Even if the deployment was planned before hand, the nature of the press release and the participation of the Minister was clearly directed to a particular audience, in the Kremlin, not in Canada.
The Russian reaction to Georgia's attempts to re-assert control over Ossetia was a message itself in two parts. The first was to the "near abroad" of the former Soviet/Russian empire, reminding them that Russia does not consider their independence to be absolute. The second part was to NATO, advising them that Russia's self-declared interests in regions like Serbia cannot be ignored, as it believed NATO did when it allowed Kosovo's independence.
Canada's announcement, re-affirming our committment to Kosovar independence and our active participation in NATO's promotion of that independence is a message back to Russia in that second message. Even if a small gesture, the Russians will understand what it means. (Mind you, they may not notice right away since they are going to be having fits of various sizes over the defiance of Poland and Ukraine.)
