Representing Victims of Medical Malpractice Across Ontario
Standard of care is the legal benchmark for the conduct expected of physicians, nurses, and other regulated health professionals in Ontario. It is the first of the three elements a plaintiff must prove in a medical malpractice claim, and it is almost always proven or defended through the evidence of qualified medical experts.
Posts tagged Standard of Care analyze how Ontario courts have applied the test in specific cases, how expert evidence is used to define what a reasonable practitioner would have done in the circumstances, and where the standard is contested between specialties. The library covers obstetrical, emergency, surgical, anesthetic, and primary care decisions, along with appellate rulings that shape how trial courts approach the question.
