I have a similar type question but no reply. If I am not supposed to post here and should start a new thread, my apologies and please tell me. I had one Aeroplan rep who was nice to answer my queries but the second time I called a different rep refused to spend time because I was not booking. I can't book if I don't know what I am or am not allowed!

Business class on Aeroplan allows 2 stopovers AND (not "OR" I think) one open-jaw. I presume destination city does not count as one of these 3, correct? So, is this route valid?

YVR-LHR (stopover) - AMS (stopover) - ZRH (destination) - FCO (open jaw) - YVR (home)

Is there a restriction in terms of direction?- I read somewhere you can only fly east to west or north to south but not both or backtrack.

And do you have to do the whole trip with one airline only?
The rep also mentioned something about having to calculate the total miles to determine what is acceptable or not. How do I do this? Thank you for your help.
