Executive Summary: Key Legal and Evidentiary Issues

• Timeliness of the assessment turned on when Revenu Québec is deemed to have “knowledge” of a property transfer under article 14.5 LAF, as opposed to the date of publication in the land registry.
• Qualification of the parties as “conjoints de fait” at the time of the transfer was governed by the special tax definition of “conjoint” in article 2.2.1 LI, creating an irrebuttable presumption once they continued to live together.
• The scope of a transferee’s solidary liability for a transferor’s tax debt under article 14.4 LAF depended on whether the transferee obtained an “avantage” because the consideration was less than fair market value.
• Evidentiary rules limiting the ability to contradict a written deed by testimony (arts. 2863–2865 C.c.Q.) were tested against the taxpayer’s attempt to explain a broader separation agreement not fully reflected in the notarial act.
• Assessment of credibility and documentary evidence was crucial to determining whether the taxpayer in fact renounced her share of proceeds from another immovable, thereby providing indirect but sufficient consideration.
• The presumption of validity of tax assessments (art. 1014 LI, via art. 95 LAF) was ultimately rebutted by the taxpayer’s prima facie proof that Revenu Québec’s factual assumptions on consideration and “advantage” were incorrect.

Facts of the case

Marie Denise Belzius and Jean-Joubert Vixama were de facto spouses who owned together an income-producing duplex located on rue Arthur-Buies in Montréal (the “Immeuble Arthur-Buies”). They also lived, with their three children, in a separate family home on rue Mastigouche in Repentigny (the “Immeuble Mastigouche”), also co-owned by them. While Mr. Vixama was under tax audit by the Canada Revenue Agency and then by the Agence du revenu du Québec (“ARQ”) for the 2013–2015 taxation years, he accumulated a significant provincial tax debt. Following these audits, ARQ issued tax assessments against him in 2019 for those years. He was therefore a “débiteur fiscal” at the relevant time. On 7 August 2017, Mr. Vixama transferred his undivided one-half interest in the Immeuble Arthur-Buies to Ms. Belzius. The notarial sale deed recorded that, as consideration, she assumed the outstanding mortgage balance on the property. No cash changed hands at the time of this transfer. The deed also claimed an exemption from municipal transfer duties (droits sur les mutations immobilières) on the basis that the transfer was between “conjoints,” even though the parties maintained they had, in substance, separated around that period and were reorganizing their patrimonial affairs. As part of a verbal separation agreement, they had decided that Ms. Belzius would ultimately keep the Arthur-Buies duplex, while Mr. Vixama would keep the Mastigouche family home. The Mastigouche property was sold on 28 June 2018. After repayment of the mortgage and expenses, net sale proceeds of about $114,619.40 were paid into a bank account in Ms. Belzius’s name. She then withdrew these amounts in cash and, according to both her evidence and that of Mr. Vixama, turned over essentially the entire balance to him, which he admitted using largely for gambling and during a period of personal and financial disarray. Ms. Belzius testified that, despite being 50% co-owner of the Mastigouche property, she kept none of these net proceeds, effectively renouncing her share in favor of Mr. Vixama as part of their overall separation arrangement.

Statutory framework and policy provisions

The central legal mechanism relied upon by ARQ was the solidary liability regime in articles 14.4 and 14.5 of the Loi sur l’administration fiscale (LAF). Article 14.4 LAF provides that where a debtor of tax (“débiteur fiscal”) transfers property to certain related persons—including a person with whom the debtor does not deal at arm’s length, a minor child, a spouse, or a person who becomes a spouse after the transfer—the transferee becomes solidarily liable with the transferor. This liability is for the lesser of: (a) the excess of the fair market value of the transferred property over the fair market value of the consideration given for it; and (b) the total fiscal debt the transferor owes for the year of the transfer and prior years. The provision also specifies how to value an undivided interest in property at fair market value by reference to the value of the whole. Article 14.5 LAF then authorizes the Minister to assess a transferee under article 14.4 within four years of the day on which the Minister “has knowledge of the transfer” of the property. The case thus turned on when ARQ was legally deemed to have knowledge of the Arthur-Buies transfer and on whether the consideration Ms. Belzius provided was less than fair market value. In addition, article 1.3 LAF imports the special income-tax definition of “conjoint” in article 2.2.1 of the Loi sur les impôts (LI) for purposes of article 14.4 LAF. Under article 2.2.1 LI, persons who live in a conjugal relationship and meet certain conditions are presumed to remain “conjoints” for tax purposes unless and until they live separate and apart for at least 90 consecutive days due to the breakdown of their union. This statutory definition, read together with article 2847 C.c.Q. on legal presumptions, created an irrebuttable presumption that Ms. Belzius and Mr. Vixama were still “conjoints” at the transfer date as long as they continued to cohabit and had not been separated for at least 90 days.

