Program Information

Complex Obstetric Surgery is within the field of Obstetrics & Gynecology concerned with the diagnosis, management and treatment of complex obstetric surgery in pregnancy. The Fellowship is based primarily at Mount Sinai Hospital, a high-volume leading tertiary-level obstetric care facility in Toronto. Secondments are to Credit Valley Hospital (Trillium Health Partners) through longitudinal modules in Advanced Gynaecological Surgery.

Upon completion of training, the Fellow is expected to be a competent specialist in Complex Obstetric Surgery, capable of assuming the role of consultant. The Fellow must acquire a working knowledge of the theoretical basis of the specialty, including its foundations in the basic medical sciences and research. The Complex Obstetric Surgery consultant possesses the appropriate medical, surgical and obstetrical knowledge and skills with educational and research interests, administrative ability and special training in the identification and management of complex obstetric surgical problems. Specialists in Complex Obstetric Surgery are consultants to their general Obstetrician colleagues and related health care providers. Their practice is focused on referred high risk obstetric surgery patients, and to provide ambulatory emergency assistance to colleagues when required in their respective centres.

Fellows must demonstrate the requisite knowledge, skills, and attitudes for effective patient-centred care and service to a diverse population. In all aspects of specialist practice, the graduate must be able to address ethical issues and issues of gender, sexual orientation, age, culture, and ethnicity in a professional manner. 

The duration of the fellowship is 1-2 years. Fellows are encouraged to concurrently consider undertaking a relevant postgraduate degree (i.e., MSc) which compliments the Fellowship. This is an academic Fellowship in which trainees are expected to conduct 1-2 research projects to publication within the field of Complex Obstetric Surgery. 

Canadian medical graduates who possess excellent surgical skills and interest with an independent CPSO license and specialist qualifications in Obstetrics and Gynaecology are encouraged to apply. Alternatively, subspecialists in Maternal Fetal Medicine may find this Fellowship an invaluable additional training opportunity to refine their skills. International medical graduates with funding support may also be considered if a local applicant is not identified, however they must be able to demonstrate outstanding surgical skills and interest through provision of case logs, activities and specific letters of reference.

Please direct all queries and completed applications to Mrs. Nancy Moniz (Program Coordinator).
