A Halton Regional Police sergeant has been charged following an investigation into a pursuit involving a stolen Hummer that ended in a serious collision in Mississauga in March 2025.
Sgt. David Joseph faces one charge of dangerous operation of a conveyance causing bodily harm, according to Ontario’s Special Investigations Unit (SIU). Director Joseph Martino determined there were reasonable grounds to believe the officer had committed a criminal offence.
The incident began on March 12, 2025, as officers investigated the theft of a Kia Sedona from a residence in Oakville involving a stolen GMC Hummer. The drivers of both vehicles fled, prompting police to attempt to stop them.
According to the SIU, a pursuit led by Sgt. Joseph ended near Winston Churchill Boulevard and Lakeshore Road East, where the Hummer collided with a tractor-trailer.
The 26-year-old Hummer driver was arrested and taken to hospital with serious injuries.
The SIU declined to provide further details, citing the ongoing court proceedings and the accused officer’s right to a fair trial.
Sgt. Joseph is scheduled to appear in Milton court on Nov. 23.
