KAMLOOPS, British Colombia (AP) The remains of 215 children, some as young as 3 years old, have been found buried on the site of what was once Canadas largest Indigenous residential school one of the institutions that held children taken from families across the nation.

Chief Rosanne Casimir of the Tkemlups te Secwpemc First Nation said in a news release that the remains were confirmed last weekend with the help of ground-penetrating radar.

More bodies may be found because there are more areas to search on the school grounds, Casimir said Friday.

In an earlier release, she called the discovery an unthinkable loss that was spoken about but never documented at the Kamloops Indian Residential School. It was the once the site of Canadas largest residential school.
