Cut from that article:
"Police are reviewing thousands of gun ownership files to determine which weapons have lapsed registrations and which are now banned, he said."
This is the full problem with the idea of any registration. Once the Government knows who you are, all they have to do is go down the list, and knock on every registered gun owners door. At that point, you will have one of two choices, die as a free man, or live as a slave. It is a direction that we should never have to even think about. I like the way the last Pres. of the NRA put it. You can have my gun, when you take it from my dead hands. Canada, shame on you!
