• Issues arose over whether the expert, Mr. Bennett, had the necessary expertise with the specific materials involved in the case.

• The trial decision was set aside due to errors in handling expert testimony and a new trial was ordered.

• No costs were awarded as the respondent did not oppose the appeal or cause the proceeding.

Facts of the case

Canadian Choice Home Services Inc. appealed a Small Claims Court decision in favor of Jessie Sibeon. The dispute centered on the admissibility and reliability of expert evidence presented at trial. The expert, Mr. Steve Bennett, provided a report concerning insulation work performed by the defendant. During cross-examination, Mr. Bennett admitted he did not write the entire report himself and lacked expertise with the type of insulation installed by the defendant. The report also included photos not taken by Mr. Bennett and findings that were undermined by his own actions in the attic.

Issues with expert evidence and court procedure

The main legal issue was whether the trial judge erred in law by relying on a cause of action not pleaded, misapprehending material evidence, and failing to properly assess the admissibility and reliability of the expert report. The court highlighted that Rule 33.06 of the Rules of Civil Procedure requires expert reports to be authored solely by the expert. The trial judge accepted Mr. Bennett’s qualifications but did not allow further questioning to clarify which parts of the report were not authored by him or to identify the other contributor. The judge also failed to consider Mr. Bennett’s lack of expertise with fibreglass insulation and his own actions that affected the evidence.

Relevant policy terms and legal framework

The decision referenced Rule 33.06 of the Rules of Civil Procedure, which governs the preparation and authorship of expert reports. The court also cited the Supreme Court of Canada’s guidance in White Burgess Langille Inman v. Abbott and Haliburton Co., emphasizing the ongoing gatekeeping role of judges in assessing expert evidence for relevance, necessity, reliability, and absence of bias.

Outcome and disposition

Justice Bellows found that the trial judge’s failure to exercise the gatekeeping function regarding the expert evidence constituted a palpable and overriding error. The appeal was allowed, the judgment was set aside, and a new trial was ordered. No costs were awarded, as the respondent did not oppose the appeal and was not the cause of the proceeding. Canadian Choice Home Services Inc. was the successful party in this appeal, and no monetary award or damages were ordered as a result of this decision.
