Air Canada passenger gives birth to girl on flight to Japan

So the plane was not crowded enough, now they have one more passenger onboard!

So now comes the obvious question. Obviously the baby girl's nationality is Canadian. But what would be listed as the place of birth?

As a woman I am always shocked that a woman doesn't know she is pregnant. It happens but I truly don't get it. My understanding is because the flight originated in Canada that makes the child Canadian. Not a nice place for the mother to give birth with everyone hearing everything and so many things could have gone wrong. Thankfully mom and baby are fine albeit surprised.
