Unironically it would be an immensely powerful nation. Good food production, good infrastructure, two of the three largest cities in the United States, many world class universities and research institutes, good mineral wealth as far as the industrialized northern hemisphere goes, lots of water, great commercial projection capacity, and a metric fuck ton of people. All without any of the dead weight states except Indiana. And all we’d have to do is deal with a bit of people who speak French poorly and a province that’s far more liberal than its insane government (ON, but swap province for state and that describes OH too)

It’d also be an absolute powerhouse of workers rights
