Debt forgiveness anti-avoidance rule

I came across an interesting (older) technical interpretation a few days ago while looking at another matter. In TI 2009-0338911E5, the CRA commented on the rules in section 80 of the Income Tax Act applicable to a CCPC that was winding-up voluntarily where, as a result of the winding-up, debt owed in equal amounts to the 50/50 shareholders of the corporation would be forgiven.
