I just booked a one way BOS-YYZ ticket today on MP for 12,500 miles + $2.50. Debating whether to cancel and rebook on AE on Jan 1 for 7,500 miles + $60.
Aeroplan has a form you can send in and say something like "I think you should let dDiamond members cancel or change for free like United does."
I got a pretty personal response to that, and they said they appreciate the feedback and would look into it, for whatever that's worth.
