Mississauga, ON (24 November, 2023) ---
In April 2023, in the interests of avoiding any potential or perceived conflict of interest, the Nova Scotia Serious Incident Response Team (SiRT) asked Ontario’s Special Investigations Unit (SIU) to review information considered by the Joint Federal/Provincial Commission into the April 2020 Nova Scotia Mass Casualty, with respect to shots fired by two RCMP officers at the Onslow Fire Hall on April 19, 2020. 

The objective was to assess whether there was any new information that had been reviewed by the Commission that had not been considered in SiRT’s investigation of the shooting.  The review concluded that new information was considered. As a result, the SIU has agreed to review any new information to determine if it would impact the SiRT decision, subject to any limitations imposed by law. 

The SIU will begin its independent review in the near future, with the goal of completion as soon as reasonably possible. 

The Directors of the SIU and the SiRT understand that the issues examined by the Mass Casualty Commission are difficult and that this review may cause psychological distress. If you or someone you know needs support, you can contact the services listed below:

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
