Hi
1. If you can prove blood relation with your cousin, off course you should declare. U can claim 5 points for relationship. Secondly your cousin shall be existing resident of Canada. Mere citizenship and living in any other part of world will not work. Person should be living permanently in canada at the time of application
Visit CIC website and assess your self online.
2. If you can not get any document from your past employer for any reason, submit appointment letter along with explanation letter for reasons of not attaching experience document
