I am SINP inland applicant with 3 dependents.When it changes to Application received on ECAS it means your file has been transferred from Sydney or Ottawa to the local office in the city where you live. My friend got the same notification on ECAS and when she called was informed her file was transferred to the Calgary office where she lives.
Are you a single applicant or do you have other dependants on your application? Not sure how they decide which applications get transferred to the local office.
