Executive Summary: Key Legal and Evidentiary Issues

• Dispute over whether Mr. Geroli’s gains from options and other securities should be characterized as business income rather than capital gains for Quebec tax purposes.
• Challenge to Revenu Québec’s expert report on securities and options, questioning its relevance, usefulness to the trial judge, and compliance with the rules on expert evidence.
• Concerns raised about the expert’s qualifications in securities, including the depth of his training and experience specifically in investment products.
• Allegations of partiality based on the expert’s status as an in-house fiscal specialist employed by the Agence du revenu du Québec.
• Procedural issue around when and how far a court may go, at a preliminary stage under article 241 C.p.c., in excluding or reshaping expert evidence before the hearing on the merits.
• Formal validity of the expert report, including whether it adequately discloses methodology and sources and meets article 238 C.p.c. requirements, and whether any deficiencies go to admissibility or only to weight.

Background and parties

The case arises from a tax dispute between an individual taxpayer, Pietro Hassan Geroli, and the Agence du revenu du Québec (ARQ). Mr. Geroli reported certain gains from his investment activities, including transactions involving call options and long-term equity anticipation securities (LEAPS), as capital gains. The ARQ subsequently reassessed him, requalifying those amounts as business income on the basis that his conduct resembled that of a trader or business operator rather than a passive investor. Mr. Geroli contests these new assessments before the Administrative and Appeal Division of the Court of Québec, in the civil practice chamber. The underlying merits concern how his investment income should be characterized for Quebec income tax purposes, but this particular judgment does not decide that issue. Instead, it focuses on a preliminary procedural and evidentiary dispute about an expert report the ARQ intends to use at trial.

The expert report at issue

To support its position on the characterization of the investment income, the ARQ sought to call Mr. Stéphane Séguin, a fiscal specialist with the ARQ since 2011, as an expert in securities. His written report addresses four main questions: how to describe Mr. Geroli’s investment behaviour; whether his options activities fall within investment or speculation; what the account agreement reveals about his investor profile; and what distinguishes call options as a financial product. In substance, the report lists factual data about the taxpayer’s trading, comments on the use of options and LEAPS, and links these instruments to an investor profile more commonly associated with active strategies and potentially speculative activity. From the ARQ’s perspective, this expert evidence would help the trial judge understand the nature of the products used by Mr. Geroli and the type of investor who usually employs such instruments, thereby supporting the argument that the gains are business income rather than capital gains.

The taxpayer’s challenge to admissibility

Before the hearing on the merits, Mr. Geroli brought a motion under article 241 of the Code of Civil Procedure seeking rejection of Mr. Séguin’s report. He argued that the report failed every key test of admissibility and form. Substantively, he maintained that the report was irrelevant, unhelpful to the trial judge, and amounted to a legal opinion or disguised advocacy rather than neutral expert assistance. He also questioned whether Mr. Séguin had the necessary expertise in securities and options, given his background primarily in fiscal work, and argued that the report displayed a lack of impartiality because the expert is employed by the ARQ. Formally, he criticized the report’s “telegraphic” drafting style, alleged that it did not adequately expose any analytical method, and pointed to the absence of external references or sources as further grounds for exclusion. The motion thus invited the Court to exercise its gatekeeping role at an early stage and either strike the report in whole or refuse its filing in its current form.

Legal framework for rejecting expert evidence before trial

The Court, presided over by Justice Nathalie Chalifour, began by recalling the four core criteria for admissibility of expert evidence in Quebec civil procedure: relevance to the issues; necessity or usefulness to the trial judge on matters beyond ordinary knowledge; absence of a specific exclusionary rule; and the expert’s competence in the field. These principles are applied in light of article 231 C.p.c. (on expert assistance to the court) and articles 241 and 294 C.p.c., which govern the management of expert evidence and allow for pre-trial challenges to expert reports. Drawing on the Court of Appeal’s decision in Excavations Payette Ltée v. Ville de Montréal, and the Supreme Court of Canada’s reasoning in White Burgess, the judge emphasized that while early intervention can promote proportionality and efficiency, prudence remains essential. The Court of Appeal has cautioned that some objections—particularly those touching on relevance, necessity, or fine distinctions between admissibility and weight—may be better left to the trial judge, who will have the full evidentiary context. At the same time, White Burgess confirms that trial courts must exercise a real gatekeeping function and not simply admit all expert opinion on the theory that weaknesses always go only to weight. The challenge is therefore to balance efficiency with fairness and to distinguish the rare cases where pre-trial rejection is justified from those where issues should be determined at the hearing on the merits.

