April and May appointments are filled.

On the second Monday of every month we will open the majority of surgery bookings for the following month (if the Monday is a holiday, it would be opened the following business day). Wellness clinics are opened as they become available and are usually held once a month, though sometimes more.

Surgery appointments can fill up within MINUTES of opening. Please understand that we are a single charitable organization doing the best we can to provide access to spay neuter.

May 5th and May 7th Wellness Clinics are fully booked. Special Wellness Clinics on May 21, 22 and 30th will be available to book online on Tuesday May 7th at 10am

Check our website daily for any cancellations or if new spots are added as our surgical capacity allows.

Wellness Appointments

CA$25 (for exam only)

Wellness clinics are for healthy pets who have no medical or health concerns. Book your dog or cat in for vaccines, flea and heartworm prevention. We do not diagnose or provide any sort of diagnostic services. Pets who are sick or needing special treatments need to be seen by a full service veterinarian and should NOT be booked in these appointments.
