Northern portions of Tsuut'ina land were leased by the Department of National Defence and used to train Canadian Army personnel in live fire operations between 1901–1996. The Harvey Barracks camp, "Camp Harvey", was a 380-acre parcel. The Tsuut'ina Nation resumed sovereignty of Harvey Barracks in 2006 after the Government of Canada conducted de-mining operations for 15 years to dispose of unexploded ordnance, such as artillery projectiles, mortar shells, hand grenades, and live cartridges. Altogether 12,000 acres of land were returned to the Tsuu T'ina Nation.
