Ontario SPCA and Humane Society’s Spay/Neuter Services

Thank you for your interest in the Ontario SPCA’s Spay/Neuter Services.


On the first Monday of every month, we will open bookings for that month at both Ontario SPCA and Humane Society spay/neuter locations. As of April 3, spots will be available for both cats AND dogs.

To make the booking process more streamlined, there will no longer be a waitlist for spay/neuter services. Be sure to visit this page on the first Monday of every month where a link to our registration page will be posted. The registration forms open at 10 a.m. Spaces will be filled on a first-come first-served basis.

Due to overwhelming demand, booking availability fills up within MINUTES of registration opening each month. If you do not receive an email within 30 minutes of submitting your form (check your junk or spam folders) then your registration was not accepted, and you will need to try again next month.

We are grateful that you recognize the importance of spaying or neutering your animal. We also appreciate your patience, as the demand for spay/neuter services is greater than the number of surgery appointments we have available. As a registered charity, the Ontario SPCA can only accommodate so many animals each month at our spay/neuter locations. We are committed to continuing to expand our services when we have the capacity to do so.

June registration is now closed. We will continue to open our waiting list on the first Monday of every month at approximately 10 a.m. with a limited number of surgical appointments. Thank you for your patience and understanding.

Additional Services 


It is recommended that you have your pet vaccinated at least two weeks prior to your spay/neuter appointment. Animals that have been vaccinated previously should be accompanied by proof of vaccination. Should you be unable to have this done in advance, vaccines can also be given at the time of surgery. We recommend that your pet have the following vaccines: Rabies vaccine (3 year), Feline Leukemia vaccine, FVRCP vaccine and DA2PP vaccine.

*Note: It is a legal requirement and strongly recommended that ALL animals be vaccinated for rabies regardless of whether or not they go outside. If your animal is currently vaccinated for rabies, proof of vaccination should accompany your pet at the time of surgery.


$27 provides your pet with a unique, permanent form of identification. All shelters and many vet offices have the ability to read microchips, and your animal would be returned to you safely and quickly should it become lost. This fee includes an offer of 30 days of free pet health insurance. *Insurance offer does not apply to animals owned by rescue/shelter organizations.

E-Collars and Surgical Onesies

We STRONGLY recommend that all animals be deterred from licking their surgical sites through the use of Elizabethan collars (e-collars) or surgical onesies. If your animal does lick, they can open their incision or cause infection, incurring additional veterinary costs.

E-collars can be purchased the morning of surgery for $16. (Note: If you choose to purchase your e-collar from a pet store, please ensure that when pushed back against your pet’s shoulders, the collar extends at least 1″ past his/her nose).

Surgical Onesies can be purchased on the morning of surgery for $31.


A deposit is due at the time of booking in order to obtain an appointment. Credit card payments can be made over the phone, and debit/Visa-debit/cash payments can be made in person, at our offices. Money orders can also be mailed, made payable to the Ontario SPCA (please include your phone number on the money order).

Thanks to a grant provided by the Pet Valu family of stores, the Ontario SPCA launched its SPCA Mobile Animal Wellness Services Unit in 2019 year to deliver wellness examinations and spay/neuter services to underserved communities. In addition to supporting hundreds of local animal shelters and charities through Companions for Change events since 2018, Pet Valu has funded five rescue transportation and mobile health clinics for animal rescue organizations in Nova Scotia, Ontario and British Columbia.
