She did not apply for your citizenship, since you are already a Canadian citizen.

When you communicate with CIC officials in the future you should not say that you "became" or "took" your Canadian citizenship recently. That's not accurate. You were already a Canadian citizen, even if you didn't know it. You should say that you applied for your proof of citizenship relatively recently and had not previously realized that you were a Canadian citizen. It's important to be as accurate as possible in order to maintain your credibility when dealing with CIC. You also shouldn't say that your parents were not Canadians since they were Canadian citizens (through naturalization).
Unless you are a minor, you must have signed the document. In the future I encourage you to make sure you understand what you're signing since you are legally responsible for it.ı have sıgned absolutely nothıng because she dıd all..ı was not even ın Greece when she dıd the procedure...she went to the embassy there and she got help from there,thats all ı know
