In 1986 , the Tsuu T'ina authorities under the leadership of Chief Roy Whitney took the initiative and founded an ordnance disposal company entitled the " Wolf 's Flat Ordnance Disposal Corp " . In the 1950s , 3 Tsuu T'ina citizens , a grandmother and her grandchildren where injured while berry picking . Her grandchild examined an explosive which detonated . The accident prompted the foundation of the service which was named after an honored elder . The company is expected to flourish as land leases for military bases across North America expire . The company has gained a worldwide reputation and serves countries which suffer from unexploded ordnance on their lands . After decades of extensive ordnance clearance by the company and the Government of Canada , occasionally live ordnance is still discovered . In 2013 , a tank shell was uncovered by summer floods
