Right, so my point that Canada taxes those who are living outside their boarder stands.

And the US has tax treaties with other countries as well, so if you pay taxes in say Japan or Canada you do not pay taxes in America as well. Unless you make over 150k a year, then you only pay the marginal difference.

That isn't by tax treaty, which is usually related to payroll taxes. You can always deduct taxes you pay to any foreign government, with a couple of exceptions (Cuba maybe?), even if they lack a tax treaty with the USA.

The US taxes you regardless of (tax) residency. There is no such thing as a non-tax-resident in the US: if you're a citizen, you pay.

With Canada, you can be continue to be a citizen but (potentially) not pay. There is "potentially" with the US.

No it doesn't stand.It's different from the american system. Tax residency is a concept that many countries have, independantly from your citizenship.
