So I was talking to a few guys at Tims Shooting Academy and they said that this is happening more and more. They explained that the process is: sending in the appeal, receive response with the all clear along with the UPIN. Hopefully it’s that simple and quick.

Most people on the forums talking about going through the process were in the process for a while. Of course there are always exceptions and some people had cleared their denial and had a upin in a few months.
