Frankly, the issues that Canada faces now stem from a long history of questionable policies, starting from when Diefenbaker shuttered the Arrow and stripped the talent and parts to be scooped up by Boeing, Lockheed et al all the way to when Mulroney & Reagan signed the FTA dooming Canada's private sector. None of this has been good for Canada's sovereignty and long term independence/success. A non-trivial amount of the SV luminaries that have started companies which showcase American inventiveness have a Canadian passport even though they don't advertise it.
The strained relationship with the US right now is actually providing ample opportunity for Canada to make some strategic long term bets without the "US foreign policy alignment" overhang. I'm optimistic.
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.
