As a Canadian, while I have much respect for the Queen, the royal family is still a distant entity and it will take a special successor to generate special interest in the role of the crown in Canada on a more mainstream level for average Canadians. The Governor General, the Queen's representative, is more important to me as she actually is Canadian and resides and represents our country, even if that role itself is somewhat contested as well. But I'll stop ranting about this - I'm a Political Science student here at Queen's University in Canada (ironic!) and I could talk about this for ages.
However, the push for a republic in Canada is almost non-existent in the mainstream, unlike Australia, so we here in Canada will most likely be seeing Charles as King of Canada should he succeed the Queen. I, for one, still can't respect Charles for his past discretions - after all, if he is to be the King of the country I live in and will be entitled to special privileges, then I expect his behaviour to be worthy as such. I'm not a fan of Camilla either and I feel that having Queen Consort Camilla, or whatever title she will adopt, by Charles's side if he is king, really isn't such a popular move in Canada either. I certainly do believe Canadians will be more receptive to William on the throne after the Queen than Charles.
