PLEASE NOTE: CARO cannot provide patients with the names of physicians providing care to patients. The Colleges of Physicians and Surgeons in most Canadian provinces and territories maintain a website for patients to find a physician by specialty. A list of these governing bodies is available on the Federation of Medical Regulatory Authorities of Canada’s website.
