The Landscape of Non-Physician Healthcare in Canada
Canada's healthcare system extends well beyond physicians and hospitals. Millions of Canadians receive care each year from physiotherapists, chiropractors, naturopathic doctors, acupuncturists, massage therapists, and a wide range of other alternative and complementary medicine practitioners. Most of these interactions are safe and beneficial. But when something goes wrong, patients often do not know that they have legal rights, or that the same negligence framework that applies to physicians extends to the full spectrum of regulated and, in many cases, unregulated providers.
Who Is Covered by This Guide
This guide addresses malpractice and negligence claims arising from treatment by:
- Physiotherapists (physical therapists)
- Chiropractors
- Naturopathic doctors
- Acupuncturists and traditional Chinese medicine practitioners
- Massage therapists
- Other alternative and complementary medicine practitioners, including those offering treatments that are legally available in Canada but carry significant or not fully understood risks
Why These Claims Differ from Physician Malpractice
Several features distinguish malpractice claims against these practitioners from claims against physicians.
The regulatory landscape is more fragmented. Some professions are fully regulated with robust college complaint processes in all Atlantic provinces; others are regulated in some provinces but not others; and some are essentially unregulated, meaning there is no professional body to which a complaint can be filed alongside a civil claim.
The insurance picture is different. Physicians are almost universally defended by the Canadian Medical Protective Association (CMPA). Chiropractors, physiotherapists, and naturopathic doctors carry various forms of professional liability insurance through private insurers or association programs. Unregulated practitioners may carry no insurance at all.
The standard of care is discipline-specific. A chiropractor is not held to the standard of a physician; they are held to the standard of a competent chiropractor. A naturopathic doctor is expected to practice within their own professional standards. This discipline-specific standard shapes both the content of the claim and the type of expert required to establish it.
The Shared Legal Framework: Negligence Applies Across All Professions
Regardless of the practitioner's designation, a malpractice claim in Canada requires proof of the four elements of negligence, a framework that builds on the duty of care (the “neighbour principle”) established in Donoghue v Stevenson [1932]:
- A duty of care existed between the practitioner and the patient
- The practitioner breached the standard of care applicable to their discipline
- The breach caused the patient's harm
- The harm resulted in measurable damages
A duty of care arises as soon as a therapeutic relationship is established, when a practitioner agrees to assess or treat a patient. It does not matter whether the practitioner is a physician, a physiotherapist, or an unregulated energy therapist: if they have undertaken to provide care and a patient reasonably relied on their skill and judgment, a duty of care exists.
A Note on Alternative and Experimental Treatments
Who Regulates These Professions in Atlantic Canada?
Regulation determines who is legally authorized to practice, what standards apply, what complaint mechanisms are available, and what happens if a practitioner causes harm. The regulatory landscape varies significantly across Atlantic Canada and across professions.
Physiotherapy
Physiotherapy is fully regulated in all four Atlantic provinces. Each province has a dedicated regulatory college that sets standards, investigates complaints, and disciplines members:
- Nova Scotia: Nova Scotia Regulator of Physiotherapy (NSRPT), formerly the Nova Scotia College of Physiotherapists
- New Brunswick: College of Physiotherapists of New Brunswick
- Prince Edward Island: Prince Edward Island College of Physiotherapy
- Newfoundland and Labrador: Newfoundland and Labrador College of Physiotherapists (NLCP)
All registered physiotherapists in Canada must pass the national competency examination administered by the Canadian Alliance of Physiotherapy Regulators (the Canadian Physiotherapy Examination, which replaced the former Physiotherapy Competency Examination in 2026) and hold a licence from the college of the province in which they practise.
Chiropractic
Chiropractic is regulated in all four Atlantic provinces, each with its own regulatory structure: the Nova Scotia Chiropractic and Naturopathic Regulator (NSCNR, formerly the Nova Scotia College of Chiropractors); the New Brunswick Chiropractors Association; the PEI Chiropractic Association; and the Newfoundland and Labrador Chiropractic Board. In Nova Scotia, chiropractic practice is governed by the Regulated Health Professions Act and the standards of the NSCNR, informed by the Canadian Chiropractic Association Guidelines of Practice.
Chiropractors in Atlantic Canada are authorized to assess and treat conditions related to the spine, joints, and nervous system using spinal and other joint manipulation. The legislation in most provinces defines their authority to perform high-velocity, low-amplitude thrust adjustments, techniques that carry the risks described in detail in Section 4.
