Right now I doubt that there are any such plans, but in the long term I am sure that they will want to start a fligth like that. I'm sure after the merger is finished there will be a large number of new route/aircraft announcements. Although PIA already has an almost daily flight to YYZ with the 747, so maybe AC will choose to have YUL flights.
