its really easy for the usa to take over canada. most diplomatic visitor agreements are reciprocal, in this case the usa would fore go reciprocal to gain advantage in canada you cant give a benefit a citizen and not to the permanent resident in this case, since its the usa conferring the benefit, they can do whatever they wish if trump doesn't want low educated non english speakers at his southern border, why not take high educated, well behaved, english speakers from his northern voter? who would cross over first? the most conservative canadians in their outlook, i'm sure, except if they are moving to california. canadian and american culture have important differences but they are still the same culture. the same jokes. the same customs. mostly. so the usa allows people naturally born in canada to get a work visa that expires on 2034. no matter when they get the visa, all the work visas will expire on 2034. you say that they will see if they will issue them again in 2034 to 2044, but that's a trick. they are work visas so they are not eligible for welfare or any supports. if they hit hard times, then they must go home. as a result, the usa is getting canada's most productive workers. so 2034 rolls around and you tell them they wont extend the visa. obviously now all these canadians are pissed because they have to go back home. leaving their lifestyle, free speech, guns, good job, house, and other benefits. you suggest they have a referendum for canada to join the usa. of course, all these million of canadians that came to the usa would vote to join america, and also, all the immigrants to canada, are usually failed green card applicants to the usa, so canada was their second choice any ways, so theyd all vote to join america. only a small minority of canadians would vote to not join, and of course, you offer them benefits to entice them to come over. you can annex canada and get all their resources. no shooting required.
