The IRCC can read the notes written by the officer, he wouldn't say it is granted if there is no note stating that. However, to be a citizen, you have to take the oath.
Congrats! I have 3 questions :
1. What is the date of your oath?
2. Could you please share the email address that send you the oath invitation?
3. Did you send UP request to the office that sent you test invitation? Or using a web form?
