With your Itinerary posted above, you can add DUS as a stop.
For your return, you could also come back via Europe.
For example:
HKG - FRA - ZRH - YUL - YYZ
I thought it was one stop in each direction, so you couldn't have both ZRH and DUS as stops en route to your destination in Asia? Am I mistaken?
