If you bought the property prior to 1994, you may have already claimed an up to $ 100,000 capital gains deduction on the property. (moneysense.ca)
Any remaining capital losses may then be deducted from other sources of income, subject to a restriction based on the total capital gains deduction that has been claimed over the years. (taxplanningguide.ca)
Shares of a public corporation do not qualify for the enhanced capital gains deduction. (taxplanningguide.ca)
