Just back from my CAA travel office (Brossard, Qc). They do sell the tickets with the 25% off (and not only as part of a package so I guess the offices work differently from one another) and they are actual plastic cards but, and this is a big but, they are not the "regular" tickets, they are identified as Canadian tickets. You can add them into
MDE and make FP+ ressies with them but you need to exchange them for "real" tickets at Guest Services once you get to WDW. You still get the discount on the tickets and you buy them in CAN$ (they sell them in U$ but they do the conversion on the daily rate and that's what they charge you so no additional fees from the credit card company) but no one knows if these can be bridged if you want to upgrade to an AP and that's the heart of the question right there...
The employees at the CAA office tell me they are selling tickets directly from Disney but I still think they are considered as a reseller. Robo might have the answer, I'll ask him on the Theme Park board.
I didn't buy mine right away as I still need to think things through.
I'm not going until March so I have time before the promo expires but I'm afraid of a price increase in the next few weeks. I guess I'll just wait and hope we get at least a couple of days warning ahead of time so I can buy them before the raise if there is one.
First world problem, I know...
