It is a chicken and egg problem. Did the increasing regulation change gun culture, or did changing gun culture bring in the need for new regulations.
Even reading through this page of posts, Canadian gun culture seemed to be based historically on the fact that firearms were tools, not toys. And by this I mean that they were bought and used for hunting or protection (primarily from wildlife). Other than the wealthy, not many people bought firearms for the purpose of collecting them, or modifying them, or just to say they have the newest, bestest, most powerful (ie toys).
