Minister says unmarked graves at Canada's residential schools are 'tip of the iceberg'

Crown-Indigenous Relations Minister Marc Miller said Monday that the searches at Canada's residential schools were just beginning and that the unmarked graves found so far were just the "tip of the iceberg." He said there were upwards of about 140 former residential school sites across the country and while some operated for only a short time, there is still work to be done to get "to the bottom of things."
