I am in the second phase and have to submit full documents to New Delhi.
I will like to know, do i attach photocopy of the forms sent to NS or should i fill the content again in a separate form and send it to New Delhi.
You need original forms and not photocopies. I am pasting below the text from "Instruction Guide [IMM EG7000]" Pagee 22.
For your personal records, you should retain copies of all forms. Each copy must have an original signature. You will be requested to submit a signed copy of these forms if the application is recommended for further assessment to a Canadian Visa Office. Should there be any changes made to the information on the forms, a letter of explanation should accompany the submission to the Visa Office.
