i don't want to give u high hopes but i'm almost sure that u passed stage 1
maybe the sponsor approval letter is on its way or even worse it got stuck like the canadiangirl's one :
once we got the sponsor approval email the ecas was not working at all; after a few days they had the "we received ur pr application on this date" under the PR application tab; and a few days after that there was "medical results have been received message" too which for me it meant almost 100% sure that the file already reached the vo (since the medical results r with the vo not with missisauga); actually from what i know they transfer online the most imp forms and the rest (relationship proofs) will go with the phisical file and take around 2 weeks to reach
so yeah it looks that ur fist stage is done, all u need to do is call and confirm that; good luck!!
