Yes, I think that certainly is a point we've been thinking about quite a bit, because clearly on the defence side there are arrangements in place, and there is a much clearer kind of situation that exists there, but what we've been looking at most recently—and we've been having discussions with the U.S. about this—is the whole notion of security in a different sense: when we talk about supply chain security, when we talk about supply chain resiliency and when we talk about critical minerals we might supply to the U.S. and important imports we get from them.
It is security in a different kind of sense, but it is something that we're spending much more time on, because we both want to have secure sources of supply that would allow our economies to function without getting into some of the difficulties we've seen, and supply chain security can lead to that. With Canada and the U.S. being such long-standing, secure economic partners, it's ideal for the kinds of products we trade back and forth to have that kind of situation exist, where we're doing this on a security basis. It's definitely something that we've been talking about.
