Spay/Neuter Clinic

logo of the College of Veterinarians of OntarioThe Spay/Neuter Clinic is a City-operated facility which provides dog and cat sterilization and microchipping services. Spaying or neutering pets reduces the number of unwanted domesticated animals and the cost of animal control. The Clinic is a revenue neutral service, meaning that fees are set to recover the cost of services without generating a loss or a profit.  Fees for service are approved by City Council as necessary to maintain that objective.

For more information on the Clinic, please call 613-798-8970 during business hours.

For vaccinations, please contact your local veterinarian.

Advantages of spaying or neutering your pet

Spaying your female pet:

  • Eliminates the heat cycle and associated symptoms such as crying, nervous pacing, the desire to roam and the excretion of blood
  • Stops unwelcome visits by male suitors
  • Reduces the risk of breast cancer, one of the most common malignancies in the female feline
  • Prevents diseases of the uterus and ovaries as well as some skin disorders

Neutering your male pet:

  • Reduces or eliminates the tendency to mark territory with strong-smelling urine
  • Prevents prostate disease and certain cancers
  • May reduce the likelihood that your pet will stray from home and become lost or injured

Common myths about spaying or neutering

Spaying or neutering my pet will cause obesity.— False. Exercise and proper diet will keep your pet healthy and active.

My female pet needs to have a heat period and litter to round out her personality. — False. There is no proven benefit in allowing the animal to have a heat period or a litter prior to spaying.

What happens during the surgery?

A qualified veterinarian must perform both types of surgeries. The procedures are performed under full anaesthesia and sterile conditions.

The spaying of a cat or dog involves the removal of the female reproductive tract. The neutering of a cat or dog involves the removal of the male testes. These surgeries can be performed on cats 4 months or older, and dogs 5 months or older.

Private veterinary clinics also offer spay/neuter services. Check the Yellow Pages for complete listings or consult with your own veterinarian for details on this important aspect of responsible pet ownership.
