Updated November 10, 2025
Requirements for wearing masks while at UHN change in response to respiratory virus season or other outbreak conditions.
As of November 18, 2025, staff, patients and visitors are required to wear a mask when:
- Staff are providing direct care or closely interacting with patients in inpatient, outpatient, and emergency clinical areas.
- In waiting rooms for clinics, the Emergency Department, and other outpatient clinical areas. (Masking remains optional in family lounges.)
- In physician offices
Masks continue to be required in areas where many patients may be at a higher risk of illness. Signs are posted in those areas, letting you know that masking is required.
Wearing a mask is encouraged, but not required, in public spaces, including lobbies, elevators, food courts, and corridors.
Helping Everyone Stay Well
If you are a patient and feeling unwell or have a known infection, let your care team know as soon as possible by phone or when you arrive for your appointment.
If you are a visitor and feeling unwell or have a known infection, stay home. If visiting your loved one is important, please let the care team know and wear a mask.
Frequently Asked Questions
Why is UHN changing its masking requirements again?
We closely monitor rates of respiratory illnesses and adjust requirements as needed.
The change on November 18, 2025, is in alignment with other Toronto hospitals, although the effective date may be different.
Can I wear my own mask for my appointment or when I'm visiting someone?
UHN-approved medical masks are available at all entrances, outpatient clinics, and inpatient units.
If you arrive at UHN wearing an N95 or KN95 mask, you can continue to wear it. If you are wearing a cloth face covering or a disposable mask, please remove it and put on a new medical mask.
What about mask exemptions?
If you are unable to tolerate wearing a mask, please let your care team know when you arrive for your appointment.
Who do I contact with questions?
Your health care team, clinic staff or unit manager is your first point of contact for questions about masking.
If you still have questions, you may contact Patient Relations.
