Pregnancy and Parental Leave: Your Job Protection Rights in Ontario

The Statutory Framework

Ontario's Employment Standards Act, 2000 (ESA) provides two distinct but related leave entitlements: pregnancy leave and parental leave.

Pregnancy Leave

Under section 46 of the ESA, a pregnant employee who has been employed for at least 13 weeks before the expected date of birth is entitled to pregnancy leave of up to 17 weeks. The leave can begin no earlier than 17 weeks before the expected date of birth and no later than on the date of birth.

The employee must provide the employer with at least two weeks' written notice before the start of the leave. If the employee stops working because of a complication or condition related to the pregnancy before the leave was scheduled to begin, the notice requirement is modified — the employee must provide written notice as soon as possible.

Pregnancy leave ends 17 weeks after it began, or on an earlier date if the employee gives the employer at least four weeks' written notice of the earlier return date.

Parental Leave

Under section 49 of the ESA, an employee who has been employed for at least 13 weeks and who is a parent of a child is entitled to parental leave. The duration depends on whether the employee also took pregnancy leave:

• An employee who took pregnancy leave is entitled to up to 61 weeks of parental leave.
• An employee who did not take pregnancy leave is entitled to up to 63 weeks of parental leave.

Parental leave is available to birth parents, adoptive parents, and parents in a relationship of some permanence with the birth or adoptive parent. The leave must begin within 78 weeks of the child's birth or the date the child first came into the employee's custody, care, and control.

Combined Duration

An employee who takes both pregnancy leave (17 weeks) and parental leave (61 weeks) receives a combined total of 78 weeks of job-protected leave — approximately 18 months. This aligns with the maximum duration of Employment Insurance parental benefits under the extended option.

Job Protection: The Right to Return

The most important protection in the ESA's leave provisions is the right to return to the same position — or a comparable position — when the leave ends.

The Reinstatement Right

Section 53 of the ESA provides that when an employee's pregnancy or parental leave ends, the employer must reinstate the employee to the position the employee most recently held, if it still exists, or to a comparable position, if the original position no longer exists.

"Comparable position" means a position that is comparable to the position the employee held before the leave in terms of responsibilities, wages, benefits, and location. A comparable position is not a demotion, a lateral move to a less desirable role, or a reassignment to a different location.

The Exception: Reasons Unrelated to Leave

The ESA provides an exception: the employer is not required to reinstate the employee if the employer has been discontinued. But the employer cannot refuse reinstatement for reasons related to the leave. The termination of an employee on pregnancy or parental leave is permitted only if the termination is for reasons unrelated to the leave — a genuine restructuring, a business closure, or a for-cause termination based on misconduct that occurred before the leave.

The "reasons unrelated to the leave" exception is narrow, and courts and the Ministry of Labour scrutinize it carefully. An employer that eliminates only the position of the employee on leave — while retaining other positions — faces a strong inference that the elimination was related to the leave. An employer that restructures an entire department, eliminating multiple positions including that of the employee on leave, has a stronger argument that the elimination was unrelated.

The Anti-Retaliation Protections

ESA Protections

Section 74 of the ESA prohibits employers from intimidating, dismissing, penalizing, or otherwise retaliating against an employee for exercising or attempting to exercise their rights under the ESA — including the right to take pregnancy and parental leave. The prohibition covers termination during or shortly after leave, demotion or reduction in responsibilities upon return, reduction in compensation or benefits, negative performance consequences related to the leave, and any other adverse action that is connected to the exercise of leave rights.

Human Rights Code Protections

The Ontario Human Rights Code provides additional and overlapping protections. Discrimination on the basis of sex includes discrimination on the basis of pregnancy (section 10(2)), and the duty to accommodate extends to pregnancy-related needs. An employer that terminates an employee because of pregnancy, or that refuses to accommodate pregnancy-related limitations, violates the Human Rights Code.

The Human Rights Tribunal of Ontario has awarded significant damages in cases involving pregnancy-related discrimination. Awards for general damages (injury to dignity, feelings, and self-respect) in pregnancy discrimination cases have ranged from $15,000 to $50,000 or more, depending on the egregiousness of the employer's conduct.