Naturopathic Medicine
The regulatory status of naturopathic medicine in Atlantic Canada is a patchwork that differs significantly by province, and patients should understand it before seeking care.
Nova Scotia: Title protection for “Naturopathic Doctor” (ND) has existed since the Naturopathic Doctors Act (SNS 2008, c 5). On May 27, 2026, under the Regulated Health Professions Act (Royal Assent November 2023), naturopathic doctors became Nova Scotia's 22nd fully regulated health profession, now regulated by the Nova Scotia Chiropractic and Naturopathic Regulator (NSCNR), the body formed by transitioning the former Nova Scotia College of Chiropractors. This made Nova Scotia the first Atlantic province to regulate naturopathic doctors.
New Brunswick, PEI, and Newfoundland and Labrador: Naturopathic medicine is not currently regulated. The title “Naturopathic Doctor” does not carry statutory protection, there is no regulatory body, and no formal complaint process is available to patients in these provinces.
For qualified naturopathic doctors, Canadian regulation requires a four-year post-graduate naturopathic medical program accredited by the Council on Naturopathic Medical Education (CNME) and successful completion of the NPLEX (Naturopathic Physician Licensing Examinations).
Acupuncture and Traditional Chinese Medicine
Acupuncture and traditional Chinese medicine (TCM) practice varies by province. Newfoundland and Labrador regulates the profession through the College of Traditional Chinese Medicine Practitioners and Acupuncturists of Newfoundland and Labrador (CTCMPANL), and Prince Edward Island began regulating acupuncture through the College of Acupuncture of PEI (CAPEI) in 2025. In Nova Scotia, practitioners have moved toward regulated status under the Regulated Health Professions Act framework but are not yet regulated, and in New Brunswick acupuncture and TCM are not regulated as a standalone profession, though many practitioners voluntarily adhere to national standards. Some regulated health professionals also perform acupuncture within their existing scopes of practice in all provinces.
Massage Therapy
Massage therapy is regulated in most of Atlantic Canada. New Brunswick, Newfoundland and Labrador, and Prince Edward Island each regulate the profession through a College of Massage Therapists, protect the title “Registered Massage Therapist” (RMT), and provide a college complaint process; it is also regulated in Ontario and British Columbia. Nova Scotia is the exception: massage therapy is not a regulated health profession there, and there is no college to which a complaint can be filed, though practitioners may belong to the voluntary Massage Therapists' Association of Nova Scotia (MTANS). Where massage therapy causes injury, a civil claim in negligence is available in every province; the standard of care is what a reasonably skilled practitioner in the same circumstances would have done.
Other Alternative and Complementary Practitioners
A wide range of practitioners offer services under titles including homeopath, reflexologist, energy healer, Reiki practitioner, iridologist, crystal therapist, and others. None of these are regulated professions in Atlantic Canada. Practitioners may operate with no minimum training requirement, no insurance obligation, and no complaint mechanism beyond the civil courts.
The Regulation Gap: Unregulated Practitioners
The absence of statutory regulation does not eliminate the duty of care or the possibility of a civil claim, but it significantly affects the practical landscape of accountability. Where a practitioner is unregulated:
- There is no college to file a complaint with
- There may be no professional liability insurance, making any judgment difficult or impossible to collect
- The standard of care may be harder to define and require more creative expert evidence
- Marketing claims may amount to misrepresentation if they significantly overstate what a treatment can achieve
Physiotherapy: When Treatment Causes Harm
Physiotherapy is one of the most widely used healthcare professions in Canada. The vast majority of physiotherapy is safe and beneficial. When claims arise, they most often involve one of a discrete set of failure patterns.
The Standard of Care for Physiotherapists
The standard of care for physiotherapists is defined by what a reasonably competent, registered physiotherapist in the same circumstances would have done. It is informed by national competency standards, the standards of practice of the provincial regulatory college, and the clinical literature on evidence-based practice. The more specialized the area of practice, vestibular rehabilitation, post-surgical neurological rehabilitation, pelvic floor physiotherapy, the higher the expected level of competence in that specific area.
Between 30 and 50 percent of claims to the Canadian Physiotherapy Association professional liability insurance program in any given year do not involve physical injury. They involve complaints about professional conduct, communication failures, documentation problems, and boundary violations. Physical injury claims represent the more serious end of the spectrum.
