It's not lunacy.
If you want to day trade, go for it. Lose, gain, whatever. But you don't do it in a tax-sheltered savings plan. Day trading isn't "saving". You're looking for a way to avoid paying tax on your capital gains, not trying to save money which is the purpose of the account.
I would check here instead:By the way, I checked the CRA website and none of the situations where a TFSA might attract tax was around day trading.
$6,000Anyone know what's the contribution room would be for 2019 TFSA?
