CP. My quick research hasn't turned up a result. I'm working on getting a more detailed list, but so far, I don't have that one. Whoever had that booking with the CP tax, if you wouldn't mind either posting or sending me a PM to let me know what it was (there should be a description on your Aeroplan booking confirmation), it would be appreciated

CP is the IATA code for a change fee (usually from GDS bookings). If you're able to see the amount corresponding to CP and the ticket stock on that booking, it should match up with the change fee for the ticketing airline.
