Thank you engray!. Baby is born in Canada, So, as you said the child is Canadian by birth. My understanding is I should notify CIC that there is a dependent child now (Same way as we notify change in address or marital status etc.,). I would like to know how should I update this info in the existing application? or are you suggesting that there no need to notify CIC about the dependent child since the child is Canadian by birth??Is the baby born in Canada or abroad? If in Canada, then they Canadian and their birth certificate is their proof of citizenship.
