One person has died and two others were injured Saturday, when gunfire broke out along the Caribbean Carnival  parade route in Toronto, police said.

Police also confirmed that the Special Investigations Unit has been notified and is taking over the investigation. The SIU, an arm's-length agency, is called in following incidents in which police are somehow involved in a serious injury or death.

EMS officials said two people — one male, one female — suffered multiple gunshot wounds, while the third victim was injured in the eye during the shooting on the Caribbean festival parade route outside Ontario Place.

The third victim is considered to be a bystander whose eyebrow was grazed by a stray bullet, paramedics said. The other two victims were rushed to hospital with life-threatening injuries.

The shooting reportedly occurred around 7:30 p.m., roughly an hour after the parade ended.

Toronto's Caribbean Carnival, known in previous years as Caribana, draws more than a million spectators to the streets every year.

Violence overshadows festivities

CBC's Ivy Cuervo, reporting from the scene, said the outbreak of violence on Saturday overshadowed the festive atmosphere.

Many bystanders were still milling about the area when the shots rang out and some believed the sound to be firecrackers, until they saw others running.

"There were lots of people in the area when it actually occurred," Cuervo said. "There's a sense of disappointment at this point from some of the people I spoke to. One lady did tell me she'll still come next year [to the carnival], but it's just left a bitter taste for many people."
