ECAS stands from Electronic Client Application Status. This on-line service allows Citizenship and Immigration Canada (CIC) clients to view securely the status of their immigration and/or citizenship application(s) on-line, 24 hours a day, 7 days a week; anytime, anywhere.I'm reading few times the word "ECAS", what is that? I sent the application and was received on October 01 st, and no news from them since.
