A recorded message stating that I had won a prize for being a "loyal Air Canada Jazz customer". This is the typical "prize pitch" scam where you must pay a fee or buy a product to get your prize. Well, surprise surprise! Once they have your info (i.e. credit card number), then you are up the creek without a paddle.
