Deduction for Losses from Other Years, Other than Net Capital Losses
You can deduct the following losses, provided you did not deduct them in a previous year:
- non-capital losses
- farm losses and restricted farm losses
- limited partnership losses
The amount of non-capital losses can be calculated for the year they were sustained using form TP-1012.A-V, Carry-Back of a Loss.
