See my post 13.
Ford is discontinuing all US market cars but the Mustang over the next few years and switching to an otherwise all SUV/CUV/truck line. GM is looking into doing the same because nobody wants domestic sedans any more, not in a significant and economically worthwhile to cater to number. Many of the vehicles being canned were Canadian built or had major Canuck parts.
Then you should email Trudeau and beg him to stand strong
against Trump, since you seem to think tariffs won’t hurt Canada.
