Advisories and Updates


On March 27, 2022, the first case of highly pathogenic avian influenza (HPAI) was confirmed in a poultry flock in Ontario. The Canadian Food Inspection Agency (CFIA) is leading the investigation. Subsequent cases to date are in the chart below.

The Ministry of Agriculture, Food and Rural Affairs (OMAFRA) will continue to work with the Canadian Food Inspection Agency (CFIA), who is leading the disease response, the Feather Board Command Centre and the commercial and small flock poultry sectors to support producers and poultry owners to reduce further spread of the disease.

Biosecurity remains the best tool for producers to protect their flocks from avian influenza. OMAFRA has extensive plans in place and will continue to work with industry and government partners to provide information to producers to help address their financial, family support and animal care needs.

Poultry producers and owners who have concerns about the health status of their flocks should contact their veterinarian.

Avian influenza is not a threat to food safety but impacts birds. Ontario poultry and eggs are safe to eat when proper handling and cooking takes place.

Avian influenza can cause production and economic losses. Poultry producers and owners who have concerns about the health status of their flocks should contact their veterinarian.

Ontario cases, to date can be found on CFIA's website.

Biosecurity for Ontario Poultry Farms and Flocks

Biosecurity remains the best tool for producers to protect their flocks from avian influenza.

Poultry producers and small flock owners are encouraged to maintain strict biosecurity to prevent future outbreaks and are encouraged to contact their veterinarian if they have concerns about the health status of their flocks. A list of available veterinarian clinics that treat small flock poultry species in Ontario is here.

Clinical signs of avian influenza in poultry flocks can vary widely, and may include:

  • A drop in water and feed consumption
  • Decreased egg production
  • Soft-shelled eggs
  • Coughing and sneezing
  • Diarrhea
  • Bruising of the limbs
  • Listlessness
  • Sudden increase in mortality rate.

The incubation period ranges from 2 to 14 days.

Avian influenza is not a significant public health concern for healthy people that are not in routine contact with infected birds. It is uncommon for avian influenza to impact human health, however those who directly work with poultry should take additional precautions, follow all public health guidelines and maintain strict biosecurity.
