Ok, I guess your right. thanks for the links,

So in essence, the "gains" you make from your "over-contributed" amount is also taxable.

So if I have 30,000$ in TFSA then 10,000$ is over-contributed....dust the gains from that amount is going to be taxed. An example, cuu at 5$ a share is $50,000 investment income gain...this amount would be taxable under the new tax laws, this is what golfyeti is implying.

thank you for that information, I wish the TD guy told me that, he must have not known :/