Common Grounds for Physiotherapy Malpractice Claims
Physical injury claims in physiotherapy most commonly arise from:
- Falls during treatment (inadequate supervision or physical support)
- Electrical stimulation errors
- Burns from thermal therapy (heat or cold)
- Injuries from manual therapy techniques applied with incorrect force or at an inappropriate joint level
- Overly aggressive exercise progression causing damage to a healing structure
- Failure to identify a contraindication and modify or discontinue treatment
- Failure to recognize that a patient's condition requires medical referral
Failure to Identify Contraindications and Refer
A physiotherapist has a duty to assess their patient at each visit and to recognize clinical findings that signal a change in condition or that contraindicate the planned treatment. Common scenarios where this duty is breached include:
- Continuing manual therapy on a patient whose presentation has changed in a way that suggests an underlying fracture, spinal pathology, or vascular condition
- Applying traction or mobilization to a patient whose imaging findings, had they been reviewed, would have contraindicated the technique
- Failing to recognize signs of deep vein thrombosis (leg swelling, warmth, calf pain) in a post-operative patient and continuing with treatment that could dislodge a clot
- Not referring a patient whose pain pattern is inconsistent with the musculoskeletal diagnosis and may indicate a more serious underlying cause
A physiotherapist is not required to be a diagnostician, but they are required to recognize when a clinical picture falls outside their scope and to ensure the patient receives appropriate medical assessment.
Electrical and Thermal Treatment Errors
Many physiotherapy treatments involve the application of electricity, ultrasound, laser, heat, or cold to body tissues. When these are applied incorrectly, the consequences can include burns, nerve damage, and cardiac events. A physiotherapist using electrical stimulation must use appropriate parameters, remain in close proximity to monitor the patient's response, and never leave a patient unattended with active electrical equipment. Leaving a patient unattended with active electrical modalities is a clear breach.
Similarly, thermal modalities, hot packs, paraffin wax, ultrasound, can cause burns if applied at incorrect temperatures, for excessive durations, or to patients with reduced sensation who cannot reliably report discomfort. Burns caused by thermal physiotherapy modalities are a recognized form of physiotherapy malpractice.
Manual Therapy Injuries
Physiotherapists trained in manual therapy perform joint mobilization and sometimes manipulation. The risks of these techniques, while generally lower than those associated with high-velocity chiropractic adjustment, are not zero:
- Cervical spine mobilization and manipulation carry risks to vertebral and carotid arteries, the same risks discussed in detail in the chiropractic section
- Aggressive lumbar manipulation carries a risk of disc herniation and, in rare cases, cauda equina syndrome
- Mobilization of a previously undiagnosed fracture can cause displacement or further injury
Physiotherapists performing high-velocity manipulation are expected to apply the same assessment standards and disclosure obligations that apply to chiropractors performing equivalent techniques.
Supervision and Exercise-Related Injuries
A physiotherapist who directs a patient to perform an exercise carries a duty to assess whether the patient can perform it safely; to demonstrate it correctly and verify the patient can perform it; to provide appropriate physical support where needed, particularly for unstable, elderly, or early post-surgical patients; and to recognize and respond to signs of distress during the exercise. A patient who falls and is injured while performing a physiotherapy exercise that was assigned or supervised without adequate attention to their stability has a potential claim.
Documentation and the Non-Physical Dimensions of Claims
Many claims against physiotherapists do not involve physical injury but arise from conduct and professional relationship issues, boundary violations, inappropriate disclosures, dual relationships, and improper communication with third parties. Physiotherapists are also required to maintain accurate and complete clinical records. A physiotherapist whose documentation is incomplete, inconsistent, or fabricated faces not only regulatory consequences but a significantly weakened defence in any civil claim.
Chiropractic: Risks, Benefits, and the Limits of Manipulation
Chiropractic care is widely used across Atlantic Canada for back pain, neck pain, headaches, and joint conditions. For the majority of patients receiving appropriate treatment, chiropractic care is safe. But chiropractic also carries documented and serious risks, particularly associated with manipulation of the cervical spine, and the legal landscape around chiropractic negligence in Canada is well developed.
What Chiropractors Are Authorized to Do in Canada
Chiropractors in Canada are primary care providers authorized to assess and diagnose conditions of the spine, joints, and nervous system and to treat them through spinal and other joint manipulation. The legislation in most provinces, including Nova Scotia's Chiropractic Act, defines their scope to include manipulation that takes a joint beyond its usual physiological range of motion using a fast, low amplitude thrust, a technique known as a high-velocity, low-amplitude (HVLA) adjustment. Chiropractors are not physicians and cannot prescribe medications, but they are primary care providers with an obligation to recognize conditions beyond chiropractic management and to refer patients to physicians when required.
