The “casebook” revision seeks to provide a comprehensive, yet concise ethical resource grounded in the Canadian ethical landscape for counsellors and psychotherapists across their professional journey from student to experienced practitioner, supervisor, educator, and beyond. Building from the foundations of ethical practice (e.g., theoretical, philosophical, and contextual), the casebook will explore how our professional histories have shaped modern conceptions of ethical principles and ethical decision making, as well as future directions and possibilities. Rooted in the current ethical realities and challenges of today’s counsellors/psychotherapists, practical cases will be explored through multiple lenses. Readers will leave with a deepened appreciation and understanding of the complexity of addressing ethical dilemmas and navigating ethical issues within the complex systems in which counsellors work.
