The Windsor-Essex Children's Aid Society has completed an investigation into an Ottawa Street daycare.

CAS launched the investigation after three children wandered away from La Garderie Les Petite Mains daycare on May 29.

Tina Gatt, manager of community outreach for the Windsor-Essex Children’s Aid Society, confirmed to CTV News the investigation is complete.

“In that process, we have reviewed their protocol around supervision to ensure the safety of those children,” says Gatt.

Gatt says it is up to their licence provider and ministry to deal with anything internally.
