This examines the perceptions of interprofessional collaboration from the perspectives of midwives and obstetricians, and contrasts how these perceptions vary by the profession. Data was collected in two ways: through an online survey and semistructured interviews. Midwives and obstetricians were asked about their experiences with collaboration, their perspectives on the barriers to collaboration and thoughts about an improved system in Ontario to facilitate enhanced maternity care collaboration. The results demonstrate the key barriers to collaboration including contentious views on scope of practice, the definition and interpretation of interprofessional collaboration and varying philosophies of care. The changing landscape of maternity care in Ontario is imminent; family doctors who provide obstetrical care are on the decline, increasing the workload for obstetricians and midwives necessitating the need to eliminate barriers to achieve successful interprofessional collaboration.
