Trap Neuter Return

Welcome to Toronto Humane Society’s TNR Services

As a member of the Toronto Feral Cat Coalition, Toronto Humane Society is committed to offering support for the city and surrounding cities’ feral cat populations and their colony caretakers. As we are not a city run program, all services are supported by our Public Veterinary Services.

All TNR services require colony caretakers to have their colonies registered with their city or town, and most importantly to have taken the “Trap-Neuter-Return: How to Manage a Feral Cat Colony” offered through the Community Cats Toronto. Please visit their website for upcoming course dates and registration.

*Toronto Humane Society is continuing to conduct Trap Neuter Return appointments during our regular 9:00 AM - 5:00 pm operational hours. Due to COVID-19 and new safety protocols that are in place you may experience delays. We apologize for this inconvenience and thank you for your time and understanding.

Clinic Hours of Operation:
*Daily Drop-off: 9:00am – 5:00pm
Pick up times will be provided upon drop off by one of our clinic team members.


Please refer to our Calendar of Events Page.


*Drop-off must be completed by the registered colony caretaker in order to fill out surgical authorization forms. Pick-up can be arranged with another registered colony caretaker. (No family members or friends of the colony caretaker are permitted unless they are also certified).
