Operational risk sits at the heart of every organization, whether that organization is a multinational corporation with thousands of employees or a sole proprietor running a consulting practice from a home office in Halifax. Unlike market risk or credit risk, which tend to occupy the attention of financial institutions and investment professionals, operational risk affects every business, every non-profit, and every professional practice in Canada. It is the risk of loss resulting from inadequate or failed internal processes, people, and systems, or from external events. This definition, drawn from the Basel Committee on Banking Supervision's framework and adopted in various forms by regulators and standard-setting bodies around the world, captures something essential about how organizations actually function and fail. The Canadian Securities Administrators, the Office of the Superintendent of Financial Institutions, and provincial regulators across the country all incorporate operational risk considerations into their oversight frameworks, though the specific requirements vary by sector and jurisdiction. As of the date of authorship, the International Organization for Standardization's ISO 31000:2018 standard on risk management provides a widely referenced framework that Canadian organizations of all sizes can adapt to their circumstances, offering principles and guidelines that translate well across industries from resource extraction in northern Alberta to professional services firms in downtown Toronto.
