I was sure that I had kept the old one for my first centerfire pistol, which was a 4" barrel Ruger GP100 that got me into the 12.6 category. Just went through all my gun paperwork and could not find it. Disappointing.
Interesting story, a Cop in Ontario was charged with possession of an unregistered restricted weapon shortly after they set up the new system. He had put a pistol on consignment in a gun shop and when they went to do the transfer it came up as "not previously registered". His own people arrested him and he was suspended pending trial. A year later, the trial starts and some CFO testifies "the computer says it's not registered".
Defense says "did you bother looking for the original paperwork at the office of the police service that originally registered the firearm?" (same police service doing the arresting).
CFO - "No".
Defense - "Why not?"
CFO - "The computer is always right"
Defense - "Well let's look, shall we?"
A twenty minute adjournment to go to the old firearms office and bring the old firearms log books down.
Defense - "It says right here that so-and-so brought in the pistol to be registered on such-and-such a date and two months later the registration certificate came back from Ottawa and he came down and took possession of the pistol and certificate, and the certificate number is #######. Search for that on your computer, please."
CFO - "Ooops. Found it. Sorry about that. Uhhh, I guess we should move to acquit?"
Defense - "That would be a good idea. Your honour?"
Acquitted.
Scenes like that played out in courtrooms across the country for a few years until it was established that information from the firearms registry is not reliable enough to be permitted as evidence in a court of law, which is why you never hear about the gun registry being used to solve crimes.
