Watchdog closes the book on 2008 allegation
Ottawa Police Association president Matthew Cox will not face criminal charges stemming from a sexual assault allegation dating back to 2008, after Ontario's Special Investigations Unit (SIU) reviewed the case and declined to recommend charges.
The SIU is the province's independent civilian oversight body responsible for investigating incidents involving police that result in serious injury, death, or allegations of sexual assault. Its involvement means the complaint against Cox was serious enough to warrant a formal, arm's-length review outside the Ottawa Police Service's own internal processes.
Who is Matthew Cox
Cox currently serves as president of the Ottawa Police Association, the union that represents front-line Ottawa police officers in labour negotiations, discipline matters, and workplace advocacy. As the public face of the association, his role carries significant weight in how Ottawa police officers are represented both internally and to the public — which is part of why an old allegation resurfacing, and the SIU's subsequent decision, is drawing attention across the city.
What the SIU decision means
An SIU recommendation against laying charges does not amount to a finding that an incident did not occur — it means investigators did not find sufficient grounds to pursue criminal charges based on the evidence available. For Ottawa residents who rely on the police service and its association to represent officers fairly and transparently, the outcome of SIU reviews involving police leadership remains a matter of public interest, particularly when the individual under review holds a prominent union position.
The case's resurfacing more than a decade and a half after the original allegation also highlights how historic complaints can still work their way through Ontario's civilian oversight system long after the fact, and how those processes intersect with someone's standing in an organization like the Ottawa Police Association.
What's next
With the SIU's review concluded and no charges recommended, the matter appears to be closed from a criminal standpoint. It remains to be seen whether the Ottawa Police Association or Ottawa Police Service will address the allegation through any internal or governance channels, given Cox's continued role representing the city's police officers.
Ottawa residents watching how police accountability plays out locally will likely keep an eye on how the association and police leadership respond, if at all, now that the SIU has weighed in.
