Canada Concludes Two-Year Multi-Jurisdictional Measles Outbreak

The Public Health Agency of Canada, with provincial and territorial officials, declared the end of a multi-jurisdictional measles outbreak that began in October 2024. The outbreak led to over 6,400 cases across 10 provinces and territories, causing Canada to lose its measles elimination status in late 2025. Most affected individuals were unvaccinated, and PHAC warns of continued vigilance due to global spread.
