Ontario Court Clarifies Frustration Standard for Disability Leave, Fringe Benefits

A man who had spent seventeen years as a road boss at B&B Towing faced a choice when he returned from two and a half years of disability leave: accept a demotion to tow truck driver at lower pay, or walk away. He walked away, claiming constructive dismissal. The company fought back with a different argument—that his disability had made the job impossible, that the contract itself was frustrated, and therefore they owed him nothing. Ontario's Court of Appeal sided with the employee, and in doing so, clarified what employers actually have to prove when they claim disability has ended a job.

The case turned on a straightforward question: Can an employer simply eliminate a position while an employee is on disability leave, then argue the employee can no longer do the work they used to do? The answer, the court found, is no—not without meeting a high bar. In September 2021, when Mr. Hill met with B&B Towing's owners to discuss his return, they told him the road boss position no longer existed for financial reasons. They offered him eight weeks at his old pay rate, then a permanent move to driving a tow truck at reduced wages. He rejected the offer and sued.

The company's defense rested on the doctrine of frustration—the legal principle that an employment contract can become impossible to perform through no fault of either party. In the disability context, this doctrine exists for real situations: when an employee's condition is so severe and permanent that they genuinely cannot do the work, and no accommodation could reasonably help. But the court emphasized that frustration is not a tool for convenience. An employer must prove three things: that the employee cannot perform the essential duties of the position, that this inability will persist for a reasonable time, and that accommodating the employee would cause undue hardship. The company had not done this.

The trial judge had already rejected the frustration argument, and the Court of Appeal upheld that decision. The evidence showed that Mr. Hill's physical limitations were not permanent. Medical records indicated he could gradually transition back to work. The company had accommodated his restrictions before and could do so again. The physical demands of a road boss and a tow truck driver were similar enough that the same accommodations would likely work for both roles. Most critically, the company had never actually tried to accommodate him or shown that doing so would be impossible. They had simply decided the position was no longer needed and offered him a demotion instead.

But the court also trimmed the damages award in one significant way. The trial judge had awarded Mr. Hill compensation for the loss of a company tow truck and cell phone, treating them as part of his employment benefits package. The Court of Appeal disagreed. A tow truck, the judges reasoned, is a work tool—specialized, heavy-duty equipment provided to do the job, much like a school bus or farm tractor. The fact that Mr. Hill occasionally used it to commute or run errands during lunch breaks did not transform it into a personal benefit. The same logic applied to the cell phone: it was provided for business purposes, not as part of his compensation. Tax records had never treated either item as a taxable employment benefit. The court reduced the damages award from $263,163.77 to $137,523.77 by removing these amounts.

For employers, the decision sends two clear messages. First, frustration is a high hurdle. You cannot simply wait out a disability leave, eliminate a position, and then claim the employee is no longer capable of working. You must engage in genuine accommodation analysis, document your efforts, and show that further accommodation would cause real hardship. Second, be precise about what you provide to employees and why. A vehicle or phone given for work purposes should be clearly documented as such. If it is meant to be part of compensation, say so explicitly in employment agreements and tax filings. Ambiguity invites litigation. The company in this case lost not because it provided tools to an employee, but because it had never clearly defined what those tools were for, leaving a court to guess at the parties' intent.
