TORONTO (AP) — Canadian Prime Minister Justin Trudeau says it’s not an isolated incident that over 200 children were found buried at a former Indigenous residential school. Trudeau’s comments come as Indigenous leaders are calling for an examination of every former residential school site — institutions that held children taken from families across the nation. Chief Rosanne Casimir of the Tk’emlups te Secwepemc First Nation in British Columbia says the remains of 215 children were confirmed this month at the Kamloops Indian Residential School. From the 19th century until the 1970s, more than 150,000 First Nations children were required to attend state-funded Christian schools.
