Can an Employer Reverse a Termination in Ontario?
Being let go is often a defining moment in an employment relationship. A termination meeting happens, a letter is handed over, access is cut off, and the employee begins making decisions about their finances, family, job search, and legal rights.
But what happens if the employer changes its mind?
Maybe the employer says the termination was a mistake. Maybe HR realizes the severance package was mishandled. Maybe the employer wants the employee back after learning that the termination may expose the business to a wrongful dismissal claim.
So, can an employer in Ontario reverse a termination?
The short answer: usually not unilaterally. In most cases, once a clear termination has been communicated, the employer cannot simply “take it back” unless the employee agrees.
That does not mean an employee can always refuse a return-to-work offer without consequences. Ontario employment law draws an important distinction between reversing the termination and offering re-employment as mitigation.
The General Rule: A Termination Cannot Usually Be Withdrawn Without Consent
Ontario’s employment standards guidance is clear: once notice of termination or resignation has been given, it generally cannot be withdrawn unless the other party consents. The Employment Standards Act Policy and Interpretation Manual explains that the party receiving the notice may have acted, or may be expected to act, in reliance on it.
That makes practical sense.
Once an employee is told they are fired, they may:
Start applying for other jobs
Speak with recruiters
Tell family members and colleagues
Consider relocating
Apply for Employment Insurance
Review or negotiate a severance package
Seek legal advice
Make financial decisions based on the loss of income
The law does not usually allow the employer to erase that moment after the fact simply because the employer regrets the decision.
What Counts as a Real Termination?
Not every emotional workplace comment is necessarily a legal termination. Context matters.
A clear termination may include:
A written termination letter
A meeting where the employee is told their employment is ending
Removal from payroll or systems
A final pay or severance offer
Instructions to return company property
A Record of Employment indicating dismissal or shortage of work
A statement that the decision is final
The more formal and deliberate the communication, the harder it becomes for the employer to argue that there was no real termination.
By contrast, the law may treat certain statements differently if they are made in the heat of the moment and quickly withdrawn. For example, if a manager blurts out “you’re fired” during an argument but immediately retracts it, the legal analysis may be different. The issue is whether a reasonable person would understand that the employment relationship was actually being brought to an end.
What if the Employer Says It Was a Mistake?
Employers sometimes try to reverse a termination by saying:
“We made a mistake.”
“You were not actually terminated.”
“We are rescinding the termination.”
“Please return to work on Monday.”
“We are withdrawing your termination letter.”
Those words may not be enough.
If the employee was clearly terminated, the employer generally needs the employee’s consent to undo it. The employee may agree to return, negotiate new terms, or reject the offer and pursue their legal entitlements.
That said, employees should be careful before refusing. A refusal may raise mitigation issues, discussed below.
Reversal vs. Re-Employment: The Key Difference
There are two different concepts that often get blurred together.
The first is a true reversal of the termination. This means the parties agree that the termination will be undone and the employment relationship will continue.
The second is an offer of re-employment. This means the employer has terminated the employee but is now offering work to reduce or eliminate the employee’s claimed losses.
The difference matters.
An employer may not be able to force the employee to accept that the termination never happened. However, the employer may still argue that the employee had a duty to reduce their losses by accepting a reasonable return-to-work offer.
The Mitigation Issue: Do You Have to Go Back?
In wrongful dismissal cases, employees generally have a duty to mitigate their damages. That means they must take reasonable steps to reduce their losses, usually by looking for comparable work.
The Supreme Court of Canada considered this issue in Evans v. Teamsters Local Union No. 31. The Court confirmed that, in some circumstances, a dismissed employee may be required to mitigate by returning to work for the same employer.
But this is not automatic.
The key question is whether a reasonable person in the employee’s position would accept the offer. Factors may include:
Whether the role is comparable
Whether pay, benefits, seniority, and duties are preserved
Whether the work environment is hostile, humiliating, or poisoned
Whether the employee was treated fairly during the termination
Whether the offer is temporary or permanent
Whether the employer is asking the employee to sign new terms
Whether returning would undermine the employee’s dignity or legal position
For example, if the employer offers the same job, same pay, same benefits, and a respectful return-to-work plan, refusing may be risky.
