You can only bring the child if he's becoming a canadian along with you. And if you do so, you'll need to invite an adult to the ceremony in all cases : you can't leave the ceremony room at any moment, the person you invite would then take care of the child. Same if he's not becoming canadian... He would then sit with that adult first place
Oh, and regarding the link by
@foodie69, kinda infortunate, but nothing else. If you think you'd like to have your son or daughter with you, do so. It's a special day to you and you want to share it with your loved ones. Your child is the dearest person to you... Actually, some baby made (small) noise at my ceremony. Didn't bother anyone
