@Dozer,
You really make it sound as though it has to be one or the other whereas the far more logical assumption is both. It makes perfect sense that Canada would have sent a contingent to dawn as part of the ariadna mission, but they would have certainly been a minority group, rather than one of those that formed one of the Ariadnan nations; however, no country involved in the project would have sent their entire populace, which leaves the nation of Canada still on earth which eventually comes under the control of Pan-O. Meaning that their would likely be Canadian elements of both major powers. Although both would be fairly minor.
But I still agree, give us some Canadian style troops!
