All ambulances had to be redirected from the St. Catharines hospital after a patient pulled a fire sprinkler line in the Emergency Department.
This caused flooding in the back area of Pod A early yesterday morning.
Niagara Health says no one was hurt but 17 patients had to be evacuated to either the medical, surgical or critical care units based on their condition.
The St. Catharines Fire Department was called in to help but everything is now business as usual.
