With regard to climate change, I would say we continue to monitor the actual conditions. Specifically our interests are in the ice conditions with respect to navigation capability, so I think that's where a lot of the focus is. We work very closely with, as I mentioned, Inuit, first nations and Métis, and we listen a lot to their perspectives on what they're seeing in their individual communities. We are incorporating that feedback into any conversations around new infrastructure that could exist in a certain location and even places where we might make future investments to support our polar icebreakers or the fleet of the future, and where the best locations would be, given the understanding that the climate is evolving.
The other thing I would say specifically with regard to our national shipbuilding strategy is that we're building ships for an uncertain future. We have a very good sense of what our mandate is today, but we also appreciate that over decades that might evolve and change, so we're trying to build ships that are going to be adaptable with the modularity that's essentially going to allow us to have the right asset for whatever the Government of Canada asks us to do in the future.
