Appeals Court Upholds Dismissal of Wrongful Dismissal Settlement Challenge
On September 8, 2025, the Ontario Court of Appeal dismissed an appeal by a former employee who sought to set aside a $500,000 wrongful dismissal settlement with her former employer, Cambridge Mercantile Corp.
The case, Gayle v. Cambridge Mercantile Corp., highlights how courts approach settlement challenges, claims of lawyer negligence, and allegations that an employee was pushed into an unfair agreement.
This article shows how Ontario courts treat settlement challenges and allegations of lawyer negligence. For employers, it reinforces the importance of clear documentation and finality in employment disputes.
The Case at a Glance: What Happened?
Sharna Gayle sued Cambridge Mercantile for wrongful dismissal, claiming she was not properly compensated for working on Jewish holidays under a special agreement. Cambridge counterclaimed for alleged overpayments and defamation by Ms. Gayle’s spouse.
The parties attended mediation and settled. Ms. Gayle accepted $500,000 and signed a full and final release.
More than a year later, she launched a new lawsuit against her former lawyers, alleging they conspired with Cambridge, misled her, and pressured her into an “improvident” settlement. She argued she should have been entitled to millions in profits generated on Jewish holidays.
A Superior Court judge dismissed her claim on summary judgment, finding there was no genuine issue for trial. Ms. Gayle appealed.
As Christopher Achkar, employment lawyer and founder of Achkar Law, explains:
“Settlements bring finality, but only when they’re drafted and executed with care. Employers should always seek legal guidance before finalizing a dismissal settlement to ensure their agreements are enforceable and shield them from future disputes.”
What the Ontario Court of Appeal Decided
The Court of Appeal agreed with the motion judge and dismissed the appeal.
Key Findings
1. Settlement Was Not Improvident
- The Court found that the $500,000 settlement was reasonable given the risks. Cambridge had counterclaims worth hundreds of thousands of dollars, possible statute-barred issues, and strong defences.
2. No Evidence of Lawyer Misconduct
The Court rejected allegations that Ms. Gayle’s lawyers colluded with Cambridge or gave negligent advice. The record showed her counsel provided sound, risk-based guidance.
3. Expert Evidence Was Required But Missing
- While lawyer negligence cases often require expert evidence on the standard of care, Ms. Gayle provided none. Without supporting evidence, her claim could not proceed.
4. Jewish Law Arguments Were Irrelevant
- The Court clarified that employment agreements are interpreted under Ontario law, not religious law. The employee’s argument that profits from Jewish holidays should legally belong to her had no legal basis.
In the end, the Court upheld the dismissal of Ms. Gayle’s lawsuit and ordered her to pay $5,000 in costs.
Why This Case Matters for Ontario Employers
Even though the dispute here centered on a settlement and the employee’s lawyers, there are important takeaways for employers:
- Settlement Agreements Provide Finality
A well-documented settlement and mutual release remain strong protections against future claims. Employers should ensure settlement terms are clear, fair, and properly executed. - Counterclaims Can Strengthen Employer Position
Cambridge’s counterclaims created leverage in settlement negotiations, reducing overall exposure. Employers should consider whether legitimate counterclaims exist when defending against employee lawsuits. - Documentation Is Key
The Court relied heavily on the fact that Ms. Gayle reviewed, approved, and signed the settlement. Employers should keep thorough records of negotiations and agreements. - Litigation Risks Are Real
The decision illustrates how costly, complex, and unpredictable wrongful dismissal litigation can be for employees and employers alike. Proactive risk management and strong contracts reduce exposure.
