Executive Summary: Key Legal and Evidentiary Issues

• Peter Varadi appealed a Cour du Québec judgment that partially rejected his challenge to tax assessments issued by the Agence du revenu du Québec for the years 2014 to 2017.
• At issue was whether the ARQ was permitted to assess beyond the normal three-year period under paragraph 1010(2)(b)(i) of the Loi sur les impôts for the 2014 tax year.
• Disputed was the standard of proof required of the appellant to "demolish" the presumption of validity underlying the assessments.
• Admissibility of evidence referencing adjustments arising from a Canada Revenue Agency audit conducted jointly with the ARQ was also contested.
• Varadi failed to produce any supporting documents and his testimony was found to lack credibility, undermining his challenge to the assessments.
• Accountant M. Leduc's testimony was found to be clearly insufficient, as his explanations rested solely on hearsay.

Facts of the case

Peter Varadi appealed a judgment rendered on May 6, 2025, by the Honourable Julie Philippe of the Cour du Québec, district of Montréal. The appeal was heard on June 11, 2026, before a panel of the Québec Court of Appeal composed of Justices Guy Gagnon, Peter Kalichman, and Christian Immer. The ARQ had issued tax assessments against Varadi covering the years 2014 to 2017, which the trial judge only partially set aside. Varadi challenged this outcome on three grounds: first, that the ARQ was improperly allowed to assess beyond the normal three-year limitation period under paragraph 1010(2)(b)(i) of the Loi sur les impôts for the 2014 tax year; second, that an excessively heavy burden of proof was imposed on him to rebut the presumption of validity underlying certain assessments; and third, that a hearsay objection he raised was wrongly dismissed, allowing the ARQ to introduce evidence derived from a CRA audit.

Policy terms and statutory provisions at issue

The central statutory provision was paragraph 1010(2)(b)(i) of the Loi sur les impôts, which governs the normal reassessment period and the circumstances under which the tax authority may reassess beyond that three-year window. The trial judge found that Varadi's inability to explain the discrepancy between his actual income and his declared income — or to provide documentation to account for it — demonstrated a lack of diligence, indifference, and negligence with respect to his tax obligations, justifying assessment beyond the normal period on the basis that he had made a misrepresentation through neglect or wilful omission.

Court's reasoning and analysis

On the first ground, the Court of Appeal found no manifest and determinative error in the trial judge's conclusion that Varadi had made a misrepresentation through neglect or wilful omission, which permitted the ARQ to reassess for 2014 beyond the normal three-year period. The Court also upheld the trial judge's finding that the testimony of accountant M. Leduc was clearly insufficient, noting that his explanations were based entirely on hearsay. On the second ground, the Court confirmed that Varadi was not required to present corroborating evidence to demolish the presumption of validity; rather, as the trial judge correctly noted, he only needed to present prima facie evidence with a certain degree of probability and precision. Varadi failed to meet even this standard, having produced no documentary evidence and having given testimony found to be of low credibility. On the third ground, the Court held that the trial judge did not err in dismissing Varadi's hearsay objection regarding references to adjustments from the CRA audit, which had been conducted jointly with the ARQ. The Court reasoned that this evidence appeared not only in the ARQ's own audit report but had also been validated and endorsed by the ARQ, and therefore could not be treated as hearsay. The Court further noted, citing St-Georges c. Québec (Sous-ministre du Revenu), 2007 QCCA 1442, at paragraph 18, that the respondent may establish assessments by way of indicia, including those drawn from Canada Revenue files.

Ruling and overall outcome

The Québec Court of Appeal dismissed the appeal with costs. The successful party was the Agence du revenu du Québec. The decision confirms the validity of the ARQ's tax assessments against Peter Varadi for the years 2014 to 2017. No specific monetary amount was stated in the Court of Appeal decision.
