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.

Ways You Can Help
Being touched by illness affects us in different ways. Many people want to give back to the community and help others. At UHN, we welcome your contribution and offer different ways you can help so you can find one that suits you.
The Newsroom is the source for media looking for information about UHN or trying to connect with one of our experts for an interview. It’s also the place to find UHN media policies and catch up on our news stories, videos, media releases, podcasts and more.
Patients will be screened for COVID-19 in their clinics. Essential Care Partners, contractors, suppliers and anyone else entering UHN will be expected to self-screen at the hospital entrance. Our screening, masking and visitor vaccination requirements continue to be stronger than those in other public settings because UHN cares for some of the most vulnerable patients.
On the day of your visit, use our COVID-19 Self-Screening Tool before arriving to get through our screening process as smoothly as possible.

Past outbreak information
How do you define an outbreak?
The definition of a COVID-19 outbreak in a hospital is set by the province of Ontario. It is declared when there is evidence of transmission of the disease within the hospital on a single unit. Below is how we decide if there is a COVID-19 outbreak at UHN, where we have a low threshold to declaring an outbreak. Declaring an outbreak lets us put in additional measures to work towards preventing further transmission.
Definition of a COVID-19 outbreak involving patients and staffWhen we have one hospital-acquired patient case, we investigate and initiate outbreak measures to mitigate risk while discussing the situation with Toronto Public Health. Sometimes we call an outbreak on just the one case, depending on the situation. Other times we continue with heightened precautions. If a second case in a patient or staff member occurs within 14 days, an outbreak may be called.
Definition of a COVID-19 outbreak involving staff onlyIf two or more cases occur within 14 days and there is reasonable concern for acquisition of infection within the hospital in these cases – an outbreak is called.
For non-COVID, communicable disease outbreaks, UHN defines an outbreak as an occurrence of cases of an infectious disease in excess of what would normally be expected on a clinical unit or units, where patient safety is deemed to be at risk. Read UHN's
outbreak policy to learn more about how we handle communicable disease outbreaks at our hospitals.
Who declares an outbreak?
It is a joint decision made by UHN – with our Infection Prevention and Control (IPAC) and Occupational Health teams – and Toronto Public Health.
What steps is UHN taking to address the outbreaks?

If you are a patient with questions or concerns about coming to the hospital, please contact Patient Relations at 416 340 4907 or
UHN continues to manage our activities to balance the needs of our patients with public health measures.
Patients who have symptoms will still be permitted to access the hospital. Please answer the screening questions honestly. If you do not "pass" the screening, you will still be allowed to enter while taking extra precautions to keep you, other patients, and our staff safe. Essential Care Partners or visitors who have symptoms will
not be allowed to enter. Essential Care Partners who are fully vaccinated for COVID-19 must still pass our entrance screening.
Everyone must also clean their hands using the hand sanitizer provided and put on a medical mask.
Last Updated: July 4, 2022
Everyone entering UHN must wear a medical mask. Medical masks are available at the hospital entrances.
If you arrive wearing an N95 respirator or KN95-style mask, you may continue to wear it under your hospital medical mask. UHN's medical masks have undergone quality assessments to ensure they are appropriate for hospital use.
Patients must wear a mask at all times while inside the hospital, including inpatients when leaving their room or when others are within 2 metres of them inside their room.
All staff, Essential Care Partners, visitors, vendors, suppliers and contractors must wear their medical mask at all times, except in areas designated for eating and drinking.
Medical exemptions will only be considered for patients, not for Essential Care Partners or other visitors.
Exemptions must be pre-approved by your UHN doctor. If this is your first time coming to UHN, contact the clinic or care area you will be visiting
before coming to the hospital to ask for a medical exemption.
When you arrive:
If you are a patient who has a legitimate medical condition that prevents you from wearing a mask, contact your UHN doctor or nurse practitioner's office
before your first appointment. If your exemption is approved, you will receive a Face Mask Exemption Form. Bring your approved exemption form with your to the hospital, as you will be asked to show it by hospital staff. You will be given a face shield to wear instead.

