This is a revised and enlarged edition of report 30 proposing a new Code of Substantive Criminal Law for Canada. The proposed Criminal Code expresses the essential principles of criminal law and rules of general application. It defines most of the crimes of concern to a modern industrialized society. At the same time, it drops archaic provisions but addresses modern day social problems like pollution and terrorism. Title I is the general part containing rules of general application; Title II contains most of the crimes against the person; Title III enumerates most of the crimes against property; Title IV lists crimes against the natural order; Title V deals with crimes against the social order; and Title VI encompasses crimes against the governmental order.
