CPP/OAS/SS are simply excluded from reporting on your 1040. So there is no need for any 1116 for these items, since there is no US tax to recover.

1. It should have been included on your 2021 1040 (if you chose to file a 1040 that year), or definitely on 2022 return.
2. As the Rev Proc points out, the treaty article is XIII(7).

Your 25% tax (or 15%) from RRIF will never be lower if you move back to Canada, no matter how slowly you withdraw the funds, unless that is your only source of low income, which, by judging from your current income, is very unlikely.

No. You would need to report it on FBAR, but it is not a trust by US standards.

In the years following the transfer, you will not have to include that Cdn account on FBAR.

Residency is based on.... residence. What were your LIVING arrangements since Des 2022 in Canada and US. Your employment matters little.

You report the income as if the RRSP was not tax-shetered, year after year.

They are from US corps. 10% flat taxed.
