It already says in the article they won’t be building anymore housing because they are forbidding cutting down trees to clear land to build, and they’re already out of open lots to build on.

This is 100% NIMBYs finding new ways to protect their property values.

Does this actually do that thought?

I would be very surprised if Quebec doesn't already have some longstanding clean water act type law that accomplishes the same "can't clear let alone develop land without our discretion and paying $$" type restriction that the NIMBYS are getting here.
