Everything has tradeoffs. Various studies of the economic impact of climate change suggested some warming would be a net positive for northern countries but sufficient warming would be universally bad for every country. We have already reached that point, the issue for the north isn’t just an increase in average temperatures it’s an increase in variability. Canada wasn’t prepared for 120f temperatures and spending money to prepare for such rare events is hard to justify. On the other hand failing to prepare has real consequences.

Plus, retreating permafrost is a serious issue for infrastructure built on top of it. Combined with new pests and everything put together it’s a complex issue to analyze.
