As professional bookkeepers, we’re used to handling complex numbers, balancing ledgers, and keeping businesses financially healthy. While we might feel right at home with tax codes, payroll calculations, and financial statements, employment law is often less familiar territory. And here’s the truth: being the boss doesn’t mean unlimited authority. Ontario’s employment laws are designed to protect workers and breaking them (whether intentionally or accidentally) can cost you dearly in legal fees, penalties, and even your reputation.
If you’re thinking of hiring your first employee or managing a small team, understanding the “no-go zones” of employment law is just as important as filing an accurate tax return. Let’s walk through 11 key things you cannot do as an employer in Ontario, and how to keep your practice compliant and protected.
1. Discriminate in the Workplace
In Ontario, discrimination is strictly prohibited under the Human Rights Code. That means you can’t treat employees differently based on age, gender, race, religion, disability, sexual orientation, or other protected grounds.
This rule applies at every stage—from job postings and interviews to day-to-day management and even termination. Using phrases like “cultural fit” as a hiring filter may seem harmless, but if it’s masking bias, it can lead to serious consequences.
2. Allow Harassment
Respect isn’t optional, it’s the law. Employers must provide a safe and harassment-free environment. Harassment can include inappropriate jokes, unwelcome comments, bullying, or public humiliation.
3. Retaliate Against Employees
If an employee raises a concern, whether it’s about harassment, pay, or workplace safety, you cannot punish them for speaking up. Even if an investigation shows the complaint wasn’t valid, retaliation—like demotion, cutting hours, or firing—can expose you to legal action.
4. Wrongful Termination
This is one of the most common pitfalls for small business owners. You cannot terminate an employee without proper notice or severance pay. Depending on their length of service and circumstances, the cost of a wrongful dismissal can climb to as high as two years’ worth of compensation.
5. Deduct Wages Without Consent
Employers cannot simply dock wages for broken equipment, missing supplies, or mistakes. In Ontario, deductions are only permitted for taxes, statutory benefits, and court-ordered payments. Anything else requires written consent and agreement.
6. Withhold Wages
Even if you’re in the middle of a dispute with an employee, wages for hours worked must still be paid on time. Your cash flow challenges or disagreements don’t override their legal right to prompt payment.
Late or withheld wages not only put you in violation of the law—they also erode trust in your workplace.
7. Deny Vacation Time
Every employee in Ontario is entitled to at least two weeks of vacation per year (after one year of employment), plus 4% vacation pay. For longer-serving employees, this entitlement increases.
8. Force Unpaid Overtime
Here’s a common misunderstanding: salary does not equal exemption from overtime. In Ontario, non-management employees are entitled to time-and-a-half pay for hours worked over 44 per week—regardless of whether they’re paid hourly or salaried.
9. Misclassify Employees as Contractors
Labelling someone a contractor doesn’t automatically make them one. The law looks at the actual working relationship — things like control over hours, equipment used, and independence.
Misclassification is a serious issue that can result in fines, back pay for benefits, and payroll tax liabilities. When in doubt, seek advice before deciding how to structure the working arrangement.
10. Force Retirement or Resignation
In Ontario, the decision to retire is up to the employee. Employers cannot pressure, hint, or coerce an older employee to resign or retire. Doing so can trigger claims of constructive dismissal and age discrimination.
11. Make Unilateral Contract Changes
You cannot unilaterally change key terms of employment—like pay, working hours, or job responsibilities—without the employee’s consent. Major changes without agreement may be considered constructive dismissal, even if you think the change is for the better.
A well-drafted employment contract and clear communication upfront can help prevent these disputes down the road.
The Real Cost of Non-Compliance
Violating employment law isn’t just about paying fines or severance, it’s about protecting the reputation you’ve worked hard to build. A lawsuit or Ministry of Labour investigation can damage client trust, disrupt operations, and create long-term reputational harm.
The financial costs can include:
Severance or back pay / Legal fees / Government fines / Damages awarded by courts
But the intangible costs—like losing the confidence of your team and clients—can be even more damaging.
Protecting Your Business
The good news? With some proactive steps, you can protect yourself and your business. Here are five key strategies:
Work with an employment lawyer before hiring your first employee.
Develop clear contracts and policies to set expectations from day one.
Document everything—from performance reviews to accommodations.
Maintain professionalism with employees, just as you do with clients.
Seek legal advice before making major employment decisions.
Final Thoughts
Running a business is already complex — you don’t need the added stress of employment law violations. Staying compliant isn’t about giving up control; it’s about protecting the business you’ve poured your heart into.
The risks of ignoring workplace laws are simply too high, while the rewards of compliance include a stronger team, better client trust, and a thriving business.
Remember: knowledge is your best defense. By understanding what you can and cannot do as an employer in Ontario, you’re not just following the law, you’re building a healthier, more sustainable business.
