I have a mixed attitude as to the role monarchy plays in Canadian law/politics, but it's exciting nonetheless for an heir to be born. My mother's family is very royalist so I grew up learning a lot about the monarchy. Diana's death hit my grandmother harder than the death of my great-grandmother a week earlier, for example. When she herself died, I inherited a very large collection of books on the Windsors and ther ancestors. So while it goes against my political ideology I've also been a bit of a royal watcher since I was a kid. They are quite the interesting group.
Any day now the new heir to the throne will be born, and that's pretty exciting! I'm hoping it's a girl - Queens in their own right seem to do the monarchy well.
