Melissa Lem is a Toronto family physician who also works in rural and remote communities across Canada. Her first job was as a small-town emergency room, obstetrics and acute care doctor in northern British Columbia before she was drawn back to the bright lights and big city.

A lifelong nature enthusiast, her regular writings on health and the environment have been featured by Evergreen and the David Suzuki Foundation. She can sometimes be found playing doctor - and other roles - on film sets around town, and in-house for the Canadian Opera Company. Dr. Lem is actively involved in medical education and holds a faculty appointment with the Department of Family and Community Medicine at the University of Toronto.
