Four men, including one with non-life threatening but critical injuries, were rushed to Toronto trauma centres after a shooting in the city's northwest on Monday afternoon, police say.
The three other men injured in the shooting suffered serious but non-life threatening injuries.
Toronto police said gunfire erupted at a business in the Tangiers Road and Finch Avenue West area. Officers were called to the area at 1:02 p.m.
Insp. Ishmail Musah, spokesperson for the Toronto Police Service, said they found four victims with gunshot wounds.
"Officers immediately began first aid and continued first aid until paramedics arrived and transported the victims to hospital," Musah told reporters near the crime scene.
Musah said police have not yet determined what what led to the shooting.
"We believe that a vehicle was in the area and went into the address behind me, to an industrial area, and fired off rounds at people waiting at this business. We don't have an idea in terms of motive at this point but that will be found out as part of the investigation," he said.
A blue car was seen leaving the area shortly after the shooting, but police haven't released a description of a suspect or suspect vehicle.
Investigators have shut down roads in the area.
Toronto Police are asking anyone with video or information to call 31 Division.
