in this case. The file is closed.
