A shelter-in-place order issued as police responded to a dangerous weapons call at a University of Toronto dormitory in Mississauga has been partially lifted.

The school announced the update in an alert early Tuesday, adding that the lockdown remains in effect for McLuhan Court residence.

The alert says the situation has been contained to a single residential unit and that there have been no reports of physical injuries.

Peel Regional Police have said the immediate area was evacuated late Monday and urged the public to stay away.

On social media, the force described the matter as a dangerous weapons call, though further details have not yet been shared.

The university says on its website that McLuhan Court provides beds for hundreds of first-year students.
