Lord Dufferin
I discussed the history of the role of the Governor General of Canada with the National Post. In contrast to the United Kingdom, where the Prime Minister and the Queen meet on a weekly basis, there is no set precedent in Canada for regular meetings between the Prime Minister and Governor General. As explained in the National Post:
“However, prime ministers and governors general might become best friends anyway. Royal historian Carolyn Harris told the National Post that Sir John A. Macdonald and Lord Dufferin were so close that Macdonald became godfather to the governor general’s son.”
