The Ontario Ministry of Health and Long Term Care currently funds prenatal screening for Down syndrome and trisomy 18 for all pregnant persons who want this testing.

These services are provided through primary health practitioners (midwives, family doctors and obstetricians). More detailed information is available through the 18 Ontario regional genetics centres. Health care providers can refer pregnant persons to these centres when indicated.

The Prenatal Screening Subcommittee of Ontario has developed this website to provide information to both health care providers and pregnant persons on prenatal screening currently offered in Ontario. There are several links on the website that are not currently active. These links will become active as the work of the Subcommittee evolves into these areas.
