Thank you.
We've heard that our defence of North America and the defence of our own sovereignty really takes a system of systems. We heard about the fact that the north warning system is going to expire in 2025. Given the realities of climate change, the accessibility of the Arctic passageway, and Russia's and China's interest in our north, could you elaborate on what you would recommend for us in terms of the northern passageway and surveillance in the north and its importance?
