You're right that having a list of prohibited weapons is what happened. In fact, that's the approach that was taken in the 1990s, and the lists were never updated. Having just lists means that you depend on future governments to update the list, which was not done under either government. That's how we found ourselves, years later, with a market full of military-style semi-automatic assault weapons.
In terms of the definition, we're not ballistics experts. We know what the semi-automatic military-style weapons are capable of, especially with large capacity magazines. The same weapons that are used in the United States in all of the mass shootings were legal here. Some continue to be.
In terms of definitions, there are different ways to go at it. The Bureau of Alcohol, Tobacco, Firearms and Explosives in the United States has a list of criteria that can be used to determine whether or not a weapon is military-style. I think California also has a definition, which includes all semi-automatics that can accommodate magazines and have at least one other military feature. That's probably as far as we would go. We would also point to the New Zealand model, which is most centre-fire semi-automatics that can accept large capacity magazines.
That's pretty much as far as we can go, but like Nathalie and Meaghan said, if a gun is able to be used to kill dozens of people in a matter of seconds, it should not be in the hands of an ordinary Canadian. We will defer to the experts—your experts and the experts of the government and the RCMP—to draw that line, which we know won't be easy, but currently the orders in council and the criteria that are in there do not cover all assault weapons, and that needs to change. We've been fighting for that for 33 years, and that's our top priority.
