I have not heard of them. Is your application at your visa office already? If not, it should be at Mississauga still [I think] and you can do it via a webform on their website. I would go that route personally.Thanks a lot , I saw others experiencing the same situation , and some said they mailed it to CPC-Mississauga , since there are different offices with different postal codes , have you heard about any specific office called as ''Required Documents ''? with the postal code of L5A4H4 ? or should I just send it to the office that I've already sent the application ? (which has a different postal code). I try to call and ask but not been yet successful.
