Quick Summary

The Public Health Agency of Canada (PHAC) has declared an end to a two-year measles outbreak that infected over 6,400 people across all but one province in Canada. The outbreak began in New Brunswick in October 2024 and resulted in the loss of Canada’s measles elimination status due to sustained transmission for more than 12 months. Dr. Joss Reimer, Chief Public Health Officer, emphasized that although the immediate crisis is over, ongoing vigilance is necessary because measles continues to circulate globally and could be reintroduced through travel-related cases.

Story summary

As of October 19, 2026, the Public Health Agency of Canada (PHAC) has declared an end to a two-year measles outbreak that infected more than 6,400 people across ten Canadian provinces. The outbreak began in New Brunswick in October 2024 and led to the loss of Canada’s measles elimination status due to ongoing transmission for over twelve months. Two infants—one each from Ontario and Alberta—died after being infected with measles while still in their mothers' wombs. PHAC attributes the resurgence of measles to declining vaccination rates, misinformation-driven vaccine hesitancy, distrust of authority, and disruptions to routine immunizations during the COVID-19 pandemic. Dr. Joss Reimer, Canada’s Chief Public Health Officer, emphasized that although the outbreak is over, measles continues to circulate globally and could still enter Canada through travel-related cases.
