I am in the same situation, I sent renewal application in early January as it was running out in mid March. They did not like the photo and asked me to send in a new photo in February, that was sent in and the firearms site still had no indication that they had received the photo so I phoned in for an update, went through the entire IVR process to get to the correct area to be told via a recording they are too busy, to call back and the **** machine hung up on me. Tried it again on Monday and got through to a human after 40 minutes on hold, they got the photo and it is all in the "final stages" which, after a number of questions on my part is that it is with the Sr. Firearms Officer in my Province to do whatever they do in the process and they could not answer my question of how I could contact that person or when they would be done with the file. I was informed that I need to keep my firearms at home under lock and key until I heard from them about my "in the final stages" renewal application.
One thing I did find out was that my new RPAL if it is finally provided will be dated to the my next birthday plus 5 years as I explained that the way it looked to me was that they were charging me for a 5 year license but only giving me a partial amount of the 5 years.
Very nice folks on the phone but the system is almost as unworkable for them as it is for us, sad state of affairs in the Canadian Bureaucracy.
Be well.../B
