Far more land in the northern part of the continent than further south. South America is the other way around. The largest part of the continent is towards the warmer part.

Even if a shift 20 degrees south were to occur, South America would still have relatively more influence from the Atlantic Ocean than Antarctica. North America's large landmass in the northern section is one reason for cold air masses being able to make their way as far south as Florida.

True, would that mean North America would get even warmer than it should for a 20 degree shift, as there won't be any large significantly cold landmasses to cool the more southerly areas

Canada would be a subtropical paradise and the most livable country in North America.

Well, one thing to consider is this. There will be more water between North America and the North Pole. And there will also be water between North America and South America.

This shift would be absolutely awesome Parts of Southern Ontario would be in the tropics and Northern Canada would actually become inhabitable

I hope you like a tropical desert, Vancouver would be a little warmer than this:
Ensenada, Baja California - Wikipedia, the free encyclopedia

South Canada would be a nightmare, albeit much better than the U.S.

Places like Churchill, Manitoba (on the Hudson Bay) would look more like this:
Annapolis, Maryland - Wikipedia, the free encyclopedia

I wonder how much the standard deviation of winter temps in North America would decrease in this scenario

That would be FREAKY. Like a parallel universe, Iqaluit, Nunavut would have hot weather in the summer and become one of the largest cities in Canada. Toronto would look something like Mexico City. Words cannot describe how bad I would feel for people in Chile and Argentina, I wouldn't complain about Canadian winters ever again knowing what they will have to go through. Everything would be a mess and poor penguins!

I think Rio~São Paulo will have similar averages and features of Washington D.C.~NYC without exposured occasional extreme low temperatures in winter and the Federal District of the Brazil(Brasilia) have 5~7°F colder than Canberra generally.

Maybe Rio would be llike: Puerto Madryn - Wikipedia, the free encyclopedia but less mild and a bit wetter due to being further from a rain shadow.
