How to Legally Fire an Employee for Theft with Just Cause in Ontario

🚨

Firing an employee for theft in Ontario requires undeniable proof to meet the incredibly high threshold for just cause termination. Without a thorough investigation and concrete evidence, your business faces significant risks of a costly wrongful dismissal lawsuit in the Superior Court of Justice.

Discovering that an employee has stolen from your business is a deeply stressful experience. Whether you operate a retail store in Toronto, a manufacturing plant in Mississauga, or a corporate office in Ottawa, employee theft breaks the fundamental bond of trust. However, under Ontario employment law, you cannot simply fire someone on a hunch. The burden of proof rests entirely on the employer to demonstrate that the theft occurred and that the employment relationship is irreparably broken.

In Canada, courts view termination for just cause as the “capital punishment” of employment law. It means the employee is dismissed without notice, without severance pay, and often faces a difficult time securing future employment. Because the consequences are so severe, judges at the Superior Court of Justice demand rigorous, well-documented evidence. Most local law firms strongly advise employers to follow a strict investigative process before making any final decisions. Failing to do so can result in massive financial penalties, including aggravated damages for bad faith behaviour.

Step-by-Step Process for Terminating an Employee for Theft in Ontario

Whether your business is located in Hamilton, London, or anywhere else in the province, the process generally follows these crucial steps to ensure legal compliance and minimize your liability.

Step 1: Suspend the Employee Pending Investigation

When you first suspect theft, do not immediately fire the employee. Instead, place them on an administrative suspension with pay. Suspending an employee without pay can be viewed as a disciplinary action or even a constructive dismissal before the investigation is complete. Let the employee know that an investigation is underway and that they are required to remain available during their regular working hours.

Step 2: Gather Undeniable Evidence

Your investigation must be objective and thorough. Gather all relevant documents, financial records, inventory logs, and surveillance footage. If the theft involves digital assets or funds, preserve the computer logs and bank statements. It is highly recommended to hire an independent investigator or consult with an Ontario employment lawyer to ensure evidence is collected legally, respecting privacy laws. Remember, a simple suspicion or a minor inventory discrepancy is not enough to prove theft in a court of law.

Step 3: Conduct an Investigative Interview

Before finalizing your decision, you must give the employee an opportunity to explain the situation. Invite them to an interview and present the evidence you have gathered. Ask clear, direct questions and take detailed notes of their responses. Sometimes, what appears to be theft might be an administrative error or a misunderstanding of company policy. Giving the employee a chance to defend their behaviour is a critical component of procedural fairness.

Step 4: Decide on Police Involvement

If the evidence clearly points to theft, you must decide whether to report the incident to your local police service (such as the Toronto Police Service or Ottawa Police Service). Keep in mind that a criminal conviction requires proof “beyond a reasonable doubt,” while an employment termination requires proof on a “balance of probabilities.” An employee might not be convicted of an indictable offence or summary conviction in criminal court, but you may still have enough grounds for just cause termination. However, relying solely on a police arrest is not sufficient for dismissal; you must conduct your own workplace investigation.

Step 5: Issue the Termination Letter and ROE

If the investigation confirms the theft and justifies termination, draft a clear termination letter outlining the reasons for dismissal. You must clearly state that the termination is for just cause due to theft. Following the termination, you are legally required by Service Canada to issue a Record of Employment (ROE). While paper ROEs must be issued within 5 calendar days of the termination, electronic filings (such as through ROE Web) are generally due 5 calendar days after the end of the pay period in which the interruption of earnings occurred (or within 15 calendar days for monthly payrolls). On the ROE, you will use Code M for “Dismissal.” Be aware that indicating dismissal for cause will likely disqualify the individual from receiving Employment Insurance (EI) benefits.

How Much Does a Just Cause Termination Cost in Ontario?

While firing an employee for just cause under common law can relieve your business of common law reasonable notice, it does not automatically exempt you from paying statutory termination or severance pay under the Employment Standards Act (ESA). As confirmed by the Court of Appeal in Render v. ThyssenKrupp Elevator (Canada) Limited (2022 ONCA 310), to withhold statutory payments, employers must meet the much higher statutory threshold of “wilful misconduct, disobedience or wilful neglect of duty” (O. Reg. 288/01). This requires proving that the employee’s behavior was deliberate and preplanned—meaning even an accusation of theft may still require statutory payouts if premeditation cannot be proved. If you get it wrong, the financial backlash can be devastating.

  • Investigation Costs: Hiring a private investigator or forensic accountant can cost anywhere from $2,000 to $10,000 CAD, depending on the complexity of the theft.
  • Lawyer Fees: Consulting with an employment law firm in Ontario typically costs between $300 and $600 CAD per hour. Having a lawyer review your evidence before termination is a vital investment.
  • Wrongful Dismissal Liability: If a judge decides you lacked sufficient proof, you could be ordered to pay wrongful dismissal damages. This can range from a few weeks of pay to up to 24 months of full salary, plus potential punitive damages for false accusations of a criminal offence.

How Long Does the Investigation and Legal Process Take?

An internal workplace investigation should be conducted promptly, usually taking between a few days to two weeks. You cannot drag out a paid suspension indefinitely. If the former employee decides to sue you for wrongful dismissal, civil litigation in the Ontario Superior Court of Justice generally takes 12 to 24 months to reach a trial, though most cases settle out of court during mediation.

Frequently Asked Questions (FAQ)

Can I deduct stolen money from their final paycheque?

No. Under the Ontario Employment Standards Act (ESA), you cannot legally deduct alleged stolen funds from an employee’s wages without a court order or their explicit, written consent. Withholding pay illegally can result in severe fines from the Ministry of Labour.

What if the employee only stole something small, like office supplies?

Ontario courts apply the principle of proportionality. Firing a long-term, flawless employee with just cause for stealing a $5 pen is incredibly risky and will likely be deemed a wrongful dismissal. The punishment must fit the severity of the offence.

Do I still have to pay out their accrued vacation pay?

Yes. Even if an employee is fired for just cause, the ESA mandates that all accrued and unpaid vacation pay up to the date of termination must be paid out on their final paycheque.

Should I force the employee to sign a confession?

Never force or coerce an employee into signing a confession. A confession obtained under duress (e.g., “sign this or I’ll call the police”) is generally inadmissible in court and can expose your business to claims of intimidation and bad faith.
