his mother was born in canada, so he isn't an immigrant to us, he might be an immigrant to you, but do you usually revolve your entire ideology around immigrants based on canadian immigrants? no, because canadians aren't really immigrants to the us because our border is artificial. canada could have joined the us during the revolution, but the british simply retained various territories for whatever reason, and then loyalists from america moved north and created ontario which is our biggest province, so our founding population was "americans" more so than "british" in a sense as the people who settled canada as a new country did so from america, making us an american colony rather than a british colony in a way. interestingly while elon musk's mother was born in regina, saskatchewan, her father was born in minnesota, so elon musk's maternal grandfather was an american by birth.
