RRSP is a 401(k) with a few nuances.
1. You can withdraw from it anytime but will have to pay taxes. I guess this would be when it matures and before it is reinvested.
Its counted as income, you will pay regular income tax to the IRS. You may be paying 25% to the CDN government.
2. The taxes are on a sliding scale based on how much you withdraw with the lowest level being 5% in QC and 10% elsewhere in Canada.
That's the withholding tax, its just a token amount upfront so that you don't get a large tax bill. Do not worry about QC anymore, its no longer relevant.
3. We live in the US, which of the rates would apply? My husband was only ever is resident of QC but obviously does not live there now. Is there any other Canadian tax applied to this if we don't have other Canadian income.
You don't pay to the province it was started in. You only need to worry about federal tax at this point.
4. The only thing I can see about when you can withdraw without that penalty is after 71 years old, this feels very late. What is the age at which you can withdraw without penalty?
Any age. We don't have age rules. The only penalty you face is don't withdraw when you have high income cause it boosts your income...
5. Lastly, Is there a better way to manage these? A Canadian brokerage, etc?
Questrade. A self directed brokerage account.
Thanks for the help MMMers! I'm just trying to clean up our accounts and this is the last set that confounds me.

"In some unique situations, former residents of Canada might be able to file a Canadian income tax return as a non-resident under Section 217. Filing a return under this election allows a non-resident to file a Canadian tax return if it would be beneficial for them to do so. In this case, the non-resident taxpayer would be able to claim the same deductions and credits as that of a traditional Canadian taxpayer. There are limited reasons for a non-resident to make this election. One reason is when an individual has a non-working spouse in the U.S. with, for example, $50,000 in their RRSP. In this case, the individual could withdraw the RRSP tax free over five years without paying any Canadian income tax."
