Thank you, Madam Chair. The other question I have is with respect to the monitoring and management is: is there any case law out there that's available, any challenges with upstream industries and that, doing work up there? Has there been any challenges from any of the Indigenous groups or the Government of the Northwest Territories to challenge? There's pulp mills or mining companies that may have potential damage for waters coming into the Northwest Territories. Thank you, Madam Chair.
