Halton Region Public Health confirmed a measles case in Milton on September 2, 2026, marking the first confirmed case in the region this year. The infected person visited several public places in Milton in late August, and health officials are warning anyone who was at those locations during those times to watch for symptoms.
Measles is a highly contagious disease that spreads easily through the air. Public health is reaching out to known contacts who may have been exposed at the following locations: Real Canadian Superstore at 820 Main St E on August 23 from 9 p.m. to midnight; HomeSense at 55 Ontario St S on August 23 from 4:30 p.m. to 11 p.m.; and Santa Maria Medical Centre at 604 Santa Maria Blvd #1 on August 25 from 1 p.m. to 8 p.m., August 28 from 12:40 p.m. to 8 p.m., and August 29 from 12:10 p.m. to 5 p.m.
Halton Region Public Health says residents who visited these locations during those times should monitor for symptoms of measles, which include high fever, cough, runny nose, red watery eyes, and a red blotchy rash that starts on the face and spreads to the rest of the body. Anyone who develops symptoms should call their healthcare provider before visiting a clinic or hospital to avoid spreading the virus to others.
Dr. Patrick Galange, Associate Medical Officer of Health for Halton Region, said measles is a serious disease that can be prevented with a safe and effective vaccine. He encouraged everyone to make sure their immunizations, including measles, are up to date, especially children who may have missed routine shots during the COVID-19 pandemic.
Ontario reported 30 measles cases as of August 18, 2026, but Halton was not among the nine public health units with cases at that time, so this is a new report. The province saw its largest measles outbreak in decades from October 2024 to October 2025, with 2,377 cases. Most of those cases were in unvaccinated people, and one death was reported. Canada lost its measles elimination status in November 2025 because the virus kept spreading for more than a year.
