Bill C-42 does not contain any provision to limit the power of chief firearms officers. The bill simply entitles the Government of Canada to limit those powers through regulation, if need be. That is all. The government is giving itself the power to ensure that the national program will continue to be a national program. If need be it can bring in regulations. However, no such measure is currently included in the bill.
