Toronto police are investigating a series of bomb threats that occurred Tuesday morning at post-secondary campuses across the city.

Officials have confirmed that Ryerson University, OCAD University, George Brown College and Humber College are all involved, impacting 10 campuses around the Toronto area.

Ryerson University, in the city’s downtown core, informed the public that the police investigation at the Chang School concluded, with the building officially reopened.

George Brown College has confirmed that the school received a “threatening email,” which prompted the police activity.

Humber College also confirmed that a threat was received but Toronto police did not instruct any of the campuses to evacuate.

OCAD University will remain closed for the rest of the day, due to the investigation but will reopen Wednesday morning. Police have concluded their search at the school and have cleared the campus.

No injuries have been reported at this time and anyone with information is being asked to contact police.
