I had my test on 19-Mar at St Clair office. After writing the test, I was told to wait for an interview. I had to wait for about 45 min. Then an officer called my name. The interview was basically for checking identity and knowledge of English. After greeting, the officer told me that I had passed my test. Then I showed (1) PR card, (2) Landing Paper, (3) Driver's Licence, (4) Health Card, and (5) Passport. The officer checked these documents against the photocopies in the file. She went through the passport but did not check each and every stamp. Then she asked me a few simple questions about my occupation and family. It was over in about 10 min. After that she told me that a citizenship judge will make a decision about my application and that I may hear from CIC in about 2-4 weeks.
Here is my timeline.

CIC started processing Dec 2012
Test taken Mar 2014
