SIU Charges Sault Ste. Marie Police Officer for Sexual Assault Offences

Case Number: 22-OSA-322   23-OSA-028   

Mississauga, ON (5 December, 2023) ---
The Director of the Special Investigations Unit, Joseph Martino, has reasonable grounds to believe a Sault Ste. Marie Police Service officer committed criminal offences.

The SIU investigations concluded that there was sufficient evidence to proceed with sexual assault charges against the officer in relation to two women arising from incidents in December 2022. 

As a result of the SIU investigation, Sgt Marc Dubie is facing charges of two counts of sexual assault, contrary to section 271 of the Criminal Code.

Sgt Dubie is required to appear before the Ontario Court of Justice at 426 Queen Street E. in Sault Ste. Marie on January 8, 2024, at 9 a.m.

As the matter is before the courts, and in consideration of the fair trial interests of the accused, the SIU will not provide further comment on the investigation.  

The SIU is an independent government agency that investigates the conduct of officials (police officers as well as 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