On the other hand, if the employer fired the employee in a humiliating way, accused them of misconduct, cut their pay, changed their role, or created a toxic workplace, the employee may have stronger reasons to refuse.
This is highly fact-specific. Before responding, employees should consider getting advice from an Ontario employment lawyer.
Can the Employer Make You Sign Something to Come Back?
Sometimes an employer will offer to reverse the termination only if the employee signs a new agreement, release, probationary clause, restrictive covenant, or modified termination clause.
That can be dangerous.
If an employee signs new documents without legal advice, they may accidentally give up valuable rights, including rights to common law notice, bonuses, commissions, benefits, equity, or claims arising from the termination.
This is especially important where the employer uses the return-to-work offer to pressure the employee into accepting worse terms. A major change to pay, duties, status, location, or working conditions may also raise constructive dismissal concerns.
What if the Employee Wants to Go Back?
Some employees want their job back. That is understandable, especially where the employee enjoyed the work, needs income stability, or believes the termination was a misunderstanding.
If you are considering returning, try to get the terms in writing. Important issues include:
Is the termination being fully withdrawn by agreement?
Will service be treated as continuous?
Will pay, benefits, vacation, bonus, commission, and pension rights continue uninterrupted?
Will the Record of Employment be corrected?
Will the employer confirm there is no discipline on file?
Are you being asked to sign a release or new employment agreement?
Will any legal fees or lost wages be addressed?
What happens if the employer terminates again shortly after you return?
A return to work can be a good outcome, but only if the terms are clear.
What if the Employer Gave Working Notice?
Working notice means the employee continues working until a future termination date. Under Ontario’s Employment Standards Act, 2000, employers have minimum obligations when terminating eligible employees, including notice or pay in lieu. During the statutory notice period, the ESA also restricts changes to wages and employment terms and requires benefit continuation.
If an employer gives working notice and later wants the employee to stay permanently, that should be clearly documented. The employee may agree, but the employer should not assume that a previously issued termination notice simply disappears without consent.
What Employees Should Do if the Employer Tries to Reverse the Termination
If your employer terminated you and then tried to take it back, do not respond impulsively.
Consider these steps:
Save all documents. Keep the termination letter, emails, texts, severance offer, Record of Employment, and return-to-work communications.
Do not sign immediately. A return-to-work offer may include new terms, releases, or limits on your rights.
Ask for the offer in writing. Verbal assurances are difficult to prove later.
Consider whether the return is reasonable. Look at pay, duties, reporting relationships, workplace atmosphere, benefits, and dignity.
Get advice before refusing. A refusal may affect your severance claim if the employer later argues you failed to mitigate.
Get advice before accepting. Returning without clear terms may create confusion about your rights.
Vanguard Law regularly helps employees assess termination letters, return-to-work offers, severance packages, and mitigation risks. If you have been dismissed and your employer is trying to reverse course, a severance package review can help you understand the best next step.
What Employers Should Do Before Trying to Reverse a Termination
Employers should also be careful. A rushed attempt to “undo” a termination can create more risk, not less.
Before contacting the employee, employers should assess:
Was the termination clearly communicated?
Was the termination effective immediately or on a future date?
Has the employee already relied on the termination?
Are you offering the same job or different terms?
Are there human rights, reprisal, disability, harassment, or accommodation issues?
Could the return-to-work offer be seen as pressure or bad faith?
Should the offer be framed as mitigation rather than rescission?
Employers dealing with a potential claim should get legal advice before sending a rescission letter, return-to-work offer, or demand response. Vanguard Law assists employers with wrongful dismissal defence and termination strategy across Ontario.
Bottom Line
In Ontario, an employer usually cannot fire an employee and then unilaterally reverse the termination as if nothing happened. Once a clear termination has been communicated, the employer generally needs the employee’s consent to undo it.
But that is not the end of the analysis. If the employer offers the employee their job back, the employee may need to consider whether accepting the offer is a reasonable way to mitigate losses. Refusing a reasonable return-to-work offer can sometimes reduce a wrongful dismissal claim.
The safest approach is to pause, get the offer in writing, and obtain legal advice before accepting, rejecting, or negotiating the return.
If you have been let go and your employer is now trying to reverse the decision, contact Vanguard Law before you sign anything or agree to return.
