Wrongful dismissal claims cost Ontario employers tens of thousands in legal fees and settlement costs. The good news? Most claims are preventable with proper planning and documentation.
Here’s how to protect your business from unfair dismissal lawsuits.
Start with Strong Employment Contracts
The foundation of dismissal protection is a well-drafted employment contract with a valid termination clause. Without one, you’re stuck paying common law severance—often 12-24 months for long-service employees instead of reasonable contractual limits.
Your contracts should clearly define termination notice periods, limit severance to reasonable amounts above ESA minimums, include probationary period terms, and specify job duties and reporting structure. Have a lawyer draft or review contracts before employees sign them. Courts regularly strike down DIY template contracts, leaving you with full common law liability.
Document Performance Issues Properly
Poor documentation is the biggest reason employers lose wrongful dismissal cases. When terminating for performance reasons, you need clear evidence showing the employee knew about problems and had opportunities to improve.
Create a paper trail by providing written performance reviews, documenting specific incidents with dates and details, issuing formal warnings for serious issues, and keeping records of improvement plans and outcomes. Verbal warnings alone won’t protect you. If you can’t prove performance problems in writing, don’t claim them as justification for termination.
Use Progressive Discipline Consistently
Courts expect employers to follow progressive discipline before terminating for performance issues. This typically means verbal warning for first offense, written warning for repeated issues, final written warning stating termination is next, and termination only after employee fails to improve.
Skip steps for serious misconduct like theft or violence, but for performance or minor policy violations, follow your discipline policy consistently. Firing someone for an issue you’ve ignored in other employees undermines your case.
Calculate Severance Correctly
Offering inadequate severance guarantees a wrongful dismissal claim. Many employers mistakenly offer only Employment Standards Act minimums (maximum 8 weeks) when employees are entitled to months of common law notice.
Unless you have a valid contract limiting severance, calculate reasonable notice based on the employee’s age, length of service, position, and job market conditions. A 50-year-old manager with 10 years of service typically deserves 12-15 months, not 8 weeks. Getting this calculation right from the start often prevents litigation entirely.
Avoid These Common Mistakes
Never attempt “just cause” termination without rock-solid evidence. Just cause means firing without severance for serious misconduct like theft, fraud, or violence. Poor performance doesn’t qualify. If you claim cause but can’t prove it, courts award enhanced damages on top of severance.
Don’t terminate employees during or shortly after protected leaves like medical leave, pregnancy leave, or following discrimination complaints. The timing creates a presumption of illegal conduct that’s difficult to overcome. If you must terminate someone on leave, get legal advice first.
Never provide inconsistent reasons for termination. If your termination letter says “restructuring” but you later claim “poor performance,” employees will use the contradiction against you. Stick to one clear, documented reason.
Conduct Professional Termination Meetings
How you handle the termination meeting affects whether employees sue. Keep meetings brief and professional, provide written notice with clear severance terms, avoid debating or justifying the decision, and collect company property immediately.
Don’t apologize excessively or suggest the employee did anything wrong unless you’re genuinely terminating for documented cause. Mixed messages create confusion and litigation risk.
Offer Reasonable Severance Packages
Include proper termination pay or notice period, severance pay if ESA requires it, continuation of benefits during notice, accrued vacation pay, and outstanding bonuses or commissions earned. Also provide a clear, written release agreement and reasonable time to review the offer with a lawyer.
Employees who receive fair offers rarely sue. Those who feel cheated almost always consult lawyers and pursue claims.
When to Get Legal Advice
Consult an employment lawyer before terminating employees with 5+ years of service, senior management or executives, anyone considering just cause termination, employees on or recently returned from protected leave, or situations involving recent discrimination complaints.
The cost of a lawyer reviewing your termination plan is far less than defending a wrongful dismissal lawsuit. Proactive legal advice helps you offer appropriate severance, draft proper termination letters, and avoid costly mistakes.
The Bottom Line
Avoiding unfair dismissal claims requires strong employment contracts with valid termination clauses, proper documentation of performance issues, progressive discipline applied consistently, accurate severance calculations, professional termination processes, and legal advice for high-risk situations.
Most wrongful dismissal claims stem from inadequate severance offers or poorly handled terminations. Invest in proper contracts, documentation, and legal guidance upfront—it’s far cheaper than litigation.