General Visitor FAQ
What can I expect when coming to the hospital with an Essential Care Partner?
All ECPs must check in at the unit and provide their contact information, in case we need to do contact tracing. Depending on the area of the hospital, your ECP may be asked to come at a scheduled time, wear an ID badge, or receive training for properly putting on and removing personal protective equipment (PPE). There may be other requirements to follow.
Your ECP must stay with you at all times. ECPs are not allowed to travel around the hospital. In some cases, ECPs may be asked to wait in hallways or other areas to allow for physical distancing in the waiting room.

Visitor Vaccine FAQs
UHN's mandatory vaccination policy came into effect on October 22, 2021.

Looking for vaccination resources? Please visit our
COVID-19 Vaccine site.
Why has UHN implemented COVID-19 vaccination requirements for visitors?
As a hospital, it is our responsibility to do everything we can to protect our patients, staff and community. We know that vaccinations are key in helping stop the spread of COVID-19. For that reason, UHN requires that everyone coming to our sites is fully vaccinated. Note – this policy does not apply to patients.
What is the definition of "fully vaccinated?"
To be considered fully vaccinated, you must have received the full series of a COVID-19 vaccine or combination of COVID-19 vaccines, that are
authorized by Health Canada. This means you must have two doses of a two-dose vaccine series, or one dose of a single-dose vaccine series. Your final dose must have been at least 14 days ago.
Learn more about Ontario's vaccination program on the Ontario COVID-19 Vaccines page
If I'm fully vaccinated, do I still need to follow other public health protocols while at UHN?
Yes – all our existing policies and protocols still apply. All visitors must pass self-screening, and continue to wear a medical mask and practice physical distancing and hand hygiene while inside UHN spaces.
Are there exceptions for ECPs who are not fully vaccinated?
Some exceptions will be made in emergency situations, or on compassionate or human rights grounds. Speak with the patient's care team about exceptions. Pre-approval for an unvaccinated ECP will be needed by the
clinic manager, except in an emergency situation.
If an exception is approved, a negative COVID-19 test result will be needed. This can be a rapid antigen test result done on the day of the visit, or a PCR test done within the last 48 hours. A photo can be shown to the manager.

Consider exceptions to the ECP Vaccination Policy for patients who:
I'm assisting someone to the Emergency Department, but I'm not fully vaccinated. What can I do?
If you pass symptom and risk factor self-screening, you can help the patient to the triage area. You will not be allowed to enter the Emergency Department or wait with them, unless approved for an exception.
If approved, you must do a rapid antigen self-test and receive a negative result to enter.
Can I visit a Toronto Rehab patient outdoors, if I'm not fully vaccinated?
Although full vaccination is not required for outdoor visits, we strongly recommend choosing visitors who are vaccinated. If visitors need to go inside the hospital at any time during the visit, such as to pick up a patient or use the washroom, they will need to be vaccinated if over 12 years old.
Whether you are going indoors or not, you will need to pass hospital COVID-19 screening and wear a medical mask.
Who can I speak to if I disagree with a decision for my situation?
For the safety of other patients, visitors and our staff, our clinic and unit managers must follow UHN policies on who can be allowed to enter UHN during the pandemic. They are only able to permit Essential Care Partners for patients or situations that fit within the current safety criteria.
If you are declined approval by the unit/clinic manager, but feel that you should be eligible, you can contact UHN Patient Relations at 416 340 4907 or

I worry that I might have COVID-19. Can I come to the Emergency Department to be tested?
If you are having difficulty breathing or experiencing other severe symptoms, call 911 immediately. Advise them of your symptoms and any travel history.
If you have mild symptoms, do not come to the Emergency Department. Self-isolate and call your primary care provider, Telehealth Ontario, or use an online assessment tool to see if you need to be tested or how to access further care, if needed.
Can I pick up my prescriptions?
Yes, our outpatient pharmacies are open.

Will there be changes to the UHN shuttle bus?

During a virtual visit, you do not come to the hospital to meet in person. Instead, you speak with your care team using a regular phone, smartphone, tablet or computer.
Virtual visits are not new. UHN and healthcare teams across Ontario have been using virtual visits for some time. We are using virtual visits more often at UHN to reduce how many people come to the hospital. This is to protect our patients, staff and the community from the spread of COVID-19.
Your healthcare team talks to you about your current health status, any symptoms you are experiencing and your needs. If your care team feels that an in-person visit is needed instead of a virtual visit, they will discuss your options and next steps with you.
