In theory, that's exactly how it should work, but in practice, it doesn't work that way. When the RCMP issues a bulletin with their.... Remember, it's nothing more than a legal opinion at this point. With their legal opinion, it has the force of law. In other words, individuals are arrested for it and they can be convicted and prosecuted. The Canada Border Services Agency, if they take that decision and disseminate it to all border crossings, will charge individuals with attempting to import what are now prohibited firearms but yesterday were non-restricted firearms, or sometimes even non-firearms at all.
I agree in theory that's how it should work, but that's not how it works and Parliamentary oversight is the only check on that power. For example, when the Swiss Arms or the CZ858 was classified, Parliament was able to say, “There's a problem here. There's a fundamental unfairness, and we're going to grant an amnesty.” That can't happen anymore under Bill C-71.
