TORONTO - Officials from the Toronto Caribbean Carnival say they are shocked and saddened by the fatal shooting that took place along the festival's parade route on Saturday.

A 30-year-old man from Scarborough was killed and two other people were injured in the incident, which occurred about an hour after the annual parade had ended.

Ontario's police watchdog has been called in to probe how Toronto police handled the case.

The Special Investigations Unit is automatically called in when police involvement in a situation results in death or serious injury.

An SIU statement said three people were taken to hospital with gunshot wounds: the man who later died, a 21-year-old woman from Pickering who underwent surgery and remains in critical, but stable condition, and an 18-year-old man from Scarborough who suffered a minor injury.

The festival's CEO Denise Herrera Jackson said in a statement on the carnival's website that organizers are deeply saddened by the loss of life.

"Our festival is about love and community, and to have this happen so close to our event is devastating," Jackson said in the statement.

"We work so hard to make our event safe and family friendly, it is unthinkable that such a thing could happen."

The SIU says it has assigned nine investigators to the case.

Toronto's Caribbean Carnival, formerly known as Caribana, is touted as the largest festival of Caribbean culture in North America.

Tens of thousands of people had lined the parade route Saturday afternoon.
