We can't afford to cut all ties with United States due to our geography and history, however it would be prudent for us to reduce our dependency.
I don't think majority of Canadians wish to see the nation in such a vulnerable position again with regards to US. Banking on a single player in terms of security and trade has proven to be a risky endeavor.
I have much love for the American people, but I support the actions of our government.
When a Canadian new grad is faced with an option of going to work in SV or in China which do they prefer? Between Chinese values and American values which do we prefer? A society with no freedom of speech? Where people are arbitrarily jailed if they voice an opinion against the government? Where the government places citizens in concentration and re-education camps and runs them over with tanks? I mean to me the choice is clear.
How many large American companies have offices in Canada? How many people and what slice of the economy does this support? Lots.
So yes, the US has drifted and is drifting from the ideal. And maybe it was never the ideal. But it's much closer to us than China in every imaginable facet and will likely remain so for the next many decades. We need to filter the noise out, definitely stand firmly for what we believe in, but also compromise and look at the longer term.
Beyond that societies can change quickly. Germany, Japan, Spain, Portugal, Argentina, Peru, Chili, South Africa, every country in the USSR, and China too have changed values dramatically in short periods of time in the past 100 yrs.
Also, China is not putting out videos that say they will dominate any country in the Americas. I'd urge us to take people seriously when they say what they value: https://www.youtube.com/watch?v=V359k45CBY0
I don't have a quantitative way of measuring this but I disagree Europe and Canada are closer in values. Canada has some "Europe" in it but a lot more "North America". If you put a random American and a random Canadian in one room they'll have a lot more common than a random Canadian and a random European. Random examples are suburbia and gun ownership.
Many Canadians are dual-citizens. About a million US citizens live in Canada. Many Canadians work and travel to the US. Business, personal, family relationships etc. Similarly about a million Canadians live in the US.
I've worked a lot with Europeans and Americans (I still do, I work for a large American company with offices in both). I've traveled to the US and to Europe. If you've done that a lot then you know the difference in feeling and culture.
The facts are still the facts. People like you can fantasize that somehow going over the ocean to remote countries can offset going over a truck to the world's largest economy. Or ignore the ways that our economies are so tightly coupled.
I just listened to Carney talk about this and at least he's more or less a responsible adult. He said we and the US share a lot of common thinking and values and he would like to work with the US. Where he draws the line is when the US tries to take away our ability to make independent decisions. And that's fair. But it doesn't sound like he's aligned with you and so I can only guess where your politics lie.
Learn from what they did well and what they did poorly, copy the good parts.
there's plenty of barriers without tariffs holding up trade between blocks and countries.
