You case is very similar to mine. So, I will give my inputs.
I sent my passport on Sep 18 from Chicago, delivered on Sep 19, received acceptance email from CPC - Ottawa (After my inquiry) on Sep 21. Received alert from CIC on Oct 2. Same as you not message, application updated to approved. received response from CPC - Ottawa on Oct 3 that passport has been dispatched (after inquiry, they do not send e-mail if you don't ask). FedEx took 3 days to activate tracker. received passports on Oct 7. So, don't worry, it should all work out.
A couple of questions for you:
- what state and city did you ask fedex to deliver passport to
- what shipping type you used (international priority, or international ground)