Common Employer Violations

Despite the clear statutory protections, violations are common. The most frequent patterns include:

Termination during leave. The employer restructures during the employee's leave and eliminates the employee's position. The employer claims the restructuring was unrelated to the leave. The timing is suspicious — the restructuring coincides with the leave, and no other positions were eliminated.

Demotion upon return. The employee returns from leave to find that their responsibilities have been reassigned, their title has changed, or they have been moved to a less desirable role. The employer characterizes the change as a "business need" rather than a demotion.

Constructive dismissal upon return. The employer makes the employee's working conditions intolerable upon return — assigning them to a different shift, reducing their authority, excluding them from meetings, or otherwise signalling that they are no longer valued. The employee, unable to continue under these conditions, resigns — which is what the employer intended.

Failure to continue benefits. During pregnancy and parental leave, the employer must continue to pay its share of the premiums for benefit plans (health insurance, dental insurance, life insurance, etc.) in which the employee was enrolled before the leave. Some employers stop these contributions during the leave, which violates the ESA.

Performance concerns that surface post-announcement. The employer has no documented performance concerns before the employee announces their pregnancy. After the announcement — or after the leave begins — performance issues suddenly appear. The timing suggests that the performance concerns are pretextual.

Your Rights During Leave

During pregnancy and parental leave, you continue to be an employee of the employer. This means:

Seniority and service continue to accrue. Your length of service is not interrupted by the leave. If your employer provides benefits or entitlements based on length of service (vacation entitlement, pension vesting, severance eligibility), the leave period counts toward your service.

Benefits continue. The employer must continue to pay its share of benefit plan premiums. You must continue to pay your share (if any). If you fail to pay your share, the employer can discontinue your participation in the plan — but must reinstate it when you return.

You cannot be terminated because of the leave. The employer can terminate you during leave only for reasons genuinely unrelated to the leave. The burden of proving that the reasons are unrelated falls heavily on the employer.

Pension and credit accumulation. Under pension plans and similar benefit plans, the leave period should count as service for vesting and accumulation purposes, to the extent required by the specific plan and by the ESA.

Employment Insurance

Pregnancy and parental leave are unpaid under the ESA. Financial support during the leave comes from the Employment Insurance (EI) system:

Maternity benefits. Up to 15 weeks of EI maternity benefits are available to the birth parent, at 55 percent of average insurable weekly earnings (up to the maximum insurable earnings ceiling, which is $668 per week in 2025).

Parental benefits. EI parental benefits are available in two options: the standard option provides up to 35 weeks of benefits at 55 percent of average insurable earnings, and the extended option provides up to 61 weeks of benefits at 33 percent of average insurable earnings.

The combined maximum under the standard option is 50 weeks (15 weeks maternity + 35 weeks parental). Under the extended option, it is 76 weeks (15 weeks maternity + 61 weeks parental).

Parental benefits can be shared between two parents. Under the standard option, a five-week sharing bonus is available when both parents take at least five weeks of parental leave.

Practical Guidance

Notify your employer in writing. Provide written notice of your intention to take leave, specifying the expected start date. Keep a copy for your records.

Document your role before leave. Before your leave begins, document your current responsibilities, reporting relationships, title, compensation, and benefits. This documentation is essential if you return to find that your role has changed.

Stay in contact. While you are not required to work during leave, maintaining some contact with your employer (responding to administrative queries, checking in periodically) can prevent the out-of-sight-out-of-mind dynamic that sometimes leads to leave-related violations.

Provide return notice. Give your employer at least four weeks' written notice before your planned return date. This triggers the reinstatement obligation and gives the employer time to prepare.

Assert your rights immediately. If you return from leave and find that your role has been changed, your responsibilities have been reassigned, or your position has been eliminated, raise the issue immediately — in writing. State that you expect to be reinstated to your previous position (or a comparable one) as required by the ESA.

File a complaint if necessary. If your employer refuses to reinstate you, demotes you, or otherwise retaliates, file a complaint with the Ministry of Labour (for ESA violations) or an application with the Human Rights Tribunal (for discrimination). Do not accept the situation as permanent without exploring your legal options.

The protections for pregnancy and parental leave are among the strongest in Ontario employment law. They exist because the alternative — forcing employees to choose between having children and having careers — is both unjust and economically destructive. Use them. Assert them. And enforce them if necessary.
