Canada accepted responsibility for the Cantung site in November of 2015. Care and maintenance at the site continues to be monitored by the court-appointed receiver, for the North American Tungsten. The Government of Canada is bearing the costs of that work. The GNWT no longer exercises delegated authorities at the site under the Mackenzie Valley Resource Management Act. This means that it is Canada, not the GNWT, who is responsible for the decisions and water licences and inspections of any water licences or land use permits.

The final step to be completed in this exercise is the relinquishment of the site to Canada, and most parties are working closely to complete the legal steps necessary to transfer the land back to Canada, as it is their responsibility. With respect to the Mactung ITI is the department lead on that project and they are working closely to ENR to remove and dispose of debris from the site.
