Canada's Measles Elimination Status Cancelled

The Pan American Health Organization (PAHO) today announced Canada has lost its measles elimination status, which was attained in 1998.

According to the PAHO press release on November 10, 2025, Canada can re-establish its measles status once transmission of the measles virus has been interrupted for at least 12 months.

During 2025, over 80% of Canada's 5,162 measles cases were reported in Ontario and Alberta.

Currently, the U.S. CDC advises all people traveling to Canada to ensure they are fully vaccinated against measles.
