More than 3,000 indigenous children and youth died in residential schools - many of them buried in unmarked graves - and those who had the power to prevent these deaths did little to stop it. The heartbreaking details of those deaths are contained in the final report of the Truth and Reconciliation Commission (TRC) released Tuesday, which details the dark history and unsettling legacy of Canadian residential schools that saw 150,000 First Nations, Mtis and Inuit children come through their doors. "Many students who went to residential school never returned," says the final report. "They died at rates that were far higher than those experienced by the general school-aged population. Their parents were often uninformed. No one took care to count how many died or to record where they were buried." says the final report, [which] includes a volume titled "Missing Children and Unmarked Burials" detailing the circumstances, when known, of the 3,201 students deaths between 1867 and 2000 it was able to record. "Both the regulatory regime in which the schools operated and the level of compliance with that regime were inadequate to the task of protecting the health and safety of the students. "Government, church, and school officials were well aware of these failures and their impact on student health. If the question is, 'Who knew what when?' the clear answer is, 'Everyone in authority at any point in the system's history was well aware of the health and safety conditions in the schools,' " the report concludes.
