Appeal Fixes a Legal Error, Doesn't Erase the Whole Bill

The situation

Oksana, an administrative assistant, and her partner Bohdan, a factory technician, hired a contractor to renovate the main floor of their Lindsay home. The contractor, Fernanda, ran her own small renovation business and had been recommended by a neighbour. The job went ahead in stages over several months, with payments released as work was completed, the usual pattern for a residential renovation contract.

Partway through, Oksana and Bohdan started noticing problems: uneven flooring, a load-bearing wall opening that did not match the plan, cabinetry installed slightly out of level. They raised the issues with Fernanda, who disputed that the work was deficient and eventually stopped attending the site when the couple withheld a portion of an invoice pending repairs. Fernanda sued for the unpaid balance, which came to roughly $76,000 once she added claimed extras and delay costs. Oksana and Bohdan wanted to counterclaim for the cost of fixing the deficiencies, which a second contractor had quoted at around $22,000.

What the trial got wrong

The case went to trial in the Superior Court under the simplified procedure used for civil claims in this range. It is well established in Ontario construction and contract law that when an owner alleges deficient work, the cost of fixing genuine deficiencies can generally be set off against the amount otherwise owing to the contractor, argued as a defence and counterclaim within the same lawsuit rather than a separate proceeding.

At trial, the judge awarded Fernanda the full amount she claimed. In the written reasons, the judge treated the couple's deficiency evidence as a separate dispute that would need its own lawsuit, rather than as a set-off against the amount owing in the same proceeding. That was the legal error: the trial judge's reasons did not engage with the set-off argument at all, even though it was squarely raised. The couple was left with a judgment for the full $76,000, plus costs, with no credit for the $22,000 in repair work they still needed to pay someone else to do. Oksana and Bohdan had come away from the trial believing the judge simply preferred Fernanda's version of events, and for weeks they assumed there was nothing left to do but pay. It was only once the written reasons were read closely, line by line, that the gap became visible: the deficiency evidence was acknowledged in the decision but never actually weighed against what Fernanda was owed.

An error like this, a judge misapplying or failing to apply the correct legal test, is different from a judge simply weighing evidence and believing one witness over another. Trial decisions get considerable deference on findings of fact. But when a judge applies the wrong legal framework, or ignores a framework that should have governed the analysis, that is a question of law, and questions of law are reviewed by an appellate court without the same deference. This distinction mattered enormously for what came next.

What we did

1. Reviewed the trial reasons specifically for errors of law, not just disappointing outcomes. An appeal is not a second chance to re-argue who was more credible. Our team went through the written decision looking for places where the judge either misstated the applicable law or failed to apply a framework that should have controlled the result. The holdback and set-off omission stood out as a genuine legal error, not a disagreement with how the judge weighed the evidence.
2. Filed the appeal within the strict deadline. Civil appeals in Ontario are governed by short, unforgiving timelines that start running from the date of the judgment, not from when a client decides to act. We confirmed the deadline immediately and filed the notice of appeal well within it, preserving the right to be heard at all.
3. Built the appeal around the narrow legal question. Appellate courts respond best to a focused argument. Rather than re-litigating every factual dispute from the trial, we framed the appeal around one clear proposition: the deficiency set-off was a defence properly raised within this action, the trial judge did not consider it, and that omission was an error of law reviewable without deference.
4. Prepared Oksana and Bohdan for a mitigated outcome, not a clean win. We were candid from the outset that even a successful appeal would likely mean a reduced judgment and a further hearing, not a finding that they owed nothing. Fernanda had performed real work and was owed something; the legal error was about failing to credit the deficiencies, not about the underlying debt being invalid.
5. Negotiated with Fernanda's lawyer once the appeal succeeded. With the legal error confirmed and the file headed back for a further determination of the set-off amount, both sides had an incentive to settle rather than fund another hearing. We used the appellate ruling as leverage to reach a number reflecting the deficiency credit, instead of forcing a second trial on damages alone.

The outcome

The appeal succeeded. The appeal court agreed that the trial judge had erred in law by failing to consider the couple's set-off claim within the same proceeding, and sent the question of the deficiency credit back for a further determination. Facing another hearing, both sides negotiated instead. Oksana and Bohdan ended up paying Fernanda roughly $48,000, down from the original $76,000 judgment, reflecting the $22,000 repair credit plus a modest reduction for the delay and disruption the deficiencies had caused.

That is a real result, and a genuinely better one than standing by a $76,000 judgment with no credit at all. But it was not a win in the sense of owing nothing. Oksana and Bohdan still paid a substantial sum, still faced the cost of the appeal itself, and still had to find roughly $22,000 elsewhere to actually fix the flooring, the wall opening, and the cabinetry, since the credit offset what they owed Fernanda rather than putting cash in their hands for repairs. The legal error was real and worth fighting, but fighting it contained a loss, it did not erase one. That distinction matters for anyone weighing whether an appeal is worth pursuing: it corrects the law, not the underlying facts of a contract that still cost more to finish than expected. For Oksana and Bohdan, the appeal was still worth bringing. A $76,000 judgment with no credit at all would have meant financing a debt that ignored real, documented deficiencies, while a $48,000 negotiated result at least reflected the repair costs they were always going to have to cover somewhere. They finished the flooring and cabinetry work themselves over the following year, paying for it out of savings rather than through the judgment, which was the outcome the appeal made possible rather than one it delivered directly.
