Fired for Breaching Confidentiality Policies in Ontario

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

Being fired “for cause” due to a confidentiality breach in Ontario is legally difficult for employers to justify. Unless you committed severe, willful misconduct (like selling trade secrets to a competitor), you may still be entitled to full severance pay. Filing a wrongful dismissal lawsuit at the Superior Court of Justice currently requires a basic filing fee of $339 CAD.

In today’s digital age, sharing information is easier than ever, but it also increases the risk of accidentally violating your employer’s confidentiality rules. 📍 In Ontario, most employment contracts include strict Non-Disclosure Agreements (NDAs) or confidentiality clauses designed to protect client data, trade secrets, and internal company matters. When an employee breaches these policies, employers often react aggressively by terminating them immediately “for cause,” claiming they no longer owe the employee any severance.

However, Ontario employment law draws a sharp line between a minor lapse in judgement and intentional sabotage. Simply venting to a spouse or accidentally copying the wrong person on an email usually does not meet the incredibly high threshold for a “just cause” termination. To completely deny your severance, the employer must prove your behaviour amounted to willful misconduct, disobedience, or deliberate neglect of duty under the Employment Standards Act (ESA).

Step-by-Step Process in Ontario

Whether you were working for a tech startup in Toronto, a government contractor in Ottawa, or a manufacturing firm in Mississauga, responding to a termination over confidentiality requires a careful, strategic approach. 📚 Here are the steps you should follow if you find yourself in this situation.

Step 1: Do Not Sign Anything Immediately

When you are fired, your employer may present you with a termination letter and demand that you sign a release to receive a small, inadequate severance offer. Never sign on the spot. In Ontario, you are completely entitled to take the paperwork home and have a law firm review it. Signing a release permanently legally bars you from seeking further compensation.

Step 2: Review Your Original Employment Contract

You must locate the employment contract you signed when you were hired. 🔍 Look specifically for clauses relating to confidentiality, proprietary information, and NDAs. Understanding exactly what you agreed to is crucial. If the confidentiality policy was never clearly communicated to you, or if it is overly broad, your lawyer may be able to argue that the policy is legally unenforceable.

Step 3: Analyze the Nature of the Breach

Ontario courts look closely at the context of the breach. Did you deliberately steal client lists to start your own competing business, or did you accidentally leave a sensitive document on a shared printer? If the breach was an honest mistake and you did not financially benefit from it, your employer will have a very difficult time justifying a termination without severance.

Step 4: Secure Your Personal Evidence

Before you are locked out of the company systems, try to preserve any evidence showing your good performance and the context of the incident (do not take any more confidential data). 💻 Once you are locked out, write down a detailed, chronological account of the events from your memory. Note down any witnesses, previous warnings (or lack thereof), and how management handled similar mistakes made by other employees in the past.

Step 5: Apply for Employment Insurance (EI)

Even if your employer claims you were fired for cause, you should still immediately apply for Employment Insurance (EI) through Service Canada. If Service Canada denies your application based on your employer’s Record of Employment (ROE), you have the right to appeal the decision and explain that the breach was not willful misconduct.

Step 6: Consult an Employment Lawyer

You must hire an Ontario employment lawyer to evaluate your case. ⚠️ A legal professional will assess whether the employer’s actions hold up under common law. If the employer’s claim of “just cause” is weak, your lawyer will draft a formal demand letter outlining your legal entitlements and requesting proper severance pay.

Step 7: Filing a Claim at the Superior Court of Justice

If your employer refuses to negotiate a fair settlement, your lawyer will issue a Statement of Claim at your local Superior Court of Justice. The vast majority of these disputes are settled out of court through mediation long before a trial takes place.

How Much Does it Cost in Ontario?

Pursuing a wrongful dismissal claim involves specific legal and administrative costs:

  • Court Filing Fees: Issuing a formal Statement of Claim at the Superior Court of Justice across Ontario costs $339 CAD.
  • Law Firm Fees: Most Ontario employment lawyers operate on a contingency fee basis for wrongful dismissal, typically taking between 25% and 35% of the final settlement. Alternatively, hourly rates usually range from $300 to $650 CAD.
  • Mediation Costs: Hiring a private mediator to help settle the dispute out of court normally costs between $1,500 and $3,500 CAD for a half-day, split evenly with your employer.

How Long Does the Process Take?

Under the Ontario Limitations Act, you generally have a strict 2-year window from the date of your termination to file a civil lawsuit. ⌛

  • Demand Letter & Negotiation: The initial phase of sending a demand letter and negotiating with the employer’s legal counsel takes about 1 to 3 months.
  • Litigation Phase: If a lawsuit must be filed, progressing through discoveries and mandatory mediation at the Superior Court typically takes 12 to 24 months.
  • EI Appeals: If you need to appeal a Service Canada EI denial, that administrative process usually takes 1 to 3 months.

Frequently Asked Questions (FAQ)

Can I be fired for sharing my salary information with a coworker?

Generally, no. Ontario employers cannot legally penalize you for discussing your wages with coworkers. The Employment Standards Act protects employees who ask about or share their rate of pay to ensure equal pay for equal work.

What happens if I accidentally send a confidential email to the wrong person?

An honest mistake is rarely considered “willful misconduct.” While your employer can still fire you without a specific reason, they are generally required to provide you with a full severance package unless they can prove deliberate malice or gross incompetence.

Do I have to return my company laptop if they fired me?

Yes. Even if you believe you were wrongfully dismissed, you must immediately return all company property, including laptops, keys, and documents. Keeping company property can lead to civil lawsuits against you and severely damage your wrongful dismissal claim.

Will this termination show up on my criminal record?

No, a workplace confidentiality breach is generally a civil contract dispute, not a criminal matter. Unless you stole data to commit an indictable offence like fraud and the police charge you, it will not affect your criminal record.
