Hello dangerdays ,
I need to ask you few questions before giving you answer to your question. Like Have you submitted your passport along your application ? Where did you applied ? Did you applied online ? What type of visa you applied for ? Its really strange thing I am sure you have not submitted your passport yet because in the step that you are now CIC do not ask for the passport but after medical and all application procedure. Anyway I think that can be system generated error and that email sent to you by mistake. You can ask them by writing them (CIC) email.
Thanks,
Sonu Ahmad
