Just now got a key from one of CIC employee:
Ecas update meaning:
Application received ..... When they check all yours doccuments and make checklist
We received yours medical on...."Date" .... Medical has be processed but they are still waiting for yours background, employement and security checks.
We started processing yours application.... Once they received all yours check they will send to VO for processing visa and Right of landing
Medical received.....If this is last line means you just wait for PPR everything is right in your favor.
Thanks for useful info. In my case, it only "Application received on Oct 28, 2010. Medical has been received".
As my understanding, my application is NOT yet processing? still in queue?
