The Public Health Agency of Canada (PHAC)’s Data, Surveillance and Foresight Branch (DSFB) and National Collaborating Centre for Infectious Diseases (NCCID).

Date and time: June 25, 2024 | 1:00 to 2:00 Eastern Time / 12:00 to 1:00 Central Time

Language: English (we encourage questions to be asked in your choice of the official languages).


One Health is an integrated, unifying approach that aims to sustainably balance and optimize the health of people, animals and ecosystems. Canada needs the capability for early detection, understanding and action to address One Health threats and reduce their potential wide-reaching impact.

The Public Health Agency of Canada, in collaboration with other multi-sectoral partners, has developed a One Health Approach to Risk Assessment (OHARA) Framework that aims to link existing risk assessment activities and inform the development of new activities where gaps exist. Within the Framework, guidance and best practices are provided to enhance collaboration.

The success of the approach requires awareness, endorsement and willingness to collaborate by all One Health partners. Senior leadership within all relevant sectors must be in agreement on the importance of increased collaboration across sectors and acknowledge that it may at times require effort from risk assessors and subject matter experts outside of the traditional mandates of their organizations for the sake of the greater good.

By the end of this seminar, participants will be able to:

  • Understand the scope and importance of One Health
  • Recognize challenges to multi-sectoral work and some best practices for overcoming these challenges
  • Foster the ability to think outside organizational mandates for the greater good
