Interesting proposition, that. I've spent a lot of time thinking about whether to go conservative in my TFSA with the limited space, or to go aggressive and try to create explosive growth. I've come to a few conclusions:

1) TFSA is better than SDRRSP because I can bill trading expenses outside my account. This means I don't need to be as careful about my frequency of trades.

2) Since I don't pay tax on realized gains, I can buy and sell a lot more than in my regular trading account, without paying a price.

3) I'll put some junior exposure in, because if I could get explosive growth to a point where the account actually becomes substantial, and is out of the taxman's clutches, I would be laughing. Also because I am more likely to want to actively trade juniors.

4) I will transfer shares in, because then I can transfer shares from as many companies as I want for $5000.00, where I am limited if I try to buy (especially mid/large cap) with only $5000.00.

Any other thoughts I've missed here?
