Public health officials in York Region have confirmed a fifth measles case connected to an outbreak in Vaughan.
York Region Public Health did not provide any details about the new case on Thursday, only releasing the locations of possible measles exposure.
They are at Kids Club Toronto (3377 Bathurst St.) on Sept. 12 between 1:30 p.m. and 7 p.m. and at Cortellucci Vaughan Hospital Emergency Room (3200 Major Mackenzie Dr. W.) from Sept. 15 at 8:30 p.m. to Sept. 16 at 12:35 a.m.
Public health officials are advising anyone who may have been exposed to watch for symptoms and confirm their measles vaccination.
The measles outbreak in Vaughan was declared on Sept. 4.
Dr. Cheryl Young, the associate medical officer of health in York Region, previously said the first case linked to the outbreak was acquired internationally.
“Beyond this, to protect the privacy of the cases, we cannot comment on how the cases are linked,” Young said in a statement at the time.
Measles is a highly contagious respiratory infection, and the virus spreads through the air, with symptoms starting to show seven to 21 days after exposure. They include high fever, cough, runny nose, red watery eyes, and a red rash that typically starts on the head and neck.
York Region is offering a measles vaccine at a walk-in clinic in the ground-floor multipurpose room of 9060 Jane Street on Sept. 18 from 6 p.m. to 8 p.m.
“Measles vaccine to help prevent infection is time sensitive and only works if you get it as close to when you were exposed as possible,” public health said.
According to Public Health Ontario, there have been 42 cases of measles in the province this year that are not linked to another outbreak in Southwestern Ontario.
In that outbreak, the province has reported 2,338 cases between Oct. 28, 2024, and Sept. 16, 2025.
