Canonical URL on frontpage

[EdmondHong87]

I have a site where the CMS system have added a canonical URL on my frontpage, pointing to a subpage on my site. Something like on my domain root.Google is still showing MyDomain.com as the result in the search engines which is good, but can't this approach hurt my ranking? I mean it's basically telling google that my frontpage content is located far down the hierarki, instead of my domain root, which of course have the most authority.
Something seems to indicate that this could very well be the case, as we lost several placements after moving to this new CMS system a few months ago.

Yes it can definitely hurt your rankings as it will give a signal to Google that the page is indeed somewhere else and for a homepage that is usually not the case. I would to try to get rid of the canonical URL if that indeed is the way to go.
