I don't know...they put up a fight against the USA. Maybe times are different today. I like to see it happen and Europe reaction, just seems like Canada is too much to just let go of with no fight. (all the oil and gas, plus the amount of land)
Just cause today the Queen is a level headed person and allows the 16 countries to be 99% free you could say doesn't mean it could not change later on after she dies. Even hundreds of years from now.
BTW...I am one of those "nuts" who still believe Princess Diana death was to stop her from having any more "royal children" to keep full control of the "family". (so keep that in mind ha ha)

Finance
The sovereign only draws from Canadian coffers for support in the performance of her duties when in Canada or acting as Queen of Canada abroad;
Canadians do not pay any money to the Queen, either towards personal income or to support royal residences outside of Canada. This applies equally to other members of the Royal Family.[19] Normally, tax dollars pay only for the costs associated with the Governor General and ten Lieutenant-Governors in the exercise of the powers of the Crown, including travel, security, residences, offices, ceremonies, and the like.
The provincial and federal governments keep records of expenditures associated with the Crown, but no official report on the full cost of the monarchy is compiled. Every three years, the Monarchist League of Canada issues a survey, based on the various federal and provincial budgets, expenditures and estimates, that outlines a yearly cost for the functioning of the Crown.
The 2005 survey found that the institution cost Canadians roughly $49 million in 2004.[20] Previous surveys found that the overall cost of the Canadian Crown was $22 million in 1999,[21] and $34 million in 2002.[19][22] (This does not take into account the inflation of the Canadian Dollar over these years.)
