Even without Trump, US-Canada trade was on track to hit choppy waters. Even in the Biden admin (whose alums would have ended up in a Harris admin) there was an openness to armtwist Canada [0] into acquiescing [1]. China did the same [2] with Canada [3][4] until they acquiesced [5]. Heck, even the EU has been slowrolling the ratification of the EU-Canada CETA [6] to protect their (primarily French and Italian) industry.

Sadly, it's difficult for a country that is Canada's size to push back when faced against these sized economies.
