Dr. Mariia Tanasyshyn, ND, is a licensed Naturopathic Doctor in Ontario with a rare and valuable dual background. Before completing her naturopathic medical training at the Canadian College of Naturopathic Medicine, Dr. Mariia earned her Doctor of Medicine (MD) degree in Ukraine, where she trained extensively in internal medicine. Although she is not practicing as a medical doctor in Ontario, her medical education provides a deep understanding of complex health conditions and allows her to interpret symptoms, labs, and diagnoses through a uniquely integrative lens.
Now fully licensed as a naturopathic doctor (ND) under the College of Naturopaths of Ontario (CONO), she offers evidence-informed, patient-centered care that blends the strengths of both medical and naturopathic approaches. Her visits are not covered by OHIP, but may be reimbursed through extended health insurance like other naturopathic services.

Patients often seek out Dr. Mariia when they are looking for health care answers and support. These patients often don’t have access to a family doctor, or they are receiving inadequate care from their GP.

Your Doctor: Meet Dr. Mariia
Outside of the clinic, Dr. Mariia is guided by a deep curiosity about lifelong learning and the ways culture, daily habits, and personal rituals shape our well-being. She loves noticing how small routines—like a morning walk or a shared conversation—can shift how we feel. She’s also inspired by the way people create meaning through their daily lives, and how those moments influence overall health.
Nature is one of her favorite places to recharge. You’ll often find her hiking, walking along the water, or tending to her ever-growing collection of houseplants. One of her proudest plant-moments was growing an avocado tree from a single seed—an experience that reflects her clinical philosophy: when you understand the root of something and give it the right conditions, meaningful growth becomes possible.
Fluent in English, Ukrainian, and Polish, Dr. Mariia values connection and community. She cherishes time with family and friends, seeks out local cafés, and enjoys discovering new places across Ontario.
At her core, Dr. Mariia is motivated by a genuine commitment to helping people feel understood, supported, and empowered in their health. This belief shapes not only her clinical approach but also the way she moves through her everyday life.
