Since NVC lost our file after IMBRA (and it's still not arrived in Montreal), we have to bring originals and copies of everything we've ever sent to or received from them, especially our two approval notices, and my fiancé has to come in with me to swear an oath (we think related to the IMBRA stuff).
Two weeks of getting conflicting answers from people and so much stress, but it all worked out for us, yay!!!
Good luck to everyone else waiting.