The Most Serious Risk: Cervical Manipulation and Vascular Injury
The most serious and most litigated risk in chiropractic care is stroke caused by arterial dissection following cervical (neck) manipulation. The vertebral and carotid arteries supply blood to the brain. A high-velocity thrust to the cervical spine can cause a tear in the inner lining of either artery, a condition called arterial dissection. When dissection occurs, a blood clot can form at the tear site, travel to the brain, and cause an ischemic stroke.
Some studies suggest a significant association between cervical manipulation and posterior circulation stroke in young patients. The American Heart Association and Canadian neurological societies, including Canadian Stroke Best Practices, have published statements advising practitioners to be aware of this risk. From a legal perspective, the relevant questions in a cervical manipulation stroke case are:
- Did the chiropractor perform an adequate pre-treatment assessment to identify vascular risk factors that should have contraindicated cervical manipulation?
- Did the chiropractor obtain adequate informed consent, including disclosure of the risk of stroke?
- Did the chiropractor perform the manipulation with appropriate technique?
- When symptoms of dissection or stroke appeared, did the chiropractor recognize them and respond appropriately?
A chiropractor who notices a patient developing stroke symptoms during or after a cervical adjustment and does not immediately call 911 has compounded the initial harm with a separate failure to respond. A 2023 CBC news report documents a Winnipeg case in which a patient suffered a right vertebral artery dissection and stroke following cervical treatment; the lawsuit alleges the patient had previously indicated she did not want her neck adjusted, that no informed consent was obtained, and that the treatment caused her stroke.
Cauda Equina Syndrome and Lumbar Manipulation
Cauda equina syndrome (CES) is a rare but catastrophic neurological condition involving compression of the bundle of nerve roots at the base of the spinal cord, causing loss of bowel and bladder control, sexual dysfunction, and permanent paralysis or weakness in the lower limbs. CES is a surgical emergency. Chiropractic lumbar manipulation in a patient with a significant disc herniation can aggravate the herniation, causing it to compress the cauda equina.
The leading Canadian case is Malinowski v Schneider, decided by the Alberta Court of Queen's Bench in 2010 and upheld by the Alberta Court of Appeal in 2012 (2012 ABCA 125). A worker injured his lower back and was treated by a chiropractor; days later he woke unable to feel his legs, and emergency surgery confirmed cauda equina syndrome caused by ejection of the nucleus pulposus of his L3-L4 disc during one of the adjustments. The court found the chiropractor had misidentified the injury, adjusted the wrong level, and failed to disclose the risk of CES. Damages were assessed at $1.33 million, and the risk of CES was found to be a “special or unusual risk” that had to be disclosed even though it was rare.
Failure to Diagnose: When the Real Problem Is Not a Spinal Condition
Chiropractors are primary care providers with a duty to recognize conditions that fall outside chiropractic scope and to refer patients to physicians. Failure to do so, continuing chiropractic treatment for what turns out to be a malignancy, an infection, a fracture, or a vascular condition, is a form of negligence that Canadian courts have recognized. Back pain attributed to a muscle or joint problem may actually reflect:
- A spinal tumour or metastatic cancer
- Vertebral fracture (including pathological fractures in patients with osteoporosis or bone cancer)
- Spinal infection (discitis, epidural abscess)
- Aortic aneurysm presenting with back pain, or kidney pathology
A chiropractor who treats a patient for months without improvement and without considering that the pain may have a sinister cause, and who does not refer for medical evaluation, may be found negligent if the patient eventually receives a delayed diagnosis of a serious condition.
The Critical Importance of Informed Consent in Chiropractic
Informed consent is a central issue in chiropractic malpractice claims. The Supreme Court of Canada established the general framework in Hopp v Lepp (1980) and Reibl v Hughes (1980): practitioners must disclose the risks that a reasonable patient in the patient's specific circumstances would want to know before making a treatment decision. In chiropractic, this requires explicit discussion of the risk of vascular injury and stroke from cervical manipulation (regardless of how rare, because the severity makes it material); the risk of disc herniation and CES from lumbar manipulation; and the alternative treatments available.
Malinowski v Schneider confirmed that a rare but catastrophic risk must be disclosed because its severity makes it a “special or unusual risk.” In an Alberta case, Dickson v Pinder, 2010 ABQB 269, a chiropractor had a patient acknowledge a remote risk of “stroke” without explaining what a stroke was; the court found this inadequate, the mere use of the word without explanation of its meaning and consequences did not constitute meaningful informed consent.