Analysis of relevance and usefulness of the report

Applying these standards, the Court closely examined each of the four questions in the report. It held that the section addressing question 1—asking how to “qualify” Mr. Geroli’s investment behaviour—did not truly fall within expert territory. There, the expert listed various factual elements about the taxpayer’s trading and then effectively assumed the role of the judge by concluding that the activities were commercial and amounted to an “enterprise”. That type of conclusion, in the Court’s view, trespasses on the ultimate legal characterization reserved to the decision-maker. Those factual elements, to the extent they are contested, must be proved through appropriate witnesses, and the judge will then apply the legal criteria to determine whether there is business income or capital gains. Because question 1 forced Mr. Séguin to deliver what is essentially a legal opinion and to answer the central question before the court, the judge found that this portion of the report lacked proper usefulness and should be excised. By contrast, the Court was prepared to accept that the remaining questions—if properly framed—could provide helpful context. The workings of call options and LEAPS, their strategic use in the market, and the type of investor profile generally associated with such products are not matters within the ordinary knowledge of a judge. An explanation of these instruments, their objectives, and the profile of investors who typically employ them was seen as prima facie helpful to understanding the nature of Mr. Geroli’s investment activities. To keep this within proper bounds, however, the Court directed that the questions be reformulated in neutral terms. Question 2 should ask whether options and LEAPS are investment or speculative instruments in general, without asking the expert to label Mr. Geroli’s specific conduct. Question 3 should ask to which general investor profile the taxpayer’s brokerage profile corresponds, rather than inviting bare factual recitation. Question 4 should simply seek an explanation of the distinctive elements of call options. On this narrowed and neutral basis, the Court considered that Mr. Séguin’s opinion could assist the judge without displacing the judicial role in characterizing the income.

Assessment of qualifications and alleged partiality

On the issue of competence, the Court reviewed Mr. Séguin’s academic and professional background. He holds a Bachelor of Business Administration and an MBA in financial services from the Université du Québec à Montréal, as well as a graduate-level diploma in taxation from the Université de Sherbrooke and a CMA designation. Professionally, he has worked as a fiscalist at the ARQ since 2011. In the securities field specifically, he had earlier experience as a mutual fund administrator at BNP Paribas (Canada) Securities and had taken courses in securities at both the Université du Québec à Montréal and the Canadian Securities Institute. While this curriculum vitae does not demonstrate deep, specialized capital-markets experience in the way a career securities analyst or trader might, the Court emphasized that expert competence is assessed in relation to the specific subject matter of the proposed opinion. Given that Mr. Séguin is being asked to explain the nature and functioning of options and LEAPS and the typical investor profile for such products, the Court concluded it could not, at this preliminary stage, deny him the status of expert in securities. Any limitations in his background would more appropriately go to the weight the trial judge assigns to his evidence, after hearing cross-examination and any competing expert testimony. Regarding partiality, Mr. Geroli argued that because Mr. Séguin is employed by the ARQ, his independence is compromised. The Court rejected the idea that an employment or contractual link, by itself, disqualifies an expert. Citing White Burgess and related Quebec case law, it reaffirmed that such relationships are common and do not automatically create disqualifying bias. The question is whether the expert can and does provide independent, impartial assistance rather than advocacy. At this stage—and particularly once the mandate is corrected to focus on neutral, technical explanations—the Court found no basis to conclude that Mr. Séguin was necessarily partial. Concerns about tone or slant can be explored at trial and will influence the weight of his evidence rather than its admissibility, unless some particularly manifest bias emerges.

Formal defects and compliance with procedural rules

Formally, Mr. Geroli argued that the report did not comply with article 238 C.p.c., criticizing its short, telegraphic style, the absence of a detailed analytic method, and the lack of cited external sources. The Court found these objections insufficient to justify rejection. It held that the mandate to enlighten the Court on the nature of the investments can be inferred from the questions posed and that the report is intelligible. The lack of extensive references may diminish probative value, but it does not automatically render the report inadmissible. Nonetheless, in order to improve transparency and assist the trial judge, the Court authorized the ARQ to have the report amended not only to remove question 1 and its supporting pages and to reformulate questions 2, 3 and 4, but also to add a list of any external sources relied on for the expert’s opinion. This strikes a balance between maintaining useful expert assistance and ensuring compliance with best practices in expert reporting.

Disposition, outcome, and successful party

In its final orders, the Court partially granted Mr. Geroli’s motion to strike. It ordered the ARQ to correct Mr. Séguin’s expert report by deleting the first question and the pages specifically devoted to that question and by reformulating the remaining questions to reflect the Court’s guidance. It also authorized the ARQ to add a list of external sources used by the expert. Importantly, the Court granted Mr. Geroli the right to file a counter-expert report on the nature and functioning of call options and LEAPS within sixty days, ensuring that both sides can present technical evidence on equal footing. The judgment concludes with “frais à suivre”, meaning that costs are reserved for a later decision, typically at or after the judgment on the merits of the tax dispute. In this interlocutory ruling, the successful party is therefore Mr. Pietro Hassan Geroli, but only in a partial sense: he obtained the removal of the most intrusive part of the ARQ’s expert report and a narrowing and restructuring of the remaining opinion, along with leave to file his own counter-expertise. No monetary award, tax amount, damages or quantified costs are granted or fixed in this decision, and the total amount ordered in his favour cannot be determined from this judgment alone.
