All pregnant employees are entitled to up to 17 weeks of unpaid leave under the Ontario Employment Standards Act. In some circumstances, this leave may be extended.
What is the difference between parental leave and maternity leave in Ontario?

Birth parents.
Adoptive parents.
A person in a relationship with a parent of a child who will treat the child as their own.
Birth mothers who take pregnancy leave are entitled to up to 61 weeks of parental leave.

The ESA stipulates that employees must have worked in your organization for a minimum of 13 weeks prior to the date the baby is expected to be born.
