The Cottage Sanatorium in Gravenhurst, Muskoka, was the first one in Canada. Tuberculosis patients breathed plenty of Muskoka’s clean, pine-scented air, as treatment consisted of spending the best part of every day outdoors, no matter the weather. In winter, patients would be wrapped in layers of woolens or furs, and then in a dozen blankets before their beds or "cure chairs" were wheeled onto verandas.
