I see only very minor downsides such as American patriots getting angry because they no longer have an individual America, the same with Canadian and Mexican patriots.
It would definitely cause economic booms, make it easier to travel within North America, and make North America the leading world superpower.
Keep all the Canadian, American, and Mexican provinces and states and call them whatever you want. Just try to eliminate small governments that are only part of a municipal branch to make money off of regional zoning and taxes.
