On March 12, 2026, students and staff at Guelph Collegiate Vocational Institute in Guelph, Ontario, were placed under a mandatory lockdown after the school received a threat. The Guelph Police Service arrived at the campus on Paisley Street shortly after 1:00 p.m. to ensure the safety of everyone inside.
Police officers contained the area and conducted an investigation alongside the Upper Grand District School Board. This response was taken to protect the school community while authorities worked to determine if the threat was real.
The lockdown was lifted at 2:15 p.m. after investigators determined the threat was unfounded. No injuries were reported, and the school was cleared to resume its regular activities.
The Guelph Police Service is still looking for the source of the threat. They are asking anyone with information to contact Detective Constable Cecilia Hudecki at 519-824-1212, extension 7215.
