One other proof that the application has been received at Mississauga is the tracking report provided by the courier firm. DHL, for example, updates the whereabouts of the application at every step, as it wends it way to Mississauga). Given the consequence of error, I want to be able to prove to DHL (or CIC for that matter) where the aplicaiton was at last report. Once the application arrives at Mississauga, I will print the "arrival at destination" report, save it to hard drive, and have it in case of "loss" or misplacement.
