Granted. We all know that whatever you withdraw from an RRIF is fully taxable as pension income and may or may not affect OAS Clawback. My point was that for stocks left in an RRIF you effectively pay tax on 100% of any price recovery (capital gain), i.e., pension income, as opposed to only paying tax on 50% if the price recovery (capital gains) are realized in a taxable account. With the down market and the ability to transfer stocks at the "low price of the day", there is an opportunity to use less of your minimum and to transfer some potential future gains out of the RRIF into a taxable account where any recovery in the price of that stock will save you taxes on 50% of that recovery.
As to OAS clawback, it is always a consideration regardless of the amount that you transfer from a RRIF. By the same token, anyone in that position also has the ability to consider "Pension Income Splitting" if they have a spouse and this can result in a reduction of the OAS Clawback.
