So the Royals Kate and Will arrived and left Calgary after a brief stay. They're a beautiful couple with promise to upgrade the monarchy's profile from bad to so-so.
Why do Canadians care?
I don't think it has anything to do with the Monarchy. Sure some older folks may have strong ties and reasons to be gung-ho for the Queen. But when it comes down to it I strongly believe the reason is based on the fact Canadians have very few big name celebrities, and the ones we do have who are Canadian either don't visit often, and/or don't live here.
So when we have world renowned celebrities show up, well, we get really interested. Anything that walks, has popularity, and is charismatic, well, we'll line up for.
So no, there' sno resurgence to the Monarchy, although no real push to become a republic either IMO. But we do like to catch a glimpse of the people we dream of being (in our dreams).
