Legalizing airsoft is not an idea to be casually tossed about.
Many newbies have had very short stays here on ASC, because they spent most of their time arguing that there should be some sort of legalization moment without actually having any notion of what's involved.
In the end, if you need to ask about the legal history of airsoft guns in Canada, you're the last person that should be suggesting a moment to legalize it. No offence intended.
