Canadian securities law comprises a unique mix of enduring basic principles and constantly-changing technical details. This new book, by Jeffrey MacIntosh and Christopher Nicholls, provides a solid introduction to both. The book includes a survey of all of the “usual” securities law topics—including basic definitions, the public and exempt markets for securities, insider trading, continuous disclosure, take-over and issuer bids. But the discussion of these and other specific topics is interwoven with a careful consideration of larger public policy issues. The authors thus help guide the reader through the complex labyrinth of modern securities regulation by constantly highlighting the unifying thread of fundamental principles.
