Executive Summary: Key Legal and Evidentiary Issues

• Appellants challenged the trial judge's admission of over 300 pages of allegedly late-disclosed documents, claiming procedural unfairness and "trial by ambush."

• Dispute centered on whether the homeowners repudiated a fixed-price construction agreement by taking occupancy on March 11, 2022 without making final payment less deficiency holdbacks.

• Contested mid-trial amendment to the respondent's counterclaim added a $4,077.63 lumber bill, which the appellants argued was already paid and procedurally improper.

• Interpretation of "substantial completion" versus "complete" under the construction agreement and the Builder's Lien Act was pivotal in determining when payment became due.

• Trial judge awarded the respondent $21,155.64 (including interest) after set-off, crediting the appellants only $350 in proven damages against the amended counterclaim.

• On appeal, the Supreme Court of British Columbia found no palpable and overriding error in the trial judge's findings of fact, application of law, or exercise of discretion, and dismissed the appeal.

The construction agreement and the parties involved

On March 9, 2021, Milene Therese Chung and Wayne Chung entered into a construction agreement with Klein Homes Ltd. 0717233 for the building of a new single-family home in Kamloops, British Columbia. The contract price was set at $844,620.00, plus applicable taxes, and was payable by the owners at specified intervals outlined in Schedule "B" of the agreement, including payments due at deposit, foundation, lock up, drywall, and upon a defined "Payment Event." The Builders Lien Holdback Agreement, which formed part of the contract, defined a "Payment Event" as the earliest of: the date of issuance of a temporary occupancy permit, the date of issuance of a final occupancy certificate, or the date the owners moved into or otherwise occupied the home.

Key contractual terms at issue

The agreement contained several provisions central to the dispute. Clause 1 required the contractor to build the home in accordance with the construction specifications (Schedule "A") and building plans supplied by the owners, with the construction specifications governing in cases of discrepancy. Clause 4 addressed pre-occupancy inspections and stipulated that the contractor would rectify noted omissions and defects before the owners moved in. Clause 12 allowed the owners to terminate the agreement if the contractor neglected to perform the work properly, and Clause 13 granted the contractor the option to cease work and treat the agreement as repudiated if the owners defaulted on payment, with outstanding amounts bearing interest at 15% per annum.

The breakdown in the parties' relationship

Toward the end of construction in early 2022, communication between the parties deteriorated as occupancy transfer approached. The Chungs alleged several issues with the quality of workmanship, including the contractor's use of Beauty Tone paint instead of the contractually specified Benjamin Moore, the failure to install interior soundproofing, and damage to owner-supplied items such as a porcelain shower. They further contended that the respondent overcharged for items already included in the agreement by getting Wayne Chung to sign change orders on the understanding that Milene Chung had agreed to the changes. The Chungs attempted to resolve these issues through to May 2022 to no avail, asserting they presented two cheques to the respondent on May 11, 2022 to bring the project to completion, and that the respondent purposely only cashed one of the cheques so as to make it appear that the appellants had not paid in full.

The small claims proceedings

The Chungs filed a notice of claim on November 20, 2023, seeking payment of $26,286.22, plus fees, for items including concrete driveway completion ($12,263.99), interior soundproofing and incorrect paint ($7,800.00), builder-initiated change orders ($2,317.83), plumbing fees ($1,205.00), and quartz shower surround damage/repairs and fireplace mantel ($2,700.00). Klein Homes filed a reply on November 27, 2023, disputing the claims and alleging that the appellants repudiated the agreement on March 11, 2022 by taking possession of the home without making final payment, less deficiency holdbacks. The respondent also filed a counterclaim for $13,431.94 plus filing fees representing the difference (inclusive of interest) between the agreement amount and the amount outstanding. The trial, held over four days in September 2024 and February 2025, resulted in the Provincial Court trial judge finding that the Chungs had failed to meet their payment obligation upon taking occupancy and had thereby repudiated the contract. The trial judge credited the Chungs with only $350 in proven damages, and the set-off between the claim and the amended counterclaim resulted in a judgment against them in the amount of $21,155.64, including interest from March 11, 2022.

The appellants' grounds of appeal

The Chungs appealed to the Supreme Court of British Columbia, raising multiple grounds. They alleged the trial judge erred by admitting and assigning significant weight to late-disclosed documents, by allowing a mid-trial amendment to the counterclaim to include an additional $4,077.63 for lumber, and by relying on terms such as "substantial completion" and "interim occupancy" that were not defined terms in the original agreement. They argued they were not obligated to pay until the home was "complete" or "completely finished" rather than merely "substantially complete," and that the respondent — not themselves — had frustrated the contract by ultimately abandoning the project.

The appeal court's analysis and ruling

Justice L. Bennett of the Supreme Court of British Columbia reviewed the appeal under the palpable and overriding error standard, as established in case law including Reotech Construction Ltd. v Snider, 2022 BCSC 317 and Housen v Nikolaisen, 2002 SCC 33. On the disclosure issue, the Court found that the trial judge acted within his broad statutory discretion under the Small Claims Act and Small Claims Rules, which grant considerable latitude regarding evidence and procedure, and that the appellants wanted to proceed with the trial notwithstanding the disclosure issue and did not ask for an adjournment. On the mid-trial amendment, the Court noted the respondent was not asserting a new cause of action but instead sought to correct the amount owing as a result of a lumber allowance that had not been properly accounted for, and the appellants had the opportunity to respond and to cross-examine a representative of the respondent on this issue. Regarding contract interpretation, the Court rejected the appellants' assertion that the terms of the agreement must be viewed in a vacuum, noting that "substantial completion" and "interim occupancy" are part of a much larger factual and legal lexicon particularly in disputes involving construction contracts, and that the Builder's Lien Act, S.B.C. 1997, c. 45, itself defines "completed" as substantially completed or performed, not necessarily totally completed or performed. The record reflected that the appellants reviewed all relevant documents prior to signing them, signed a job completion certificate in which they agreed the project was "substantially complete," and agreed to take possession as of March 11, 2022, yet on multiple occasions confirmed in writing that the respondent would receive "no money." The appeal was dismissed in its entirety, with the Court concluding there was no material error, serious misapprehension of the evidence, or error in law in the case. The respondent, Klein Homes Ltd., was entitled to costs, but as the respondent was self-represented, the costs were limited to those fees paid to the court registry and to any reasonable photocopying costs. The funds paid into court pursuant to the Provincial Court order of Judicial Justice Adair on January 14, 2026 were ordered to be paid out forthwith to the respondent. The $21,155.64 judgment from the trial level was left undisturbed on appeal.
