Canonical is derived from canon, which means: legitimate or official version - In the case of web site related terms this label is used to describe the correct url for a page. Many times with software driven websites, duplicate urls are created for the same content. So example a page may have serveral versions of the same content with can be sorted and displayed in different ways... Thus creating duplicate content. This term is also used to describe the proper url for domains (IE: WWW or NON-WWW). If your pages load successfully with both and you have not used the rel canonical to describe the correct url, then these pages all have duplicates as well.
