My suggestion is to send a new form since this is a bit vital info...
U can send it the form right now to CIC...attach a cover letter stating that ur name has not mistakenly provided ...
State ur name+DOB+PP number+UCI (if any)+NOC code+ Date of rcvd...
Also email them to below ID (write "URGENT" on the subject of the email)

Consider the above without space.
Please include below info on the email body:
Put ur Passport Number
