The cdn Amex platinum (not the aeroplan) comes with the upgraded priority pass that has no usage charges for you and 1 guest, unlimited use and can be used at lounges in the US that don't accept credit card issued priority pass.

You also get one world status high enough for their lounges, and bunch of other airline lounges as well as hotel status with SPG, Carlson, Accor etc.

But it is an expensive card.