Key Canadian Case Law: Malinowski v Schneider
Malinowski v Schneider remains the most significant Canadian case addressing chiropractic malpractice on the dual grounds of negligent treatment and failure to obtain informed consent. Its key holdings, all upheld on appeal:
- A chiropractor who misidentifies the injured structure and adjusts the wrong level has breached the standard of care
- The standard of care requires a chiropractor to recognize contraindications to treatment at the proposed level before proceeding
- A rare but catastrophic risk is a “special or unusual risk” that must be disclosed
- $1.33 million in damages was assessed for a patient left with permanent bowel and bladder incontinence, sexual dysfunction, chronic pain, and inability to work
Alternative and Experimental Therapies: A Special Category of Risk
Beyond the core professions of physiotherapy, chiropractic, and naturopathic medicine, a wide range of alternative and experimental treatments are legally offered across Canada. Some have an emerging evidence base; others have little or no scientific support. All carry the potential for harm when offered without appropriate patient selection, adequate informed consent, and proper administration.
What Makes a Therapy “Alternative” or “Experimental”
An alternative therapy is one that falls outside the mainstream of conventional evidence-based medicine and is offered as a complement to, or replacement for, conventional treatment. An experimental therapy is one where the evidence of safety and efficacy is still being developed. A practitioner offering such a treatment is held to the standard of care applicable to that treatment within its own discipline, not to the standard of conventional medicine. But the standard of that discipline still requires adequate assessment, informed consent, competent administration, and recognition of when the patient needs conventional medical care instead.
Acupuncture: Risks and Regulated Practice
Acupuncture, the insertion of fine needles at specific points on the body, is one of the most widely used complementary therapies in Canada. When performed by trained practitioners using sterile single-use needles, it is generally safe. Serious adverse events, while rare, do occur and can include:
- Infection from non-sterile needle use, including bacterial infections and, in rare cases, transmission of blood-borne viruses
- Pneumothorax (collapsed lung) from improper needle depth near the chest wall
- Nerve injury from improper needle placement, and retained (broken) needles left in tissue
- Burns from moxibustion, a heat-based technique used alongside acupuncture
A practitioner using non-sterile, reused, or non-single-use needles breaches a fundamental standard of practice. A practitioner who needles in anatomically hazardous zones without appropriate training is also liable for resulting harm.
Intravenous Therapies: High-Dose Vitamin C, Ozone, and Chelation
As discussed in the naturopathic section, intravenous therapies are one of the highest-risk categories of alternative treatment. Ozone therapy, the administration of medical-grade ozone, sometimes through intravenous injection or autohemotherapy, is offered at some Canadian clinics for a range of conditions. The scientific evidence for most of these applications is not established, and the risks include gas embolism if improperly administered intravenously. A practitioner who administers IV ozone without adequate training, proper equipment, or disclosure of the experimental nature of the treatment and its known risks is in a difficult position legally if the patient suffers harm.
Hyperbaric Oxygen Therapy
Hyperbaric oxygen therapy (HBOT), breathing pure oxygen at elevated pressure in a specialized chamber, has established medical applications but is also offered in some Canadian alternative medicine clinics for off-label applications including autism, brain injury, and sports recovery. Risks include oxygen toxicity (seizures, pulmonary damage), barotrauma to the ears or sinuses, fire risk from the oxygen-enriched environment, and contraindications in patients with certain lung conditions or recent surgery. A clinic offering HBOT for off-label purposes is not automatically negligent, but it is required to screen patients for contraindications, operate equipment to established safety standards, and obtain informed consent that addresses both the risks and the experimental nature of off-label use.
Energy-Based and Frequency Therapies
A range of therapies marketed under names including Rife therapy, PEMF (pulsed electromagnetic field therapy), Bioresonance, and various forms of “frequency” or “energy medicine” are offered across Canada with claims that vary from the plausible to the medically unsupported. For devices marketed as medical devices, Health Canada's Medical Devices Regulations apply. Devices sold without the required Medical Device Licence that are represented as diagnosing or treating disease are operating outside Canadian law. A practitioner using unlicensed devices, or making treatment claims that exceed what the evidence supports, may face claims not only in negligence but in misrepresentation.
The Legal Problem of Unproven Treatments
The core legal problem with unproven or experimental treatments is threefold. First, the standard of care within the practitioner's own discipline may not support the treatment at all, making any harm caused by it a prima facie breach of that standard. Second, administering an unproven treatment for a condition that has a proven effective conventional treatment raises questions about whether the patient was adequately informed that conventional options existed and were being foregone, a form of consent failure. Third, where an unproven treatment is used in place of effective conventional care and the patient's condition deteriorates, the practitioner may be liable for the consequential harm of the delayed or foregone treatment, not just the direct harm of their own intervention.
