I think that Canadian monarchists are sometimes completely unaware of the fact that to people who come from elsewhere almost nobody considers the British monarch to be the Canadian monarch.
------------
Most Canadians while accepting the Queen as the Canadian head of state don't consider themselves "monarchists", a term I would reserve for those who get moist at the idea of monarchy.  It's one of those weird facts of being Canadian that make us who we are.  Most (I presuming here) are uncomfortable with those who make a fuss about the monarchy one way or the other - sensible Canadians just don't care and seriously suspect the motives of those who do. Happy Canada Day!
