We have a veterinarian on call for large animal emergency services 24 hours a day, 365 days a year, for our regular clients. If you have an emergency after office hours, please call 613-925-4200 or 613-258-2777 to reach the on-call veterinarian. You will usually need to leave a message on the pager. Please speak clearly and provide all pertinent information when leaving your message, including your phone number. Do not press any keys prior to hanging up as this will cancel your voice message. If you have not heard back from the vet within 20 minutes - place your call again. The vet may be attending to another emergency, and will return your call as soon as they are able.
