Try googling the term "Doukhobor;" they're a Russian sect that has a sizable contigent in Canada -- they sort of remind me of Russian quakers...
And, just to offer a completely unsolicited and pompous opinion, I think the whole queen bit is a load of cr@p. What the hell has British monarchy done for anybody that's truly beneficial in the past 50 years? Canadians unite; overthrow your imperialist oppressor!
And as far as defense (or defence if you prefer
) goes, I don't think that having the queen is going to make you or break you. There's always been, and likely will be for a long time to come, a positive relationship amongst the Commonwealth, right? And besides, there's always that whole NATO thing... and Anne Murray/ Brian Boitano hitting clean-up.
