No, it is exactly what happened, now documented in Canadian news media. More will be forthcoming as the incompetence of the Sunshine Band on NAFTA is revealed.
Canada is only 8% of North America's population and is very dependent on the U.S. export market (75%), just like the United Mexican States (79%)....the number that really matters.
Canada and Mexico have an order of magnitude less trade with each other than with the United States. Predictably, Mexico chose its own national interests over partnering with a Canadian dead end.
