Air Canada is 4*. We are the best, rah rah, our partnership with Aeroplan is complex, so just don't worry about it, when things go right, it's because AC is the best, any complaints, it's because Aeroplan is separate so it's their fault.
Now, distinction.... Ah crap... Even we don't know about that crap, but it sounded fancy....
Call us if u have more questions. We'll answer in about 90 minutes, because you are not altitudey enough, even though you may be distinct.
