Clarkson provides intensive, continuous care for our patients – including those with conditions requiring hospitalization, intravenous fluids, overnight treatments, surgery, and post-operative patients.

No matter what, through weeknights, weekends, and holidays, a veterinarian and Ontario Registered Veterinary Technician (RVT) will be on site. They take care of pets who need emergency medical care after regular hours, and watch over patients who have to remain in the clinic for longer periods of time.

Emergency Services

At Clarkson Village Animal Hospital, our vets are on site so your pet is never left alone like at clinics where vets are “on call”. This unique feature of our hospital provides you with security and certainty. Our onsite staff will monitor vital signs, and administer fluids, medications, and pain management drugs for any animals staying in the clinic.

There is never a need for pets to be left alone at night.

“Because Clarkson Village Animal Hospital is a 24 hour hospital, there is always a veterinarian and qualified technician on-site. This enables us to provide ’round the clock care’ for our hospitalized patients. We are here for your pet when he or she needs us the most. Being able to see critically ill pets recover, thanks to the combined efforts of our dedicated and caring hospital team is one of the most rewarding aspects of my career”.

Pet Emergency FAQs

It’s important to have an emergency plan so if your cat or dog suddenly needs medical care, you won’t be caught off guard.

Here are four steps you can take before an emergency happens to be better prepared:

  1. Familiarize yourself with your local emergency veterinary clinics or pet hospitals, such as Clarkson Village Animal Hospital. The best case scenario is a clinic – like ours – that is open 24/7, every day, with a veterinarian and Registered Veterinary Technician (RVT) on-site at all times. You must make sure that you are not calling an “emergency hospital” with the vet at home on call.
  2. Consider cost – some emergency hospitals charge an extra emergency fee, but at the Clarkson Village Animal Hospital, we do not charge an extra emergency fee; our fees are identical day and night.
  3. Consider how long it would take you to travel to the emergency vet clinic – physical distance is not as important as the amount of time it takes. Also, in the case of emergency, ask the veterinary hospital the anticipated waiting time. A hospital farther away with a shorter waiting time may be a better option.
  4. Write down the emergency clinic’s number and keep it somewhere handy, like on the fridge, in a drawer, or on your phone, so you won’t have to spend time looking it up if an accident happens. You can also keep our address handy, or look us up on your mobile phone to get directions to the hospital.

If you have any uncertainty at all about whether or not your pet needs emergency veterinary care – come right in!

Better to be safe than sorry. Ideally, call the emergency animal hospital or come in straight away.

However, here are some definite signs that your dog or cat needs medical attention right away:

  • Rapid breathing
  • Weak pulse
  • Rapid pulse
  • Body temperature change
  • Difficulty standing up
  • Pale gums
  • Paralysis or difficulty moving
  • Loss of consciousness
  • Seizure
  • Excessive bleeding
  • Straining for urine or stools

Contact the Clarkson Village emergency veterinary hospital immediately at 905-855-2100. We should be able to walk you through what you’ll need to do in order to safely transport your dog or cat to the hospital.

Severely injured or sick pets can become defensive and even aggressive in some cases. Be careful approaching your pet to avoid getting injured if they lash out.

If there is bleeding, get bandage material or even a sock or T-shirt, and place steady pressure on the site of bleeding until you arrive.

If your pet is seizing, please stay away from their mouth.

If your pet may have had access to a poison or prescription medication, please bring in the container(s).

You will be asked to explain the injury or symptoms your pet is experiencing. The trained staff on the phone should be able to quickly determine whether your pet’s condition needs immediate care or not. They’ll advise you about what you should do next.

If your pet needs emergency care, you will be advised to come to the veterinary hospital as soon as possible.

The basic truth is that if you have a concern, any time at all, simply call and come in for a visit with our veterinarian.  No extra fees, no matter the hour or the day. Put your mind at rest, and get the best for your pet.

You can place a dog or cat on a blanket, and use the blanket as a ‘stretcher’. Two people holding two corners can carry a large dog.

If you can safely get your pet into a carrier to bring him/her to the hospital, do so gently.

If your pet is too aggressive to get close to, you should ask the staff at the emergency hospital for help and advice.

We will quickly assess (triage) your pet to see if their situation is truly urgent. If they need immediate care, we take them into the treatment room. Our on-site vet will attend the patient right away. Our vets are not ‘on call’, they are always at work. No matter the time of day or night, your pet will not have to wait for a vet to arrive at our hospital.

If you are already a client, we’ll confirm the information we have on file for your pet.

During the daytime, our friendly client services staff members will keep you company in the lobby while our veterinarian and Registered Veterinary Technicians do everything they can for your beloved pet. If your pet’s emergency happens during the evening or overnight, the Registered Vet Tech will periodically visit the lobby in case you have any questions.


If you aren’t one of our regular weekday clients, you should absolutely still bring your pet in. We will get all of the necessary information from you about your pet’s medical history when you arrive.


If your pet needs to stay overnight, you can rest assured they will never be left alone. Our hospital is always staffed. We will monitor your pet’s vital signs and administer fluids, medications, and pain management drugs if need be.

There is never a need for pets to be left alone at night.

Costs will vary depending on the treatment your pet’s condition requires. The only emergency costs we can predict are for the initial examination.After the examination, the veterinarian will discuss with you the best route to follow for tests and treatments, as needed.

At Clarkson Village Animal Hospital, we do not add an emergency fee to the examination fee. Day or night, you will receive the same price for an emergency examination.

It is always best to phone ahead so we know you are coming and can be prepared for you; we will also help you with directions if needed. However, you do not need an appointment for emergency care.Call us or bring your pet it at any time of the day or night, 365 days of the year.

No matter what, through weeknights, weekends, and holidays, a veterinarian and Ontario Registered Veterinary Technician will be on-site (never just “on call”).

Different foods, plants, and substances are toxic for different pets (e.g. something toxic for a cat may not be toxic for a dog, and vice versa). Click here for a list of pet toxins from the Pet Poison Helpline to find out what is toxic for your pet.

What common foods are toxic for my pet?

  • Grapes or raisins
  • Garlic, Chinese chive, or anything from the Allium vegetable family
  • Onions (from the Allium family but they deserve their own line here!)
  • Macadamia nuts
  • Xylitol (found in chewing gum, many sugar-free baked goods, and some peanut butters)
  • Bones of any type
  • Raw fish and bones
  • Peaches with the pit or any stone fruit
  • Chocolate
  • Avocados
  • Moldy cheese or nuts
  • Yeast dough
  • Alcohol
  • Coffee
  • Tea
  • Prescription and non-prescription drugs and medications

If you think your pet may have ingested something potentially toxic to them, call our 24/7 emergency number 905-855-2100 right away.

If are bringing your pet to an emergency veterinary hospital because of something they ate, try to bring in a sample to help the vet more quickly determine the right treatment.

Maybe. It depends on your specific pet insurance provider, coverage, and your pet’s specific situation.

Different insurance programs offer different protection plans and levels of coverage. For each plan, there are a range of deductibles and premiums. Emergency coverage is usually an option in these plans. Check your pet’s policy or call your insurance company to see if your pet is covered.

There are even plans available in conjunction with a microchip identification system. This will allow you to protect your pet and provide automatic emergency medical care if your pet is lost and injured, and you cannot be immediately contacted.

Pet insurance is an invaluable safeguard, which will ensure that your pet will always be able to receive the best in healthcare. Currently, we believe that Trupanion offers the best coverage.
