Update:

I just received an email from CPC-CTD-Ottawa saying that my documents will be returned to me on Aug 22 via Canada posting with tracking number xxxxx

Here is my timeline:
Passport delivered: Jul 25
Application approved on CIC profile: Aug 21
Email notification for return package: Aug 22 (even though my tracker hasn't been activated yet)

Tracker activated at 17:25
 
Anyone knows how long it takes for the tracker activation after approval ? I saw someone got approved last week and just have the tracker activated today.
 
Day 26 since passport delivery ....

No updates yet ... keeping my anxious fingers crossed ....

In my case, I called CIC last Friday Aug 18th to check status. I was told that my application was approved on Aug 17th. Then yesterday Aug 21, my application status was changed to "Approved" and today tracker was activated.

I am not sure if everyone would receive an email from CIC indicating that documents were sent back. Feel like it was because I had an "inquiry" about my application on the phone and thus they replied me back as a standard procedure?
