>- the US imports 60-70% of its oil from Canada

In context, this only applies to oil that the US imports. That number means that of the oil that the US imports, 60-70% of it comes from Canada. The US currently produces more oil than any other nation. Your note should read "the US imports 60-70% of the oil that it imports from Canada"

- 100% of the natural gas

As mentioned above, this means that US imports of natural gas come exclusively from Canada. The US currently produces more natural gas than any other nation too. Your note should read "100% of the natural gas that the US imports comes from Canada"

It makes sense that Canada is sole source for imported natural gas since that is a product that is most efficiently transported in pipelines, like crude oil.

The way your numbers are framed seems to me to imply that the US is a net importer of oil and natural gas when in fact we began to ramp up exports of oil and natural gas (and coal) in 2006-2008 time period. Those exports helped the industry remain a dominant political force and provided a lot of seed money for the corruption that we have seen in the US since.

And Canada has also been passing up an absolutely enormous opportunity for industrial growth by spending generations supporting American industry by remaining a primary resources economy.

Notably, none of the goods you just mentioned about (energy imports, uranium, potash, etc.) have had tariffs applied by the Trump regime because they know all this. And it would be political suicide to apply an export tax on them.

No, instead the Trump tariffs have specifically targeted the regions of Canada that a) elect left of centre governments and/or b) have manufacturing economies.

So Ontario's auto sector, BC's forestry, and Quebec's aluminum and aerospace sectors.

Meanwhile Alberta and Saskatchewan -- which have compliant quite honestly pro-Trump governments -- have only 2% of their exports currently impacted by tariffs.

It has the look of an attempt at regime change, masquerading as economic policy.

This is a useless hypothetical. Almost every country would regress in quality of life if it were suddenly cut off from the global economy. The options aren’t a bad deal from the US or complete isolation. Canada is making deals with reliable partners abroad.

By definition if you isolate a country from the world it would be more self sufficient that very moment than it is the moment before it is isolated. Isn't that obvious?

> The average Canadian has unwarranted sense of nationalistic pride about them (compared to their neighbors).

If you think Canadians have more nationalistic pride than Americans, you seriously need to get glasses.

Americans literally pledge themselves to their country every day of school.
