I don't have answer on your question, sorry. I am waiting for medical request from Ottawa and curious how your parents received medical forms, did Ottawa send the forms using your parents email or mail?
I have received SA few weeks ago and my application was transferred to Ofiice_ottawa but when I check Ecas I still have a status "Application Recieved on November 22 2017" there is no information about SA. is it ok?
I am very happy for people from the first round, for some of them the process was short and their parents already can immigrate!
Sad, that the second round people are still waiting for SA :(. Seems like nobody has received it yet.
Today I linked my application. I can see our application number and Date application received: 11/22/2017
but haven't received the official email with AOR. I guess it's ok.
