On March 15, 2005, the Government of Canada and the Government of the Northwest Territories (GNWT) signed a 10-year Cooperation Agreement on the management and remediation of Giant Mine. This was renewed on July 13, 2015. This agreement provided a mechanism for coordination and cooperation between the two governments for remediation and care and maintenance activities at Giant Mine.
Indigenous and Northern Affairs Canada (INAC) is overseeing the care and maintenance at Giant Mine. INAC and the GNWT worked together to develop a Remediation Plan to address the entire cleanup of the site. The top priority for both governments is ensuring the health and safety of the public, and the protection of the environment.
