Canada's ongoing avian influenza outbreak has now affected an estimated 16.59 million birds nationwide, according to the latest update from the Canadian Food Inspection Agency (CFIA) as of November 26, 2025. The figure includes birds that died from infection and those humanely depopulated to prevent further spread.
Since detections began accelerating in 2022, the virus has continued resurfacing across multiple provinces, prompting strengthened biosecurity measures and renewed warnings to commercial and backyard bird owners.