Informed Consent Across All Disciplines
Informed consent is, alongside direct physical negligence, the most commonly litigated issue in physiotherapy, chiropractic, and alternative medicine claims. The legal framework established by the Supreme Court of Canada applies to every healthcare practitioner in the country, regardless of their designation.
The Duty to Disclose in Non-Physician Healthcare
The Supreme Court of Canada established the current standard for informed consent in two companion decisions: Hopp v Lepp (1980) and Reibl v Hughes (1980). These decisions held that a practitioner must disclose the information that a reasonable patient in the patient's specific circumstances would want to know before making a decision to proceed with treatment. This standard applies to chiropractors, physiotherapists, and naturopathic doctors in the same way it applies to physicians and surgeons. The Alberta Court of Appeal confirmed in Malinowski v Schneider that rare but catastrophic risks are “special or unusual risks” that must be disclosed even if they are unlikely.
What Must Be Disclosed
Before performing any treatment with material risk, a practitioner must disclose:
- The nature of the proposed treatment
- The material risks of that treatment, including rare but serious risks such as stroke from cervical manipulation or CES from lumbar manipulation
- The expected benefits and the realistic likelihood of those benefits
- Reasonable alternatives to the proposed treatment
- The consequences of not receiving any treatment
In alternative and experimental medicine settings, there is an additional disclosure requirement: if a treatment lacks established evidence of efficacy or is being offered for purposes not supported by published evidence, this must be disclosed. A patient who is not told that a treatment is experimental cannot give truly informed consent to it.
When a Signed Consent Form Is Not Enough
Many clinics use standardized consent forms that list potential risks. The existence of a signed form does not automatically mean informed consent was obtained. Courts have consistently held that a form that lists a risk by name without explaining what it means does not constitute adequate disclosure; that a form handed to a patient to sign on the day of their first treatment, without opportunity to read and consider it, may not represent meaningful consent; and that a form does not substitute for a conversation in which the practitioner assesses what the patient has understood. The test is not whether the patient signed a document; it is whether a reasonable patient in their circumstances, properly informed, would have consented to the treatment.
The Chiropractic Stroke Disclosure Problem
How Do I Know If My Practitioner Was Negligent?
The Standard of Care in Each Discipline
The standard of care is discipline-specific. A physiotherapist is not held to a physician's standard; they are held to the standard of a competent physiotherapist. A chiropractor is held to the standard of a competent chiropractor in the same specialty and circumstances. This means that in any malpractice claim against a non-physician healthcare provider, the expert evidence must come from a practitioner with equivalent training and experience. A physician testifying about what a competent chiropractor should have done is generally not the right expert; a qualified chiropractor who practices in the same area is.
Distinguishing a Known Risk from a Preventable Error
As in all healthcare malpractice, the central question is whether the harm was the result of a known and unavoidable risk of the treatment, properly disclosed and consented to, or whether it was the result of a practitioner's departure from the standard of care. A stroke that occurs following cervical manipulation in a patient who was properly assessed, found to have no vascular risk factors, given complete informed consent, and treated with appropriate technique may be a tragic but non-negligent outcome. A stroke that occurs following manipulation in a patient who was not assessed, was not given meaningful disclosure, and whose consent was obtained through a form they were handed to sign without explanation is a very different situation. This analysis requires expert evidence.
The Role of Expert Evidence
Expert evidence is required in virtually all malpractice claims against non-physician healthcare providers. The expert must be qualified in the same or an equivalent discipline and specialty; have direct experience in the area of practice at issue; be able to articulate the standard of care applicable to the defendant at the time of the alleged negligence; express an opinion on whether the defendant's conduct met that standard; and address whether any breach caused the patient's harm. For chiropractors, this means a qualified chiropractor with appropriate practice experience; for physiotherapists, a qualified and practicing physiotherapist; for naturopathic doctors, a qualified and experienced ND.
When the Negligence Is a Failure to Refer
Failure to refer is a distinct and actionable form of negligence across all of these professions. The duty to refer arises when the patient's condition is beyond the scope of the treating practitioner; when the clinical picture suggests a condition requiring medical assessment; when the patient is not responding to treatment as expected, raising concern about the diagnosis; or when a condition requires urgent or emergency medical care. A chiropractor, physiotherapist, or naturopath who continues to treat a condition that requires medical evaluation, delaying an accurate diagnosis and appropriate treatment, may be liable not only for any direct harm but for the consequential harm of the diagnostic delay.
