title: Canadian Indian residential school system
context: In Canada, the Indian residential school system[nb 1] was a network of boarding schools for Indigenous peoples.[nb 2] The network was funded by the Canadian government's Department of Indian Affairs and administered by Christian churches.  The school system was created for the purpose of removing children from the influence of their own culture and assimilating them into the dominant Canadian culture. Over the course of the system's more than hundred-year existence, about 30 per cent of Indigenous children (around 150,000) were placed in residential schools nationally.[3][4]:2–3 The number of school-related deaths remains unknown due to an incomplete historical record, though estimates range from 3,200 upwards of 6,000.[5][6]
