Peel Health Alerts Travelers to Measles Exposure on Two Pearson Flights

Peel Public Health released a public warning on Tuesday, July 11, 2026, at 11:36 a.m. UTC, indicating that passengers on two separate flights linked to Toronto Pearson International Airport may have been exposed to a confirmed case of measles. The alert, issued by officials from the Peel Region health authority, states that the exposure occurred on both flights, though the specific airlines and flight numbers were not disclosed.

The health agency advises anyone who traveled on either of the two flights to watch for typical measles symptoms, such as fever, cough, runny nose, red eyes and a distinctive rash, and to seek medical advice promptly if any signs appear. Individuals who are uncertain whether they were on the affected flights are encouraged to review boarding passes, travel itineraries or electronic tickets for the date in question. The warning also reminds travelers who are not up to date with measles vaccination to consider receiving the vaccine, as it remains the most effective preventive measure.

Measles is recognized as a highly contagious viral disease that spreads through respiratory droplets and can remain infectious in the air for up to two hours after an infected person leaves a space. Because of its rapid transmission potential, public health authorities routinely issue exposure alerts when a confirmed case is identified in settings such as airports, schools or large gatherings. The Peel Region health officials’ decision to issue a notice reflects standard protocol aimed at limiting further spread and protecting vulnerable populations.

Health officials underscore that the risk to the broader public remains low, noting that the virus requires close, prolonged contact for transmission. Nonetheless, they ask anyone who may have been on the two flights to remain vigilant, keep personal health records accessible, and follow up with a health care provider for guidance on vaccination or treatment if needed. The alert will remain on the Peel Public Health website and will be updated should additional information become available.
