@George_S2May 16.2013 — #Canonical url is most important part of seo, every website require to canonical url reference for search engine, If this reference is not available than after sometime you will face the problem of duplicate content like www. & without www. domain name is consider as a different domain name for search engine.
@Steve_SmithJun 06.2013 — #When a page of your website is being opened with multiple urls so it would be considered a canonical issue and Google rates it like a Duplication.
