Hi, I'm not express entry, I was nominated through SINP and could only apply paper based...
One point in favor was that I had medicals expiring in August and I sent the application before that, so at the beginning in ecas showed medicals received but after that I received the mail to re do the medicals.
And my case I believe is pretty straight forward no kids yet, only my wife and I always lived in my country before coming to canada.
But until not getting the golden mail nothing is written.
Good luck mate.
