Relax, take a deep breath, and Relax.
As long as you used courier, it's been received, no CIC Office acknowledges anything received via hardcopy, some VOs specifically tell you to use a form of delivery that you can track, even CPC at Mississauga just started the text message option to confirm if they received initial application packages.
You have done your part, check tenders posts to see how long she waited, give or take three to six weeks, so now is the time to practice your faith, keep waiting on God, and believing for speedy and positive response.
It's hard, but it has left your hands, AVO would not respond to your enquiries for now, all you should be expecting now is medical and PPR.
I wish you all of God's best and mercies.
