Recently the department of defence announced a plan to pour billions of dollars into Northern security. And there's no doubt that in a changing world the Arctic region has become more important, for Canada and our allies, as well as for our adversaries.

What does the DoD plan to use that money for, exactly? And how will it work with the Indigenous people who live in the region?
