There are four different phases of Operation Nanook, and for a full explanation of that I would refer you to our friends from CJOC to give you the in-depth answer.
Having had experience with the nature of operations up there, I will say they cover the full realm of operations that we might have to conduct in the Arctic. They include all whole-of-government partners and the local territorial governments and indigenous partners to make sure that we are looking at security in a very comprehensive manner. The level of effort that we've put into those operations has grown over the years as we gain more understanding of the region and a better appreciation of the types of actions we might be required to take up north. Those could range from search and rescue to detecting and reacting to adversaries, but most of our focus is on sovereignty and security-type operations.
