In my opinion canonical URLs are used to avoid the problem of Duplicate content.
It is the URl that you want visitors to see.Canonical URL is the simplest and most significant/authoritative version of the URL.

As per my knowledge,Canonical URL is the search engine friendly URL that you want the search engines to treat as authoritative. In other words, a canonical URL is the URL that you want visitors to see.Quite often canonical URLs were used to describe the homepage.

Search engine identify your main url with http or http://www that is very important factor for improving search engine ranking or avoid duplication.
