Canada Faces Unprecedented Measles Outbreak as Cases Surge in 2025

With over 3,800 cases reported in Canada this year, health experts are concerned about low vaccination rates and the spread of misinformation fueling the resurgence of measles.

Currently experiencing the highest measles outbreak in North America, Canada’s case numbers—especially in Alberta and Ontario—are alarming health officials. Vaccine hesitancy, particularly among certain communities, and the spread of misinformation are primary factors contributing to this public health crisis.

Canada is grappling with an alarming resurgence of measles, with over 3,800 cases reported so far in 2025, primarily affecting children and infants. Alberta and Ontario are the provinces hardest hit, raising serious doubts about why the virus is spreading more aggressively in Canada compared to the United States. A mother from Alberta, Morgan Birch, shared her shock when her four-month-old daughter contracted measles after health officials confirmed the diagnosis, highlighting the sudden alarming rise in cases in a country where the illness was declared eliminated in 1998.

Despite Canada's smaller population, it ranks eighth in measles outbreaks among western nations according to the CDC. The outbreak's epicenter lies in Alberta, which has the highest incidence rate in North America. Comparatively, the U.S. cases are significantly fewer, attributed to the emergence of vaccine-hesitant public figures, although Canada lacks a similar figure in its health narrative.

The outbreak in Ontario began in late 2024 during a large Mennonite event, where a community with historically lower vaccination rates became significantly affected. Healthcare providers from mobile clinics have indicated that nearly all patients with measles were unvaccinated. The rapid transmission of the virus among Low German-speaking Mennonites, combined with rising distrust in the healthcare system and misinformation about vaccines, has worsened the situation.

Experts note that while current statistics reflect the alarming spread, the actual number of infections could be much higher, indicating underreported cases. Vaccine rates in the region have plummeted, with some reports showing a near 50% drop in MMR vaccinations since the pre-pandemic years, further exacerbating the risk of outbreaks.

Public health units are attempting to counter the vaccination hesitancy sparked by pandemic-related disruptions and misinformation, but the response has been tepid, lacking the urgency seen during COVID-19 outreach efforts. Health officials are now revising vaccination strategies and encouraging higher uptake among the population. The ripple effect of this outbreak continues to unfold as families, health officials, and communities grapple with the ramifications of vaccine hesitancy and the urgent need for public compliance with vaccination protocols.
