Congrats, Natasha! I would wait and see, keep checking emails and then call CIC either tomorrow or Thursday and ask about it if you don't receive and email by then.
JohnnyP, I do believe that you and your wife would have a difference UCI as she is considered a client by herself if she is the sponsor. Call CIC to get her UCI as my husband and I have different UCIs.
This is the page that I go to when I want to look at my status:
https://services3.cic.gc.ca/ecas/authenticate.do?app=ecas
You should be selecting Client ID Number/Unique Client Identifier under the drop down menu, entering the UCI without the dash in the middle so, like this ******** and not like ****-****. You should be entering your surname as well, your birth date (in this format yyyy-mm-dd) and then your country of birth. If it is not working, contact CIC to tell them that you cannot access your status. I logged into my application status without issue.
