It's not my place to comment on where the government wants to go. My place is to do as I'm told when they decide where they want to go, and that I will do.
As far as the information in the system goes, the amnesty is there, but the old information is still there as well. The dates on a current licence or registration may be an issue. The government must decide what they want to do about it and then tell us what their wishes are in that regard.
I'd also point out that the Canada Firearms Centre is more than just a registry. It's a program that involves training and education on the safe use and custody of firearms. It deals with the storage of firearms. There are a lot of pieces to this program that provide an ongoing benefit.
