Hi I have searched forums and can't seem to find the answer I am looking for so any help would be appreciated! I am in the process of sorting the application for my daughters Canadian passport (born in UK with Canadian father) so we are filling in the proof of citizenship form first. My questions are can we apply for the passport and proof of citizenship at the same time in the same envelope and which office do we send the applications to. I find it very confusing on the web as it is not clear if it is London or Canada. Thanks

For citizenship send to the following

I have a feeling you would need that certificate in order to apply for the passport so you would need to wait for that to come back first anyway, is that right, FL?
