How do you know it is back focusing?  Have you done detailed tests on a tripod to confirm this?  If so and you are convinced that it is the lens, then you ought to send in the camera too, as it is the system that is giving you out of focus images.  No sense in Canon determining that the lens is fine if it is the camera that is out of specification.
