In and around Markham, ERs frequently handle patients arriving with time-sensitive symptoms—things that can look “routine” at first, but become dangerous as hours pass. Common ways negligence allegations arise include:
- Triage that doesn’t match symptom risk (for example, delayed escalation when symptoms suggest something more urgent)
- Missed or delayed diagnoses after initial assessment and initial testing
- Treatment and medication mistakes that create preventable harm
- Failure to act on abnormal results, including imaging or lab findings
- Discharge issues where return precautions or follow-up guidance were inadequate for the patient’s condition
After an ER visit, it’s common to hear the defense say the outcome was unavoidable. But in medical negligence cases, the question isn’t whether the result was unfortunate—it’s whether the care met the standard expected of emergency providers and whether the breach contributed to the harm.
