Three children suffered minor injuries after a portion of a ceiling fell on them at a Roncesvalles daycare centre.
Police were called to the Dundas Street West and Boustead Avenue around 12 p.m. Monday afternoon.
Ceiling tiles and plaster fell on the children while they were napping.
Crews evacuated 21 children and nine staff members from the building and the parents of the injured children were contacted.
One child was taken to hospital with minor injuries, while the other two were treated on the scene.
The building inspector was notified as Toronto Fire was concerned about the structure of building.
Toronto Fire Capt. Adrian Ratushniak told CityNews the engineer that assessed the scene suggested that the roof collapse was likely due to aging construction.
“They’ve determined that the ceiling had collapsed probably due to the age and construction — the old lath and plaster construction along with acoustic tiles on top,” he said
He added that the building itself was determined to be structurally sound.
