I think it is a case of popular politics but poor policy. It appears like Canada has decided that they do not want to be in resource extraction for environmental purposes, but in their bid to be socially responsible, they are for the most part ignoring the potential political and social fallout of such a policy. Sure, it will make oil and gas operations more untenable in Canada, but ultimately that probably wont matter much since other producers that already dictate the price through cartels will quickly fill demand to their own benefit.

Whether or not people want to think about it, Canada exports a lot of natural resources, and if they want to stop, which is fine, they better have a real plan for transitioning those industries, and have an idea of what they will do in lieu of a that huge chunk of their exports going away. Its really easy to say something like "just transition away from oil" but history has shown that it is very difficult to do, especially for a province beholden to federal policy.

These costs are massive but are largely being ignored, or just offloaded as only Alberta's problem. They are running the risk of hollowing out a huge portion of the economy without any real plan which has pretty severe consequences as seen in places like the rust belt, which will end up sowing the seeds of populist resentment amongst communities that will feel used and abandoned, especially in places that already feel largely ignored by federal politics like western Canada.
