According to the Maternity Experiences Survey, the vast majority – 95% of women – had their first prenatal visit in the first trimester.

On average, Canadian women had their first prenatal visit at 7.5 weeks gestation. That varied between the provinces and territories – from 6.4 in British Columbia to 9.2 in Québec.


Prenatal care is important for the health of the mother, as well as for the fetus and infant. It is likely to be most effective if women begin their prenatal care early – in the first trimester – and continue it at regular intervals throughout their pregnancy.  The quality of care – that is what happens in each visit – is also important.1
