Dr. John Gannage, MD, CCFP

Hi, I’m Dr. John Gannage, founder of Markham Integrative Medicine. My medical background is within the scope of Family Practice, a specialty that ideally emphasizes continuity of care, comprehensive care, health promotion and prevention. Recognizing the limitations of my conventional training, particularly in regard to supporting the “chronically unwell” and today’s epidemics, I began the scientific process of searching and observing outside of standard medical training. I support strongly the concept of Integrative Medicine, which incorporates aspects of Complementary Medicine adjunctively with Conventional Medicine. I offer, therefore, a holistic approach with specific emphasis on lifestyle counselling, nutrition and nutritional therapy, mind-body medicine and homeopathy, areas in which I have special training.

Dr. John Gannage, holding an active medical licence in good standing with the College of Physicians and Surgeons of Ontario (CPSO), and as a longstanding practitioner of CAM, is considered an expert in the CAM field. Dr. Gannage is regularly requested to offer his opinion regarding current standard of care and best practices within his professional domain.  He is a Peer Assessor for the CPSO, works on behalf of the Investigations, Resolutions and Complaints Committee, and has acted as Preceptor for fellow physicians as part of the CPSO’s self-regulating governance and education initiatives. His practice has “GP Focused Practice” designation from the Ministry of Health and OMA, which allows Dr. Gannage to provide OHIP services without economic penalty to a rostered patient’s primary care physician.

Dr. Gannage founded and is currently the Medical Director of Markham Integrative Medicine, where he has been emphasizing prevention and treatment of chronic disease through nutrition, detoxification, immune sysem modulation and reduction of oxidative stress since 1998. In addition, Dr. Gannage has been administering Chelation Therapy since 1999, in which he is specifically trained, and has also received training in Oxidative Medicine and Lipid Exchange Therapy. He is a Defeat Autism Now clinician, and in 2012 completed Modules 1 and 2 of proposed Fellowship training in MAPS, the Medical Academy for Pediatric Special Needs.

Dr. Gannage has special focus in assisting children and families affected by developmental issues, including autism, using biomedical therapy. Still, the majority of Dr. Gannage’s practice is for chronic illness and conditions among adults, for which he has developed specific protocols from a functional medicine perspective.

Dr. Gannage graduated from University of Toronto medical school in 1990 and completed his residency in Family Medicine at the University of Ottawa. At the University of Toronto he was recognized with the Medical Society Award for Outstanding Contribution to the Faculty of Medicine. He earned Honours in 3 years at University of Toronto in the Faculty of Medicine and was President of the Men’s Medical Athletic Association, while also serving on Student Council.  Dr. Gannage served as Medical Director of Meadowbrook Sport Medicine and Rehabilitation Clinic in Markham, while also operating his Family Practice.  His work in Sport Medicine was valuable in galvanizing Dr. Gannage’s interest in holistic and collaborative approaches to health.  In 2000 Dr. Gannage was voted Markham’s Best General Practitioner.   He has obtained two diplomas in Homeopathy, and studied extensively in the fields of Clinical Nutrition and Functional Medicine.

Dr. Gannage has membership in MAPS, the American College for Advancement in Medicine (ACAM), the Canadian Society of Orthomolecular Medicine (CSOM), the Ontario Medical Association (OMA), and its Section on Complementary and Integrative Medicine, and the Canadian Association of Physicians for the Environment (CAPE).

Dr. Gannage was a principal investigator for TACT (the Trial to Assess Chelation Therapy), enrolling Canada’s first participant. Dr. Gannage had been appointed to the Medical Advisory for Mindful, a charitable organization and network that provided information on the importance of diet, nutrition and lifestyle in optimizing children’s mental health.

In 2014, “Integrative Medicine for Children’s Mental Health” was launched. This program was researched, written and presented by Dr. Gannage at 3 Canadian Universities across the country. The professional seminar, co-sponsored by Mindful and CSOM, was recognized for accreditation by the College of Family Physicians of Canada. Dr. Gannage continued the professional seminars  in 2015 and 2016, in Toronto, Vancouver, Calgary and Hamilton. The program’s objective is to provide an evidence-based approach to ASD, ADHD and other mental health conditions in children to health professionals, including medical doctors, with clinical management guidelines and research outlined. Dr. Gannage emphasizes nutrition and environmental factors, and explains the relationship of the gut-microbiome-brain axis, oxidative stress, immune dysregulation and environmental toxicants to mental health disorders.

Dr. Gannage regularly educates the community and other practitioners through public presentations, has appeared on radio, lectured at ACAM’s biannual medical conference and written numerous articles for publication.
