I am adding Canonical tags to my pages, is this code correct ?

http://www.dating-asian-singles.com/

Code:
<link rel="canonical" href="http://www.dating-asian-singles.com/" />
http://www.dating-asian-singles.com/signup-stepone

Code:
<link rel="canonical" href="http://www.dating-asian-singles.com/signup-stepone" />
and so on, and so for each page ?

your help appreciated
