Toronto police say a youth has critical injuries after being stabbed near a school on Thursday afternoon prompting a lockdown. 

Emergency crews were called to the Oakwood Avenue and St. Clair Avenue West area just after 2:30 p.m. on Friday.

A 17-year-old Toronto student has been charged after police say they foiled a potential attack at a local high school to coincide with the anniversary of the massacre at École Polytechnique in Montreal.
