The province’s Special Investigations Unit is investigating the circumstances surrounding the discharge of a police firearm last night in Mississauga.

Preliminary information suggests the following:

  • When two men approached a vehicle of interest, the officers conducted a takedown.
  • One man was arrested. 
  • The second man became involved in an interaction with police, and one officer discharged his firearm. The man fled the scene and is yet to be located.
