I operate this route year-round and while I've been known to be wrong I don't see either scenario happening (being Rouged or Cancelled). Upon the start up of Rouge I would have predicted that YYZ-AMS would have been one of the very first assigned ACR routes. Not so. By all accounts the route is doing well against the stronghold that KL has at AMS. My last rotation on the A330 - 100% and 99% load factors respectively.

Look at MAD. Short seasonal window of operation. Non-Rouged and this year upgauged to 787 daily. You never know.
