Ottawa residents who file a sexual assault complaint against an off-duty police officer may find their case reviewed differently than it would have been just a few years ago. That's the picture emerging from new CBC News data showing a steady decline in the number of police-involved sexual assault complaints investigated by Ontario's Special Investigations Unit (SIU) since 2021.
What the SIU Does
The SIU is the province's independent police watchdog, responsible for investigating cases involving police that result in death, serious injury, or allegations of sexual assault — including incidents involving officers who are off duty. Because Ottawa police officers fall under the SIU's jurisdiction just like every other municipal and provincial force in Ontario, any changes to how the watchdog handles these complaints ripple directly into how cases involving Ottawa officers are handled.
According to the CBC News analysis, the number of complaints the SIU has actually taken on for full investigation has dropped noticeably since 2021. Researchers who reviewed the data say changes to the SIU's investigative mandate — specifically, tighter interpretations of when the watchdog is required to step in on off-duty allegations — appear to be behind much of that decline.
Why It Matters for Ottawa
Ottawa is home to one of the largest municipal police services in the province, and advocates who work with survivors say the SIU's shrinking role in off-duty cases could have an outsized effect locally. When the SIU declines to investigate, complaints can be redirected back to individual police services for internal review — a process advocates argue can discourage survivors from reporting altogether, given the inherent difficulty of an officer's own employer investigating a colleague.
Survivor advocacy groups that operate in the Ottawa area told CBC News they're already worried the trend will translate into fewer people feeling safe enough to come forward, particularly in cases involving officers they may have to continue encountering in their community.
The Bigger Picture
The SIU's mandate has been the subject of ongoing debate in Ontario for years, with police accountability advocates repeatedly calling for clearer, broader criteria for when the watchdog must open an investigation involving an officer, whether on or off duty. The recent data suggests that debate isn't settled — and that the practical effect of narrower rules is already showing up in the numbers.
For Ottawa residents, the takeaway is straightforward: complaints against local officers are subject to the same provincial rules shaping this decline, meaning the same forces affecting reporting rates elsewhere in Ontario are very much in play here too.
