One Health


What is One Health?

One Health is an integrated effort of multiple disciplines working locally, nationally and globally to attain optimal health for humans, animals and the environment.

The Honours Specialization in One Health, leading to a Bachelor of Medical Sciences (BMSc) degree, was created in collaboration with Western University’s Departments of Sociology and Geography in the Faculty of Social Science to enrich the learning experience of students.

The module offers an innovative, interdisciplinary education and research experience for students, which focuses on the intricate link between animal health, environmental health, socioeconomic factors and human health.

Why is the Honours Specialization in One Health unique?

  • It provides access to unparalleled breadth and depth of knowledge in life sciences, physical sciences, social sciences, and the humanities with the focus on attaining optimal human health.
  • It offers research projects in the senior year with access to supervisors from various departments and faculties at Western University.
