Way I figure it, so long as it's not openly funded/led by Americans, they'd have to let it be. Quebec, and probably the maritimes, would likely revolt if they tried anything against something peaceful. Of course, anything armed, and all that goes out the window. They actually had a decent minority wanting such an annexation on the prairie until the 40's, so it's possible.
