Here is the reply I received back from the CVO (College of Veterinarians of Ontario):
Non-Conventional Therapies in the Practice of Veterinary Medicine:
The Veterinarians Act currently requires that any individual providing animal care services that relate to veterinary medicine must provide these services under the delegation and supervision of a veterinarian. However, it is clear that certain non-conventional therapies are in the public domain. These lower risk activities are being provided to animals by non-veterinarians upon client request and without veterinary oversight. It is still encouraged that providing these services should be coordinated with a veterinarian in the interest of the animal’s health. The College does not regulate third party businesses. Where non-veterinarians provide non-conventional therapies, they must not hold out to be practicing veterinary medicine. The acts of diagnosis, prognosis, prescribing, major surgery and acupuncture are the practice of veterinary medicine.
Then a few links to related legislature, including this one which was just signed into royal assent on June 6, 2024: https://www.ontario.ca/laws/statute/24v15#BK152
The restricted acts are listed in Schedule 1 (you can click on it in the top menu to take you directly to it).
So, I guess nothing is being done or will be done if the CVO does not regulate third party businesses. I don’t understand how they say they don’t, but then also say you can’t practice veterinary medicine without a license - so who is enforcing this?
I did email back asking for a clarification on the nerve release, and whether it fell under prognosis since the example screenshot I sent them says it can alleviate a whole list of conditions. Waiting to hear back.
