Interesting you say that, because as another Canadian, I would say that the sentiment in our country is the opposite of you describe. The actions of our government reflect it.
Canada is moving further from US, not closer. Canadians who support Americans are in the minority at the moment.
I'm not sure how a new US president would be able to turn it around.. further more, what's to say that the president thereafter will follow suit? How about the next 5?
The simple answer is we need constitutional reform. Term limits on SCOTUS, codification of norms (eg releasing presidential candidate tax returns, not blocking appointee confirmations indefinitely to steal the position for the next admin), anti corruption laws with teeth. Also things like reigning in the absurd executive power bloat that’s gone on since Lincoln. POTUS was never meant to be a king. There should never be a case where the executive can start a war (conventional, trade or otherwise) without even CONSULTING Congress.