Will a Practitioner or Clinic Acknowledge If Something Went Wrong?
In most cases, not directly. The duty of candour that applies to physicians in hospital settings also applies in principle to regulated non-physician healthcare providers, but the practical reality differs between professions and settings:
- Chiropractors are defended by their professional liability insurers, who advise caution around admissions of fault.
- Physiotherapists are defended by provincial liability insurance programs or private coverage and are similarly advised to refrain from admissions while a matter is under investigation.
- Naturopathic doctors in regulated provinces carry CAND-recommended professional liability insurance and receive equivalent advice.
- Unregulated alternative medicine practitioners may have no insurance, no legal support, and no structured process for acknowledging adverse events.
Where the practitioner is regulated, you may file a complaint with their regulatory college. A complaint can run alongside a civil claim, can produce independent findings, and may result in the practitioner being sanctioned, suspended, or losing their licence. Regulatory college contact information by province and profession is provided in Section 2 of this guide.
What Are the Limitation Periods for Filing a Claim?
General Limitation Periods in Atlantic Canada
Nova Scotia
The Limitation of Actions Act (SNS 2014, c 35) provides a basic period of 2 years from discovery, with a 15-year ultimate period.
New Brunswick
The Limitation of Actions Act (SNB 2009, c L-8.5) provides 2 years from discovery and a 15-year ultimate period.
Prince Edward Island
The Statute of Limitations (RSPEI 1988, c S-7) provides a 2-year period for personal-injury and negligence claims (s. 2(1)(d)) with discoverability applied by courts.
Newfoundland and Labrador
The Limitations Act (SNL 1995, c L-16.1) provides 2 years from discovery.
The Discoverability Principle
The limitation clock typically begins when the patient knew or reasonably ought to have known that an injury occurred, that it may have been caused by the practitioner's act or omission, and that a legal claim was potentially available. In cases involving alternative medicine harm, this principle is particularly relevant. A patient who was told by their naturopath or chiropractor that a worsening symptom was a “healing crisis” or a normal response to treatment may not have recognized that they had been harmed, and that the harm was caused by the treatment, until they sought conventional medical assessment. The date of that assessment, not the date of the original treatment, may be the discoverable date.
Complaints to Regulatory Colleges
Filing a complaint with a regulatory college does not extend a civil limitation period and is not a substitute for a civil claim. However, the findings of a college investigation, including that a practitioner was found to have breached professional standards, can be powerful supporting evidence in a civil proceeding. A college complaint and a civil claim are distinct and can proceed simultaneously; there is no requirement to wait for one to conclude before commencing the other.
What Are the Damages and Compensation Amounts Typical for These Claims?
Types of Damages
Non-Pecuniary General Damages (Pain and Suffering)
In chiropractic stroke and CES cases, the most catastrophic outcomes in this category, non-pecuniary damages reflect severe and permanent disability. A patient left with hemiplegia, permanent bowel and bladder incontinence, chronic pain, and sexual dysfunction (as in Malinowski) is entitled to significant compensation. In physiotherapy and naturopathic cases with less catastrophic outcomes, a burn from electrical equipment, a disc aggravation, or an adverse reaction to IV therapy, non-pecuniary damages will be proportional to the severity and permanence of the harm.
Pecuniary Special Damages
These cover out-of-pocket losses including medical treatment for the harm caused (emergency care, specialist follow-up, surgery, ongoing rehabilitation); the costs of undoing the harm caused by incorrect treatment; and medications and assistive devices.
Future Care Costs
In catastrophic cases such as stroke or CES, future care costs are often the largest component of damages. A young person left with permanent neurological disability following a chiropractic stroke may require personal support services, equipment, home modifications, and ongoing medical care for decades.
Loss of Income and Earning Capacity
Where the injury has affected the patient's ability to work, lost income and impaired future earning capacity are recoverable.
The Cap on Non-Pecuniary Damages
Canada's Supreme Court 1978 damages trilogy established a cap on non-pecuniary damages (pain and suffering), currently approximately $430,000 to $450,000 in the mid-2020s. Future care, lost income, and other pecuniary losses are not capped. In serious cases, particularly chiropractic stroke or CES resulting in permanent disability, total awards can be very substantial. The Malinowski case resulted in total damages of $1.33 million in 2010 dollars.
