Canonical issue arises when you are posting the same content in more than one site.So, if you are doing like this then you need to mention this in the header file.Otherwise Google can penalize you considering your content as duplicate content which is a black hat method.

Google can reach to your web page through different URLs, this may create a confusion of duplicate content for search engine. To avoid this, we choose a preferred path for the web page or say canonical path for the web page.
If you donít set a preferred path this may raise canonical issues.
Canonicalization is the process of picking the best URL when there are multiple choices available. Typically a search engine, such as Google will attempt to pick the best URL that they feel is the authority for that page. rel="canonical": Place a link of the form <link rel="canonical" href="http://***.com/canonical-url-***.html"> at the end of the <head> of each duplicate page

As per user all these URLs are same but google consider all these pages as different pages with same content and it can cause duplicate content issue it is called canonical issue

It is helpful to solve duplicate content issues because two of your own url has same content well you know that, those two url is your and you put the same content in it but Google count it as a duplicate content at that time canonical tag is useful to you.
Infect URL with www and without www Google consider it as a two different URL so in those two URL content duplication occur so canonical can resolve this issue

This is what Matt Cutts said about Canonicalization way back in January 4, 2006:
It is now extended to inner pages also, as you can see from the following link google.com/support/webmasters/bin/answer.py?answer=139066 about Canonicalization. This link has the explanation and solutions to deal with canonical issues.

Yes it does matter a lot for the large shopping portal which consists of various types of products and its refining factors, canonical is the only way to prevent duplication from those refining factors. you have to specify canonical to the all duplicate pages of original one in head section.

Say you have a main website and 2 mirrors of it with the same content. For a concrete example, let us assume your main website has an article at : http://example-main.com/foo.html
And the other two websites have the same article at http://example-2.com/bar.html and http://example-3.com/baz.html.
In all the three HTML pages, you should place this tag in the <head> element.
This will tell the search engines that it should use the main website while displaying results when somebody is searching for content that is present in these pages.
<link rel="canonical" href="http://example-main.com/foo.html">
This helps both the search engine as well as yourself. Search engines don't have to crawl the duplicate pages and waste its computational resources in de-dup. Your main website gets better page rank because any backlinks to the duplicates contribute to the score of your main website. You also get more traffic to your main website because that's what comes up in the search results.

Canonical Definition: If the same page (NOT CONTENT) is being rendered by more than one URL, it is called CANONICALIZATION.
The possible canonical URL of 1 Domain could be 3
Impact on SEO:
1: Since the same content is being rendered by the 3 more URLs, Googlebot (specially, as it always says and hates duplicate content) thinks that your website has DUPLICATE CONTENT, hence the less trustworthy.
2: The Link building campaign could be less effective as sometimes you pick www and sometimes non-www and sometimes domain/indexpage, by this way you are going to distribute your PR advantage to 4 different URLs.
Solutions: The best method is to use 301 redirect for rest 3 of the URLs to 1 URL, by this way you will gain all the Back link advanges to improve your PR.
Use of rel="canonical" tag in head section of your page
