Pioneering veterinarians form OVMA

Veterinary work in Ontario has its roots in the agricultural community, tending to settlers’ livestock. By the 1860's, the advent of steamship and railway travel created a need for improved animal care as livestock became more vulnerable to European diseases. The foundation of the Ontario Veterinary Medical Association in 1874 launched organized veterinary medicine in Canada.

Ontario Veterinary Association incorporated

The veterinary profession begins the journey to attain true professional status and the privilege of self-governance.

The Veterinary Science Practice Act is proclaimed

The Veterinary Science Practice Act broadened the scope of veterinary medicine to include domestic animals as well as livestock. The Ontario Veterinary Association, now the College of Veterinarians of Ontario, became a corporate body empowered to govern its members and issue licences.

The Veterinarians Act is updated

The Veterinarians Act provides the College with the authority to develop by-laws to define the administration of the College.
