This book offers a succinct and insightful discussion of the principal laws governing mergers and acquisitions transactions conducted in Canada. It draws on a collection of loosely related legal principles and rules in corporate law and securities law, as well as a handful of other areas relevant to Canadian business acquisitions. Professor Nicholls, one of Canada's leading scholars in corporate and securities law, provides a clear guide to this complex pastiche of legislation, regulation, administrative and judicial decision-making, and standard practices that have developed over time from both domestic and international precedents. This third edition discusses the implications of a host of recent legal and regulatory developments since the publication of the second edition, including, in particular, the groundbreaking changes introduced by National Instrument 62-104 in 2016. A number of recent significant judicial and regulatory decisions are also analyzed, including, among others, Tervita Corp v Canada (Commissioner of Competition), InterOil Corporation v Mulacek, Aurora Cannabis Inc (Re), Re Hecla Mining Co, and Central GoldTrust v Sprott Asset Management.
