3> They dislike the weather in Canada.
4> Their values don't line up with Canadian values (for example, Canada makes genocidal speech a crime -- some people put the bar of free speech higher or lower)
5> They like lower/higher marginal tax rates and the government services levels thus provided
6> They can't get in
7> They enjoy hearing about their nation engage in military conquest, or are more pacifistic than the Canadian government
8> They are working in a niche field where employment isn't availiable in Canada, gets paid more elsewhere, or is otherwise superior
9> They are in a close relationship with someone with one of the above reasons to not want to come here
10> Inertia
