When the wait becomes the harm.
Emergency departments exist to triage urgency. When the system fails, a heart attack waits in a hallway, a sepsis patient is sent home, a stroke goes unrecognized at triage. Paul Cahill represents Ontario patients and families harmed by emergency department negligence, from triage errors and discharge mistakes to hallway medicine and the failure to monitor patients whose conditions are deteriorating in plain view.
Ontario emergency departments are under sustained pressure. Wait times are long. Staff are stretched. Hallway medicine has become routine in many hospitals. Ontario law accounts for this reality, and not every adverse outcome in an overcrowded ER is the result of negligence. The legal question is not whether the system failed in general. It is whether this patient, on this day, received the care a reasonably competent emergency team would have provided in the same circumstances.
That standard can be breached even in a busy ER. Vital signs that are not retaken. A worsening patient who is not reassessed. A heart attack triaged as anxiety. A discharge that ignores red-flag symptoms. When these failures cause serious harm or death, the law allows the patient or their family to seek accountability from the physicians, nurses, and hospital responsible.
These are the patterns Paul most commonly investigates. The presence of one of them does not, by itself, prove malpractice, but it is often the starting point for a meaningful legal review.
A high-acuity presentation incorrectly triaged as low priority under the Canadian Triage and Acuity Scale, leaving a critically ill patient waiting hours when minutes mattered.
Triage protocols require re-evaluation of waiting patients. When deterioration in vital signs or symptoms goes undetected, the patient may collapse before being seen.
Sending a patient home with abnormal vitals, ongoing symptoms, or red-flag findings that warranted admission, observation, or further workup before release.
Heart attacks misread as anxiety, indigestion, or musculoskeletal pain. ECG and troponin pathways exist for a reason. Skipping or misinterpreting them costs lives.
Stroke symptoms attributed to migraines, vertigo, or intoxication. The window for clot-busting therapy is narrow. Delays in CT, neurology consult, or treatment can mean permanent disability.
Sepsis sent home as flu or viral illness. Sepsis bundles call for early antibiotics and resuscitation. Mortality climbs sharply for every hour treatment is delayed once septic shock develops.
Patients managed in hallways or temporary spaces without proper monitoring, privacy, or documentation. Charting errors and missed assessments are common in these conditions.
ER physicians who should have called a specialist, ordered imaging, or admitted the patient for observation, but instead managed beyond the scope of safe emergency care.
Three legal elements must be proven on a balance of probabilities. The standard is what a reasonable emergency team would have done in the same circumstances, not perfection.
That the triage nurse, ER physician, and hospital failed to do what reasonably competent practitioners and a reasonably resourced ER would have done in the same situation. Established through expert evidence from emergency medicine specialists and triage nursing experts.
That the failure caused or materially contributed to the injury. The defence will often argue the underlying condition was already irreversible. Causation is established through expert evidence on what timely care would have achieved compared to what actually happened.
The compensable harm caused by the breach: medical expenses, future care, lost income, loss of life expectancy, pain and suffering, and the impact on family caregivers. Quantified through medical, vocational, and economic expertise.
Emergency department litigation sits at the intersection of individual care decisions and systemic hospital pressures. Understanding both is essential to a successful claim.
ER claims typically name a triage nurse, an ER physician, possibly consulting specialists, and the hospital itself. Each is separately defended, and apportionment of liability across them is one of the central battles. Naming the right defendants in the right proportions takes careful investigation.
Doctors are defended by the Canadian Medical Protective Association (CMPA), hospitals by the Healthcare Insurance Reciprocal of Canada (HIROC). Both have substantial resources and a long history of taking strong cases to trial. Settlements are not freely offered, particularly when the defence sees a viable system-pressure argument.
Triage notes, vital sign reassessments, and nurses' charting are frequently brief, abbreviated, or missing entries that should have been made. In hallway medicine, documentation is often worse. Reconstructing what actually happened requires skilled review of the records, the timing of orders, and witness evidence.
Defendants will often argue that the ER was overwhelmed and the outcome reflects systemic strain rather than individual negligence. This argument has limits. The standard of care still applies even in busy departments. Showing where individual decisions fell below that standard, despite the chaos, is the work of the case.
Ontario's Limitations Act, 2002 generally requires civil claims to be commenced within two years of when the injury and its likely cause are discovered or should reasonably have been discovered. Hospital records and ER charts can be hard to obtain, and witness recollections fade quickly. Earlier review preserves your evidence and your options.
ER cases reward investigation, expert evidence on multiple disciplines, and a credible willingness to litigate against both physicians and hospitals through to verdict. Paul is built for all three.
