One would think so, but is that really true? Some numbers I just got:

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

- 100% of the natural gas

- 85% of energy imports

- 25% of Uranium

- 20% of all mineral imports, ahead of China

- the Great Lakes hold >80% of the USA's fresh water

- patrolling the almost 9000km border is mostly up to Canada

Despite the size disparities, they run close to a trade equilibrium: US exports $420B, imports $450B. There is a lot on the line for the US.

>- 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.
