What is OAHN?

What is OAHN?


Public trust and confidence from a collaborative animal health network in Ontario.


Coordinated preparedness, early detection, and response to animal disease, through sustainable cross-sector networks.


  • Each species has an expert network
  • For most networks, a quick, species-specific survey is distributed quarterly to veterinarians to identify syndrome prevalence (e.g., increased cases of neurologic signs).
  • Lab data will be compiled quarterly noting top pathogens/diseases affecting each species from AHL and IDEXX lab data (IDEXX data for horse sector only at this time)
  • Species Expert Networks meet quarterly to discuss and interpret lab and survey results, what it means for the industry, and create action items (e.g., OMAFRA veterinarian to create a fact sheet, AHL to make a podcast, OAEP to notify OEF or ORC of an issue)
  • Focus on trends, risks and actionable items for each industry (e.g., continuing education needs, research needs, emergency preparations)
  • Reports generated quarterly for each species for veterinarians and for stakeholder groups
  • The Expert Network will be involved with outbreak risk assessments with OMAFRA or urgent matters where consultation with veterinarians is required.

Expert Networks:

  • 3 private practitioner veterinarian representatives (*species experts may be elected in place of a veterinarian if not available, in industries such as bees). Representatives will be selected by their peers.
  • AHL specialist, OMAFRA specialist, OVC species specialist
