Medicine and healthcare facilities have become essential parts of modern life, providing treatment, examinations, and preventative care. In Toronto, hospitals and clinics are now an integral part of the cityscape. However, there was a time when medicine was less advanced, and healthcare institutions were only beginning to emerge. Today, we’ll explore the story of Toronto General Hospital (TGH), the city’s principal teaching hospital. Discover its fascinating history and development on toronto1.one.
From Barn to Leading Hospital
The origins of Toronto General Hospital date back to 1812, when it operated out of a modest barn serving British Army soldiers during the war. After the war ended, this military hospital was converted into York General Hospital. In 1820, construction began on a new building for the facility, which opened nine years later.
In 1855, a new hospital building was constructed based on designs by architect William Hay. Over the years, the hospital continued to grow and expand. By 1913, the hospital relocated again, this time to College Street, where it underwent modernization and innovation.

Medicine at Its Finest
The 2000s marked a significant period of reconstruction for TGH. This ambitious project aimed not only to build new facilities but also to create state-of-the-art environments for delivering advanced medical care. The hospital focused on specialties like cardiology, neurosurgery, and organ transplantation.
By 2017, Toronto General Hospital had become the largest organ transplant center in North America, performing 639 transplants that year alone. This included:
- 167 lung transplants
- 195 liver transplants, 39 of which were from living donors
- 202 kidney transplants, 65 of which involved living donors
- 34 heart transplants
TGH is renowned for its groundbreaking achievements, including the world’s first single and double lung transplants in 1983 and 1986, respectively. In 2015, surgeons performed the first-ever triple-organ transplant (lungs, liver, and pancreas) on a 19-year-old patient.
Scientific Achievements at TGH
Toronto General Hospital houses the Peter Munk Cardiac Centre (PMCC), one of Canada’s leading open-heart centers. Additionally, as a teaching hospital affiliated with the University of Toronto Faculty of Medicine, TGH plays a vital role in educating future healthcare professionals. For nine consecutive years, TGH ranked first in Canada’s research hospital rankings, as reported by Research Infosource.
Over its history, TGH has made significant scientific contributions, including:
- 1922: The first clinical use of insulin.
- 1935: The first clinical use of the anticoagulant heparin.
- 1950: The first use of an external cardiac pacemaker during open-heart resuscitation.
- 1955: The world’s first successful heart valve transplant.
- 2016: Canada’s first hand transplant.
Toronto General Hospital is a leader in Canadian healthcare, continuously evolving and incorporating cutting-edge technologies. Its advancements in cardiology and organ transplantation stand out as prime examples of its commitment to excellence. As part of the University Health Network (UHN), TGH also provides outstanding educational opportunities for aspiring medical professionals.
