You can:
1. Withdraw profile.
2. De-activate job bank assigned to the EE profile withdrawn - this is requested in the confirmation letter you get after withdraw your profile. The option to deactivate is available within job bank.
3. Lodge a new profile.
4. Once lodged, a confirmation letter is issued again asking you to complete job bank registration - next steps. Your status will read PENDING ADDITIONAL CRITERIA
5. Register with job bank following the instructions and new code in the confirmation letter. THE CODE is important as it verifies your registration and connects your EE profile updating your STATUS. I do not know what other members have done here, but instead of creating a new JOB BANK profile (as that is a painful process in itself) you should be able to:
Login to Job Bank
Go to MY USER ACCOUNT
Go to UPDATE EXPRESS ENTRY INFORMATION
Enter details
Accept terms, click on CONTINUE
6. After registration with job bank, your job bank account should show "active/live"
7. Wait 24-48 hours for status to update to OPEN in EE profile.
