In Chapters 1 to 4, this monograph introduces the legal system of four English-Language jurisdictions, namely Australia, Canada, New Zealand and the United States of America, and then considers the regulators, and some of the laws that regulate, transactions in corporate securities there. Chapter 5 is comprised of concluding comments, based upon the work performed for the earlier chapters. Canadian securities’ law is enacted by administrations in its constituent provinces and territories, rather than by the federal Government, which creates a point of interest for this book.
