Fired While on Maternity or Parental Leave in Ontario

10 Jun 2026 4 min read No comments Wrongful Dismissal & Severance Ontario
💡

If you are fired while on maternity or parental leave in Ontario, the Employment Standards Act (ESA) creates a strict presumption of reprisal. The employer bears the burden to prove the termination was for a completely unrelated reason, such as a genuine corporate bankruptcy. Otherwise, you may be legally entitled to reinstatement, lost wages, and substantial common law severance pay.

Returning from a parental leave should be a smooth, welcoming transition back into the workforce after spending valuable time with your new child. 👪 Unfortunately, a shocking number of parents in Ontario discover that their job has been quietly given to a replacement worker, or their position has supposedly been “eliminated” while they were away.

Being fired during a vulnerable statutory leave is not just unethical-it is heavily regulated by provincial law. The legal protections in place are designed specifically to ensure that starting a family does not completely derail your hard-earned career.

Your Rights Under the Employment Standards Act (ESA)

In Ontario, the ESA provides highly specific job protections for workers on approved statutory leaves, such as pregnancy and parental leave. 📈 When your official leave ends, your employer is legally mandated to reinstate you to the exact same position you held before. If that specific position genuinely no longer exists, they must offer you a comparable role with equal pay, benefits, and seniority.

If an employer in Toronto, Vaughan, Markham, or Burlington fires you during your leave, the law automatically assumes they are illegally penalizing you for taking time off. This is known legally as a “presumption of reprisal.” The burden of proof shifts entirely onto the employer’s shoulders to show that the termination was completely unrelated to your parental leave.

When Can an Employer Legally Dismiss You?

An employer can only legally terminate an employee on maternity leave if there is a legitimate business reason that would have definitively resulted in the dismissal even if the employee had never taken leave. 💼 Concrete examples include a complete company bankruptcy, the closure of an entire branch, or a massive structural downsizing affecting a large percentage of staff members.

Step-by-Step Process to Protect Your Rights in Ontario

Step 1: Request Written Reasons for Termination

If you are abruptly informed of your termination over a phone call or a brief Zoom meeting, politely demand that the employer provide the precise reasons in writing. 🗒 Do not simply accept vague verbal excuses about “changing business needs.” Written documentation will serve as critical evidence for your legal counsel.

Step 2: Do Not Sign a Release Immediately

Employers frequently try to offer a standard severance package heavily disguised as a generous exit offer, pressuring you with an artificial deadline. Signing a full and final release completely waives your right to pursue human rights damages or file Ministry of Labour complaints. Always have a lawyer review it first.

Step 3: Pursue Legal Action via OLRB or Superior Court of Justice

If the dismissal was unjust, you generally choose between filing a formal complaint with the Ontario Labour Relations Board (OLRB) for reprisal, or filing a civil lawsuit at the Superior Court of Justice. A local employment law firm in Ottawa, London, or Mississauga can meticulously evaluate your case to decide which path yields the maximum financial compensation.

How Much Does It Cost in Ontario?

Fighting back against a wrongful dismissal during a parental leave requires an understanding of the potential legal fees.

Legal PathTypical Costs (CAD)
Ministry of Labour / OLRB ClaimThere are no government filing fees. You can represent yourself, but hiring a lawyer for guidance usually costs an hourly rate of $300 to $700 CAD.
Superior Court LawsuitInitial court filing fees are around $229 CAD. Lawyers typically operate on a contingency basis, taking 25% to 35% of the total settlement.
Demand Letter / NegotiationSome lawyers charge a flat fee of $1,500 to $3,000 CAD to draft a strong demand letter and conduct preliminary negotiations.

How Long Does the Process Take?

The timeline for resolving maternity leave dismissal cases heavily depends on the employer’s legal strategy. 🕐 A well-drafted demand letter from a reputable law firm can sometimes force an employer to settle and pay adequate severance within 2 to 4 months. If you must proceed with litigation at the Superior Court of Justice or a formal hearing at the OLRB, the process can easily stretch to 1.5 to 2.5 years.

Frequently Asked Questions (FAQ)

What if they offer me a different job with a pay cut?

You generally do not have to accept a substantially lesser role. If your original job no longer exists, the ESA strictly requires the employer to provide a comparable role with equal pay. A significant reduction in pay, status, or duties could be legally considered constructive dismissal.

Can I be fired if the maternity cover was better at the job?

Absolutely not. It is entirely illegal in Ontario to fire you or refuse reinstatement simply because the employer personally prefers the performance of the contract worker they hired to cover your temporary absence.

Will taking a longer 18-month leave hurt my legal rights?

No. Whether you elect to take the standard 12-month leave or the extended 18-month parental leave under federal EI rules, your provincial job protection rights under the Ontario ESA remain exactly the same.

Do I need a lawyer to file an ESA complaint?

You are not strictly required to have a lawyer to file a basic Ministry of Labour complaint. However, consulting a law firm before choosing between the Ministry and the Superior Court of Justice is absolutely crucial, as you legally cannot pursue both avenues simultaneously for the same termination.
