Canadian Politics Today

I used to wonder why we needed a monarch from another country in our governance until I gained a better understanding of why 1st nations are so supportive of retaining the monarchy. Canada's indigenous peoples amongst others...

...generally view the affiliation as being not between them and the ever-changing Cabinet but instead with the continuous Crown of Canada, as embodied in the reigning sovereign.

I like seeing for example the Queen raps Bojo's knuckles for his misbehaviour and I'd be even more supportive of a monarch that took up a similarly moral/ethical stance when the excesses of leaders and or governments in sovereign jurisdictions it helped establish around the world get out of hand.  I think this role for a monarch falls far enough outside the tradition to not get involved in politics and would remain there so long as the privilege or prerogative to speak up on occasion wasn't abused.
