In Process ECAS: Sep 15, 2020
- We received your application for Canadian citizenship (grant of citizenship) on March 23, 2020.
- We sent you correspondence acknowledging receipt of your application(s), and a study book called Discover Canada on September 15, 2020.
It is not in 'In Process' yet. When you login to ECAS, the main landing page shows the actual application status under title "Citizenship Application Status".
With above two lines, I guess it would be 'Application Received' for you.
