PSO is housed within the province’s maternal, newborn and child registry, the Better Outcomes Registry and Network (BORN) Ontario. BORN Ontario is a prescribed registry established in Ontario under the Personal Health Information Protection Act, 2004 (PHIPA) for the purpose of facilitating and/or improving the provision of health care in our province, with a vision for the best possible beginnings for lifelong health. PSO operates within BORN Ontario’s policies and procedures, including those related to data privacy and security. For more information, please see BORN Ontario’s Data Privacy and Security and the BORN Ontario's Privacy FAQs.

With the launch of the Ontario Maternal Serum Screening Program in 1993, a framework for a system of prenatal screening in Ontario was established. The subsequent introduction of nuchal translucency (NT) screening and the shift of serum screening to the hospitals allowed the system to transition from a pilot project to a province-wide initiative in 2003. Over the years, participating laboratories and clinical experts regularly met to support the ongoing provision of high-quality screening in Ontario. In 2016, the Provincial Council for Maternal and Child Health (PCMCH) struck a Prenatal Screening Strategy Task Force, which submitted recommendations to the Ministry of Health and Long-Term Care (MOHLTC) outlining the essential principles for a provincial prenatal screening strategy.

In 2017, the Provincial Budget announced that “Ontario is…investing in the creation of a provincial prenatal screening program that will enhance access to standardize and high-quality prenatal screening across the province”; Prenatal Screening Ontario was launched and has been in full operations since 2018.

The PSO team is a dedicated, experienced group of individuals committed to the support of high-quality prenatal screening for families in Ontario.

The PSO team consists of:

• Medical Directors (MFM/Geneticist)
• Program Manager
• Genetic Counsellors
• Clinical Content Specialist (Ultrasound)
• Epidemiologist
• Data Analysts
• Administrative Staff

The work of PSO is best supported by the input of those who have experience with prenatal screening, as a practitioner, patient or family member.
