Since this page is linked more than once on the Homepage and other high traffic pages, we found it logical to add a reference parameter at the end of the URL.
Logic is a means, not an end. (Everyone gets this wrong.) What purpose were you trying to achieve?
Along with the "rel=canonical", you can go to GWT and tell them to disregard the "ref" parameter.
