Operations at Credit Valley Hospital in Mississauga are back to normal after a threat was made Tuesday night, Peel regional police say.

Officers responded to the scene shortly after 6 p.m. to investigate a call to the hospital's switchboard.

A tactical team conducted a search of the property but did not locate a suspicious package.

Officers determined that there is no danger to the hospital, its patients or staff.

Traffic was initially restricted for vehicles and buses in the area but ambulances were still able transport patients who required emergency treatment.

Normal operations at the hospital resumed around 9 p.m.

All restrictions that were in place have been lifted and all roads have since been re-opened, police say.

Police have no information on a suspect but are continuing to investigate the incident.
