SIU Investigating Police-Involved Shooting in Nepean

Case Number: 23-OFI-071   

Mississauga, ON (5 March, 2023) ---
The province’s Special Investigations Unit is investigating the circumstances surrounding a police-involved shooting that occurred last night in Nepean.

Preliminary information suggests the following:
  • At approximately 9:40 p.m. on March 4, 2023, a person contacted the Ottawa Police Service to report concern for another individual, and that the individual was in possession of firearms.
  • Officers attended a townhouse complex on Garden Glen Private and attempted to make contact with a 28-year-old man by phone and by knocking at the door. This was to no avail.
  • Some time later, there was an exchange of gunfire between the man and police. Three officers discharged their firearms and the man was struck.
  • The man retreated into the home, but he eventually surrendered.
  • He was transported to hospital for treatment of serious injuries. 

Three investigators and two forensic investigators have been assigned to the case. At this time, three subject officials and six witness officials have been designated.

The SIU is urging anyone who may have information about this investigation, including video or photos, to contact the lead investigator at 1-800-787-8529 or online at:
