Cooperation Agreement

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 agreement provided a mechanism for coordination and cooperation between the two governments for remediation and care and maintenance activities at Giant Mine.

Aboriginal Affairs and Northern Development Canada (AANDC) is overseeing the care and maintenance at Giant Mine. AANDC 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.

Other highlights of the 10-year Cooperation Agreement include:

  • both parties agree that the underground freezing method is the preferred option for addressing the arsenic trioxide waste stored underground at Giant Mine
  • creation of an interim office, acting as co-proponents for regulatory applications and overseeing site care and maintenance activities
  • creation of an oversight committee responsible for administering the Agreement and providing general direction to the interim office
  • the Government of Canada acknowledges long-term responsibility for the arsenic trioxide waste stored underground at Giant Mine
  • the GNWT will provide $23 million as its contribution to care and maintenance and surface remediation
  • working together to inform and discuss the remediation, and care and maintenance activities with the City of Yellowknife and the Yellowknives Dene First Nation communities of Ndilo and Dettah
  • the GNWT will provide the federal government, through the appropriate tenure instrument, with unrestricted surface access and occupancy on the site
  • both parties agree to maximize northern economic development opportunities in carrying out the Giant Mine Remediation Project
  • both parties agree the surface will be remediated to industrial standards.
