I've been gone from here for awhile and I finally found this comic.
When I was going to college I worked at the Wal-Mart gun counter and quickly earned a reputation as the "gun guy". (I still am one.

) Plenty of Canadians came down to buy ammo and would openly admit to owning unregistered guns. From what I was told, the registry is largely unenforced because the police know it's useless and siphons resources from where they might be better used. Thus nobody is arrested over it unless they are committing some other crime.
Getting rid of it would be good for all of Canada, not just the gun owners, for the reasons listed above.
Of course most of the Canadians you spoke to would be anti-registry. They took the trouble to buy from your place rather than go someplace closer and register.
However, I do agree that gun registry is little more than a polite formality when it comes to otherwise-law-abiding gun owners who do not use their firearms regularly.
