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.

Dr. Rosemary Cullander is a 2014 graduate of the University of Glasgow Veterinary School where she developed a keen interest in the management and care of emergency and critical patients. Following graduation, she completed a one-year small animal medicine and surgery internship at the Veterinary Emergency Clinic and Referral Center in Toronto. She has been a full time admitting and attending veterinarian with our team at the Veterinary Emergency Hospital of West Toronto since 2015. In her spare time, Dr. Cullander often cares for sick and injured neonatal kittens. Outside of veterinary medicine, she enjoys travel, cooking, gardening and mountain biking.
