Hamilton Employers’ Guide to Severance and Wrongful Dismissal in Ontario

Date Released
July 30, 2026

Hamilton’s economy is incredibly diverse and evolving rapidly. From the massive industrial sectors and heavy manufacturing in the port lands to the booming healthcare, logistics, and tech startups clustering around McMaster Innovation Park, businesses here are scaling faster than ever. However, with a growing workforce comes the inevitable challenge of managing employee transitions.

Let’s face it: terminating an employee is one of the most stressful and legally dangerous tasks a business owner has to handle. One misstep can lead to a devastating wrongful dismissal lawsuit, costing your company tens of thousands of dollars in legal fees and settlement payouts. For Hamilton Employers, understanding the strict rules of the Ontario Employment Standards Act (ESA) and the complexities of common law is absolutely essential.

At Rozek & Co, we believe that proactive legal strategy is the ultimate defense for your business. Our “Lean Law” model strips away the bloated overhead and unpredictable hourly billing of traditional law firms, providing you with high-level, cost-effective employment law solutions at the speed of modern business.

Here is an educational, conversational guide to navigating severance and wrongful dismissal in Ontario, so you can protect your bottom line.

1. The Basics: Termination Pay vs. Severance Pay

Many employers use the terms “termination pay” and “severance pay” interchangeably, but under Ontario law, they are two completely distinct financial obligations.

Termination Pay (Notice): Under the ESA, if you terminate an employee without cause, you must provide them with advance working notice or pay in lieu of that notice. The statutory minimum scales with tenure and tops out at 8 weeks of pay for employees who have been with your company for eight years or more.

Severance Pay: Severance pay is an additional statutory obligation designed to compensate long-term employees for their loyalty and the loss of their seniority. In Ontario, you are legally required to pay statutory severance if:

  1. The employee has worked for you for at least 5 years, AND
  2. Your company has a global payroll of $2.5 million or more, OR you are conducting a mass termination of 50+ employees within a 6-month period.

If these conditions are met, the employee is entitled to one week of severance pay for every year of service, up to a maximum of 26 weeks—and yes, this must be paid in addition to their termination pay.

2. The Trap of Common Law (Why Wrongful Dismissal Happens)

Here is the biggest legal trap that catches Hamilton Employers off guard: The ESA only dictates the absolute minimum you owe a terminated employee.

If you do not have a meticulously drafted employment contract in place, your employees are automatically entitled to Common Law Reasonable Notice. Unlike the ESA, common law severance is not capped at 8 or 26 weeks. Instead, judges calculate it based on a variety of factors: the employee’s age, length of service, the seniority of their position, and the availability of similar jobs in the Hamilton market.

Under common law, a senior manager or an older, long-term employee could easily be entitled to 12, 18, or even up to 24 months of severance pay.

What actually is a Wrongful Dismissal? Wrongful dismissal rarely means you fired someone for an explicitly illegal reason (like discrimination). Most of the time, “wrongful dismissal” simply means an employer terminated an employee without cause and only offered them the ESA minimums, rather than their full common law entitlement.

3. “Just Cause” is Harder Than You Think

Many employers think they can easily avoid paying severance by firing an underperforming employee “for cause.” In Ontario, this is incredibly difficult to execute.

To legally terminate an employee without owing them a dime of notice or severance under the ESA, you must prove “willful misconduct, disobedience or willful neglect of duty”. This is a very high legal threshold. Chronic lateness, general incompetence, or poor sales performance usually do not qualify. If you attempt a “just cause” termination and fail to prove it in court, you will be on the hook for full common law damages, plus potentially punitive damages for acting in bad faith.

It is almost always safer and more cost-effective to terminate an employee “without cause” and offer a strategic, legally compliant severance package.
