Ah, there's the rub! Just checked on both the Canada and Belgium Apple Stores and found that in Canada you get two keyboard choices, English or French (both extended QUERTY), whereas in Belgium you get four, Belgian (AZERTY), Swiss (extended QUERTY+special symbols), International English or standard US English.
I think you are going to get an extended QUERTY French Canadian keyboard. If the keyboard is the only customization you ordered, I think you can return it for full refund if the box is unopened. And the only way to get an AZERTY keyboard will be by ordering from an EU French-speaking country.
