The fourth volume of the Truth and Reconciliation Commission of Canada's (TRC) final report, dedicated to missing children and unmarked burials, was developed after the original TRC members realized, in 2007, that the issue required its own working group. In 2009, the TRC requested $1.5 million in extra funding from the federal government to complete this work, but was denied.[1] The researchers concluded, after searching land near schools using satellite imagery and maps, that, "for the most part, the cemeteries that the Commission documented are abandoned, disused, and vulnerable to accidental disturbance".[7]:1 Thus far, they have been able to identify names and other information of at least 4,100 children who died in residential schools.[8]
