how long is the Shrew of British Columbia allowed to stay in Canada without a visa?
I would imagine as royal/non royal as long as she wants. Her show Suits was shot in Canada for the most part and she sort of lived here. She apparently became good friends with the wife of the son of ex PM Brian Mulroney while here. That said I think this stay in Canada is a way station for her and she will return to the US at some point.
They can’t stay permanently. Canada law won’t allow the royal family to do so as that would be encroaching on their commonwealth status or something. I think they can only stay six months and then move out. Don’t know how long they have to stay out before moving back. She’ll probably claim any 2 day visit away is enough to start the clock again.
