I understand now. It's a difficult position to be in. I don't think it is likely that IRCC will grant an extension to your passport request. More likely, they will tell you to sponsor the child when the child is born. Please update us on the forum as to what happens in your case.We havent sent our passports right now. We received the mail 3 days ago and have replied saying that we wish for an extension and have informed the change in circumstances again. The deadline for sending passports is 30 days.
We want the child to be born here in India and not travel right now to Canada. Getting a job there and the expenses for the delivery etc in such short notice would also be a pain.
I wish if they can give us an extension so that we can include the child once he/she is born and travel together.
By the way, delivery expenses in Canada are covered by the provincial health plan, so your out-of-pocket expense is $0.
