@darkproc you are right about the last question to link the application.
1.Received by CIC on April 29th.
2. Ecas updated today, the status is "application received on April 29th".
3. Today linked the application to my account on canada.ca and got the application number and the status is " We are processing your application. We will send you a message when there is an update or if we need more information from you."
The trick is the last question that how many family members on the application. In my case: me , spouse ,one kid, father and mother. When I filled 2 or 5 then get nothing. I filled 3 to link the application finally.
Good luck!
