After nearly two decades of representing patients and families harmed by medical care in Ontario, this is the question I hear most often on a first call. The honest answer is one most prospective clients are not prepared for. Yes, you can sue. But before you do, you should understand what these cases actually involve, because in many situations the most candid advice a medical malpractice lawyer can give is to think very carefully before going forward, and in some cases not to go forward at all.
What follows is the reality I walk new clients through every day:
- What medical malpractice claims are actually about, and the limits on what they can deliver
- How hard it is to prove a claim
- How expensive it is to run one, and how often these cases actually settle
- What happens when there is no viable lawsuit
- The limitation period trap
Medical Malpractice Claims Are About Compensation, and Compensation Has Limits
The civil justice system in Ontario allows a person who has been injured by the fault of another to sue for money. That is what these cases are about. They are not primarily about discipline, accountability, or making sure the same thing does not happen to someone else. Those goals belong to other systems. Civil litigation is a mechanism for transferring money from one party to another after a finding of legal fault.
That matters because most prospective clients come in believing the harm they suffered is, on its own, enough to justify a claim. Often it is not. Ontario law sets clear, and in many cases disappointingly modest, limits on what can be recovered.
Pain and Suffering (General Damages). General damages are capped in Ontario at roughly $450,000. That cap applies regardless of how badly someone was hurt or how dramatically their life has been altered. In American jurisdictions without caps, the same injury might attract a far higher award. In Ontario, the answer is the same number for everyone at the most serious end of the scale. Most clients, particularly families bringing fatal injury claims, are stunned by how little this category delivers relative to what has happened to them.
Income Loss. There is no cap, but income loss is only meaningful where there is income to lose. For a young child, a retired person, or someone who was not working at the time of the negligence, this category may produce little or nothing. In a birth injury claim involving a child who will never be able to work, an economist can project what the child might have earned, but that projection requires expensive expert evidence and is heavily contested by the defence.
Cost of Care. There is no cap here either. In catastrophic cases, particularly birth injury, cost of care can run into the millions. But these are the exception, not the rule. In many medical malpractice cases the patient’s needs are met through OHIP, family support, or community programs, and the additional cost of care claim is modest. Without significant cost of care or income loss, even a meritorious claim can fail to justify the cost of pursuing it.
There is one piece of structural good news, and one significant piece of bad news. The good news is that physicians face no cap on the indemnity available to them through the Canadian Medical Protective Association (CMPA). The bad news is that the CMPA is not an insurance company. It is a mutual medical defence organization that exists to protect the professional reputation of Canadian physicians. It does not exist to settle claims efficiently on behalf of sympathetic patients harmed by the medical system.
In practice, that means almost every medical malpractice claim is contested. Hard. By experienced defence counsel with a national budget. The CMPA is not motivated to settle a case it believes it can win, and it is prepared to fund a defence all the way to a verdict. Patients who go up against this system are not negotiating with an insurer trying to control its costs. They are litigating against an organization whose institutional interest is in defending its members.
The Legal Requirements Are Demanding, and Many Real Mistakes Will Not Meet Them
There is a fundamental gap between “bad medical care” and “medical malpractice in the legal sense.” Many prospective clients describe care that was, by any reasonable standard, poor. A meaningful number of those cases are still not winnable.
Three elements must be proven on a balance of probabilities for a claim to succeed.
Standard of Care. This is what a reasonable and prudent physician would have done in the same circumstances. Physicians are not held to perfection. They are entitled to make difficult judgment calls, including ones that turn out badly, without being negligent. The defence will retain respected experts who will explain, persuasively, why the physician’s conduct met the standard. Disagreements between qualified experts are common, and they are not automatically resolved in the patient’s favour.
Causation. This is where many otherwise compelling cases fail. Even where a physician clearly fell below the standard of care, the plaintiff still has to prove that the substandard care actually caused the harm. That is often unclear on the medicine. The patient may have had a serious underlying condition. The bad outcome might have happened anyway. A delay in diagnosis might not have changed the prognosis. Medical malpractice cases routinely turn on causation, and causation is genuinely difficult to prove.
Damages. Even where the first two elements are made out, the plaintiff still has to prove that the harm produced compensable damages, and that those damages are significant enough to justify the cost of pursuing the claim. Where damages are modest, the economics of the litigation may not work, no matter how clear the negligence.
The proof on all three elements comes from expert evidence. Your lawyer must find qualified physicians who are prepared to testify against another physician. That is harder than it sounds. Most physicians do not want to testify against colleagues. The pool of credible plaintiff experts is small. The defence has a deeper bench, more time, and more money.
