In Canada, there is a large body of statutory and common law which provides guidance about the standards of conduct expected from directors and attaches personal liability for failing to meet those standards. Directors now owe expanded duties to shareholders, employees, creditors, and other stakeholders and are increasingly being held personally responsible for the corporation’s conduct. Liability attaches under the Canada Business Corporations Act (CBCA), and under provincial corporations acts, most of which are similar to the Ontario Business Corporations Act (OBCA). This article deals only with liabilities under business corporations.
