Am thinking of flying with AC CDG/YYZ/CDG, paying Y and upgrading to C with MP miles.

Can someone tell me in a few words (if this possible ) what the procedure is? Can this be done on-line? I have had a look at AC website, but found only info on upgrading with certificates or Aeroplan miles.

Thank you!
