Also that doesn't count people on islands who may be closer to American territory than any other good option for relocation.
What makes you so sure that it would be a bunch of South Americans looking for refuge in the US and Canada and not the other way around?
Also, you are aware I hope that it's not physically possible to migrate by land from South America to North America, right? Those 100 million would all have to travel by either sea or air.
