Emergency Veterinarians: 

Dr. Attila Stewart was born and raised in the Toronto area. After graduating veterinary school in 2003 he moved shortly after to Newfoundland, Europe then to the United States where he practiced at larger veterinary emergency and referral hospital for small animals. He quickly realized he liked the high pace of emergency medicine and surgery. As he moved back to Ontario he started working in a variety of emergency clinics all over Ontario. In 2011 he started The Veterinary Emergency Hospital of West Toronto, following his vision to offer urgent care, diagnostics, and emergency surgical procedures in Etobicoke. He built his ER practice slowly focusing on high-quality care for every single patient but with a realistic approach. In 2015 he bought the Burlington Veterinary Emergency and Referral Hospital where the same approach is applied. Outside of the veterinary world, he loves any sport that will give him an adrenaline rush. You may find him mountain biking, rock climbing, kiteboarding in the summer and snowboarding in the winter.  He also thoroughly enjoys scuba diving and would take any given chance to go snorkeling with his kids.

Dr. Camilla Amundsen is originally from Norway and graduated from Szent Istvan University in Budapest, 2003 with honor. Due to her love of travel, she has practiced and gained medical experience from several different countries. From sterilization programs for stray dogs in Turkey and Portugal to internal medicine externship and internship in Norway and USA. She has been in Canada since 2006 and worked at several small animal hospitals across southern Ontario before joining the West Toronto Emergency team in 2012. Over the years she has developed a keen interest in ultrasonography and is currently doing abdominal scans for our patients on an emergency basis. The ultrasound images are sent out to a board-certified radiologist for interpretation 24/7. Outside of veterinary medicine, Dr. Amundsen enjoys horseback riding, rock climbing, and hiking.

He has had a lifelong love for cats and feline medicine with special interests in emergency medicine, oncology, and pathology. In his spare time, he enjoys reef aquarium keeping. He lives with his 5 cats and his cockatiel.

Registered Veterinary Technicians (RVT) and Veterinary Technicians (VT):

Joan RVT started working with us since the hospital opened in 2011. She started working in the veterinary industry 15 years ago while completing her BSc in biochemistry at Trent University. She then went on to complete her technician training at Ridgetown College/University of Guelph. After working for many years as a technician for small animal practices and laboratory animal research she found her biggest interest lay in emergency veterinary medicine and in cytology. While continuing in the veterinary world she completed a graduate degree in diagnostic cytology at The Michener Institute/University of Toronto and worked in the human world at UHN in Toronto. Following her passion for animals, she now uses those skills in our in-house laboratory. Outside of work, Joan spends her time with her two children, her husband, and her dog and cat. She enjoys dragon boating throughout the summer and does a variety of arts and crafts.

Ann RVT graduated from Seneca College in 2009. She spent the first few years working in Regular Practices and then in 2013 began working in the veterinary emergency field. Ann has always had a passion for caring for animals, and through the experience of working in emergency hospitals, she has been able to take that passion to the next level in caring for critical patients. She loves the challenge of the ER and takes every opportunity to further her knowledge so as to be able to give patients the best possible care. In her spare time, Ann loves going for hikes and spending time with her husband, son, Whippet and Bearded Dragon.
