There is no need for it. That Royal Assent requirement is both BS and law and needs to be done away with. But Canadians who love monarchy are happy to require others to 'swear allegiance to the King/Queen AND heirs' - which includes the pedophile Andrew. There really is no need for this third party to be involved in Canadian affairs. Yes it is in the constitution right now but if you have some self respect and feel that swearing allegiance to some other person is not in line with equality of human beings then you have to stand against it.

Props to Australia for taking the first step and making it not part of the citizenship oath. The other ties are still there but at least you are not making people swear allegiance.
