I know thread is on TPAC flights, but I just searching for a flight from YYZ to CPH for March Break and found no Tango fare listed. I click the "show me the upgrade" box and selected the direct flights and the total come to $1336.77. I do not watch the price for this route all the time, but kind of recall it is about the price that I used to look at, maybe $100 more or so. Maybe AC decided to pull back the whole Tango fare and go back to Tango Plus afterall? (yes, I know it is a dream) If I remember correctly Tango / 50% had happened in the past (4 or 5 years ago) for TATL flights and then they removed it and only re-introduce a few montsh ago. Hope someone from AC did finally realized the whole Tango fare for TATL / TPAC is really not going to work.

played with the starting city and found starting at SYR is when I see Tango Fare (T Class) and the total for SYR-YYZ-CPH rt is CAD$859.71 ai. Then I click the "show me the upgrade" box and select the exact same flights that now book in Tango Plus Fare (S Class) and the total if still only CAD$960.71 ai. So Tango vs. Tango Plus is only CAD$61!
