Same Exact thing happen to me. They ask me to renew my child passport (For PR Application) who is not accepted as refuge because he is from safe country (USA) but my entire family got a Protected Person status. So I did all my effort to get the expired passport with no result. I talked to CIC they told me sense you did all your can do, you do don't have to. however you have to prove that you cant. so i sent all the letters i sent to CBSA and CIC and their responds. I talked to to CIC three month later they told me everything is OK and I don't need to worry. Good Luck and don't panic.
