if I were an imm officer, I would be confused to see totally new (fresh) forms, as I would presumably have original (or copies) of applications initially submitted to Nova Scotia. I read somewhere that we need to submit one copy that we made with our initial submission (for pre-26June applications) to the visa office.
should there be changes to the originally submitted applications whatever their nature is, I would make a cover letter and explain any differences to the original ones, to facilitate review.
