Personal Taxation Q 'n A

I sold some stocks at a loss in 2000, but have never had any gains since. I was told that I can use these losses against income in other years. How long do I have before I can no longer use these losses?

Losses from the sale of securities called capital losses can be claimed only against capital gains. You may carry these losses back three years or carry them forward indefinitely. If upon death, you have not used these losses, you may deduct them against other sources of income in the year of death. Please see CRA's discussion on this topic.
