Curren tly 50.00% of realized capital gains are taxed in Canada at an individual's tax rate. Some exceptions apply, such as selling one's primary residence which may be exempt from taxation.[2] Capital gains made by investments in a Tax-Free Savings Account (TFSA) are not taxed.
For example, if your capital gains (profit) is $100, you are only taxed on $50 at your marginal tax rate.
