The Illusion of Oversight: Why the SIU Leadership Transition Must Be a Catalyst for Systemic Change

OPINION: As Director Joseph Martino's term ends, the SIU's dismal rate of charging officers suggests that replacing the leader without reforming the mandate is a failure of accountability.
The Special Investigations Unit (SIU) is currently standing at a crossroads. As first reported by CBC Toronto, the agency is actively seeking a new director as the term of current head Joseph Martino expires on December 31. For those who believe in civilian oversight for police in Ontario, this transition must be seen as a critical opportunity to question the agency's operational model.
Since 2019, Martino has steered the SIU, which investigates police incidents involving death, serious injury, shots fired at a person, or allegations of sexual assault. However, the data suggests a systemic reluctance to hold officers accountable. According to the SIU's annual report for 2024-25, cited by CBC Toronto, criminal charges were laid in only 17 cases involving 18 police officers—representing fewer than five per cent of all investigated cases.
This is a crisis of confidence. The current structure grants the director "the sole authority" to decide if charges are warranted, a concentration of power that, combined with a track record of near-universal exoneration, suggests a fundamental flaw. CBC Toronto has highlighted the human cost of this status quo, noting instances where Toronto police officers were cleared in the shooting death of a teenager and the serious injury of a cyclist during an arrest in May. While a London constable was recently charged with assault causing bodily harm, such cases remain the exception.
Further concerns regarding the agency's scope have emerged via CBC Investigates, which reported that the SIU no longer investigates the majority of off-duty sexual assault complaints. While the agency is still investigating new allegations—including two involving Ottawa police officers—the narrowing of its lens is a regression in accountability.
If the province simply replaces Joseph Martino with another director operating under the same mandate, nothing will change. The "sole authority" of the director is a bottleneck. Ontario deserves a police watchdog that does more than provide a veneer of oversight. With the job posting for the new director closing this Friday, the province should not be looking for a replacement to maintain the status quo, but a reformer willing to dismantle a culture of impunity.
