Hey! Can you tell us a little bit more about this "fairness letter"? I've never heard of. Before ever "negative decision" people always get this letter? Do you know any examples of people being denied? tks!
basically, it's an email stating that the officer has reviewed the docs and is not satisfied with whatever it is people screw up with the application: accidental misrepresentation, insufficient cohabitation proof and so on. then it states that the applicant has 30 days to address the concern(s). otherwise the app will 100% be rejected. if you haven't received anything of this sort then the decision is positive. ircc won't deny an application without giving an opportunity to address officer's concerns.
i've seen some examples on the forum (if you're curious, look for "fairness letter" through the forum search and you'll see a couple of threads where people share their experience with that). depending on what the concern is, the denial is possible. i've seen people who have forgotten to declare previous visa denials from other countries and that was considered misrepresentation. however as soon as they wrote a letter to the officer explaining that they were not hiding anything and it was a simple mistake, in a matter of a couple of days they'd get a positive decision.
anyway, you've got nothing to worry about as you haven't received anything like what i just described. just wanted to elaborate on the whole "fairness letter" thing.
