In 1996 Harvey Barracks and Currie Barracks (both part of the former CFB Calgary) were decommissioned and troops stationed at these facilities were reassigned to a base in Edmonton. The Black Bear Crossing area of Harvey Barracks became a neighbourhood within the nation when homeless band members took residence in the 180 vacant Canadian Army housing units en masse as the nation suffered a housing storage in 1998. Initially they were denied permission by both the Tsuut'ina tribal authorities and by the Department of National Defence whose lease was still effective. There were concerns that asbestos had been used in the insulation of the housing units and there was still unexploded ordnance in the vicinity of the neighbourhood. The Department of National Defence later relinquished control of the area, stating that there was no danger of exposure to asbestos. The area grew into a neighbourhood housing 800 residents and was served by the Tsuut'ina Police. However, in 2006, Health Canada declared the buildings unfit to live in, citing asbestos contamination, and the tribal council ordered the buildings evacuated. The housing units were demolished in 2009.
