Due to Lack of Cooperation from Man, SIU Discontinues Tillsonburg Investigation

Case Number: 25-OCI-454   

Mississauga, ON (2 February, 2026) ---
The Deputy Director of the Special Investigations Unit, Stacey O’Brien, has terminated an investigation into the arrest of a 42-year-old man in November in Tillsonburg.

In the morning of November 12, 2025, the man was arrested at his residence during the execution of a search warrant by the Halton Regional Police Service Tactical Unit. During the arrest a struggle ensued. A conducted energy weapon was deployed, followed by the use of empty-hand control techniques to gain control of the man. He was subsequently transported to hospital and reportedly diagnosed with fractures to his nose.

Based on the SIU’s preliminary inquiries, Deputy Director O’Brien was satisfied that the investigation should be discontinued. The man declined to provide an interview to SIU investigators and he did not consent to the release of his medical records. In the absence of a statement, and no evidence of serious injury being identified within the mandate of the SIU, the unit was without jurisdiction to investigate the incident. The file has been closed.

The SIU is an independent government agency that investigates the conduct of officials (municipal, regional and provincial police officers, police officers with the Nishnawbe Aski Police Service, special constables with the Niagara Parks Commission and peace officers with the Legislative Protective Service) that may have resulted in death, serious injury, sexual assault and/or the discharge of a firearm at a person. All investigations are conducted by SIU investigators who are civilians. Under the Special Investigations Unit Act, the Director of the SIU must

  • consider whether the official has committed a criminal offence in connection with the incident under investigation
  • depending on the evidence, cause a criminal charge to be laid against the official where grounds exist for doing so, or close the file without any charges being laid
  • publicly report the results of its investigations
