The Jewish General Hospital is once again fully operational three days after a power surge knocked out computer systems.
On Friday the power failures shut down several computer systems, including in the emergency room and test centre, although other systems were not affected.
Ambulances were diverted to other hospitals on Friday and over the weekend while the computer problems were repaired.
After three days of work staff members were able to bring everything back online on Monday morning.
The hospital stresses that at no point during the three-day failure were any patients in danger.
