First of all I would like to point out that Canada has not used FACs for years. To own, and purchase firearms you need a PAL (Possession and Acquisition License). These come in two varieties restricted PALs and unrestricted PALs. A restricted PAL allows the owner to own Handguns, and other firearms deemed as "bad" by previous Liberal governments. Although we have had a registration system in place for handguns since the 40's we recently had a long gun registry system put in place, which requires us to register everything from shotguns to bolt action .22s.
Although the government that put it in place swore up and down that this was not a pre-cursor to a ban of all firearms, that same party has recently stated it's intention to ban all semi-automatic firearms restricted or otherwise. And they have a handy database at their finger tips to help them with this process.
Proponents of gun control need to look no further then the UK for the biggest example of the complete and utter failure of gun control. Gun crimes in the UK have gone up astronomically since they banned pretty well all firearm ownership. When you ban private ownership of firearms the only people who have them are criminals. One thing that people don't seem to understand is criminals by definition don't follow laws.
In Canada we have seen our firearm privileges slowly eroded by politician's feel good solutions to complex problems. I have no doubt that in the next decade all private firearm ownership in Canada will come to an end, and once that has occurred, politicians will move onto knives and any other tools they can blame for violent human behavior.
American's have a significant advantage over us in that they have the right to keep and bear arms enshrined in their constitution. I would urge you to be vigilant when it comes to protecting this right. Once it's gone it's gone for good.
