Three people were rushed to hospital early Sunday after being shot in the backyard of a townhouse in northwest Toronto, police say.
The incident happened shortly before 1 a.m. on San Antonio Way, near Steeles and Islington avenues.
Toronto police say two males were shot in the upper body and were in critical condition when they were taken to the trauma centre at Sunnybrook hospital.
A third male was taken to Etobicoke General Hospital and later transferred to Sunnybrook with a leg wound.
Sgt. Dion Monahar told CBC News that the victims were "approached by a number of suspects" who opened fire.
Monahar said "a significant number" of shots were fired.
Those suspects were last seen heading northbound, away from the scene.
Not much is known about why the victims were shot.
"I don't have a definitive motive for this shooting at this time," Monahar said.
The shooting happened on a Toronto Community Housing property. Monahar said that police would be reviewing all available surveillance video.
"There is extensive closed-circuit television video available to us," he said.
Police have not released the ages or names of the victims.
They're looking for a car that was driven from the scene after the shooting.
