confusion, new delhi visa office checklist questions

[formalboygirl]

hi please bear with me, I have some questions;;;

in the document checklist from new delhi visa office for spouse sponsor.. they are asking...

1) identity and civil status:--
what do we need to send here, birth certificates? isn't passport or national identity certificate enough?

2) children's information:--
is this for a child going to canada or if I don't sponsor child now is it still required?

thanks
