Police said the call came in just before 7 p.m. and the three victims were found with gunshot wounds just off the highway at a gas station near Weston Road and Finch Avenue West.
“The victim’s were travelling southbound on the 400, just south of Steeles when another vehicle opened fire on them. The victim was able to make it to this location,” Duty Inspector Stacey Davis told reporters Saturday night.
When officers arrived, they found one man with life-threatening injuries and two other men in their 20s with serious injuries, all suffering from gunshot wounds.
One man later died in hospital and the two other men are expected to survive, police said.
In an update Sunday afternoon, police said the deceased man has been identified as 28-year-old Terrence Agtual from Toronto. He was the passenger in the vehicle that was struck by bullets.
“A suspect vehicle approached on the driver’s side and opened fire … striking the vehicle numerous times,” Det. Sgt. Brandon Price said. “This appears to be a targeted situation … the vehicle itself at least was targeted for this attack.”
Price said the other two men were released from hospital shortly after the shooting occurred on Saturday night. Agtual died Sunday morning and had been shot in the head, Price said.
Price said that the victim had been involved with police before and has a criminal record.
Davis said earlier that investigators found shell casings along the highway and police believe that the shooting took place on the highway.
Police said they do not have any suspect descriptions available to release.
The highway was closed for the investigation, but has since re-opened.
Investigators are asking anyone with dashcam video who were travelling along Highway 400 in that area between 6:45 p.m. to 7 p.m. to call police.
