I am in Canada and I just want to know the procedure for change adress for CITIZENSHIP of Canada application.

We need to know where you are in the process. If you have your AOR you can probably login and change it. If not your best bet is probably just doing a Canada Post redirect but then of course your form won’t list the latest address...
 
If you HAVE received AOR, you should be able to log into ECAS and change, or call the call centre and ask them to change for you.
If you have NOT received it, they will not have your application in the system yet. You have to wait until you get AOR, then log into ECAS and change, or call them and ask them to change it for you.
