The man fatally shot by Toronto police officers Friday night in North York was an Ottawa resident with a history of mental illness.

The Special Investigations Unit, Ontario's police watchdog, says officers shot the 30-year-old man during a confrontation in front of a house on Bayview Avenue — south of Steeles Avenue East — around 10 p.m. last night.

He was rushed to Sunnybrook Hospital where he was pronounced dead.

Police in Toronto and Ottawa would not identify the victim, but his uncle told CBC News it was Devon LaFleur, whom Ottawa officers reported as missing and possibly armed with a gun on Friday.

At the time, police warned people not to approach LaFleur. His family told officers they were concerned for his safety.

On Saturday, Ottawa police issued a short statement saying LaFleur had been found, offering no further details.

According to his family, LaFleur suffered from bipolar disorder.

SIU spokesman Jason Gennaro told reporters that three officers shot at the man. Another nine who were on the scene will also be part of the investigation.

"If witnesses saw anything they should contact the lead investigator at the SIU," Gennaro said. ​

The SIU investigates deaths, serious injuries or alleged sexual assault involving the police.

CBC News has reached out to the SIU for further comment.
