Superficial loss rules - overriding T5008 capital loss

[rejjie]

I have superficial losses which unfortunately means I'm unable to claim the capital loss on the Schedule 3 form.  However Ufile is importing my T5008 forms and automatically claiming the capital loss.  How can I override that capital loss to make it zero ?

In the Interview Setup, down the left hand side, tick off the box in the Investment Income and Expenses section that says Capital Gains (or losses) and that should bring up the specific entries for each of your T5008 auto fill lines. Find the line entry that is the one in question and change the Acquisition Price to a value that zeroes out the capital gain.

I never use auto-fill for my T5008 data. I don't trust it, especially Box 20 Cost Data and for USD investments, it will get it wrong all the time.  The forex used on date of acquisition of the security cannot possibly be the same as the forex in effect for the Sale of the security, except by sheer coincidence.
