Waiting 48 Hours in the Emergency Room: When Does a Delay Become Negligence?

A new report finds one in 10 admitted patients now spend more than 48 hours waiting in the emergency department, and roughly 16,000 died while waiting for care last year. But a broken system is not the same as a winnable malpractice claim. Here is where an ER delay can cross into negligence in Ontario, and where it cannot.

A national report released this week put a hard number on something patients have felt for years. According to the Canadian Institute for Health Information, one in 10 people admitted to hospital in 2024-2025 spent more than 48 hours waiting in the emergency department before they got a bed, up from a comparable 36 hours in 2018-2019. The report points to an aging population, an overburdened system, and a shortage of inpatient and long-term-care beds that stalls both admissions and discharges.

The human version of that statistic is easy to picture. The report’s release coincided with CBC’s account of an 81-year-old Windsor woman who was taken to an emergency room after a fall and was still waiting in a hallway for a bed more than two days later. She is not unusual. CIHI’s director of health system analytics reported that roughly 16,000 patients died while waiting for care last year, and that about two-thirds of emergency room patients now arrive needing immediate or urgent treatment. Roughly half a million Canadians left the emergency room before being seen at all.

For patients and families, the natural question is whether a wait this long, with this much documented harm, is something the law treats as negligence. The honest answer comes in two parts, and they pull in opposite directions.

A broken system is not, by itself, a malpractice claim

Overcrowding, hallway medicine, and multi-day admission delays are overwhelmingly the product of policy and funding decisions: how many beds a hospital is resourced to staff, how many long-term-care spaces exist to move patients into, how many people can see a family doctor instead of an emergency room. The report itself concludes that the fix has to start outside the emergency department. That is a fair diagnosis, and it is also the reason these problems are so hard to litigate.

Canadian courts have generally been cautious about turning a government’s funding and resource-allocation choices into a basis for negligence liability. They tend to separate genuine policy decisions, which are largely insulated, from the operational delivery of care to an individual patient, which is not. A patient usually cannot sue because the province under-resourced its hospitals. “The system is broken” is true, and it is not a cause of action.

I have written before about how overcrowded emergency rooms can lead to medical malpractice, and the distinction there is the one that matters here: the system creates the conditions, but liability still attaches to people and institutions, not to a budget line.

The standard of care does not disappear because the department is full

The duty a physician or nurse owes the patient in front of them is not suspended by volume. Inside a crowded emergency room, providers are still expected to triage appropriately, to reassess a patient whose condition is changing, to escalate when warning signs appear, and not to discharge or lose track of someone who is deteriorating. A busy shift is part of the context a court weighs. It does not reduce the standard to zero.

It is worth being precise about what the standard of care is, because it is tempting to assume a bad outcome speaks for itself. What the standard required in any particular case is a question of expert evidence, established by physicians in the relevant specialty (emergency medicine, internal medicine, and so on). It is not something a headline, a statistic, or a patient’s own sense of how long was “too long” can settle.

Where harm does flow from an individual provider falling below that standard (a missed reassessment, ignored vital signs, a premature discharge), a claim can lie even though the backdrop is a system in crisis. Hospitals can be on the hook as well: vicarious liability for the negligence of their nurses and staff, and in some cases direct liability for inadequate systems or protocols. Those institutional claims are harder, because courts still try to separate operational failures from constraints that were genuinely unfunded. But they are not impossible. In one Ontario matter, a failure to admit a patient in acute crisis contributed to a catastrophic injury and a significant settlement.

Causation is where most of these cases are won or lost

Even a clear delay does not, on its own, prove a claim. The patient has to show, on a balance of probabilities, that the delay (and not the underlying illness) caused or materially contributed to the injury. That is the “but for” test the Supreme Court of Canada confirmed in Clements v Clements, 2012 SCC 32, [2012] 2 SCR 181.

This is why the report’s most alarming figure needs to be read carefully. About 16,000 people died “while waiting for care.” Dying after a long wait is not the same as dying because of it. Many of those patients arrived with conditions that carried a poor prognosis no matter how quickly they were seen. Proving the counterfactual (that earlier admission or treatment would probably have changed the outcome) takes expert evidence, and it is often genuinely contestable. Canadian law is also restrictive about compensating a lost chance of a better outcome, which raises the bar further.

None of this runs one way in the plaintiff’s favour, and it should not be presented that way. Courts regularly dismiss delay and missed-diagnosis claims where the emergency room met the standard of care, or where causation simply cannot be proven. In one pneumonia death, the court found the emergency room had met the standard of care despite a tragic result. A long wait makes a poor outcome more likely. It does not make a lawsuit a foregone conclusion.

What this means if you or a family member was harmed

The legal question is narrower than the headline. It is not “was the emergency room overwhelmed.” It is “did a specific provider fall below the standard of care, and did that probably cause the harm.” Those questions are answered with the chart, not with the news.

A few practical points follow from that. Write down the timeline while it is fresh: when you arrived, when you were triaged, who saw you and when, what you were told, and the moment things changed. A complaint to the College of Physicians and Surgeons of Ontario or to the hospital is worth understanding, but it is not the same as a civil claim: a complaint is about professional accountability and public protection and brings no compensation, while a lawsuit is about compensation and has to be proven separately. And the limitation periods are strict, so timing matters.

If you believe negligent care, rather than an overwhelmed system, contributed to a serious injury or a death, it is worth getting advice early. You can start with my overview of suing for medical malpractice in Ontario, and then have the specifics reviewed against the records.

The 48-hour number is a policy failure that the whole system has to own. Whether a particular delay was also negligence is a different and much narrower question. It is the one worth asking carefully, with the records in hand.
