And if there were not a United States there would not be a Canada auto industry.

Not so.
Actually, the one downside of the Auto Pact has been that at least prior to its inception Canada had the technology to and did build vehicles for its own domestic use from the ground up. Chrysler's (named for its founder - Canadian "Walter") tool room in Windsor Ontario was then the largest such operation in the British Commonwealth.
Otherwise, the Auto Pact has overall been highly beneficial for both nations and accordingly served as the prototype for NAFTA as it was originally envisioned by President Reagan & Prime Minister Mulroney.

Maybe you could elaborate on that statement.
Canadians buy approx 2,000,000 vehicles per year.
We also produce Hondas, Toyotas, Susukis here in Canada.
If we couldn't buy the 1.2M U.S. vehicles per year, why
couldn't and woudn't we build more of the other vehicles
available? How would the production of more Hondas, Toyotas etal
not qualify as "Canadian Auto Industry"?
I've driven mostly G.M. cars all my life, but a car built
in Canada is a car built in Canada regardless of whether it's
an American, German, Korean or Japanese company, n'est pas?
What am I missing?
