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.

We're a diagnostic clinic that examines the changing states of your heart and your blood flow. Our procedures involve injecting a small amount of radioactive material that will allow doctors to see how the heart contracts and dilates and how the blood flows, both when you're under stress and are at rest.
Using radioactive tracers, we are able to see how the heart is working, not just how it looks. Our scans are three-dimensional pictures of a moving, beating heart that can be observed at many different angles and views. This is a non-invasive diagnostic tool which allows your doctor insight into your heart health.
Patients are most often referred to us because they experience chest pain or are at risk because of their family history or smoking, diabetes, high blood pressure and high cholesterol.
You might also be referred to us to check for coronary artery disease and to check how a heart procedure such as angioplasty or bypass surgery has improved your health. We might also check to see if your heart is healthy enough for surgery, to determine the effects of chemotherapy on your heart and to find out how well your heart is pumping. Our tests include:
Pharmacological and exercise stress testing, using radioactive tracers:

You will be contacted with information about your first appointment.
Please bring the following to your appointment. Not all of these items may be needed for your appointment. Our clinic or your referring doctor will let you know what you must bring.
Please arrive 15 minutes before your appointment.
When you arrive, you will sign in with the receptionist. You will need your health card (OHIP card) to sign-in. If you do not have an OHIP card, please bring another form of government-issued photo ID, such as a driver’s license or passport.
You may be given a Measuring Health Equity Questionnaire to fill out. This form contains questions about your background. We collect this information to find out who we serve and what unique needs you may have. The form is voluntary and you can choose ‘prefer not to answer’ to any or all questions. However, the information you choose to give us will help us improve the quality of care for you and others.
First appointments take longer than follow-up appointments. Your first appointment can take 2 hours or more. Follow-up appointments usually take 15 to 30 minutes. We do everything we can to stay on time but sometimes unforeseen circumstances may delay your appointment.
At the end of your first appointment, the nurse or doctor will give you a contact list for your health care team. If you don’t get a contact list, feel free to ask for it.
After every appointment, a member of your health care team will tell you about your next visit. Be sure you understand what is going to happen next. For example, know the time and place of your next visit or if someone will call you with this information.
If you are unsure about what your next steps are, don’t be afraid to ask a member of your team. We are here to help you.
We understand that reaching us by phone can sometimes be difficult. Often our phone lines are busy or are turned over to the message centre so our staff can prepare for clinic visits or help other patients. We make every effort to return your call within 24 hours. Our staff will try to reach you 2 times. If we are not able to reach you directly you may need to call us again.
