Just a couple of points:-
The reserve powers of the Crown are quite important and powerful. I don't have all the details at hand, but there are instances in our history where the Governor General and one or two Lieutenant Governors exercised them. Viscount Byng for one, and I think the Lieutenant Governor of Manitoba. And there was a Constitutional crisis resently in Australia.
It is quite conceivable that the present Governor General may have to decide whether to disolve Parliament and call an election, or call upon the leader of Her Majesty's Loyal Opposition to form a government, without having an election.
The idea of a royal taking up the position of GG is not new. In my younger days (back in the 60s, when some of you were not even a gleam in your father's eye

) it was suggested that Charles was leading a bored and unchallenged life, and perhaps a tour of duty in Canada as GG would spice it up.
Certainly we have had lesser royals as GG.
With a regard to only the Heir to the Throne having an income based on his position in the line of succession, I recall reading that when Prince Andrew went through his divorce, his wife's lawyers were surprised to find that the only real incomes he had was as a Commander in the Royal Navy. All the rest were bestowed at Her Majesty's pleasure.
Senator Forsey once wrote an article on the cost of Monarchy in this country, and if I recall correctly, it was very small in relation to other expenditures government made, and that was many, many years ago. With the explosion in government spending nowadays, I would suspect, that notwithstanding the apparent extravagant budget of the GG, the same results from a similar study.
On another note, and I hope it will not generate a long debate off topic, I note in reply # 36, back on 27 September, that pbi used the term WASP. I recall being at a government sponsored meeting in British Columbia a little over ten years ago when the speaker used that term most negatively, and often.
My challenge to her was "What does that term mean?" She stuttered and I replied that simply put "White, Anglo Saxon Protestant."
I pointed out that there were no Black, Red, or Yellow Anglo Saxons. And degrading Protestants could be interpreted as a hate crime. I say all this with tongue in cheek

, but I really don't think people realize what they are saying when they use the term, other than believing they are relating it to being some sort of bad "British" (only the Protestant "British", not the Roman Catholic, Muslim, or Jewish "British").
