Mentioned briefly as only a rumor on the Air Canada Aeroplan forum, my wife and I this afternoon asked the cashier at our nearby Shoppers Drug Mart if they were no longer accepting American Express (Canada) credit cards at their location. She confirmed that after December 1, 2012, SDM will no longer accept AMEX for purchases.
Just a heads up, for those of us who use this large drugstore chain up here.
