CBC – Star Blanket Cree Nation begins ground-penetrating radar searches at site of Lebret IRS that could take up to 3 years to complete. The school closed its doors in 1998 making it one of the last IRS. More than 55 acres on the reserve will need to be examined. Star Blanket has been able to secure agreements with some landowners as it prepares to search areas once operated by the residential school.
