Through its province-wide network of 50 plus Communities, the Ontario SPCA (Ontario Society for the Prevention of Cruelty to Animals) is one of the largest, most responsive animal welfare organizations in the country, providing care and shelter for tens of thousands of animals every year.

As a non-profit charitable organization, the Ontario SPCA is unique amongst animal welfare organizations in Ontario: the Ontario SPCA Act mandates the Society to enforce animal cruelty laws and provides Ontario SPCA Community investigators with police powers to do so.

For over a century the Ontario SPCA has provided province-wide leadership on matters relating to the prevention of cruelty to animals and the promotion of animal welfare, and worked with its Communities to encourage humane and suitable animal care; call attention to unacceptable practices that harm animals; investigate cruelty complaints; carry out rescues; bring perpetrators of cruelty to court; advocate for humane laws; and provide care to all animals in need.
