There is that, but I don't think I'll be in the same tax bracket as I am now (the highest) when I have to pay that tax. I do put my biggest growth names into my TFSA, but keep my dividend payers in my non-registered account.
Interesting that. My wife thought the same thing but with income splitting, she wound up in a higher bracket after she retired and converted her RRSP to a RRIF. Because of that she has been taking out the minimum every year, but in those four years the thing has still grown by over 20%, in spite of her making the minimum withdrawals. Before someone says cry me a river, I realize it is a good place to be but she would have been better off contributing to a TFSA all those years, had they existed.
