Wrongful Dismissal Defence
Responding to Wrongful Dismissal Claims in Ontario
A termination dispute can quickly become costly and disruptive for an employer. A former employee may send a demand letter, challenge the termination package, allege constructive dismissal, claim additional compensation, or commence a court proceeding.
Vanguard Law advises Ontario employers responding to wrongful dismissal claims and related termination disputes. We help businesses assess legal exposure, review employment agreements and termination documentation, respond to employee demands, negotiate where appropriate, and defend claims when litigation becomes necessary.
Whether your business has recently received a demand letter or is already facing a wrongful dismissal action, early legal advice can help you understand the claim, preserve relevant records, evaluate risk and make informed decisions about next steps.
What Is a Wrongful Dismissal Claim From an Employer’s Perspective?
In Ontario, wrongful dismissal claims often arise where a former employee alleges that the employer failed to provide sufficient notice of termination or pay in lieu of notice.
Employers must consider minimum obligations under the Employment Standards Act, 2000, including termination notice or termination pay and, where applicable, statutory severance pay. Depending on the employment agreement and surrounding circumstances, an employee may also claim additional common-law reasonable notice damages.
For employers, the central questions often include:
Whether the employment agreement contains an enforceable termination clause;
Whether the termination package satisfied statutory minimum obligations;
Whether the employee may claim additional common-law notice;
Whether bonuses, commissions, benefits, incentive compensation or other amounts are in dispute;
Whether the former employee has taken reasonable steps to find replacement employment;
Whether allegations of bad faith, discrimination, reprisal, harassment or constructive dismissal are being advanced; and
Whether the matter should be negotiated, mediated or defended through litigation.
Vanguard Law helps Ontario employers assess these issues practically and develop a response strategy suited to the business, the documents and the claim.
ESA Minimums, Employment Contracts and Common-Law Exposure
Ontario employers must comply with minimum statutory termination obligations. However, meeting minimum statutory requirements does not always resolve the dispute. A former employee may claim entitlement to greater compensation under common law unless a legally enforceable employment agreement limits those entitlements.
An employer’s defence may therefore depend significantly on the wording of the employment agreement, the termination letter, payroll and benefits records, compensation terms, workplace policies and the circumstances surrounding the dismissal.
We assist employers with reviewing:
Employment agreements and termination clauses;
Offer letters and compensation arrangements;
Termination letters and severance packages;
Bonus, commission and incentive-plan language;
Benefits continuation and vacation pay issues;
Performance-management and disciplinary records;
Workplace policies and investigation materials; and
Communications with the former employee before and after termination.
Where a dispute exposes weaknesses in existing employment documents, policies or termination procedures, employers may also benefit from ongoing employment-law support through Workplace Counsel+™.
Common Wrongful Dismissal Defence Matters We Handle
Demand Letters From Former Employees
A demand letter may allege that the employee was underpaid on termination, challenge an employment agreement, claim additional notice damages, or raise allegations about how the dismissal occurred.
Employers should avoid responding impulsively or making admissions before the allegations and underlying documents have been reviewed. We help employers assess the demand, understand potential exposure, identify available arguments and prepare an appropriate response.
Court Claims and Wrongful Dismissal Litigation
Where a former employee starts a wrongful dismissal proceeding, employers need timely advice on the claim, applicable deadlines, evidence preservation and defence strategy.
We assist with defending claims involving notice, termination pay, statutory severance, common-law damages, benefits, bonuses, commissions, mitigation, employment contracts and allegations of bad faith conduct.
Employment Agreements and Termination Clauses
A properly drafted employment agreement may materially affect an employer’s potential liability when employment ends. However, termination clauses must be carefully reviewed before an employer relies on them.
We assess whether the agreement may support the employer’s position, whether statutory obligations were satisfied and whether contractual language may be challenged by the former employee.
Employers seeking to improve employment agreements and reduce future termination risk can also learn more about our ongoing employer-side support through Workplace Counsel+™.
Bonus, Commission and Benefits Disputes
Wrongful dismissal claims frequently involve more than base salary. A former employee may seek compensation for bonuses, commissions, benefits, incentive payments, equity-related compensation or other remuneration alleged to have been lost during the notice period.
We review the governing documents, employment terms and compensation history to help employers assess these claims and respond appropriately.
Mitigation and Post-Termination Earnings
A former employee claiming wrongful dismissal damages may have obligations relating to the search for comparable employment. Replacement income or issues relating to mitigation can become relevant to an employer’s defence.
