The Department of Anesthesia and Pain Medicine provides anesthetic care to over 20,000 infants and children per year. Thirty-eight full time paediatric anesthesiologists, 10 paediatric anesthesia fellows, 10 residents, 6 nurse practitioners/clinical nurse specialists and 2 clinical psychologists are dedicated to delivering clinical care to patients at SickKids.   

Exceptional patient care

Providing exceptional patient care to a clinical caseload that is high in both volume and complexity is at the core of what we do. We deliver all aspects of perioperative care for infants and children undergoing a full range of quaternary surgical procedures at SickKids, including cardiac surgery, craniofacial surgery, neurosurgery, neonatal surgery, solid organ transplantation, and interventional radiology. SickKids also maintains a busy ambulatory same-day surgical unit, and is a designated paediatric trauma center for the Province of Ontario.   
Our Pre-Anesthesia Clinic provides comprehensive pre-anesthesia patient evaluation, information and patient education. We offer an Acute Pain Service and a Chronic Pain Clinic that is a specialized multidisciplinary service for the assessment and treatment of children and adolescents with chronic pain. Our Chronic Pain Clinic is comprised of an experienced team of anesthesiologists, advanced practice nurses, a psychologist, a psychiatrist, and a physiotherapist. Within the Department, members of the Division of Cardiac Anesthesia provide an important area of highly specialized clinical care, offering specific expertise in the care of children undergoing surgery for congenital heart disease. 

Always innovating

We are constantly striving to improve the delivery of anesthetic care. To this end, our team of researchers is passionate about research and innovation.  We have thriving research programs in basic science, clinical research, patient safety, medical simulation, and education. In addition, we are passionate about educating future generations of paediatric anesthesiologists, and we offer comprehensive training in all aspects of paediatric anesthesiology and pain medicine, including a general fellowship in paediatric anesthesia, and advanced fellowships in paediatric cardiac anesthesia, paediatric pain medicine, and research.

Programs and services

The Department of Anesthesia and Pain Medicine includes areas of Anesthesia Research, Chronic Pain Research and Treatment, Acute Postoperative Pain Management and Preoperative Assessment. 

Expand the sections below to learn more about each program and service associated with Anesthesia and Pain Medicine.

The Acute Pain Service (APS) is a consultative service that is called by a patient's primary care team to help manage pain while the patient is in hospital. Many patients seen by the Acute Pain Service have postoperative pain. The team is also consulted by paediatricians to assist with patients who suffer from pain related to their medical conditions. Common examples are sickle cell disease, mucositis from chemotherapy, cancer pain and major burn injuries. 

The Transitional Pain Clinic provides pain management care to children, teens and their families whose pain is difficult to manage at home. This includes before or after a painful procedure such as an operation or intervention, as well as before being discharged from hospital. 

The Chronic Pain Clinic at SickKids is a specialized service for the assessment and treatment of children and adolescents with chronic pain. It is made up of an experienced team of anesthesiologists, advanced practice nurses, a psychologist, psychiatrist and physiotherapists. They provide family-centred care and offer treatments and therapies based on the best evidence.

The physicians in the Cardiac Anesthesia division have specific expertise in the care of neonates and children with congenital and acquired heart disease undergoing cardiac surgery and cardiac catheterization.  

They also take care of patients with cardiovascular disease undergoing other procedures requiring sedation or general anesthesia. They are involved in evaluation, pre-operative assessment and consultation, before heart surgery and non-surgical cardiac procedures. They coordinate care especially for patients requiring multiples procedures. The objective of the cardiac division is to develop and refine strategies, equipment, drugs and techniques for ensuring patients' safety and providing the best quality of care before, during and after a procedure.  

Several members of the group are involved in translational and clinical research, including cardiovascular physiology, new technology, regional anesthesia and pain management, perioperative outcome, as well as transfusion and hemostasis.

Our division also includes experts in education and quality and safety. We are one of the major training centers for Canadian and international cardiac anesthesiologists who wish to specialize in the care of children with heart disease.

Certain members of the Department are designated clinical teachers with the Faculty of Medicine, University of Toronto. Staff anesthesiologists engaged in clinical and basic science are cross-appointed to the SickKids Research Institute. All full-time staff are members of the Faculty of Medicine, University of Toronto.

Paediatric Cardiac Anaesthesia Fellowship

The Labatt Family Heart Centre provides health-care services for over 600 children who undergo cardiovascular surgery at SickKids each year. The Division of Cardiac Anaesthesia provides perioperative care for children with congenital heart defects and acquired heart diseases undergoing surgery (cardiac and non-cardiac), interventional cardiology/radiology, and diagnostic imaging under general anaesthesia. 

The fellowship offered in paediatric cardiac anaesthesia is considered an advanced specialty training program, and is intended for anaesthetists with prior specialist training in paediatric anaesthesia. The fellowship program aims to further develop clinical subspecialty knowledge and critical skills necessary for the practice of paediatric cardiac anaesthesia. In addition to medical expertise, the fellowship also aims to develop important non-clinical abilities (e.g., academic, educational, leadership, professional) that physicians require to effectively meet the health-care needs of the people they serve. 

The fellowship is typically 12 months in duration, and consists of a framework of structured clinical exposure and educational seminars. In addition to gaining comprehensive clinical exposure in cardiovascular surgery, interventional cardiology/radiology, and non-cardiac surgery for children with congenital heart defects, fellows will have the opportunity to rotate through the departments of echocardiography and critical care medicine. 

The fellowship is structured with an emphasis on advancing clinical expertise, and consists of four days per week of clinical anaesthesia exposure and one day of non-clinical (academic) time. Non-clinical time can be adapted to meet the career goals and academic interests of individual fellows. 


Applications for fellowships commencing in July 2025 will be accepted from January to April 2024.

If you have also applied to the U.S match through the National Residency Matching Program (NRMP), please be advised that the University of Toronto is a participating institution and adheres to the match policy. The policy states that "Applicants who have matched to a program or have accepted a position during the Supplemental Offer and Acceptance Program (SOAP), shall not apply for, discuss, interview for, or accept a concurrent year position in another program prior to the NRMP granting the requested waiver".  For more information visit the National Residency Matching Program (NRMP) website.
