The evidence a claim stands or falls on.
Medical malpractice cases are built on documents. However concerning an outcome may be, and however clear the explanation given afterwards may seem, the question a court asks is what the contemporaneous record shows. No responsible assessment of a case can be made without reading it.
Patients and families are often given an account of what happened, sometimes at a meeting arranged after the event. Those accounts may be entirely sincere. They are not evidence of what was known, considered or decided at the time.
The record is different because it was created while the care was being delivered. It captures what the patient reported, what was examined, what was ordered, what came back, what was prescribed or withheld, and how the clinical picture changed. It was written before anyone knew there would be a claim, which is precisely why courts prefer it to testimony given years later.
A malpractice claim in Ontario requires proof of a standard of care, a breach of it, causation, and damages. The record does distinct work on each.
Expert opinion on what a reasonable practitioner should have done depends entirely on what information was in front of the practitioner at the time. The record establishes that, which is why the standard is assessed without the benefit of hindsight.
The record is where a departure becomes visible: a symptom documented and not investigated, an abnormal result filed without follow-up, deteriorating vital signs that prompted no reassessment, a consultation requested but never completed.
Usually the hardest element, and built almost entirely from chronology. Proving that earlier or different care would probably have changed the outcome requires knowing when the opportunity to intervene existed and how long it stayed open.
The extent of the injury, the complications that followed, the treatment required, and the effect on function and earning capacity are all documented across the subsequent records, often for years afterwards.
A fuller account of how these elements are weighed at the outset of a case is set out in how we evaluate medical malpractice cases in Ontario.
Records relevant to a single episode of care are frequently held by several unconnected providers, and the ones that decide cases are not always the obvious ones.
Including the cumulative patient profile, which shows the longitudinal picture a treating physician had available.
Triage assessments, reassessment times, and ambulance call reports where the patient arrived by paramedic.
A discharge summary is a retrospective account. The progress notes are what was written as events unfolded.
Contemporaneous, frequently more detailed than the physician record, and commonly where a deterioration first appears in writing.
Observation charts, telemetry and fetal monitoring strips, which often carry timings nothing else records.
The requisition shows what was asked for and why, which is often more revealing than the report itself.
Results, and critically the time each result was reported and to whom it was reported.
Consultation requests, any answering letter, and the medication administration record.
What is absent is as significant as what is present. A referral with no answering consultation note, an ordered test with no result, a critical imaging finding with no record that anyone was told: these are the gaps a review is specifically looking for.
Records are not read in the order they arrive. They are merged onto a single timeline, so that what one clinician knew at a given hour can be compared with what another had already written down. Patterns emerge that are invisible in any individual chart.
An abnormal finding available for hours or days before anyone responded to it. The record shows both when it landed and how long it sat.
Repeat attendances with the same complaint, each assessed as though it were the first. The pattern only appears when the visits are read together.
A finding documented by one clinician and absent from the next set of notes. Shift changes and transfers between facilities are where this happens.
A patient sent home while a documented abnormality remained unexplained. This is the central issue in most delayed diagnosis claims.
A case of any complexity runs to hundreds or thousands of pages, often handwritten and inconsistently paginated. The review is also the stage at which many enquiries turn out not to support a claim, which is part of why many cases are declined.
The limitation period in Ontario generally runs from the point at which a claimant knew, or ought reasonably to have known, that an injury had occurred and that it may have been caused by someone's act or omission. In malpractice cases that knowledge often arrives only when the records are read. The clock is not extended by the time spent gathering the evidence needed to assess the claim.
Patients in Ontario have a statutory right of access to their own health records under the Personal Health Information Protection Act, and a custodian must ordinarily respond to a written request within thirty days.
Each provider holds only its own records, so a request has to go to every clinic, hospital, laboratory and imaging facility involved. Hospital records departments will often produce a summary set unless the request specifies nursing notes, flow sheets, monitoring strips and imaging on disc. The practical mechanics, including what to ask for and what a provider may charge, are covered in how to get your medical records in Ontario.
Partial records are worse than no records, because they invite confident conclusions on incomplete information. An expert asked to comment on a subset of a chart may reach an opinion that a complete set would have reversed, in either direction.
Internal hospital quality of care review documents occupy a separate and protected category, as the decision in Algarawi v Berger illustrates. A patient may hold the complete clinical record and still not have the institution's own analysis of what went wrong.
Because that material sits outside what you can obtain, the fact that a hospital reviewed an outcome internally is not, on its own, an indication that a claim exists or that it does not. The clinical record still has to be assessed on its own terms.
A few steps make a later assessment substantially easier, and none of them commits you to anything.
From every provider involved, not just the one where the problem occurred. Early requests protect your options later.
Symptoms, appointments, and what you were told at each one, while it is still fresh in your memory.
Test results, reports, appointment records and correspondence, including messages sent through a patient portal.
Including walk-in clinics and out-of-town hospitals. Records are easy to miss when care was spread across facilities.
Reading the record of a serious injury is difficult, and it is reasonable to want someone else to do it. It is also, in most cases, the only way to find out whether what happened was a recognised complication of properly delivered care or something that should not have happened at all. Either answer is worth having.
