A Cancer Diagnosis Without a Biopsy, Unnecessary Palliative Treatment, and a Settlement
A settlement on behalf of a patient diagnosed with terminal metastatic cancer based on imaging alone, who lived for an extended period under a wrong diagnosis.
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.
For patients considering a claim, these case comments offer a sense of what Ontario courts have treated as a departure from the standard of care and what they have not.
