Non-medical withdrawals, even if over 65, will be considered income in both US and Canada (include on pension line). You can use the US tax and penalties as foreign tax credit.
Roth withdrawals are included on the pension line as well, and then the non-taxable portion would be deducted on line 25600, as treaty excluded income.
