Canada has lost its measles elimination status after more than 25 years, as announced by the Pan American Health Organization (PAHO) on Monday.
This decision follows a sustained outbreak that began in October 2024 and has persisted for over 12 months, primarily affecting under-vaccinated communities.
As of October 25, 2025, Canada has reported 5,138 confirmed meas cases nationwide—more than double the total from the past 25 years combined.
The outbreak has resulted in two deaths, both involving premature infants whose mothers contracted measles during pregnancy, and 375 hospitalizations to date.
The Public Health Agency of Canada (PHAC) confirmed that while transmission has recently slowed, the outbreak has persisted primarily in under-vaccinated communities.
To regain its elimination status, Canada must halt transmission of the outbreak strain for at least 12 consecutive months.
Health officials emphasize that vaccination is the most effective way to protect against measles and are urging Canadians to ensure their immunizations are up to date.
