Animal Chiropractic in Canada:
A Growing and Unregulated Sideline

Across Canada, chiropractors — and in some cases veterinarians — have begun offering spinal "adjustments" to dogs, cats, horses, and other animals. The claims are large. The evidence base is thin. The regulatory oversight is minimal. ChiroWatch documents the practitioners, the promoters, and the unanswered questions.

Background: What Is Animal Chiropractic?

Animal chiropractic — also called veterinary chiropractic or zoological chiropractic — applies the core chiropractic premise of spinal "subluxation" to non-human patients. Practitioners claim that misalignments of the vertebrae interfere with the nervous system and that manual adjustments restore normal function, relieve pain, and improve mobility in dogs, cats, horses, and other animals.

The concept is not new. The American Veterinary Chiropractic Association (AVCA) has offered certification since the mid-1980s, and an Ontario-based instructional body — the Veterinary Chiropractic Learning Centre — has trained practitioners in Canada for decades. In the United States, the Options for Animals college in Illinois has been a primary credential-granting institution.

Key regulatory point: In Ontario, animal chiropractors are not regulated under the Regulated Health Professions Act. Unlike human chiropractic — governed by the College of Chiropractors of Ontario — animal chiropractic has no dedicated licensing body. Some practitioners hold dual credentials (both AVCA certification and either a chiropractic or veterinary licence); others do not. Whether a veterinary referral is required before treatment varies by province and has been disputed within the profession itself.

The Subluxation Premise Applied to Animals

The foundational claim — that spinal "subluxations" cause systemic disease and that adjustments correct them — has never been validated in human chiropractic to the satisfaction of mainstream medicine. Applying this framework to animals adds a further layer of difficulty: the animal cannot report symptoms, cannot consent, and cannot describe whether treatment is helping or hurting.

Practitioners acknowledge this implicitly. As one Canadian animal chiropractor told the Sault Star in 1996, diagnosing animals requires "observing the animal's posture and gait" and "feeling for it." A 2013 profile in The Tribune (Welland) noted that a veterinarian at Main West Animal Hospital, Welland, had "seen dramatic improvements" in animals with hip dysplasia — though no controlled data was cited.

The placebo problem is acute in veterinary settings. Owners who invest time and money in treatment are highly motivated to report improvement. The animal's response to handling, warmth, and attention from a practitioner may itself produce apparent behavioural change. None of the newspaper profiles reviewed for this page cited peer-reviewed evidence for the treatments described.

Canadian Practitioners Documented by ChiroWatch

The following practitioners were identified through Canadian newspaper coverage spanning 1996 to 2018. ChiroWatch makes no claim that this list is complete. Inclusion does not imply disciplinary findings; it reflects documented public promotion of animal chiropractic services.

Dr. Judy Williamson
Calgary, Alberta

A licensed animal chiropractor described as treating dogs and horses in Calgary. Reportedly dedicated one day per week to four-legged patients, leaving her human practice behind. Described treating a 12-year-old Labrador cross with neck problems.

Kawartha Lakes This Week, June 21, 2018; December 27, 2018

The MediaArt / Marchfield Farm Event (2004)

On April 18, 2004, an event titled "Experts offer alternative therapies for animals" was held at Marchfield Farm, 3510 Bowen Rd., approximately one kilometre east of South Morningstar Road in Stevensville, Ontario. The event was hosted by MediaArt, an alternative health publisher. More than a dozen experts in alternative therapies were scheduled to offer live demonstrations and "meet-the-experts opportunities."

Therapies advertised included acupuncture, light infusion, chiropractic, SCENAR therapy, massage, and reiki. Non-invasive diagnostic assessments were also promised, along with an "animal communicator" who would discuss the causes of behavioural issues and "talk to an animal." Contact was listed through Rebecca Proulx at Marchfield Farm and Lori D'Ascanio.

Note: MediaArt's involvement is worth flagging. Events combining veterinary chiropractic with animal communication, reiki, and light infusion are characteristic of the broader alternative health ecosystem that ChiroWatch monitors. The bundling of evidence-free modalities under a single promotional banner makes individual claims harder to scrutinize and lends unearned credibility to each through association.

The Regulatory Gap

Animal chiropractic in Canada occupies an unusual regulatory position. Unlike human chiropractic — which is a self-regulated health profession under provincial legislation — animal chiropractic has no equivalent regulatory framework. Practitioners may hold AVCA certification, but this is a private credentialling body, not a government-authorized college.

In Ontario, the College of Veterinarians of Ontario (CVO) governs veterinary practice. Whether a chiropractor who is not a licensed veterinarian may legally treat animals without a veterinary referral is not consistently enforced. Dr. Langdon's 2006 advertisement in the Niagara Falls Review stated explicitly: "In accordance with our Provincial Standards, a veterinary referral is not required before Dr. Langdon can examine and treat your animal." This claim should be read in light of the CVO's own guidelines, which have evolved over time.

Dr. Aron Bhan, a veterinarian by training, is in a different regulatory position than a chiropractor offering animal services — but in neither case does an independent body audit outcomes, investigate complaints, or publish discipline records for animal chiropractic specifically.
