That's interesting. I didn't realize it would change. I had my medical exam done on September 17th and my online checker thing still just has "We received your application for PR on December 3, 2012."
Prepare to speak about banal topics as if you have a real interest in them. Totally disinterested in sports? Prepare to speak about sports in your home country as if you go to sporting events at every opportunity. Your ability to disguise your contempt for the absurd topics will count in your score.
I don't really have the time to keep the spreadsheet updated, sorry.
My noc code is 2171 (Systems Analyst). Someone asked about the online status at CIC.gc.ca and it's still "Application Received". I don't know why I can't reply by pm.
I can give another data point.
My PR application was received December 3, 2012. I received my medical request yesterday (August 21, 2013).
They're still working, just slowly.
