Two men died after shooting in a Vaughan banking room and a restaurant early on Saturday, says York Regional Police.
Police believe there could be other victims.
Officers were called the Dream Palace Banquet Hall and Restaurant, 8131 Keele St., near Rivermede Road, at 4:16 a.m. Several people called 911 about the sound of guns.
"After arriving, it was a completely chaotic scene," Staff Sgt. David Mitchell, an official inspector for York Regional Police, said Saturday.
Officers found two men suffering from fire injuries.
One, found inside the restaurant, was pronounced dead at the scene.
The other, found outside, was operated to Toronto traumatic center, where he died of his wounds. He was shot in the legs, Mitchell said.
No names or ages have been released.
Police is not sure what was going on to shoot
"Just what happened the events we do not know. The research is in his childhood," he said.
Police try to identify the bodies, Mitchell said. Next of them have not been notified yet.
There were people at the restaurant when the shooting took place, he added.
"I know that a lot of people have caught hold of leaving this restaurant when our officers arrived," he said.
"Whenever you have a bow in a crowd, there is a possibility that other people hurt. If they fled the scene and they hurt, we do not know what is still."
Restaurant behind a police tape
Police did not publish any suspicious information, but officers knocked down the restaurant and tried to get a security camera.
Officers did not recover a gun.
Homicide detectives and legal teams are on stage.
