Our UHN programs and services are among the most advanced in the world. We have grouped our physicians, staff, services and resources into 10 medical programs to meet the needs of our patients and help us make the most of our resources.
University Health Network is a health care and medical research organization in Toronto, Ontario, Canada. The scope of research and complexity of cases at UHN has made us a national and international source for discovery, education and patient care.
Our 10 medical programs are spread across eight hospital sites – Princess Margaret, Toronto General, Toronto Rehab’s five sites, Toronto Western – as well as our education programs through the Michener Institute of Education at UHN. Learn more about the services, programs and amenities offered at each location.

The exercise thallium test gives us information about how your heart is working. We'll watch you closely as you exercise on a treadmill so that we can measure how well your heart handles this kind of activity.
The test is very useful in checking whether there are any blocked arteries, how your heart treatment is progressing and if your heart is strong enough for surgery. It will also tell us if any recent heart surgery (like a bypass or angioplasty) has done its job and is improving your health.
