In 2025, Canada has seen over 3,800 measles cases, predominantly affecting children and infants, with Alberta as the outbreak's epicenter. The rise is linked to low vaccination rates and misinformation about vaccine safety, as health officials scramble to contain the spread.

The Measles Epidemic: Canada Faces Unprecedented Outbreak in 2025
A concerning rise in measles cases in Canada has sparked worries about vaccination rates and the spread of misinformation, as Alberta leads the country with alarming infection statistics.
With more than 3,800 reported cases in 2025, Canada is experiencing an alarming resurgence of measles, primarily affecting children and infants. This figure is nearly triple the number of confirmed cases in the United States, even though Canada has a significantly smaller population. Alberta has emerged as the epicenter of the outbreak, characterized by the highest per capita rate of measles transmission in North America, raising urgent questions about the effectiveness of Canadian public health measures.
Morgan Birch, a mother from Alberta, was taken aback when her four-month-old daughter, Kimie, displayed symptoms consistent with measles. Birch, initially believing it was a harmless reaction to vaccinations, turned to her grandmother for advice. The confirmation of Kimie's measles diagnosis underscores a worrisome trend: Canada is now one of the few western nations experiencing significant outbreaks, ranking eighth in the world according to CDC statistics.
The outbreak has been partly attributed to low vaccination rates, particularly in certain communities. Alberta’s vaccination rates have notably dipped, with some reports suggesting a drop of nearly 50% in measles vaccinations from 2019 to 2024. Public health experts point to the rise of vaccine hesitancy fueled by misinformation campaigns that began during the COVID-19 pandemic. For instance, the absence of prominent anti-vaccine figures in Canadian public health may not fully explain the recent surge in cases.
In Ontario, the outbreak began in late 2024 after an individual contracted the virus at a large gathering within the Mennonite community. The spread escalated rapidly due to historically lower vaccination rates among some Mennonites, exacerbated by cultural beliefs that discourage immunization. Catalina Friesen, a healthcare worker serving this population, has noted that distrust towards the healthcare system and the emergence of anti-vaccine narratives have hampered immunization efforts.
Despite the daunting situation, experts argue that vaccination remains the most effective tool against measles. Health units across Canada are attempting to combat vaccine hesitancy through public outreach, though responses lack the urgency witnessed during the pandemic. In light of the outbreak, Alberta has even adjusted its vaccination protocol, allowing infants to receive the measles vaccine earlier than the traditional 12 months, in hopes of reducing transmission.
Hopefully, the lessons learned from this outbreak will prompt a much-needed reassessment of vaccination strategies and public trust in healthcare, especially as communities strive to prevent vulnerable individuals, like infants, from contracting diseases that were once eliminated.
