Executive Summary: Key Legal and Evidentiary Issues

• Legitimacy of a $120,000 capital gains provision claimed by a fiduciary trust under article 234(b) of the Loi sur les impôts.

• Dispute over whether sale proceeds were actually payable after the end of the 2017 tax year.

• Applicability of the presumption of validity in Revenu Québec's tax reassessment under article 1014 L.i.

• Procedural compliance concerning fiduciary representation and the requirement to act through counsel.

• Interpretation of ambiguous contract language and its effect on taxation timing.

• Weight of documentary and testimonial evidence in establishing payment timing and accounting inconsistencies.

Facts of the case

In Trudeau (Fiducie Stratégies fiscales) c. Agence du revenu du Québec, 2025 QCCQ 1138, Daniel Trudeau, acting as trustee of the Fiducie Stratégies fiscales, challenged a revised tax assessment issued by Revenu Québec. The dispute centered on the denial of a $120,000 provision claimed against a capital gain reported in 2017. The gain stemmed from the sale of the Fiducie’s interest in a partnership (CMPG), first to Trudeau himself, and then on the same day, from Trudeau to a third-party company, Olympe Remorquage Inc.

Revenu Québec disallowed the provision on the basis that there was no evidence the sale proceeds were payable after the end of the 2017 tax year, which is a legal requirement for such a deferral under article 234(b) of the Loi sur les impôts (L.i.). Trudeau argued that the use of the term “solde” (balance) in the contract implied deferred payment, entitling the trust to spread the gain over multiple years.

Procedural issue regarding representation

Before addressing the tax dispute, the court examined whether the initial appeal was validly brought, since it was filed without a lawyer. Under article 87 of the Code de procédure civile, fiduciaries must generally act through legal counsel. The court accepted that this procedural defect was curable under article 92 CPC, particularly since Trudeau later retained a lawyer and acted in good faith. It also clarified that since a fiduciary represents a trust—which is not a legal person—the defect did not render the appeal null.

Legal analysis of the provision

The court closely reviewed the relevant sale contract, especially clause 1.2, which stated that the vendor (the Fiducie) acknowledged receipt of the full sale price on December 30, 2017. The judge found this language unambiguous: the payment was made within the same tax year, eliminating the possibility of deferring the gain. The court noted that prior transactions had clearly indicated deferred payment methods—such as promissory notes—which were absent in this case.

Trudeau’s attempt to reinterpret the clause as implying a future payment was rejected. The court emphasized that as both the author and beneficiary of the document, Trudeau bore the consequences of its ambiguities under article 1432 of the Code civil du Québec. Further, Revenu Québec's auditor highlighted the absence of any traceable deferred payment in the financial records, and no note receivable or accounting entry supported Trudeau’s claim.

Presumption and burden of proof

Although taxpayers typically bear the burden of disproving the factual assumptions behind a tax assessment, this case involved a mixed question of fact and law. Therefore, the presumption of validity under article 1014 L.i. did not apply. As such, Revenu Québec had to justify its denial of the provision, which it did successfully through audit documentation and testimony.

Outcome

The Court of Québec upheld Revenu Québec’s decision and dismissed the Fiducie’s appeal. The judge concluded that no part of the sale price was payable after the end of the 2017 tax year, and therefore the Fiducie was not entitled to the $120,000 provision. Both parties were ordered to bear their own costs. This decision underscores the importance of precise contractual drafting and proper documentation in supporting deferred tax treatment under Québec tax law.
