After nearly 30 years, Canada has lost its measles elimination status according to the country’s public health agency.

In a statement Monday, the agency says the country is currently experiencing a “large, multi-jurisdictional outbreak of measles” that began in October 2024 with cases in Alberta, B.C., Manitoba, New Brunswick, Nova Scotia, Ontario, P.E.I and Quebec.

The outbreak has slowed recently, but has persisted for 12 months, mostly in communities that are under-vaccinated.

Canada can get its status back if the measles strain, associated with the current outbreak is interrupted for at least 12 months.

Meanwhile, the Canadian Medical Association (CMA) says they are disappointed and deeply concerned.

In a statement, the CMA says although the measles is a highly infectious disease, it was eliminated in Canada in 1988 thanks to hard work, health care providers and commitment to get vaccinated.

“For more than 25 years we collectively held measles at bay. We can do it again,” says CMA. “We strongly encourage Canadians to roll up their sleeves to protect themselves, their loved ones and their communities.”

“By working together, we can keep all Canadians safe.”
