Wrongful Dismissal Litigation and How to Avoid It
In Ontario, wrongful dismissal claims are among the most common employment law disputes. Employers can face significant financial and reputational consequences if a termination is handled improperly.
With rising awareness of workplace rights and shifting legal standards, avoiding wrongful dismissal litigation has become a key part of risk management for every organization.
This article explains what wrongful dismissal means in Ontario, common mistakes employers make, and practical steps to prevent disputes with insights from employment lawyers experienced in wrongful termination defence and litigation.
What Is Wrongful Dismissal in Ontario?
A wrongful dismissal occurs when an employee is terminated without reasonable notice, pay in lieu, or just cause under Ontario law. Even when an employer believes they are acting fairly, a court may find the dismissal wrongful if the termination didn’t comply with:
- The Employment Standards Act, 2000 (ESA) minimum notice and severance requirements; or
- The common law typically provides much longer notice periods.
Employees who believe they were wrongfully dismissed can file a claim or start a civil action seeking compensation, sometimes for several months or even years of lost pay.
Why Employers Face Wrongful Dismissal Litigation
Many wrongful termination lawsuits arise not because employers acted maliciously, but because policies, documentation, or contracts were unclear.
Common causes include:
- Inadequate Notice or Pay in Lieu: Failing to provide enough notice or termination pay is one of the most frequent triggers of litigation. Common law notice can exceed the ESA minimums, especially for long-term, senior, or older employees.
- Poorly Drafted Employment Contracts: Outdated or non-compliant termination clauses often fail in court. If a clause violates ESA minimums or limits rights improperly, it can be struck down entirely, exposing employers to full common law notice obligations.
- Lack of Documentation: Without written records of performance issues or disciplinary measures, employers struggle to justify termination decisions. Courts expect consistent, well-documented management practices.
- Misclassification of Workers: Labelling employees as “independent contractors” or “temporary workers” without meeting legal criteria can lead to back pay, benefits, and wrongful dismissal exposure.
- Insensitive or Retaliatory Conduct: A termination handled poorly, especially one linked to a complaint, leave, or accommodation request, can lead not only to a wrongful dismissal lawsuit but also to human rights or reprisal claims.
💡Tip: Review termination clauses and contracts annually to ensure compliance. Even small errors in wording can render a clause unenforceable in court.
Legal Framework: The ESA and Common Law
Under the Employment Standards Act (ESA), employees are entitled to minimum notice and severance pay based on years of service. However, these are minimums only; courts often award significantly more under common law, unless a valid, enforceable employment contract says otherwise.
Employers should also consider Human Rights Code protections and the duty to accommodate before proceeding with termination. Failing to consider disability, family status, or other protected grounds can turn a routine dismissal into costly litigation.
As Christopher Achkar, employment lawyer and founder of Achkar Law, explains:
“Avoiding wrongful dismissal claims starts with clear contracts, consistent practices, and legally sound termination processes. Before making any termination decision, speak to a lawyer to protect your business from costly legal consequences.”
Wrongful Dismissal Litigation: How It Happens
When a dispute escalates, the process usually follows these steps:
- Demand Letter: The former employee’s lawyer sends a letter alleging wrongful dismissal and requesting compensation.
- Negotiation or Mediation: Many cases settle before court through negotiation or mediation.
- Statement of Claim: If unresolved, the employee files a claim with the Ontario Superior Court of Justice or Small Claims Court (for claims up to $50,000).
- Defence and Discovery: Both sides exchange evidence, including contracts, pay records, and communications.
- Settlement or Trial: The majority of wrongful dismissal cases settle before trial, but preparation is key.
Employers represented by an experienced wrongful dismissal lawyer can often resolve disputes quickly and cost-effectively before litigation escalates.

The Hidden Risks of Outdated Employment Contracts
Common Employer Missteps in Wrongful Dismissal Litigation
Even well-meaning employers can make costly errors after a dispute begins:
- Communicating directly with the dismissed employee after receiving a lawyer’s letter
- Failing to preserve documents and emails
- Offering low, arbitrary settlements
- Ignoring human rights or reprisal aspects of the claim
A seasoned wrongful dismissal defence lawyer can guide employers through the process, manage communications, and negotiate effectively.
What About Wrongful Termination Settlements in Ontario?
Most wrongful dismissal cases in Ontario settle out of court, often through mediation.
The settlement amount depends on:
- Employee’s service length, position, and age
- The validity of their employment contract
- How the termination was handled
- Whether there was bad faith or reputational harm
Employers benefit from early, strategic settlement discussions guided by a wrongful termination law firm that understands both litigation risks and business priorities.
