Carney internally is playing to a domestic crowd that is actually more hardline on US trade policy than he has projected.
The issue with "bending the knee" so to speak is that the hardship is just as bad as the no deal situation, except with the worse outcome that Canada's future prospects for diversification are diminished.
There is hardship down both paths for Canada, but only one of those paths has a long-term future.
You're right that it likely involves a heavier investment in our own resource extraction, but that seems to be precisely what Carney is moving towards.
As for the amusing side-quip about Russia, chances are Canadians will likely look to emulate some other resource-extractive based economies, like the nordics. The issue is less the extraction and more how the wealth from that extraction gets hoarded. And there too, it would manifest as the need to move away from the American/Russian model of a small set of simple-minded, deranged oligarchs siphoning all the wealth in the economy towards themselves.
