According to https://matadornetwork.com/read/where-canadians-live-south-l..., 70% of Canadians live south of the 49th parallel. That line is the US/Canada border for much of the country. (It isn't the border in the east, where Toronto, Ottawa, and Montréal are.)
Tipping points have ability to change our climate in a very, very short time.
For example, Gulfstream breaking or redirecting can be a sudden event. Many people forget that Europe is very far north compared to its climate. If you chose a lattitude so that half Canadians live north of it and half south of it, that lattitude would intersect Croatia, Italy and Spain.
A sudden break in Gulfstream would bring immediate step change to European climate, complete crop and extensive infrastructure failure.
