Is FBAR needed if a Canadian Retirement acct is fully cashed out and over 10K?

[MinhT1]

Yes.

If the retirement account has been cashed out and now is in a Canadian bank account with a balance of more than $10,000 at any time during 2025, then a FBAR has to be filed.

You can file the FBAR online HERE.

The Canadian Retirement account was cashed out and received a paper cheque which was brought straight into US bank. There was no deposit from Canadian Retirement acct to Canadian bank. Still need FBAR?

You still need to file FBAR.    The method you used to move the money (a paper cheque vs. an electronic wire) doesn't change the fact that the money lived in a foreign financial account for part of the year.
