Hi, i havent changed my address but when i got my SIN i was at my cousin's place so i used that address for my SIN number. I live somewhere else right now

so what would be my address here in this address window where i input " care of" and things like that. And also what would be my answer to "Did you change your mailing address?" Yes or no

If you can still get mail that's sent to your cousin's place, then you can put their address. You don't need to put anything in the "Care of" box. And you would say "No" to "Did you change your mailing address?".

But, at some point you should let the CRA know your current address.
