As to whether negotiations have been started, I can't give you an answer. I haven't looked into those questions. However, I can tell you that both Quebec's bill and Bill C-2 specifically provide for the possibility of an agreement in cases of interprovincial or intergovernmental prosecutions. They contain specific provisions respecting those agreements. Agreements are always necessary during prosecutions, even beyond the context of the Director of Public Prosecutions. Where necessary, for example, when a case concerns the proceeds of crime, fraud or organized crime, the provinces enter into these kinds of agreements among themselves. Those are specific cases.
