Thats not what I was referring to, I'm saying if you lose money in your TFSA and you realize the loss, you will permanently lose that contribution room.
Example if you lose 1k and your contribution room is 10k, you've realized that 1k loss and now your room is 9k.
You can't re add that 1k you've lost. Its already accounted for.
Wait what do you mean? Trading inside of a TFSA? As long as it's not a business as per the CRA (which is a very loose definition) then he should be fine? I'm not an accountant and I'm not providing any advice but if one were to do a few trades a month, that should be okay no?
You probably shouldn't do this inside of your TFSA. You will lose the contribution room permanently. Just do a personal account bro. Then if you lose you can deduct it from your taxes.
