Can an Ontario Employer Retract a Notice of Termination Once Given?

10 Jun 2026 5 min read No comments Wrongful Dismissal & Severance Ontario
💡

In Ontario, once an employer gives a clear and unequivocal notice of termination, they generally cannot legally retract it without the employee’s consent. If the company changes its mind and asks you to stay, you usually have the right to refuse, treat your employment as officially terminated, and demand your full severance pay. Filing a claim to enforce this can be done in the Ontario civil courts.

Business decisions are sometimes made in haste. A company in Mississauga might lose a major client and immediately lay off a department, only for the client to return two days later. The employer panics, calls the fired employees, and says, “We made a mistake, your termination is cancelled, come back to work on Monday.” 😲 Many workers assume they have no choice but to return, fearing that if they refuse, they will be considered to have “resigned” and will lose their severance.

Employment law in Ontario views the employment relationship as a binding contract. A notice of termination is a formal break of that contract. The Superior Court of Justice has repeatedly ruled that a termination is not a two-way street; an employer cannot unilaterally withdraw a dismissal once it is communicated clearly to the employee. Whether you are a retail worker in Hamilton or a software engineer in Toronto, if your employer tries to take back a termination, you hold the cards. However, you must carefully navigate your legal “duty to mitigate” before simply walking away.

Step-by-Step Process When an Employer Retracts a Firing

If your employer tries to un-fire you, your response must be strategic. Handling this situation incorrectly could inadvertently cost you your severance package. 📋

Step 1: Analyze the Original Notice of Termination

Was the firing official? For a notice to be binding in Ontario, it must be clear and unequivocal. If a manager yelled “You’re fired!” in a fit of rage and apologized five minutes later, a court might not view that as a true termination. However, if you received a formal termination letter from HR, the dismissal is legally crystallized.

Step 2: Assess the Offer to Return

If they ask you back, closely examine the offer. 📄 Is it the exact same position, with the same salary, same hours, and the same reporting structure? If the employer asks you to return but to a lesser role or with lower pay, this is considered a constructive dismissal. You have every right to reject a lesser offer and pursue your severance.

Step 3: Consider Your Duty to Mitigate

This is the trickiest legal aspect. In Ontario, wrongfully dismissed employees must “mitigate their damages” by looking for similar work. If your employer offers your exact job back, and the relationship is not toxic or poisoned, a judge might decide that a reasonable person would accept the job to avoid losing income. If you refuse an identical job without a good reason (like a hostile work environment), the court could severely reduce your severance award.

Step 4: Formulate a Written Response

Do not simply ignore the employer’s emails or phone calls. ✉️ You must formally respond. If you are refusing to return because the environment is poisoned or the trust is irreparably broken, state this clearly in writing. A skilled employment lawyer should draft this correspondence to ensure you do not accidentally resign.

Step 5: Proceed with Legal Action if Severance is Withheld

If you rightfully refuse to return and the employer refuses to pay your severance out of spite, your legal team will issue a Statement of Claim. For severance amounts under $35,000 CAD, the process takes place in the Ontario Small Claims Court. Larger claims will proceed to the Superior Court of Justice.

How Much Does it Cost in Ontario?

Securing your severance after a retracted termination is highly viable. 💰 Here are the typical legal and administrative costs:

  • Lawyer Consultation & Strategy: Having an employment lawyer assess the retraction offer and draft your formal refusal letter typically costs between $500 and $1,200 CAD.
  • Contingency Representation: If a lawsuit is required, most employee-side law firms take the case on contingency, retaining 25% to 33% of the final severance settlement won.
  • Court Filing Fees: Filing a claim at the Small Claims Court is approximately $108 CAD, while the Superior Court of Justice charges roughly $229 CAD to issue a claim.

How Long Does the Process Take?

Resolving a retracted termination dispute depends on how stubborn the employer is regarding your refusal to return.

  • Responding to the Offer: You generally have a few days to a week to formally accept or reject the employer’s offer to return.
  • Private Settlement: After a lawyer sends a demand letter explaining why you will not return and demanding severance, a settlement is often reached within 3 to 5 weeks.
  • Court Litigation: If the employer fights you, a resolution through the Ontario court system can take 8 to 14 months.

Frequently Asked Questions (FAQ)

What constitutes a “poisoned work environment” if I refuse to return?

A poisoned environment means the workplace is so hostile, humiliating, or toxic that a reasonable person could not be expected to work there. If the termination was accompanied by yelling, public humiliation, or discrimination, you have a very strong case to refuse returning without losing your severance.

If I agree to return, does my seniority reset?

No. If you agree to the retraction and return to work, your employment is considered continuous. Your years of service, vacation entitlements, and future severance rights remain fully intact as if the termination notice never happened.

Can an employer give me “working notice” and then cancel it?

No. If an employer gives you 8 weeks of working notice, the termination date is set. They cannot wait until week 7 and say, “Never mind, we need you to stay permanently.” You have the right to leave on the scheduled termination date.

Will refusing to return affect my Employment Insurance (EI)?

It might. Service Canada requires you to accept reasonable employment. If your employer officially offers your job back and you refuse, the employer might inform Service Canada, which could delay or deny your EI benefits while they investigate if your refusal was justified.
