Hi, Sale of my principle residence. My total cost + the capital expenses are $240K, but I sold it for 230K. Where I can show the loss of 10K Thanks Sairam

If you sold your principal residence, there is no capital loss or gain. The CRA just wants you to report the sale.

To do this you click on "Investments" in the "Income" menu. Check off "Dispose of a property, that was your principal residence" and click the "Continue" button. It will come up during the interview.
