I know that there is a limit in the contribution per year in a TSFA. At the moment (2016), if you have never made a contribution then you can contribute around $ 46 500.
BUT, even though all interests, dividends, capital gains, withdrawals, etc. are not taxable, does interest count towards TSFA limit? For example, if I contribute $ 30 000 and earn $20 000 in capital gains from mutual funds at the end of the year, will the contribution limit will be considered only on the contribution of $30 000 or in the total of $ 50 000?
