Toronto Public Health is warning parents, especially those with children under a year old, of possible measles exposures last week in Scarborough. A travel-related case may have caused people to be exposed to the virus at health-care facilities between June 28 and 30.
Possible exposure sites include Scarborough Health Network’s General Hospital emergency waiting room at 3050 Lawrence Ave. E. on June 28 between 7 a.m. and 1:30 p.m., Markington Family Care and Walk-in Clinic at 3227 Eglinton Ave. E. on June 29 from 9 a.m. to 3 p.m., and Scarborough Health Network’s General Hospital Kids Outpatient Clinic at 3050 Eglinton Ave. E. on June 30 from 8 a.m. to 3 p.m.
Parents or guardians of infants under one year of age who may have been exposed to measles should contact Toronto Public Health or 311 immediately as they may be eligible for immunoglobulin treatment to help prevent infection.
Measles is highly contagious and is spread through the air when an infected person breathes, coughs or sneezes. The virus can survive in the air or on surfaces for up to two hours.
Measles has seen a resurgence in the last few years, with Canada losing its measles-elimination status from the Pan American Health Organization in November 2025. This year, Toronto Public Health has reported five measles cases linked to travel outside of Canada.
People who may have been exposed to the virus are advised to check their vaccination records for measles protection. If they did not receive two doses of the vaccine or have not had the virus, they are at risk of infection.
Anyone unsure about their vaccination status who is one year of age and older can safely receive the measles, mumps and rubella (MMR) vaccine. A blood test can also be done to determine immunity.
People who may have been exposed should monitor for symptoms until July 21, which could include fever, runny nose, cough, red eyes and a red rash that begins on the face and spreads down the body. Blue-white spots can also appear on the inside of the mouth and throat.
If symptoms develop, contact a health-care provider immediately, including before visiting a health-care facility so they can mitigate the spread of the virus.
