The Special Investigations Unit says the man was shot multiple times and pronounced dead at the scene.
Peel Regional Police said Friday night that one officer was shot and the other was stabbed, and described the injuries as serious. The SIU says the injuries to the officers and the civilian are not life-life threatening.
The incident happened after police responded to a call (on Queen Frederica Drive near Dundas and Dixie) and "interacted" with a man.
The SIU has assigned five investigators and three forensic investigators to probe the circumstances of the incident. Three subject officers and seven witness officers have been designated.
The agency wants to hear from anyone with information about the incident.
The SIU is an arm’s length agency that investigates reports involving police where there has been death, serious injury or allegations of sexual assault.
