Section 204 — Canada Labour Code: Reassignment and job modification

An employee who is pregnant or nursing may, during the period from the beginning of the pregnancy to the end of the twenty-fourth week following the birth, request the employer to modify her job functions or reassign her to another job if, by reason of the pregnancy or nursing, continuing any of her current job functions may pose a risk to her health or to that of the foetus or child. An employee’s request under subsection (1) must be accompanied by a certificate from a health care practitioner of the employee’s choice indicating the expected duration of the potential risk and the activities or conditions to avoid in order to eliminate the risk.
