I'm afraid I don't have the exact provisions at my fingertips but, essentially, there may not even be any need to amend the Criminal Code. I'm just not sure right now.
The jurisdiction has to be taken away, probably just in the National Defence Act. The provisions have to come back to what the law was prior to 1998. It's exactly the same for murder. The court martial system doesn't have jurisdiction over murder or over some offences involving children. These are within the exclusive jurisdiction of the civilian courts under the Canadian Criminal Code.
Whether it's both the Criminal Code and the National Defence Act, frankly, the Department of Justice could probably give you that answer in a few minutes with the provisions you need.
