The outage also impacted all buildings at the Toronto Metropolitan University and the Eaton Centre, but as per the , power has been restored. However the Ontario Ombudsman’s office close by, near Bay and Albert streets, closed for the day due to the outage.

In a statement, the University Health Network (UHN) said that Toronto General Hospital is experiencing a power outage.

“Backup generators are functioning and there is no widespread impact to patient care,” they said. “Care teams will reach out directly to any patients who may experience a delay.”
