Who We Are

The Giant Mine Oversight Board was established as a condition of the Giant Mine Remediation Project Environmental Agreement.

This multi-party agreement was signed on June 9th, 2015 by the Government of Canada, Government of the Northwest Territories, Yellowknives Dene First Nation, North Slave Métis Alliance, Alternatives North and the City of Yellowknife. Incorporated under the Societies Act of the Northwest Territories, the Giant Mine Oversight Board is established as an independent entity administered by a six-member Board of Directors.

The Board has a storefront office located downtown Yellowknife, NT for both its administrative function as well as for the distribution of public information about the activities of the Giant Mine Oversight Board and the Giant Mine Remediation Project.

Ken Hall

Ken was born in Yellowknife and grew up out at the Giant campsite. His family has a long history of working and living at Giant. Ken holds diplomas in Ecology and Environmental Sciences from the Northern Alberta Institute of Technology and was the first environmental technician at Giant in the 1970’s. His career included time with Fisheries and Oceans when he travelled and worked throughout the Central Arctic spending time in many small communities. He went on to become a hazardous substance/contaminated site specialist with the GNWT then managed the environmental protection services until he retired in 2011. Working in both industry and public service with people from across the North has helped him develop a balanced perspective.

Vision, Mission, Mandate


The remediation of the Giant Mine site, including the subsurface, is carried out in a manner that is environmentally sound, socially responsible and culturally appropriate.


The Giant Mine Oversight Board independently monitors, promotes, advises and broadly advocates the responsible management of the remediation of the Giant Mine site. It also manages a research program focused on finding a permanent resolution for the management and disposal of the arsenic trioxide stored underground at the Giant Mine site.


The Environmental Agreement requires that the Oversight Board:

  • review and make recommendations regarding the annual report from Indigenous and Northern Affairs Canada (INAC) and the Government of the Northwest Territories (GNWT), the Status   of the Environment report and the 20-year Independent Project Review report;
  • participate in and provide advice regarding the process followed by the GNWT and INAC for assessing options for the management of Baker Creek;
  • manage a research program focused on finding a permanent solution for dealing with arsenic trioxide stored underground at the Giant Mine;
  • promote public awareness of itself, the Environmental Agreement and the Board’s roles under the Agreement;
  • establish a publicly accessible repository of records that it considers relevant to its responsibilities;
  • provide all its reports and evaluations to the Parties to the Environmental Agreement and make them available to the public; and
  • issue a report and hold a public meeting annually.
