Two colleges were locked down late last week in response to safety concerns on campus. Police were called to Collège Lionel-Groulx on Friday to investigate a report of a “potential active shooter,” according to CTV News, and students and staff locked themselves inside during the investigation. The lockdown was lifted after authorities confirmed that “no criminal act” had been committed, and the college notified students of available mental health supports. City News notes that this is the third lockdown at a Quebec college in a week. Sheridan College’s Oakville campus and residences were shut down on Saturday and all events – including the Fall Open House – cancelled for the day after the college was notified by Halton Police of a potential security concern in the area. The Star reports that Halton Police later confirmed there was no immediate threat to safety, and the campus was reopened at 4:30 PM.
