When a patient or resident in a controlled care environment suffers harm, whether through an error in medication administration, a failure to prevent a foreseeable injury, or an adverse event during treatment, the moments and days that follow create a critical juncture for healthcare professionals, administrators, and the institutions they represent. The obligation to disclose what has occurred exists at the intersection of law, ethics, and professional standards, creating a framework that governs how Canadian healthcare providers must respond when things go wrong. Understanding these obligations is not merely an academic exercise but a practical necessity for anyone working in environments where vulnerable individuals depend on others for their care and safety.
The duty to disclose harmful incidents to patients and, where appropriate, to their families or substitute decision-makers arises from multiple sources within Canadian law and professional regulation. At its foundation lies the common law principle of informed consent, which courts across Canada have consistently interpreted to include not only the right to information before treatment but also the right to know what has occurred after treatment, particularly when that treatment has resulted in harm. This principle recognizes that the fiduciary relationship between healthcare providers and patients creates ongoing obligations that do not cease when an adverse event occurs. Patients retain the right to make informed decisions about their ongoing care, to seek additional treatment, to understand the implications of what has happened to their bodies, and to pursue legal remedies if they choose. None of these rights can be meaningfully exercised without truthful and timely disclosure of the facts.
