Cheaper foreign vehicles will also hurt the automotive industry in Ontario, Canada. So, this is an interesting move from the Canadian fed govt.
Canada has no domestic automaker and US automakers, under pressure from Trump, are closing some factories in Canada & relocating production to the US.
Yes, the Canadian auto industry will take a hit, but it already has from the US (and might take more).
If he has his way, Trump will kill Canada's automotive industry. If you accept this as forgone, maybe partnering with the Chinese to create a new auto industry is a good idea.
What automotive industry? Name a single Canadian auto manufacturer of significance?
Just because the companies building cars in Canada are headquartered in the USA doesn't mean Canada doesn't have an automotive industry. The factories, equipment, and workers are on Canadian soil could always be nationalized (not without retaliation of course).
