Check your schedule 3 and delete any response there if you did not sell your home. Leave it blank. Then you can choose refile.

Thanks for the reply. When I checked the Schedule 3 form it says at the top - "DRAFT - Do Not Send To CRA Capital Gains or Losses". I have a loss on Part 3. I assume the Draft form is not finalized for some reason, likely the new capital gains tax. What do you think?

If you have an actual loss, then yes. The form will be complete by CRA sometime this month, I believe.

Thank-you
