My ECAS activated today after two days of receiving AOR.
For everyone's benefit I attach below explanation of RECEIVED and IN PROCESS status as per CIC.GC.ca:
Application Received:
Your application has been received at the Case Processing Centre in Sydney, Nova Scotia. Citizenship and Immigration Canada officials will review your application and the required documents and citizenship fees to ensure they meet the minimum processing requirements.
Application In Process
Your file has been sent to the Citizenship and Immigration Canada (CIC) office closest to your home for processing.
The CIC office will complete the necessary steps for a citizenship judge to make a decision on your application. If additional information or documents are needed, the CIC office will contact you.
If you are between the ages of 18 and 54, you will have to write the citizenship test. The citizenship test will determine if you meet the language and knowledge requirements for citizenship. You will be notified by mail about the time and place of your test. Once you receive your acknowledgment letter and the booklet called Discover Canada by mail, you should begin to study for the test. Applicants who are 55 years old or older and minors are not required to take the citizenship test.
An interview with a citizenship judge may also be required. Should this be necessary, you will be notified by mail about the time and place of your interview.
