Here's my story:
CPC received my application: October 30, 2008
They sent me letter of acknowledment & A look at canada book : October 30, 2008
They started processing application: May 14, 2009
Application was transferred tp Edmonton office: August 31, 2009
Notice tto take the test: Sept 11, 2009
Took the test: Sept 25,2009
I couldn't find my expired passport at that time so they gave me a questionnaire to be submitted within a month. And I did found my expired passport, photocopied it and submitted it with other documents indicated on that qustionnaire.
Until now I haven't received the oath taking schedule, I called them yesterday and was told that if I haven't received the schedule by March 25, I have to call them again. They did received the questionnaire October 15, 2009. And I am pretty sure I did passed the test. I am not sure what's taking so long. All in all, it's been over 16 months from the time they've received my application...Hopefully, I won't be waiting much longer...
