Earlier Tuesday, it looked like they might go ahead but later in the day the hospital issued a news release announcing the decision had been reversed.
The Saskatoon Health Region had said crews were able to reroute power to the medical systems affected, but the later release said there was still too much uncertainty about the restoration of water pumps.
Power flow to some areas was cut off after a piece of equipment failed during a planned shutdown to do electrical upgrades.
Medical suction and air flow in the building were affected, particularly in operating rooms.
Patients whose surgeries were postponed will be contacted by the hospital with new dates.
