Fired for Insubordination or Refusing a Task in Ontario Workplaces

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

In Ontario, a single act of insubordination rarely gives an employer “just cause” to fire you without severance pay. Unless your refusal to work was intentional, repeated, and fundamentally destroyed the employment relationship, you are likely a victim of wrongful dismissal. If you need to file a claim for your common law severance, the basic filing fee at the Ontario Superior Court of Justice is roughly $229 CAD.

Being terminated from your job for “insubordination” can feel like a massive blow to your professional reputation. Employers frequently use this term when a worker pushes back against an unfair request, questions a new policy, or simply has a disagreement with management. 😕 However, under Ontario law, the bar for proving insubordination is incredibly high. The law generally protects employees from being stripped of their financial safety net over a minor conflict.

Employment law in Ontario requires employers to use progressive discipline-such as verbal and written warnings-before resorting to the ultimate penalty of a “just cause” dismissal. Whether you work in a corporate office in Toronto, a warehouse in Mississauga, or a retail store in Hamilton, your employer cannot legally withhold your severance pay unless your refusal to follow orders was severe enough to make continuing the employment relationship impossible.

Step-by-Step Process in Ontario if Fired for Insubordination

If you were handed a termination letter claiming you were fired for cause due to insubordination, you must act quickly to protect your legal rights. 📋 Follow these crucial steps to challenge the dismissal and secure the pay in lieu of notice you are likely owed.

Step 1: Assess the Nature of the Order You Refused

The first step is evaluating whether the task you refused was actually reasonable and lawful. In Ontario, you have a strict legal right to refuse unsafe work under the Occupational Health and Safety Act (OHSA). If you refused a task because it was dangerous, illegal, or completely outside your job description, the employer’s claim of insubordination will likely fail entirely.

Step 2: Document the Incident and Progressive Discipline

Write down everything you remember about the incident that led to your dismissal. 📝 Ontario courts will heavily scrutinize whether the employer warned you that your behaviour could result in termination. Did they give you a chance to correct your actions? If there is no documented history of warnings in your HR file, judges at the Superior Court of Justice generally view a sudden dismissal as a wrongful dismissal.

Step 3: Do Not Sign a Release Under Pressure

Often, HR will offer you a tiny fraction of your rightful severance in exchange for signing a full and final release, threatening that you will get nothing because of your “insubordination.” Never sign these documents on the spot. You always have the right to take the severance package home and have it reviewed by a local employment law firm.

Step 4: Have a Lawyer Send a Formal Demand Letter

Most insubordination disputes are resolved long before seeing the inside of a courtroom. ✉️ Your employment lawyer will draft a demand letter outlining why your actions did not meet the legal threshold for just cause. This letter will demand proper common law severance pay, which can range from a few weeks to up to 24 months, depending on your age, tenure, and role.

Step 5: File a Claim in Civil Court

If the company refuses to offer a fair settlement, your lawyer will issue a Statement of Claim. For severance packages valued under $35,000 CAD, the process takes place in the Ontario Small Claims Court. For larger corporate severance packages, your case will proceed in the standard Superior Court of Justice, where formal mediation and discoveries occur.

How Much Does it Cost in Ontario?

Challenging a just cause dismissal might seem expensive, but the system is designed to be accessible for wrongfully terminated workers. 💵 Here is an overview of the typical legal and court costs in Ontario as of May 2026:

  • Lawyer Contingency Fees: Most Ontario employment lawyers will represent you on a contingency basis. You pay no hourly rates; instead, the lawyer takes 25% to 33% of your final settlement.
  • Consultation Fees: If you simply need a lawyer to review your termination letter, expect to pay a flat fee of $300 to $500 CAD.
  • Small Claims Court Filing: Issuing a Plaintiff’s Claim for amounts under $35,000 CAD costs approximately $108 CAD.
  • Superior Court Filing: For claims exceeding $35,000 CAD, issuing a Statement of Claim is about $229 CAD.

How Long Does the Process Take?

The timeline to secure your severance after an insubordination firing depends largely on your former employer’s willingness to negotiate.

  • Initial Demand & Negotiation: Drafting the letter and completing the first round of negotiations typically takes 3 to 6 weeks.
  • Ministry of Labour Route: Filing a claim for minimum Employment Standards Act (ESA) severance through the Ministry can take 6 to 12 months due to provincial backlogs.
  • Civil Litigation: If you must sue in Small Claims Court, a mandatory settlement conference happens in about 6 months. A full trial at the Superior Court of Justice can take 1.5 to 2 years.

Frequently Asked Questions (FAQ)

What exactly is considered insubordination in Ontario?

Insubordination is legally defined as an intentional and clear refusal to carry out a lawful and reasonable instruction given by someone in authority. A simple misunderstanding or a polite disagreement over how to do a task is not insubordination.

Can I be fired for refusing overtime?

Under the Ontario Employment Standards Act, you have the right to refuse work beyond your regular daily hours or the 48-hour weekly maximum unless you signed a specific overtime agreement. Firing you for legally refusing overtime is a wrongful dismissal.

Does a written warning mean I lose my severance?

Not necessarily. While a written warning strengthens the employer’s case, Ontario courts require the punishment to fit the offence. If you had one warning for a minor issue and were fired six months later, you are likely still entitled to your full severance pay.

Can I claim Employment Insurance (EI) if fired for insubordination?

Service Canada may initially deny your EI application if your employer issues a Record of Employment (ROE) stating you were fired for “misconduct.” However, you can appeal this decision, and a lawyer can often force the employer to amend your ROE code during settlement negotiations.
