I think there are a lot of different options being considered as part of that modernization, both for NORAD and for a wider set of efforts around continental defence. I hope we're going to see something quite soon.
What was laid out in a letter between the Minister of National Defence at the time and the Secretary of Defence from the United States—the day before our last federal election, I think—covered the waterfront, both literally and figuratively, in terms of what kinds of options Canada can contribute toward, along with the United States. There was a range of things: enhancing our Arctic infrastructure; improving the functionality of our forward operating locations, potentially putting one further north, for example; and replacing the north warning system with a range of modern systems to, with today's technology, provide the same function that the north warning system provided before, which is to be able to detect the key threats coming towards North America. I think there are a number of other investments we should look at in terms of command and control and various things like aerial refuelling tankers.
Hopefully that gets us—
