A total of 102 youngsters were relocated to other parts of the Health Sciences Centre late Tuesday when a fire broke out in part of the hospital that is under construction.
Some of the children were in the neonatal and pediatric intensive care units, but no one was hurt.
A news release from the Winnipeg Regional Health Authority says the kids were returned after housekeeping staff cleaned the areas.
One firefighter suffered minor injuries battling the blaze.
The cause of the fire is not yet known.
