Toronto measles exposure advisory follows a travel-related case linked to three Scarborough healthcare locations visited between June 28 and June 30.
TORONTO — Toronto Public Health (TPH) is advising residents to check whether they may have been exposed to measles after confirming a travel-related case involving visits to several healthcare facilities in Scarborough.
Public health officials are asking anyone who was at the identified locations during specific dates and times to review their vaccination status, monitor for symptoms through July 21, 2026, and seek medical advice if symptoms develop.
Parents and guardians of infants under one year of age who may have been exposed are urged to contact Toronto Public Health or 311 immediately, as eligible infants may qualify for immunoglobulin treatment to help prevent infection.
Potential Exposure Locations
According to Toronto Public Health, members of the public may have been exposed at the following locations:
Sunday, June 28
- Scarborough Health Network – General Hospital Emergency Department waiting room
- 3050 Lawrence Ave. E.

Monday, June 29

Highly Contagious Virus
Toronto Public Health says measles spreads easily through the air when an infected person breathes, coughs, sneezes or talks.
The virus can remain suspended in the air or survive on surfaces for up to two hours, meaning people can become infected even after an infected individual has left the area.
Check Vaccination Status
Health officials emphasize that measles is preventable through vaccination.
Current recommendations include:
- Children typically receive their first measles vaccine at 12 months of age.
- A second dose is administered between four and six years of age.
- Individuals born in 1970 or later should have received two doses of a measles-containing vaccine if they have not previously had measles.
- Anyone unsure of their vaccination status who is at least one year old can safely receive the Measles, Mumps and Rubella (MMR) vaccine, or consult a healthcare provider about blood testing to confirm immunity.
Monitor for Symptoms
Residents who may have been exposed should monitor themselves for symptoms until July 21.
Symptoms may include:
- Fever
- Runny nose
- Cough
- Red eyes
- A red rash that begins on the face before spreading down the body
- Small blue-white spots inside the mouth, known as Koplik spots
TPH advises people to remain vigilant for symptoms even if they have previously been vaccinated.
Call Ahead Before Seeking Medical Care
Anyone who develops symptoms should contact a healthcare provider immediately.
Toronto Public Health recommends calling ahead before visiting a doctor’s office, clinic or hospital so staff can take precautions to reduce the risk of transmission.
Individuals seeking medical assessment are also advised to wear a well-fitting medical-grade mask, such as an N95 respirator.
Five Travel-Related Cases Reported This Year
Toronto Public Health has now confirmed five travel-related measles cases in 2026.
Officials also remind residents planning international travel that measles activity has increased in several parts of the world. Families travelling abroad should ensure vaccinations are up to date before departure. Infants between six and 12 months of age may be eligible for an early MMR vaccine dose when travelling to higher-risk destinations.
