How to find canonical errors ? ? ?

I'm not much sure about canonical errors but yes I would like to know more about canonical errors. Well I think canonical errors can be find out to Google Webmaster Tool.

Canonical errors are two type first is canonical tag and canonicalization.

Canonical tag: Many web site has same product display on their different page, by adding canonical tag we tell Google about the original page of that product.

Canonicalization: Here we transfer our site from non www to www if any user is searching our site without typing non www. Then this will help the user to land on our homepage.

Canonical actually isn't not an actual error, but this particular tag defines that the content on the page is taken from other URL. When a search engine spiders crawls your canonicalize URL, it will redirect spiders to that URL.

thanks for the answers and nice tips here
