York Region’s ONLY 24/7  Veterinary Emergency and Referral Hospital


24/7/365 – no appointment required

At the 404, we know that emergencies don’t always happen on weekends or after supper on a weeknight.  While your primary care veterinarian is always your first point of contact when such an emergency arises, we are here, available to see you and your pet 24 hours a day, 7 days a week, and 365 days a year, when you need us.  As the only 24/7 veterinary emergency & referral facility in York Region, our emergency service takes no holidays!

Supported by our own team of veterinary specialists

One of our emergency service’s most valuable assets is its association with our referral/specialty department.  It is all one hospital, no fragmented ownership – all of us under one common banner with one common mission – to help the people and pets of York Region.  Our emergency vets have ready access to the expertise of board-certified specialists in surgery, internal medicine, anesthesiology and dermatology, and all the great diagnostic equipment that comes with them- ultrasound, digital radiography (x-rays), endoscopy (important in foreign body retrievals), and computed tomography (CT), just to name a few.  Our digital radiography and CT images can be sent for interpretation by board-certified veterinary radiologists 24/7/365 with STAT interpretation available within 30min.

Board-certified surgeons on-call 24/7 for ALL surgical emergencies

In the human healthcare model, emergency surgeries are not performed by emergency doctors. The surgery specialist on-call is called in, thus enabling the emergency doctor to continue seeing new incoming emergency patients, and guaranteeing the patient on the operating table is receiving surgery by the most skilled hands. At the 404, this is the model of care we believe in. If your pet requires emergency surgery, it will be performed by one of our board-certified small animal surgeons whether it is 3am or 3pm – specialist surgical expertise for patients who often need it the most. No more stressful transfers from one hospital to another just to get the problem fixed. Orthopedics, thoracic and abdominal surgeries, complex wound repair, neurosurgery …. we can do it all right here, 24/7.

We are one of very few veterinary hospitals in North America, the only veterinary hospital in Canada in fact, to offer rapid, detailed imaging via a 64-slice CT (computed tomography) unit.   Our CT is available for use by both our emergency service around the clock, as well as our various specialty departments.   To learn more about CT imaging for your pet, click here.
