First off, the original poster "requested" that FFP's provide the information.
Secondly, my Aeroplan T's & C's state that the points "belong" to the "account holder". However, other T's & C's take away pretty much all rights associated with such belonging. Ownership of the card isn't stated in the agreement or on the card.
The only legislation I can see applying is (in Canada at least) either the federal Competition Act (regarding deceptive or misleading advertising) or the respective provincial trade practices act in Ontario whose laws are referenced in the Aeroplan agreement. The application here would be the inducement to purchase based upon a benefit (FFP) that can't be effectively utilized as advertised.