The Cost Is High, and the Odds Are Not What People Expect
Contingency fee agreements make it possible to bring these cases without paying legal fees up front. They do not make these cases cheap.
Specialized legal services. Medical malpractice work requires lawyers who understand both the law and the medicine, and who have spent years building relationships with experts willing to give evidence. That specialization is reflected in the notional rates these cases command, and in the years of work each case typically demands.
Expert fees. Experts charge by the hour to review records, prepare reports, and testify. Total expert fees of $100,000 by the time a case reaches trial are routine. In complex birth injury matters, expert fees can be multiples of that. These are not “if we win” costs. The disbursements have to be funded as the case proceeds, by someone, and that someone is usually the law firm.
Settlement rates that do not look like other litigation. It is well known among civil litigators that roughly 99% of civil lawsuits settle. Medical malpractice does not. Only about 30% of medical malpractice claims settle. The rest are abandoned, dismissed, or proceed to trial with mixed results. These are not the odds most people think they are facing when they walk into a lawyer’s office.
The combination of high cost, hard liability, hard causation, and a low settlement rate means that experienced plaintiff lawyers decline most of the cases they review. That is not because the underlying care was acceptable. It is because the case is not viable on the economics or on the law. Some patients with real, painful injuries simply will not find a lawyer who will take their case on. That is not a failing of the lawyer. It is a feature of the system.
If you have already been turned down by one experienced medical malpractice lawyer, it is worth knowing that you may be turned down again. A second opinion is sometimes worth seeking, particularly where the first review was cursory. But most plaintiff firms working in this area see roughly the same issues the same way, and they decline cases for the same reasons.
When There Is No Viable Lawsuit, There Are Still Other Avenues
A patient who concludes, on legal advice, that civil litigation is not realistic is not without options. They are, however, options that do not produce financial compensation.
The College of Physicians and Surgeons of Ontario (CPSO) regulates the practice of medicine and accepts complaints from members of the public. The CPSO will investigate, usually over a period of 8 to 12 months, and issue a written decision and reasons. Complaints against nurses go to the College of Nurses of Ontario, with a similar process. Every regulated health profession has its own College, and each has a public complaints process. Hospitals also accept patient relations complaints, though a hospital’s authority is limited because physicians are independent contractors, not hospital employees.
I encourage patients to use these processes when they believe something has gone wrong. They serve a real public safety function and they sometimes lead to changes in practice. They will not, however, deliver compensation, change the result in a related civil case, or stop the limitation clock from running on a lawsuit. Patients should not assume that a regulatory complaint is a substitute for legal advice, and they should not delay obtaining that advice while waiting for a College outcome.
The Limitation Period Trap
Ontario law generally requires a medical malpractice claim to be issued by the Ontario Superior Court of Justice within two years of the negligent act, or within two years of the date the patient knew, or reasonably ought to have known, the material facts on which the claim is based.
That sounds straightforward. It rarely is.
Medical malpractice cases involve outcomes that may not look like negligence at the time. A surgical complication might present as a known risk, until investigation suggests it was not. A misdiagnosis might be discovered only when a cancer returns or progresses. A medication error might come to light only after a reaction. Whether the discoverability clock had started running, and when, is regularly contested by the defence, and that argument can end an otherwise meritorious case before it has been fully heard on the merits.
For minors and adults without capacity, the clock does not run while they are legally unable to instruct a lawyer. For everyone else, the limitation period is unforgiving. By the time a patient has finished with a College complaint, sought a second medical opinion, recovered enough to think about a lawsuit, and started looking for a lawyer, the two years can already be gone.
The practical message is simple. If you suspect something has gone wrong with your medical care, do not wait. Speak to a lawyer who actually practises in this area, and do it well before the second anniversary of the event. Most lawyers in this field will not take a case where the limitation period has expired or is about to expire. The work required to defeat a limitation defence is, on its own, often more than a contingency fee practice can absorb on a marginal case.
A Final Word
The civil justice system in Ontario is a real avenue for compensation in medical malpractice cases. For a small number of patients and families, particularly those facing catastrophic, lifelong consequences from clearly substandard care, it can make a meaningful difference. For many others, the legal standard, the cost, the timeline, and the strength of the defence will mean that the right advice, candidly given, is that a lawsuit is not in their interest.
That is not a reason to avoid speaking to a lawyer. It is a reason to choose one who will tell you the truth about your case, including when the truth is that pursuing it would do more harm than good.