Fatal Cases
Where a patient dies as a result of negligent treatment, a fatal stroke following cervical manipulation, a fatal adverse reaction to IV chelation therapy, or death from a condition that went undiagnosed while the patient pursued alternative treatment, the family may have claims under the applicable provincial fatal accident legislation. (See the Fatal Accident Claims Guide in this series for full details.)
How Much Does It Cost to Pursue a Claim?
Contingency Fee Arrangements
Claims against physiotherapists, chiropractors, and alternative medicine practitioners in Atlantic Canada are generally handled on a contingency fee basis. No fee is charged unless the case succeeds. Contingency fees typically range from 25% to 33% of the final recovery and must be set out in a written agreement.
Disbursements and Expert Costs
Expert evidence requirements in these cases are discipline-specific. Disbursements typically include:
- Expert reports from qualified practitioners in the relevant discipline (chiropractor, physiotherapist, naturopathic doctor as applicable)
- Neurology or vascular surgery expert reports in stroke or nerve injury cases
- Neurosurgery expert reports in CES cases
- Rehabilitation and life care planning reports in catastrophic injury cases
- Medical record retrieval and court filing costs
Most firms working on contingency advance these costs to be recovered from the settlement or judgment. Confirm this in writing before retaining counsel.
What Happens If You Lose?
As in all Canadian civil litigation, an unsuccessful party may be ordered to pay a portion of the successful party's legal costs. This adverse costs risk is a genuine consideration in deciding whether to proceed to trial or accept a settlement. A good lawyer will address this risk frankly at each decision point.
How Long Does a Case Typically Take?
Stages of a Claim
Stage 1: Initial Consultation and Case Evaluation (1 to 3 months)
The lawyer reviews available records. In chiropractic cases involving a stroke, neurological imaging (MRI/MRA) from the acute hospitalization is a key document that must be obtained early.
Stage 2: Record Collection and Expert Review (6 to 18 months)
All treatment records, consent forms, incident documentation, and medical records from any resulting hospital care are gathered. Discipline-specific expert reports are obtained on the standard of care and causation.
Stage 3: Issuing the Statement of Claim
Once expert evidence supports the claim, proceedings are formally commenced.
Stage 4: Pleadings and Discoveries (1 to 2 years)
Both parties exchange documents and examine witnesses under oath. In chiropractic cases involving stroke, causation, whether the manipulation caused the dissection or whether it was already in progress, is typically the most contested area of discovery and expert testimony.
Stage 5: Mediation and Negotiation
Most cases in this category resolve by settlement after discoveries. Catastrophic injury cases involving permanent disability are often settled rather than tried because the quantum of damages is predictable and both sides have incentive to resolve without the cost and unpredictability of trial.
Stage 6: Trial (if necessary)
Trials in chiropractic stroke or CES cases typically run from two to four weeks.
When Settlements Are Most Likely
Cases involving clear liability, documented failure to disclose the stroke risk, a clear temporal connection between manipulation and stroke onset, permanent disability, tend to settle before trial. Cases where causation is disputed (the defendant argues the dissection pre-existed the manipulation) are more likely to require expert evidence at trial and to take longer to resolve. From initial consultation to resolution, these cases typically take three to six years.
Things to Consider When Choosing a Lawyer for a Claim in This Area
Experience in non-physician healthcare malpractice
Ask directly whether the lawyer has handled claims against chiropractors, physiotherapists, or naturopathic and alternative medicine practitioners. The discipline-specific standard of care analysis, the type of experts required, and the regulatory landscape are all meaningfully different from physician malpractice practice.
Access to discipline-specific expert witnesses
You cannot successfully establish the standard of care in a chiropractic case without a qualified chiropractic expert. Ask whether the lawyer has established relationships with expert practitioners in the relevant field. This is one of the most important practical differences between lawyers experienced in these cases and those who are not.
Understanding of informed consent in this context
Given that informed consent failure is the most commonly successful ground in chiropractic malpractice claims, and a significant issue in alternative medicine claims, your lawyer should understand how the Hopp v Lepp / Reibl v Hughes framework applies to non-physician practitioners.
Sensitivity to the context
Patients who sought alternative or complementary care often did so because they were seeking something different from conventional medicine, often in the context of a condition that has been challenging to manage. The right lawyer will understand this context without judgment and will help you assess your claim fairly.
Resources to sustain the litigation
Expert reports in multi-specialty cases (chiropractic, vascular surgery, neurology, rehabilitation) can represent significant combined disbursements. Confirm that the firm has the capacity to advance these costs over the course of a multi-year case.
Written fee agreement
The contingency fee, disbursement handling, and adverse cost risk should all be clearly set out in writing before you sign.
