Department of Bioethics

The Department of Bioethics at SickKids is an academically grounded and clinically and organizationally-focused ethics service. As leaders in paediatric bioethics, we collaborate locally, nationally, and internationally to improve the health and care of children through consultation, education, policy, and research. We provide bioethics analysis grounded in ethics literature, policy, law and stakeholder engagement. Our SickKids Ethical Decision-Making Framework (PDF) guides our practice.

Our vision: healthier children, better care through principled decision-making.
To achieve our vision, the Department of Bioethics will:

  • Engage with and support our colleagues, patients, and families through clinical and organizational consultation
  • Extend the scope and quality of ethics education initiatives for health professionals, trainees, and staff
  • Initiate and enhance policy work through ethical analysis
  • Generate and collaborate on research and scholarship that inform and improve healthcare delivery for children


We engage with SickKids staff, patients, families, trainees, and volunteers to discuss ethical issues they face. Bioethics consultation involves identifying values and viewpoints, exploring fair decision-making processes, and examining the ethics of different options.


We conduct research to systematically explore many ethical issues in health care. We publish our work for academic and public audiences, prepare grants, and collaborate with other institutions on research projects. We participate in international research collaborations on topics of paediatric bioethics, research ethics and artificial intelligence/machine learning.


We provide training and capacity-building for staff and trainees to recognize and analyze ethical issues across the organization. We are affiliated with and teach at the University of Toronto (U of T) .


We are actively involved with or lead hospital policies that have ethics-related content.


Contact us

Patients, families, staff, volunteers, and researchers at SickKids may reach out to our team of bioethicists for any matters relating to the department’s pillars or for consultation about ethical issues. SickKids patients and families may request a consultation by email. The team is available to consult online, by phone and in-person. This information does not need to reach your clinical team if you wish, subject to legal limitations. External consultation may be available upon request.

Our history

In the early 1980s an Ethics Committee was created at SickKids. This was initially a large body of professional and lay members who undertook reviews of ethical issues in clinical care. Dr. Abbyann Lynch, then Director of the Westminster Institute was invited to assist the committee in its deliberations. In 1991, with recognition of the increasing need for bioethics expertise, Dr. Lynch was appointed as Bioethicist and a Bioethics Department was created. The Department functioned in collaboration with the Committee and its Chair. Work groups developed a consultation process, an educational task force and other initiatives to enhance ethics awareness throughout the hospital. A second bioethicist was recruited to the Department within a short period of Dr. Lynch’s tenure.

The Department under Dr. Lynch was extremely active and productive: they published a number of books and research papers, developed a paediatric ethics teaching manual for residents, initiated a newsletter, held numerous ethics education sessions and many other activities to raise awareness.

It became clear that the optimal means for ethics consultation was through the expertise of the Bioethicists, with the committee focusing more on organizational and educational initiatives. Over time these activities also became incorporated into the functioning and responsibility of the Bioethics Department. Bioethics activity at SickKids became the responsibility of the Bioethics Department, led by the Director. This pattern continued under Dr. Christine Harrison and the current Director, Dr. Randi Zlotnik Shaul.

This model has served the institution extremely well and the Bioethics Department is well recognized for its expertise and excellence in clinical consultation, education, research activity, scholarship and policy development. It has established an international name as a major centre of academic bioethics, collaborating locally, nationally and internationally, in the understanding and addressing of complex ethical issues affecting children’s health care.
