Apparently if the VO requests documents from the person being sponsored, then you must mail them, but if you upload them those are only gonna be able to accessed by the office in Mississauga. Just today I was on the phone with the CIC and they said so.
I didn't know this until today but just thought I should post this here so everyone's aware.
If you're unsure, just to be in the safe zone.. mail them. Also upload the same documents.
