Canada declares multi-jurisdictional measles outbreak over

The Public Health Agency of Canada says the multi-jurisdictional measles outbreak that began in October 2024 is over, after more than two months passed without a linked case.

The outbreak involved more than 6,400 cases across 10 provinces and territories. The federal agency said most cases were among people who were not vaccinated.

Ending the outbreak does not automatically restore Canada’s measles-elimination status, which was lost in late 2025. The agency said elimination requires at least 12 consecutive months without sustained transmission from the same strain.

Travel-related cases can still occur. The federal update says two doses of measles-containing vaccine provide strong protection and advises people to check their vaccination status with a health-care provider or local public-health authority, particularly before travel.

The national announcement is broader than recent provincial updates, including Manitoba’s declaration that its outbreak had ended. Québec and Montréal residents should continue to follow local public-health notices for any new exposure locations or vaccination-clinic information.
