I can certainly say that we see the military buildups.
With respect to Russia, their buildup is in their own Arctic on their Arctic territories. Once again, from a purely military point of view, we don't detect that land-based or sea-based buildup as a direct threat inasmuch as we don't perceive the Russians trying to initiate an attack against the Canadian north. That said, the political disposition of Putin's Russia does give us concern, and we've seen that they have very little to no regard for international law, so even though we don't see the material buildup prima facie as a particular threat aimed at Canada, we do see the politics surrounding that kind of military buildup as a matter of concern.
As for China, once again we see the threat as not military—not kinetic, as such—but we have seen nefarious Chinese activity aimed at Canada through hybrid threats, through cyber activities and predatory investment attempts, so we are monitoring those issues very carefully.
