There's lots of 3w & 5w, roadsters, 2&4 dr sedans running around Canada, pretty sure they weren't imported. Before the 70s 95% of cars built by the big three were made here. Other brands Nash, rambler etc were built elsewhere. What does it matter anyway? A 32 is a 32 is a32, more of them now than Ford ever built.
LOL my 3 plant number was no where even close. Both Ford and GM had and still have plans in the Kansas City metro.
