How Much Does an Employer Pay in MOL Fines for Unpaid Overtime in Ontario?

8 Jun 2026 4 min read No comments Unpaid Wages & Overtime Ontario

Employers in Ontario face strict penalties for unpaid overtime. A standard Notice of Contravention carries administrative fines starting at $250 CAD. However, severe prosecutions under the Employment Standards Act can lead to corporate fines of up to $100,000 CAD for a first conviction and up to $500,000 CAD for repeat offences.

Running a business in Ontario requires careful adherence to the Employment Standards Act, 2000 (ESA). When employers fail to pay proper overtime wages, the Ministry of Labour, Training and Skills Development (MLTSD) has the authority to intervene forcefully . Whether your company is based in Toronto, Hamilton, or London, understanding the severe financial risks of non-compliance is absolutely critical. Failing to compensate employees correctly not only damages your reputation but can also lead to devastating financial penalties that threaten your bottom line.

Types of Financial Penalties for Employers

When the Ministry of Labour investigates a complaint and determines that an employer owes unpaid overtime, they will issue a formal Order to Pay. However, the costs do not stop at just repaying the employee. The provincial government can also issue administrative fines and pursue formal prosecution through the courts.

Notice of Contravention (NOC)

If an Employment Standards Officer finds a violation, they will typically issue a Notice of Contravention. This is a direct administrative penalty for breaking the rules . The fines automatically multiply depending on how many employees were affected by the policy and whether the business is considered a repeat offender.

Prosecution Under the ESA (Part III)

In cases of severe, intentional, or repeated violations, the Ministry of Labour can escalate the matter to a formal prosecution in a provincial offences court. If convicted, the fines are exponentially higher. A corporation can be fined up to $100,000 CAD for a first offence. Furthermore, directors and officers of the corporation can be held personally liable, facing individual fines of up to $50,000 CAD or even up to 12 months in jail for egregious violations.

Step-by-Step Process of an MOL Investigation

Understanding how the Ministry handles these claims can help businesses prepare and respond appropriately 🔍. Ignoring the Ministry of Labour is never a valid defence and will only escalate the fines.

Step 1: The Claim is Filed and Assessed

A current or former employee files a claim regarding unpaid overtime through the Ministry of Labour online portal. The Ministry assesses the claim to ensure it falls under their jurisdiction and assigns an Employment Standards Officer to investigate.

Step 2: Fact-Finding and Document Review

The Officer will contact the employer, legally demanding payroll records, timesheets, and employment contracts . The Ministry may encourage both parties to participate in early resolution or mediation to settle the dispute without issuing formal orders or fines.

Step 3: Issuing the Order and Penalties

If no settlement is reached and the Officer finds the employer at fault, they will issue an Order to Pay Wages. Alongside this, the Officer will issue the Notice of Contravention, requiring the employer to pay the administrative fines directly to the Minister of Finance within a specified timeframe.

What Happens if an Employer Ignores the Order?

Refusing to pay an Order to Pay or a Notice of Contravention is a serious mistake 🚫. The Ministry of Labour does not simply let the matter drop. They will refer the debt to a private collection agency or directly to the Ministry of Finance. The government has broad powers to collect this money, including garnishing the business bank accounts, intercepting funds owed to the business by third parties, or registering a lien against the corporation’s real estate and assets.

How Long Does the Investigation Process Take?

For an employer, an ESA investigation can be a lengthy and stressful distraction ⋯. From the moment a claim is filed by an employee, it generally takes 3 to 6 months for an Officer to reach a decision. If the employer disagrees with the findings and decides to appeal the Order to Pay to the Ontario Labour Relations Board (OLRB), the legal process can drag on for an additional 8 to 12 months, requiring the retention of a corporate law firm.

Frequently Asked Questions (FAQ)

Can directors be held personally liable for unpaid wages?

Yes. Under the Employment Standards Act, corporate directors in Ontario can be held personally liable for up to six months of unpaid wages and up to 12 months of unpaid vacation pay if the corporation itself goes bankrupt or fails to pay.

Is there an administrative fee on top of the Order to Pay?

Yes. If an Order to Pay is issued, the employer must pay the owed wages to the employee, plus an administrative fee to the government equal to 10% of the amount owed, or $100 CAD, whichever is greater.

How can an employer appeal a Notice of Contravention?

Employers have exactly 30 days from the date of the Notice to file a formal appeal with the Ontario Labour Relations Board (OLRB). Crucially, you must typically pay the full penalty amount into trust with the Director of Employment Standards before the appeal will even be processed.

Are salaried employees entitled to overtime in Ontario?

Generally, yes. Being paid an annual salary does not automatically exempt an employee from time-and-a-half overtime pay under the ESA. Only specific, heavily regulated professions (such as managers, lawyers, or certain IT professionals) are strictly exempt from overtime rules.
