When an employee announces a pregnancy or plans to take parental leave, an employer’s obligations under Ontario’s Employment Standards Act, 2000 start well before the leave itself does. Handling pregnancy and parental leave correctly protects both the employee’s job security and the employer from a reprisal complaint down the road.
This article sets out what the ESA actually requires of an employer during and after these leaves — separate from the specific leave lengths, which are set by regulation and worth confirming directly before you rely on any particular number.
What Counts as Protected Leave
Ontario’s ESA provides eligible employees with job-protected, unpaid leave connected to pregnancy and to the birth or adoption of a child. Rather than anchoring your planning to a fixed number of weeks, treat this as a meaningful, multi-month absence, and confirm the current entitlement lengths before setting any return-to-work date in writing.
Your Core Obligations as an Employer
- Do not demand more justification than the ESA allows you to ask for. Reasonable notice and basic confirmation of the leave are appropriate; demanding detailed medical information generally is not.
- Continue any benefit plan the employee participates in, on the same basis as if they had kept working, unless the employee opts out and continues paying their share of any premiums.
- Keep crediting length of service and seniority throughout the leave, exactly as if the employee had not stopped working.
- Reinstate the employee at the end of the leave to the same position, or a comparable one if the original genuinely no longer exists, at wages no lower than what they earned before the leave began.
- Treat the leave as continuous employment for entitlements that depend on service, such as vacation accrual.
What You Cannot Do
- Terminate, lay off, or discipline an employee because they took, plan to take, or are eligible to take pregnancy or parental leave
- Threaten a reduced role or demotion for an employee planning a leave
- Treat the position as permanently filled without a real plan for reinstatement
- Pressure an employee to cut a leave short, or to delay starting one, against their wishes
These are reprisal protections, and a termination that closely follows a leave announcement will invite close scrutiny of the real reason behind it.
Pay During the Leave
The ESA does not require an employer to pay wages during pregnancy or parental leave. Income support during this period typically comes through federal Employment Insurance benefits rather than directly from the employer. Some employers choose to top up EI benefits through a formal supplemental plan — that is optional, not a legal requirement.
Planning for the Leave and the Return
Good practice includes confirming expected start and end dates in writing, agreeing on how the role will be covered while the employee is away, and checking in — without pressure — about the intended return date as it approaches. Clear, documented communication is the single best way to prevent a misunderstanding from turning into a complaint.
Coordinating With Other Types of Leave
Pregnancy and parental leave do not always stand alone. An employee may also become eligible for other ESA-protected leaves around the same period — for example, a leave connected to a family member’s illness, or a personal emergency situation unrelated to the pregnancy itself. Each type of leave has its own conditions and its own protections, so an employer should assess each request on its own terms rather than assuming one leave "uses up" or blends into another. Keeping the leaves administratively separate, with their own start and end dates documented, also makes it much easier to calculate service, benefits continuation, and the eventual reinstatement obligation correctly.
Common Employer Missteps
- Assuming an employee has forfeited their job by taking an unusually long combined leave, without checking the actual entitlement
- Filling the role permanently and treating reinstatement as optional once a suitable replacement is found
- Reducing hours, responsibilities, or pay upon an employee’s return without a legitimate, documented business reason unrelated to the leave
- Failing to keep benefit premiums current during the leave, then treating a lapse in coverage as the employee’s problem to resolve
Frequently asked questions
Can I hire a temporary replacement while an employee is on leave?
Yes, and this is common practice. Just make sure the arrangement is clearly framed as temporary and does not quietly become a substitute for reinstating the employee who is on leave.
What if the employee’s old position genuinely no longer exists when they return?
You generally need to offer a comparable position with comparable wages. Eliminating the specific role during a leave does not, by itself, eliminate the reinstatement obligation.
Does an employee have to tell me they’re pregnant before taking leave?
The ESA sets notice expectations on the employee’s side, but as the employer you should avoid demanding proof or medical details beyond what the Act allows you to ask for.
Can a small business really absorb months of an employee’s absence?
It is a genuine operational challenge, but the ESA’s leave protections do not include a small-business exemption from the reinstatement and non-reprisal obligations. Planning coverage ahead of time is the practical answer.
