Thank you for the info. Mine shows application received.ECAS stands for Electronic Client Application Status.
Here's the link to check yours:
https://services3.cic.gc.ca/ecas/authenticate.do?app=
As you already received your AOR email, it would be a good time to check it. You would need your Client ID (or some other options given in there), your last name, date of birth and place of birth.
It will show you the stages - Application Received, Under processing, Decision Made, etc.
