There are a couple. First of all, it creates confusion for the gun-owning Canadian public. Many of the municipal agencies, provincial agencies and law enforcement agencies in this country receive action bulletins and law bulletins from the RCMP, who have been involved with or play these things out and are responsible for programs, such as the Canadian firearms program. It's possible that it could cause confusion for them. Without checking, someone could believe that this is already enacted and make an error in that regard. Thankfully, I'm not aware of anything like that happening. It was changed. But it's possible.
