Will Ferguson wrote a book named _Bastards and Boneheads_ [0] that told the history of Canada's prime ministers as one or the other. The bastards made history, the boneheads are remembered for their folly.

Mulroney and Pierre Trudeau were bastards, and supremely consequential in Canadian history. Joe Clark and Paul Martin were boneheads.

Which ones Harper and Justin Trudeau are may be too soon to tell, but Carney is clearly a bastard.
