Why would any long serving Canadian citizen  defend Donald Trump? Give me one substantial reason? It hasn't happened yet but potentially, based on his rhetoric on free trade, devastate the Canadian economy. Not to mention his rhetoric concerning Russian and Putin. As you recall Canada is not in a position militarily to defend  itself from an Arctic Russian aggression. 
Donald Trump has not proven to be in any way presidential, aside from signing 24 Presidential Orders, none have been implemented as of yet by Congress. Plus he has divided, not unified America.
