First of all, I would separate out sovereignty. My legal definition would be “the internationally recognized right to control activities in a given jurisdiction”. Canada has the right to control activities within that jurisdiction.
A different issue is the security and safety issues attendant with undertaking that role of enforcing our laws to make sure people are not polluting, and cruise tourism is being done in a sustainable way that's respectful of the environment and archeological sites and so on. I think that's a subset that comes.... Once we really recognize that we should have more confidence in terms of our sovereignty, we can instead put our energies into implementing a plan for dealing with safety and security.
I certainly think, over the last 10 years, the tools that have been developed, focusing on initiatives like the oceans protection plan, some of the Inuit marine monitoring plans, and long-standing initiatives like the Canadian Rangers—one of those great Canadian success stories in having human sensors in place to make sure that people passing through or coming to visit the region are behaving in a way that's in accordance with Canadian interests—are some things we're positioned right now to be able to take action on.
However, I don't think it's a sovereignty issue.
