hirenkarishma as nerver-wracking as this process is you really need to relax and be positive. We are all in the same boat here waiting for news

Processing times in ND are very fast. You and I sent and got approved around the same time in Mississauga and at least you got a change in your ecas to show that it is in process! I still haven't had anything which is the norm for this visa office... ND is very fast and if you feel secure in your application you have nothing to worry about. I've seen most ND cases finishing after 90-120 days. You won't receive an AOR but if they need additional documents they may request them or they will just request your passport. If there is a chance for an interview they do send a telegram first then the letter.
Take care and be patient!
