Guys...remember that the OCI and surrender rules have changed in the past 2 weeks....
You cannot submit OCI application and surrender application at the same time. You will have to wait for your surrender certificate to come in and then apply for OCI.
The weird part is that you also cannot apply for OCI for your child if minor and born in Canada until your surrender application is not completed. For eg. I lately became a Canadian and got my passport. I went to the BLS centre with my surrender application, OCI application and also my son's OCI application who is 4 months old, my wife is Indian. BLS refused to file OCI application for me AND my child as well. They said that we can only file OCI for yourself and your child when I receive my surrender acknowledgement.
So long story short; if you have taken your oath and have a new born with plans to travel to India, DO NOT apply for Canadian passport. Go to BLS with your and your spouse's Indian Passport and file for OCI for your child based on your Indian passport. Indian Passport can be used 3 months from the date of your oath btw.
Once your child's OCI is accepted, go ahead and apply for Canadian passport.
