Shortly before 2 p.m., Peel Regional Police received a call about a stabbing outside the Erin Mills Town Centre, near Erin Mills Parkway and Eglinton Avenue West.
Two male victims were rushed to a trauma center in critical condition, Peel Regional Paramedics said.  Police did not give their exact ages, but described them as young.
One of them has been upgraded to stable, police told CP24, while the other remains in critical condition.  The victim is reportedly an up-and-coming rapper, one of his friends told CP24 Thursday night.
Witnesses told police that a suspect — described as a South Asian male between 15 and 17 years old wearing a black T-shirt and gray Nike sweatshirt — fled on foot.  Police said later Thursday afternoon that they had a suspect in custody.
“We don’t know the exact circumstances surrounding what happened, but we don’t believe there is a risk to public safety at this time,” said Const.  Sarah Patten told CP24 on the scene.
He said it was not yet clear whether the victims and the suspect knew each other or what the motive for the stabbing might have been.
“It is my understanding that the incident started on school property and then came to this parking lot,” Patten said.
Several items of clothing and what appeared to be a backpack appeared to be between two vehicles at the scene Thursday as police searched the area.
Police are asking anyone with information to come forward to investigators.
“We’re asking anyone with any information to contact the 11th Precinct Bureau of Criminal Investigation, and if you have any surveillance or dash cam video, please check it out,” Patten said.
