Morgan Birch, a mother from Alberta, experienced a frightful realization when her four-month-old daughter, Kimie, developed symptoms that confirmed a measles infection. This unexpected diagnosis comes as Canada faces a significant measles outbreak, with numbers soaring to over 3,800 cases in 2025, predominantly affecting unvaccinated children and infants.
Canada now ranks eighth globally for measles outbreaks, contrary to its previous status after eradicating the disease years ago. The outbreak is centered in provinces like Alberta, which has recorded the highest rate of measles spread in North America. The reasons for the rapid transmission remain a point of scrutiny, especially when compared to the situation in the US.
Experts note a notable absence of influential vaccine-hesitant figures in Canada, unlike the US, which may contribute to the differing proliferation of the virus. However, low vaccination rates in certain communities, particularly among conservative Mennonites resistant to modern medicine, have exacerbated the outbreak.
The outbreak traces back to late 2024, originating from a large gathering in New Brunswick that catalyzed the spread among the Mennonite population in Ontario. As healthcare professionals work hard to combat misinformation about vaccines, many cases stem from deep-rooted hesitancy and distrust in the healthcare system.
In southern Alberta, vaccine administration has plummeted significantly since 2019, which correlates with a surge in both Covid-19 and routine vaccine hesitancy. Some public health officials express concern that the full extent of the outbreak is yet to be realized, as many cases remain hidden within communities.
As measles continues to escalate across Canada, health authorities are urging communities to increase vaccination efforts. With the MMR vaccine proven to be effective in preventing measles, health experts stress the importance of protecting vulnerable populations and combating misinformation with factual health education.
