Current to August 2026

Ontario legal information · Ottawa and Eastern Ontario

01 · Understanding the issue

What the page should help you decide

Reibl locates inadequate disclosure in negligence and sets a modified objective approach to causation.2

The current Health Care Consent Act also governs consent in Ontario; capacity, voluntariness and treatment-specific information must be considered.

02 · Insurance and responsibility

Keep the legal question, insurance route and next practical step distinct.

Legal question

A disclosure claim differs from a claim that the procedure itself fell below the standard of care.

Coverage or process

Emergency, capacity and substitute-decision situations require their own analysis.

Practical step

The patient must connect the undisclosed material risk to the decision and resulting injury.

03 · Evidence

Build the answer from records another person can check.

01Event and responsibility

What the clinician knew about the patient and proposed treatment.

02Health and causation

Risk, alternatives, prognosis and actual complication.

03Function and loss

Patient goals, questions and decision constraints.

04Documents and decisions

Notes, handouts, consent form, witnesses and expert opinion.

The paper form is one part of the discussion, not the discussion itself.
04 · Timing and decisions

Protect the next real date.

Memories fade, so record the conversation while details remain available.3

Do not assume the date of surgery is the only possible limitation date.

05 · When legal help may matter

How a medical malpractice lawyer may help assess this concern.

A poor outcome is not enough by itself. The legal review must separate the medical question, the standard of care, causation and the additional loss said to result.

  • Identify material risks
  • Reconstruct the discussion
  • Separate disclosure from performance
  • Test decision causation

Not every file requires every step or legal representation. The work should respond to the actual dispute, evidence gap or decision that is approaching.
