David Johnston's selection as Governor-General may be the first time the post went to someone after what can be seen as an audition. I mean his role in setting the terms of a public inquiry into the Mulroney-Schreiber affair.
I know he has a fine résumé: law dean, university president, publications, public service gigs, business boards, a bit of media exposure, some Harvard and hockey in his past. There are loads of achievers in this country with that kind of CV. But most didn't play a key part in a recent crisis that was politically charged for the government.
