This is the reply I got today from The registry:
"Yes, you can renew your firearms licence, please provide me with your full name, firearms licence number and your complete mailing address and a renewal package will be sent to you. Note, the form CAFC 979 can also be downloaded from our website at http://www.cfc-cafc.gc.ca.
If you have further questions, please contact our office at 1 800 731-4000.(end quote)
Since all it will cost is a photo, I will renew mine anyway, it will give me a couple of extra free years. I encourage ALL to do the same, you save, and The registry doesn't get your money(the most important)