We help employers identify when mitigation evidence may matter and how it can appropriately be addressed in negotiations or litigation.
Constructive Dismissal Allegations
An employee may allege constructive dismissal where the employer made a significant unilateral change to compensation, duties, title, reporting structure, hours, location or working conditions.
These claims can arise even where the employer did not intend to terminate employment. We assist businesses with assessing constructive dismissal allegations and responding to claims arising from workplace changes, restructuring or disputed employment decisions.
Termination for Cause Allegations
Some employers face claims after taking the position that an employee was terminated for serious misconduct. Cause is a fact-specific and demanding legal position, and an unsuccessful cause allegation may create additional risk.
We help employers assess the evidence, relevant workplace policies, investigation history and communications before determining how a cause-based position should be addressed or defended.
Human Rights, Harassment and Reprisal Allegations
Wrongful dismissal disputes may overlap with allegations of discrimination, disability-related issues, accommodation failures, workplace harassment, reprisal or a poisoned work environment.
Where a termination dispute involves workplace misconduct allegations or a complaint requiring investigation, employers may also require assistance with a workplace investigation.
Restructuring, Layoffs and Group Terminations
Business changes may lead to terminations, temporary layoffs, restructuring or the elimination of positions. These decisions can trigger individual or multiple employee claims if not planned and documented properly.
We advise Ontario employers on disputes arising from restructuring decisions, termination packages, employment agreements and allegations that workplace changes amounted to dismissal.
What Should an Employer Do After Receiving a Wrongful Dismissal Demand Letter or Claim?
Employers receiving a wrongful dismissal demand should act promptly and carefully. Early steps may affect the business’s legal position, settlement options and ability to defend the matter effectively.
Practical initial steps often include:
Preserving the employee’s employment agreement, payroll records, benefits information, termination documents and relevant communications;
Avoiding informal responses or admissions before obtaining legal advice;
Identifying whether any response deadline, court deadline or settlement deadline applies;
Reviewing the termination package and amounts already paid or offered;
Confirming whether allegations extend beyond notice or severance, including human rights, harassment, reprisal or bad faith claims; and
Obtaining advice on whether the claim should be negotiated, mediated or defended.
Vanguard Law helps employers organize the relevant information, understand the issues being raised and determine an appropriate response.

Frequently Asked Questions for Ontario Employers
What Should We Do After Receiving a Demand Letter From a Former Employee?
Do not ignore the demand, but avoid responding impulsively before the allegations and relevant employment documents have been reviewed. Employers should preserve records, identify any deadlines and obtain advice about exposure and response options.
Does an Employer Always Have to Pay What the Employee Demands?
No. A demand letter reflects the former employee’s position, not necessarily the amount legally owed. An employer may have arguments relating to the employment agreement, statutory compliance, reasonable notice, compensation terms, mitigation, replacement earnings or the circumstances of termination.
Can an Employment Agreement Limit Wrongful Dismissal Exposure?
An employment agreement may affect the employee’s termination entitlements if its termination provisions are legally enforceable and comply with applicable statutory requirements. The agreement should be reviewed carefully before an employer relies on it in response to a claim.
What if We Already Offered the Employee a Termination Package?
The termination package is an important starting point, but a former employee may allege that it was insufficient. We can review the package, the employment agreement and the employee’s allegations to help assess whether additional exposure exists and how the employer should respond.
Can a Former Employee Claim Bonuses, Commissions or Benefits?
Potentially. Claims may include compensation beyond base salary, depending on the employment terms, governing plans, past compensation and the period for which damages are claimed. Employers should have these documents reviewed when responding to a demand.
What if the Employee Claims Constructive Dismissal?
Constructive dismissal allegations may arise where an employee claims the employer fundamentally changed the employment relationship without agreement. The employer’s response will depend on the actual changes made, the documents, communications and surrounding circumstances.
What if the Employee Alleges Discrimination, Harassment or Reprisal?
A wrongful dismissal matter may overlap with other legal allegations, including human rights or workplace misconduct issues. These claims should be assessed promptly, particularly where an investigation, accommodation history or complaint process may be relevant. Employers dealing with internal complaints or misconduct allegations can also review our Workplace Investigations service.
Can We Reduce the Risk of Future Wrongful Dismissal Disputes?
Not every dispute can be prevented, but appropriate employment agreements, termination planning, policies, documentation and timely advice can help businesses manage risk. Employers seeking ongoing employment-law support can learn more about Workplace Counsel+™.
