Canonical is needed when different people look for the same goods using different search methods. For example, Person 1 is looking for a new pair of shoes by choosing the needed brand or model. At the same time, Person 2 can find the same shoes via setting a particular price or using the rating. Both of them enter pages with the same content, but, actually, their URLs are different.
To solve it, just choose one main page and refer all the other ones to it by tagging them with the canonical attribute.
This situation is also about online-shops. When you have a particular number of the same goods differing only by a color. It is better to choose one of them as the canonical and bind other ones to it.
