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.
Authorities have advised the public to avoid the scene at Progress Ave and Corporate Drive.
Armed officers, ambulances and fire engines remain in the area as police continue the search for the suspect.
Toronto paramedics told Canada's CP24 Media it was a "dynamic situation", adding that injuries ranged from minor to critical.
Olivia Chow, mayor of Toronto, said: "I am deeply troubled to hear reports of a shooting at a pub in Scarborough.
"I have spoken to (Toronto Police Chief Myron) Demkiw and he has assured me all necessary resources have been deployed. This is an early and ongoing investigation - police will provide further details.
"My thoughts are with the victims and their families."
