Lia Sonnenburg

I began post-secondary studies in the field of Health Sciences at the University of Western Ontario. Five years later I graduated with a Degree in Health Sciences and Biology but my academic appetite was not yet satisfied. I knew exactly that I wanted to work with people in the realm of healthcare – to make their goals attainable. I soon began my studies at the Canadian College of Naturopathic Medicine in Toronto and graduated in 2010. During this time I was heavily involved both within and outside of the school community.  I have been working in the Collingwood area, seeing patients since January of 2010.


It hasn't all been smooth sailing since then however.  Upon graduation, I wrote and passed all those grueling board exams which welcome you into the regulated profession and I became a fully licensed and registered Naturopathic Doctor in the province of Ontario.  But in 2015 our regulatory college moved under the RHPA (Regulated Health Care Practitioners Act) which meant many changes, more examinations, inspections, and busy-work. Although the timing was not fabulous (with two boys under the age of 4 at home) - I managed to pass the first round of the prescribing and therapeutics examinations in 2015 allowing me to continue to practice IV therapy and now prescribe certain restricted therapeutics (bioidentical hormones, thyroid medications, Vitamin D3, etc).  I wanted to ensure my patients had access to my entire scope and that they were able to continue their journey. I believe this added push has made me a better doctor and kept me up-to-date on the therapeutic side of things. Mostly, however, I like the day-to-day stuff where I get to meet wonderful people and help them improve their health and “Be Well”.


I'm a member of the Canadian and Ontario Associations of Naturopathic Medicine and the Oncology Association of Naturopathic Physicians.

Why Naturopathic medicine was the right fit for me...

A large portion of my undergraduate studies involved health policy courses and as I learned about the way the health-care system works in Canada, I became less enchanted by the profession I first sought out to be a part of. I wanted to practice medicine from an individualized and grassroots approach – recognizing that every one of us is different and unique.


I tagged on a couple extra semesters to complete a secondary focus in biology and a year of studies abroad at the University of Otago in New Zealand.


I grew up in a european family where home-remedies ruled over visits to the doctor. My mother was a large advocate of the ‘you are what you eat’ principle and every meal that she served (although frustratingly labour intensive) was made from garden fresh ingredients, as free of chemicals as possible. It was a philosophy that simply ‘was’ and as a result I think my health has been fairly ‘unremarkable’ (that being medical terminology for great).


I found Naturopathic medicine through the stories of immediate family and it resonated with the way I wanted to practice medicine: do no harm, cooperate with nature, find the root cause, treat the individual and educate.

I’ve further grown to love my vocation not only through seeing the major changes in the lives of the people that come in and out of the clinic every day but also in that of my kids.  The body truly is remarkable and if you give it what it needs, things work!
