A Métis archeologist at the University of Alberta working with the Muskowekwan First Nation in Saskatchewan may have discovered graves of missing children from the nearby residential school that closed in 1997.

“In the records there were 35 children who were unaccounted for, that disappear off the records, and nobody quite knows what happened,” said Kisha Supernant. The Muskowekwan Residential School operated from 1889 to 1997 and stands on the land of the Muskowekwan First Nation, which is trying to save the deteriorating building—one of the last standing residential school buildings in Western Canada—to turn it into a museum.
