Measles Exposure Warning Issued for Travellers at Toronto Pearson Airport

Health officials in the Greater Toronto Area have warned travellers of possible measles exposure at Toronto Pearson International Airport and other locations following confirmation of a case involving an unimmunised child.

The Durham Region Health Department issued the warning on Saturday, November 7, 2026, after identifying additional locations where people may have come into contact with the infected child, who had recently travelled internationally.

Three Exposure Locations Identified

One of the exposure locations was Ethiopian Airlines Flight ET552, which travelled from Addis Ababa to Toronto on November 2 and 3.

The flight departed Addis Ababa at 11:32 p.m. East Africa time on November 2 and arrived in Toronto at 7:30 a.m. Eastern Standard Time on November 3.

Other identified exposure locations include Terminal 1 of Toronto Pearson International Airport between 7:30 a.m. and 11 a.m. on November 3, and the emergency department waiting room at Lakeridge Health Ajax-Pickering between 10:40 a.m. and 5 p.m. on the same day.

Anyone who was at these locations during the specified periods has been advised to monitor for symptoms until November 24.

Symptoms and Health Advice

Measles symptoms may include a high fever above 38.3°C, cough, runny nose, red and watery eyes, sensitivity to light and a rash that typically lasts between four and seven days.

Symptoms generally develop between seven and 21 days after exposure to the virus.

Health officials have advised potentially exposed individuals to confirm that they and their family members have received two doses of the measles, mumps and rubella (MMR) vaccine.

Anyone who develops symptoms has been urged to stay away from work and school and call ahead before visiting a healthcare facility or primary care provider to avoid exposing others.

Public Health Officials Issue Wider Warning

The Durham Region Health Department said known contacts in the region had already been notified. However, the wider public warning was issued after officials determined that additional people may have been exposed.

Travellers seeking further information about possible exposure at the airport have been advised to contact their local public health unit or call Health 811.
