Police are investigating allegations of negligence at an east-end Toronto day-care centre that resulted in a child being injured.

Allegations from investigators say that a child at the Happy Child centre suffered "a number of injuries." Police also say that the centre, located at 173 Withrow Avenue, did not have a license.

Investigators added that the centre allegedly had "several infractions" that would have prevented the facility from being licensed.

On Wednesday, the Ministry of Community and Social Services ordered the private-home day-care centre closed.

For parents arriving at the private home Thursday morning, the closure came as a shock. Many said it was a well-run facility.

"We certainly wouldn't want to know of another child that's suffered," a parent known only as Suzanne told CTV's John Musselman.

"And I find that hard to believe so we called Children's Aid to see what had happened because, as parents of a child in this day care, we want to know."

Other parents said the day care's owner, who was only identified as Gloria, does a terrific job with their children.

"All I can tell you is that our child care was excellent," one father said.

Police have not elaborated on the child's injuries or how they occurred. Investigators only say they are looking into allegations of negligence related to the injuries.

Police are being joined in their investigation by representatives from Community and Social Services and Toronto Children's Aid.

Investigators are making it clear that this is not a case of child abuse. They merely reiterate that a child sustained substantial injuries which required medical treatment.

"We have injuries to a child that we have to investigate," Det. Glen Gray said Thursday.

"How the injuries took place, why they took place, why they were allowed to continue, all of those things is hopefully what our investigation will reveal."

Investigators ask anyone with information about the day-care centre to call police at (416) 808-5505 or Crime Stoppers anonymously at (416) 222-TIPS (8477).
