Flags at Thunder Bay Regional Health sciences Centre and Thunder Bay Regional Health Research Institute will be flown at half-mast from May 31st to June 8th to honour the lives of 215 children found in a mass grave at the site of a former residential school in Kamloops, B.C. The flags will remain lowered for one hour for every child whose life was taken, and in memory of the thousands of children who were sent to residential schools, for those who never returned, and in honour of the families whose lives were forever changed.
