There are a number of firearms businesses that have certain conditions on their business licence that allow them to be in possession of prohibited firearms for the purposes of their business, whether or not it is for sale to a prop house or to sell to law enforcement, for that matter. Businesses already have certain provisions that would allow them to be in possession of prohibited firearms.
I guess Randall's point was that section 22 of the firearms licences regulations already allows for businesses to have prohibited firearms in their inventory if there is a legitimate purpose to having them.
Bill C-71, however, really only speaks to the grandfathering of the firearms and the individuals in question, so I think they're two different issues.
