At least 12 people have been injured following a shooting in Toronto, according to police.
Four victims sustained non-life-threatening injuries, while the condition of the remaining victims is not yet known, officers said.
Toronto Police described the three suspects as "wearing a black balaclava" and seen "fleeing in [a] silver car". All suspects remains at large.
Officers responded to reports of gunfire at the Piper Arms pub in Scarborough, a district in Toronto, at approximately 10.39pm local time.
