Police survey a crime scene following a shooting in Scarborough, a suburb of east Toronto, on Tuesday morning.

An infant was also wounded in the shooting, he told CBC, although the child's injuries were not life threatening.

"I've been a cop for 35 years, this is the worst incidence of gun violence in my memory anywhere in North America," Blair said.

A report in the Globe and Mail said police had a person in custody, and that the shooting appeared to be a dispute.

"It's got to stop, there's no need for it," he said.
