When the first day becomes a lifetime of harm.
A birth injury reshapes a family permanently. Where a single decision in the labour room, or one missed signal on a fetal monitor, can mean a lifetime of medical needs, therapy, equipment, and care. Paul Cahill has built much of his practice representing Ontario children and families harmed at birth, and his $11.5M jury verdict in a birth injury case is among the largest of its kind in the province. These are the cases he was built for.
Modern obstetric care has dramatically reduced birth injuries through fetal monitoring, evidence-based protocols, and timely intervention. When those tools are properly used, most catastrophic outcomes are preventable. Ontario law recognizes that not every adverse outcome at birth is the result of negligence. The legal question is whether the obstetrician, midwife, nurse, or hospital did what reasonably competent practitioners would have done with the same warning signs.
In birth injury cases, the question is rarely whether something went wrong. The question is whether it could have been prevented, and what the timely response would have changed.
The consequences of a preventable birth injury are unique. A child with cerebral palsy, hypoxic-ischemic encephalopathy, or a brachial plexus injury will need specialized care, equipment, education, and support for an entire lifetime. The damages calculations in these cases are correspondingly large, which is why they are vigorously defended and why they require counsel with the resources and resolve to take them through to verdict.
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.
Category II and III tracings indicate fetal distress and demand intervention. When these patterns are missed, misclassified, or not escalated, the baby can suffer oxygen deprivation that leads to brain injury.
Once an emergency C-section is indicated, hospitals are expected to deliver within 30 minutes. Delays in the decision, the OR setup, or the surgical team can mean the difference between a healthy baby and a brain-injured one.
HIE is brain injury caused by oxygen deprivation around the time of birth. It can lead to cerebral palsy, developmental delays, seizure disorders, or death, and is often the result of preventable failures in monitoring or response.
Not every case of cerebral palsy is caused by birth events, but a meaningful subset is. The legal question is whether the brain injury occurred during labour or delivery and whether it could have been prevented.
Nerve damage to the shoulder and arm caused by excessive lateral traction during delivery, often during shoulder dystocia. Severe cases result in permanent loss of arm function.
When the baby's shoulder gets stuck behind the mother's pelvic bone, structured maneuvers (like McRoberts and suprapubic pressure) must be applied in sequence. Improper technique can cause both nerve damage and oxygen deprivation.
Instrumental delivery requires proper indication, technique, and limits on attempts. Misuse can cause skull fractures, intracranial hemorrhage, facial nerve damage, and scalp injuries.
Preeclampsia, eclampsia, postpartum hemorrhage, and amniotic fluid embolism require recognition and rapid response. Failure to manage these conditions can lead to maternal injury or death, as well as harm to the baby.
Three legal elements must be proven on a balance of probabilities. In birth injury cases, causation is almost always the hardest battle, and damages are typically the largest in medical negligence law.
That the obstetrician, midwife, labour and delivery nurse, anesthesiologist, or hospital failed to do what reasonably competent practitioners would have done with the same clinical picture. Established through expert evidence from obstetricians, maternal-fetal medicine specialists, and L&D nursing experts.
That the breach caused or materially contributed to the injury. In HIE cases, this means proving the brain damage was caused by an event around delivery rather than antenatal factors. Pediatric neurology, neuroradiology, and placental pathology experts speak to the timing and mechanism of injury.
The lifetime cost of caring for the injured child. This includes future medical care, therapies, equipment, attendant care, special education, lost earning capacity, home modifications, and pain and suffering. Quantified through pediatric specialists, life-care planners, and economists.
Birth injury claims involve some of the most complex causation evidence in medicine, the largest damages awards in tort law, and some of the most aggressive defence strategies in Canadian litigation. Knowing what you are up against is part of choosing the right counsel.
The defence will routinely argue that the brain injury was antenatal (occurring before labour) rather than perinatal (around delivery), and therefore not preventable by anything the obstetric team did. Distinguishing the two requires expert evidence on MRI patterns, cord blood gases, Apgar scores, placental pathology, and the timeline of fetal heart rate changes. This is the heart of nearly every HIE case.
Birth injury claims attract the most intensive defence in Canadian medical litigation because the damages can be enormous. Doctors are defended by the Canadian Medical Protective Association (CMPA), hospitals by HIROC. Both will spend substantial sums on expert witnesses and trial preparation. Settlements are not freely offered. Cases get tested.
A single birth injury case may require an obstetrician, a maternal-fetal medicine specialist, a labour and delivery nursing expert, a pediatric neurologist, a neuroradiologist, a placental pathologist, a neonatologist, a life-care planner, and an economist. Securing experts of this calibre is expensive and one of the reasons many lawyers decline to take these cases on.
A complete birth injury investigation requires the prenatal record, fetal monitor strips, labour and delivery notes, operative reports, anesthesia records, neonatal resuscitation records, NICU charts, placental pathology, and the child's ongoing medical and developmental records. Obtaining and analyzing all of this is foundational work that takes time to do correctly.
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. Birth injury cases turn on records and witness recollections that can degrade over time. Earlier review preserves your options.
Under Ontario law, the limitation period for a minor's own claim is generally suspended until they turn 18 (with the two-year clock typically starting from that point). This does not mean families should wait. Evidence is freshest, witnesses are reachable, and records are most complete in the first years after the injury. Medical and life-care needs also begin immediately. Earlier review benefits the case in every respect, even when the formal limitation clock has not started running.
Birth injury cases reward depth, expert evidence, and a credible willingness to take complex causation through to trial. Paul has done exactly that, with one of the largest birth injury jury verdicts in Ontario.
