When you say first process do you mean CIO-Nova Scotia, and second process the Visa Office?
If you are just submitting to CIO-NS, then no need to send the proof of funds documentation yet. You do, however, write the amount of your funds in the forms.
If you are submitting to the Visa Office after you have received the 1st AOR from CIO-NS, then you have to follow the visa-specific office checklist on the documents you need to send (and obviously, need to include the proof of funds at this point).
Hope this helps!
