Measles outbreak over after 2 years, thousands infected in Canada: PHAC

Oct 19, 2026 | 2:55 PM

A measles outbreak that spanned two years and infected thousands of people in Canada is over.

The Public Health Agency of Canada made the declaration in a press release Monday, stating that more than 6,400 people were infected across 10 provinces.

Two infants in Ontario and Alberta who were infected with measles while in the womb died after they were born.

The outbreak began in New Brunswick in October 2024 and about a year later led to the loss of Canada’s measles elimination status due to ongoing transmission of the highly contagious disease for more than 12 months.

Canada’s Chief Public Health Officer Dr. Joss Reimer says that although it’s encouraging to see the outbreak declared over, it doesn’t mean that measles is gone.

Infectious disease experts have attributed the return of measles to declining vaccination rates, misinformation-fuelled vaccine hesitancy and distrust of authority, as well as disruptions to routine immunizations during the COVID-19 pandemic.

“Measles continues to circulate globally, and we can expect to see further travel-related cases here at home,” Reimer said in a statement.

Ontario, which was one of the most affected provinces, declared its outbreak over last fall, while Alberta’s ended in July. Public health officials in Manitoba said the province’s last laboratory-confirmed case was in August.
