We'll see what happens when US tries to pass the new EV tax bill.No. It won't hurt Canada in the long run.
The biggest problem Canada has right now is the degree of dependence of trade with the U.S.
Right now, if the U.S. collapses into anarchy and civil war (quite likely, watching the present news...) it drags Canada down with it.
Were I Justin Trudeau, I'd be doing everything in my power to decrease trade with the U.S.
It will kill Canadian and most of the US Auto manufacturing though.
Building EVs is also dependent on Canada as we have all the natural resources needed to build them.
