When the military hospital closed after the War of 1812, York was left without a hospital. Surplus funds raised by the 'Loyal and Patriotic Society of Upper Canada' for those who suffered as a result of the war, were used to build a hospital at the northwest corner of King and John Streets. A two story red brick building for 100 patients was completed by 1824, but was immediately requisitioned for the Legislative Assembly, whose building had been destroyed by fire. It was opened as a hospital in 1829, and became the Toronto General Hospital in 1834. From 1831, Dr. John Rolph used the hospital for teaching medical students, and students from King's College and Trinity College were also taught here. During the Cholera Epidemic of 1847 wooden sheds were built to the north and it became a fever hospital, accommodating 798 patients.
