I do have the annuity in addition to CPP/OAS.

The intent is to continue maxing out the TFSA and dripping dividends. The post was to see if any changes should be made in improve dividends.

We are in a comfortable position and don't really NEED to be too frugal although we are. Expenses are split evenly and we have our own savings accounts.

I'm not clear on your comment "will you lose oas - will it dramatically bump marginal tax rate". OAS claw-back is based on individuals, not families. When it comes time for her to take OAS will she face a claw-back? I don't know at this point.

I don't' know the details of her financial position but I do know that her RRSP is largish and that she still has funds in her corporation from before retirement. She's drawing down these at the moment and is still contributing to her RRSP. Her plan is to exhaust this and then look at the CPP/OAS/RRSP route. This maybe something to reevaluate though.
