I have maxed out my TFSAs every year and made sure do a lump sum contribution at the beginning of the calendar year- current balance is just over 80K.  All I use is a simple (all be it  aggressive) couch potato portfolio using TD Index E Funds.  Super simple, rebalance  when I make my annual contribution and forget it.  They should have called it a Tax Free Investment Account (TSIA), which might have encouraged more people to invest and not just treat it like a savings account.
