You're question was " why am I so afraid of Canadians jumping the border" correct?
They might smuggle bradoors and putine and not share with me. I'm not in fear of Canadians nor of them jumping the border. Maybe for whyskey in Detroit which I favor, Mapleleafs have it pretty good there. I like the country meaning the land, beauty, variety. My partner married and is "legal resident" if I have it correctly. Can work, has most of his firearms, has healthcare, can't vote. Canadas great.
Hear this. That dude, my esa' at work, backbone of the country, rock solid. He was two full years going south from the Arctic of America to Canada!
So I've been forethcoming and now I expect the same.
Why 2 years to have legal status in Canada from USA? I was sure our nations were better friends than that and I was wrong. Again. It Happens.
