Join the team that changes lives – starting with yours.

Join the Ontario SPCA and Humane Society’s Mobile Animal Surgical Hospital (MASH) team and be part of a compassionate group of veterinary professionals bringing accessible care to underserved and First Nations communities across Ontario. Experiencing a MASH clinic is more than joining a supportive team of veterinarians, RVTs, and veterinary assistants. It is also an exciting opportunity to make a real and lasting difference, help to improve animal health, strengthen the bond between people and their pets, and create positive change.
