Is having a canonical tag for the link that IS the canonical a negative thing?

[kbbseo]

Throughout our site, canonical tags have been added where needed. However, the canonical tags are also included for the canonical itself. For example, for www.askaquestion.com, the canonical tag has been added as www.askaquestion.com.

Will this have a negative impact or does it not really matter whether there is such a loop?

I don't think ti is bad but actually encouraged. Ever copy of your content should have the same canonical tag. Obviously that includes the original. As I understand it, this is something you should be doing.
