As per CRA- If you sold more than one property in the same calendar year and each property was, at one time, your principal residence, you must show this by completing a separate form T2019(IND) for each property to designate what years each was your principal residence and to calculate the amount of capital gain, if any, to report on line 15800 of Schedule 3 Capital Gains (or Losses) in 2019.
