and eventually had his government prematurely removed because he wouldn’t.

Not to be a jerk about it, but you sound like you're living in a different Canada from me. He was removed because he had become massively unpopular with voters and the Liberal caucus didn't want PP.

I don't personally know Trudeau, but my perception was that he wanted a majority from the snap election, not that he hated dental care.

Carney is not passionate about the environment.

He worked at government and NGO climate-related posts after his time central banking. Reporters that actually talk to him off-camera say he's passionate about the climate.

He literally passed a bill that allows the private sector to ignore environmental regulation so they could build a pipeline,

Conditional on something that will never, ever happen. Danielle Smith thinks she can get BC and coastal First Nations signing up, but she thinks a lot of weird things.

and he cancelled most of Trudeau’s environmental policy.

My impression is that it's mostly still standing. The really publicised and understandable planks like the consumer carbon tax were retreated from, but most of what can't be turned into a slogan, stayed. That being said, I couldn't name every Trudeau environmental policy off the top of my head.

and forced the NDP into oblivion because they abandoned their voters and tried to occupy the old Liberal space.

Again, that sounds like a different country with different polls. The NDP hasn't suffered for being too far right in my time, and if they hypothetically were to, the Green party is right there. They actually lost a lot of seats to the Conservatives last election.

I'm not sure Pierre ever was as deep in the centre as Carney is now, and I doubt it, but in any case the reason he's gone way to the right is because that's the global Conservative zeitgeist, and his base demands it. He paid for it at election time.
