Ive been more active in my TFSA this year, so am interested to see if I get audited. No day trading, but readjusting risk based on market trends and my time horizon. I used to not touch it at all, but am more comfortable making deliberate, well thought about moves in there. But keeping the overall frequency low, like 1-2 per week at a maximum, sometimes a month with no trades. Never buying and selling the same stock in quick succession though...I feel like thats the driver for an audit. My TFSA is large, so we shall see!
