Toronto police shot and killed a Windsor man in the city's north end on Wednesday morning in a domestic dispute that left a woman stabbed in the neck.

The Special Investigations Unit (SIU) said neither the man nor his wife were residents of the building at 3460 Keele St., north of Sheppard Avenue, where the incident took place before 9 a.m.

Witnesses reported hearing officers yelling to the 37-year-old man to drop a knife before he was shot.

SIU investigator Carm Piro said the man, whose name has not been released, was hit with a single bullet. Piro, however, did not comment on where the man was struck.

The man was taken to Sunnybrook Hospital, where he was pronounced dead in the emergency room.

The man's wife was stabbed in the neck and taken to hospital. Her injury was considered non-life threatening.

The couple was visiting relatives in unit 118 with their small child before the dispute erupted. Other children were also inside the apartment.

The SIU has designated one Toronto officer and named seven others as witnesses.

The agency spoke to residents but is still investigating.

Additional information is not known at this time.

The SIU is a civilian agency that investigates circumstances involving police and civilians that have resulted in serious injury, sexual assault or death.

Anyone with information to contact the unit at 1-800-787-8529 or Crime Stoppers anonymously at 416-222-TIPS (8477).
