Work is being done to identify students buried at the Brandon Residential School.
The school operated from 1895 to 1972, and no one knows how many children are buried there.
In a project called the Brandon Residential School Cemeteries Project, researchers from Simon Fraser, Windsor, and Brandon Universities are working with the Sioux Valley Dakota Nation to identify the children.
The project comes after the remains of 215 children were found in a mass grave at a former residential school in Kamloops, but investigations into the unmarked graves at the Brandon school started in 2012.
The death records of 70 children were found, but there was evidence of other graves.
