Operating rooms at Winnipeg's St. Boniface General Hospital are starting to reopen following last month's flood, with officials hoping to reopen all the rooms on Monday.

Fourteen operating rooms were flooded on Jan. 22 after the hospital's heating and cooling system malfunctioned and froze some pipes. The pipes burst, pouring water into a number of rooms.

The flooding forced the cancellation of hundreds of surgeries at St. Boniface and relocated some procedures to other hospitals.

Some emergency surgeries were performed at St. Boniface on Thursday morning, as three of its operating rooms were reopened, according to the Winnipeg Regional Health Authority.

Officials say all 14 operating rooms should reopen on Monday, but it will take about two months to catch up on delayed surgeries.

The health authority had hoped to reopen six operating theatres late last week, but air quality tests showed inconsistent readings.
