The teenage victim, identified as Kareem Deerr, was found with stab wounds in the upper torso after a fight broke out at the station with two groups of men, all younger than 18, investigators said.
Deerr was rushed to the hospital and succumbed to his injuries there.
“Help us bury our little brother,” reads a GoFundMe page set up by Deerr’s family.
“I’m sure he is up there looking down at everyone who helped and he is smiling,” a family member wrote on the page. “This means so much to my family.”
About 50 to 100 people were in the area during the fatal altercation, police said.
Desmond Lincoln Williams, 18, of Toronto has been charged with second-degree murder.
A 14-year-old has also been arrested and charged with manslaughter. The identity of the teen is protected under the Youth Criminal Justice Act. Both are scheduled to appear in court on Friday, Sept. 30.
