Yes, okay.
I do not consider it abnormal for there to be overlaps in jurisdiction in a federation. Consider health. Consider criminal law. I will refer to the decision in Canada Western Bank v. Alberta. Since banks sell insurance, there is an overlap when they promote insurance. The same thing applies to regulation, whether federal or municipal, as regards the environment. There will be overlaps.
In my opinion, the effects of Bill S-201 are purely incidental to provincial jurisdiction. If the provinces want to legislate, we can say that they have the jurisdiction to do so under the double aspect doctrine. All I am saying is that the incidental effects doctrine can apply. If we conclude that jurisdiction over criminal acts is not sufficient, we can use the ancillary powers doctrine initially to validate Bill S-201. If we conclude that the jurisdiction in criminal law is sufficient, we can say that it has incidental effects on provincial jurisdiction as regards private law. Once again, this justifies the constitutional validity of Bill S-201.
