Initially it will be in CPC Ottawa office. There is no particular time when the file moves to other VO. It may or may not move. My suggestion is there is no use knowing VO. Sit back ,relax and wait patiently for the golden email.o
Oh ok thank you , saw couple of posts like this, where people were able to get their V.O details through email
