This accessible and practical reference provides an overview of the essential features of the law governing business organizations in Canada, both in theory and practice. It is a comprehensive and up-to-date guide for practitioners and business people setting up and using sole proprietorships, partnerships and corporations to carry on small businesses as well as a thorough introduction to the law and policy of public company governance. The fourth edition has been fully updated to reflect developments in the caselaw and statutory reforms in the last decade. Dozens of new cases are cited. The 2018 amendments to the Canada Business Corporations Act are discussed, including the requirements for public corporations to report on the diversity of their boards of directors that are not yet in force. The chapters on securities law, corporate governance, and corporate social responsibility have been significantly expanded. As well, features to improve the utility of the book have been added, such as more comprehensive cross-referencing throughout the text.
