By air yes. Requiring a passport between Mexico and US for surface travel will most likely happen.
Passport requirement between Canada and the US either won't happen or may be reduced to what they are calling" passport lite" There is a lot of cross border commerce between the US and Canada, a lot of US border towns depend on business from Canadians especially in the Northeast . There is a big fight going on now to prevent the passport requirement.
I go to Canada all the time . I usually carry my passport along with my drivers license because it gets me through Customs a lot quicker.
