- Court of Appeal for Ontario
- Citation
- 2026 ONCA 577 ↗
- Date
- August 10, 2026
- Area of law
- Employment Law
- Key issue
- Whether a disability that prevents an employee from performing essential duties frustrates an employment contract, and whether personal use of a company tow truck and cellphone constitutes a compensable fringe benefit.
- Outcome
- The Court of Appeal dismissed the frustration argument but reduced the damages award by disallowing compensation for the company tow truck and cellphone, finding they were work tools rather than personal perquisites.
- Why it matters
- Employees facing disability-related terminations need to understand how courts distinguish between a frustrated contract and a wrongful dismissal, and employers must know that company assets used for work are not automatically compensable benefits.
Legal principle
The rule from this case
Frustration of an employment contract on the basis of disability is a high bar to clear. A court will not find frustration simply because an employee cannot perform their job at a given moment. The employer must show there is no reasonable likelihood the employee will return to their essential duties within a reasonable time — and the duty to accommodate up to the point of undue hardship must be considered before that conclusion can be reached. On the question of fringe benefits, an employee who claims compensation for the personal use of a company asset bears the burden of proving both that they were entitled to that use and what it was actually worth. If the asset — such as a vehicle or a phone — was primarily a work tool rather than a personal perk, courts will not treat it as a compensable benefit, even if the employee had some incidental personal use of it.
Important limits
What this does not mean
This decision does not mean that a long-term disability can never frustrate an employment contract. If the medical evidence genuinely shows no reasonable prospect of return, and the employer has exhausted its accommodation obligations, frustration may still be a valid legal conclusion. The ruling simply confirms that employers cannot rely on a temporary or uncertain disability to end the employment relationship without meeting that demanding standard. The ruling also does not mean employees can never recover for the loss of a company vehicle or phone. If an employee can demonstrate that personal use of a company asset was a genuine, agreed-upon benefit — not merely incidental to their job — and can put a real dollar value on that loss, compensation may be available. The outcome here turned on the specific evidence presented, not a blanket rule against such claims.
Can a disability legally end your employment contract in Ontario?
No — at least not automatically. Under Ontario employment law, an employer cannot simply point to a worker’s disability and declare the employment contract “frustrated” without first meeting a demanding legal standard. The Court of Appeal’s decision in Hill v. 1359768 Ontario Inc. (B&B Towing), 2026 ONCA 577 (CanLII), confirms that frustration of contract in the disability context requires much more than showing an employee currently cannot do their job.
What does “frustration of contract” mean in employment law?
Frustration of contract is a legal doctrine that ends an employment agreement when an unforeseen event makes it impossible to perform — through no fault of either party. In the disability context, an employer might argue that a serious illness or injury has made it impossible for the employee to ever return to their essential duties, so the contract is effectively over.
The problem is that this argument is often raised too early or without adequate evidence. Courts require proof that there is no reasonable likelihood of the employee returning to their essential duties within a reasonable time. A temporary inability to work — even a prolonged one — does not automatically meet that standard.
What role does the duty to accommodate play?
Before frustration can be established, the employer’s duty to accommodate must be considered. Ontario’s human rights framework requires employers to adjust working conditions, duties, or schedules to support an employee with a disability — up to the point of undue hardship.
In this case, the court looked at whether the employee’s essential duties as a road boss could be accommodated, and found that prior accommodations had been accepted and that the limitations were temporary in nature. Because the employer had not shown that accommodation would cause undue hardship, frustration could not be made out. Our Ontario employment lawyers regularly advise both employees and employers on where this line falls.
Are company vehicles and cellphones compensable benefits in a wrongful dismissal claim?
Not automatically. While some workplace perks — like car allowances or personal-use vehicles — can form part of a wrongful dismissal damages award, the employee must prove two things: that they were genuinely entitled to personal use of the asset, and what that personal use was actually worth.
The Court of Appeal found that the tow truck and cellphone provided to the employee were work tools, not personal perquisites. There was insufficient evidence that the employee had a personal entitlement to use them outside of work, or that any such use had a measurable dollar value. As a result, the damages award was reduced by removing those items. This is a reminder that not every workplace benefit automatically translates into a compensable loss.
How do courts decide if a company asset is a “perk” or a “work tool”?
Courts look at several factors, including whether the asset appears as a taxable benefit on the employee’s tax records, whether there is evidence of regular personal use, and whether the employment agreement or workplace practice treated personal use as part of the employee’s compensation package.
If the asset was provided purely to do the job — and personal use was incidental or not formally recognized — courts are unlikely to award damages for its loss. Employees who believe a company vehicle or phone was a genuine part of their compensation should gather evidence of that understanding early, ideally in writing.
What should employees do if they are terminated while on disability leave?
Being dismissed while on disability leave raises serious legal concerns, including potential human rights violations and wrongful dismissal. An employer who terminates an employee without first fulfilling the duty to accommodate may face significant liability — regardless of whether they frame the termination as a “frustration” of the contract.
If you are facing termination while dealing with a health condition, it is important to understand your rights before signing anything. Employees in the Hamilton and Burlington area can connect with our Burlington employment law team for guidance specific to their situation.
Practical takeaways for employees facing disability-related termination
- Do not accept “frustration” at face value. An employer claiming your contract is frustrated by disability must meet a high legal standard — temporary inability to work is not enough.
- Document all accommodation requests and responses. If your employer has not genuinely tried to accommodate your disability, frustration cannot legally be established.
- Review your employment agreement and pay stubs. If a company vehicle or phone was treated as a taxable benefit or included in your compensation package, preserve that evidence.
- Get legal advice before signing a release. Severance offers made during or after disability leave may significantly undervalue your entitlements.
- Know the difference between ESA minimums and common law notice. Wrongful dismissal damages can far exceed the statutory minimums — especially after a long period of service.

FAQ
Frequently asked questions
Terminating an employee while they are on disability leave is legally risky for employers. Before ending the employment relationship, the employer must fulfill its duty to accommodate the disability up to the point of undue hardship. Failing to do so can give rise to a wrongful dismissal claim and a human rights complaint.
Frustration of contract means the employment agreement ends automatically due to an unforeseen event — like a permanent inability to work — with no wrongdoing by either party. Wrongful dismissal means the employer ended the contract without proper notice or cause. The distinction matters because frustration, if properly established, can limit the damages an employee can recover.
It can, but the employee must prove they had a genuine entitlement to personal use and establish its monetary value. If the vehicle was primarily a work tool with only incidental personal use, courts are unlikely to include it in a damages award.
