RE:RE:PLI in your TFSAfdb, it's a question of facts. It's depending on the qualification of the goods you are buying. It apply to shares, but could also apply to properties, either rental properties or principal residence. If you buy shares with the intention to keep them for a certain period of time, it will be considered as a tangible assets, and will be subject to capital gain when they will be sold. If your intention is to buy and sell with an immediate profit in a short term period, the shares will be qualified as a good in inventory, and the the transaction will be qualified as a business income. The best example will be a day trader playing penny stock all day long. The more you are buying and selling stocks, the more your intention can be considered as a business transaction. This is nothing new, however, people try to use TFSA to avoid taxation. TFSA is there for investment income, such as capital gain, interest or dividend income. As soon as the nature of the revenues change, it's not tax free income anymore.
