Canada lost its measles elimination status in November 2025. To regain it, the strain must stay out for at least 12 months, according to the Pan American Health Organization.

“Measles continues to circulate globally, and we can expect to see further travel-related cases here at home,” said Dr. Joss Reimer, the chief public health officer.
