The Public Health Agency of Canada has warned that the 2026 FIFA World Cup could increase the risk of infectious disease spread in Canada, with measles identified as the top concern.

In a risk assessment prepared ahead of the tournament, PHAC said measles has a higher likelihood of being imported into Canada and could result in broader transmission during the event. The assessment also identified clade Ib mpox as a moderate risk.

Canada will host World Cup matches in Toronto and Vancouver, bringing large numbers of international visitors into stadiums, airports, hotels, transit systems and public spaces. PHAC said the assessment was designed to support public health planning and surveillance alongside local and provincial preparations.

Measles is a major concern because it spreads easily through the air. PHAC says anyone who has not previously had measles or has not been vaccinated with a measles-containing vaccine is at risk. It also notes that vaccination rates in some areas of Canada are below the threshold needed for community immunity.

The warning does not mean a major outbreak is certain, but it highlights the need for early preparation. Large sporting events can bring together visitors from many countries in crowded settings, creating opportunities for infection to spread if imported cases reach under-vaccinated communities.

Canada already monitors measles nationally, as every confirmed case is reported to PHAC. The federal government says outbreak risk is highest when imported cases enter populations with lower vaccination coverage.

The concern is heightened by Canada’s recent measles history. In November 2025, Canada lost its measles elimination status after nearly three decades because of a year-long outbreak, with transmission mainly occurring in under-vaccinated communities.

For families and travellers, the practical advice is clear: check measles vaccination records before travel or large events, especially for children, teenagers and adults who may not have received two doses. Symptoms to watch for include fever, cough, runny nose, red eyes and a rash.
