It's not clear what you're asking here... are you asking what would happen to the status pass if you cancel the entire trip ? The answer to this is, yes, it will be returned to your account, but you should call in (to Aeroplan) and have it removed before cancellation if you are unable to do so on the website. It could take them a while if you need to have it reclaimed after the booking is cancelled (I had to do this last year for a friend who cancelled and made a new booking without telling me...)
