Representing Victims of Medical Malpractice Across Ontario
The Court of Appeal for Ontario is the province’s highest court and the final domestic appellate court for most Ontario medical malpractice decisions, given the rarity of leave being granted to the Supreme Court of Canada. The Court of Appeal hears appeals from final orders of the Superior Court of Justice (other than family law matters) and from select decisions of the Divisional Court.
In medical malpractice litigation, the Court of Appeal’s role is doubly important. Its decisions are binding on every trial-level judge in Ontario, and its analysis of standard of care, causation, expert evidence, and damages frames how the trial bench approaches these issues. Recent decisions have refined the application of the Clements v Clements causation framework, addressed the limits of permissible expert opinion under White Burgess Langille Inman v Abbott and Haliburton Co, and continued the appellate court’s long line of decisions on the Reibl v Hughes informed consent test.
