The canonical url was pretty much designed for websites that initially had alot of semi-duplicate content pages. A webshop for example that sells 5x the same product, with the only difference the color (in white, black, gray etc). This could cause confusion and it's best practice to use it.

I deploy it these days on all websites; i dont see alot gain from it really, as MOZ is a indicator on what should be improved technical wise on your website. But it dont hurt either.
