From where did you apply, What is the status written on your online linked application account in "Final Decision" Column. I think your visa is stamped and you will get it within couple of days as when your documents return back to your local VFS in your city, but don't ignore the pdf from CIC as they may be some kind of error but still they are corresponding with your application on your account, If I remember correctly didn't your medical already pass on your online account. Usually the people who apply online get the passport submission request through pdf after application approval, As you already passed medical after getting medical request, they should not send you the medical request again. I think you will get your passport back in some days with visa stamped. Good Luck, Hope for the best.