Arguments of the parties

ARQ conducted an asset review of Mr. Vixama once his tax indebtedness was established. It discovered that he had transferred his half interest in the Arthur-Buies duplex to Ms. Belzius on 7 August 2017. Using the municipal assessment roll, ARQ determined that the property’s assessed value was $349,700, with an outstanding mortgage balance of $257,750.32 at that time. On ARQ’s calculations, half of the assessed value ($174,850) minus half of the mortgage ($128,875.50) yielded equity of $45,974.50 associated with the transferred half interest. ARQ treated this equity as the “advantage” Ms. Belzius allegedly received because she paid only by assuming half the mortgage, with no payment for the additional equity. Mr. Vixama’s outstanding tax debt at the relevant time was $28,956.43; after accounting for certain payments, ARQ fixed the amount it sought from Ms. Belzius under article 14.4 LAF at $28,361.95. On 20 April 2023, ARQ issued assessment CT-088202 against her for that amount, asserting she was solidarily liable for her former partner’s tax debt as cessionnaire of his undivided half interest. In contesting the assessment, Ms. Belzius advanced three main arguments. First, she argued the assessment was out of time because ARQ had constructive knowledge of the transfer from the date of its registration in the land registry (8 August 2017), and the four-year limitation period in article 14.5 LAF should run from that date. Second, she claimed she was no longer a de facto spouse of Mr. Vixama at the time of the transfer, pointing to their verbal separation and to later indications in her tax return that she had no spouse as of 1 July 2018. Third, she maintained that, even if they were still considered conjoints and even if ARQ acted within time, the transfer was supported by sufficient consideration when viewed in light of the overall separation deal: she assumed the full mortgage on Arthur-Buies and, crucially, renounced her share of sizeable net sale proceeds from the Mastigouche property, all in favor of Mr. Vixama.

Court’s analysis on limitation period

On the limitation question, the Court held that ARQ had the burden to show that it issued the assessment within the four-year period from the date it had “knowledge” of the transfer of the Arthur-Buies property. Documentary evidence, including ARQ’s internal opposition memorandum and testimony from its representative, Raoul Gnikpo, established that ARQ became aware of the transfer on 29 November 2019. The Court rejected Ms. Belzius’s contention that the relevant date was the 8 August 2017 publication of the deed in the land registry. Referring to article 14.5 LAF, the judge emphasized that the statute expressly speaks of the day the Minister “has knowledge of the transfer,” not the date of land-registry publication. Under the Civil Code’s publicity regime, the registration of rights in the land register renders rights opposable and establishes priority, and for acquirers or publishers of rights it creates a presumption of knowledge. However, those provisions do not translate into a general presumption that ARQ, as tax authority, is deemed to know every registered transfer simply by reason of publication. The Court instead applied article 2944 C.c.Q., which establishes a simple presumption of the existence of an inscription but not knowledge by third parties such as ARQ. Given that the assessment against Ms. Belzius was issued on 20 April 2023 and ARQ’s actual knowledge dated from 29 November 2019, the Court concluded that the assessment was made well within the four-year window mandated by article 14.5 LAF. The assessment was therefore not time-barred, and the presumption of its validity under article 1014 LI (via article 95 LAF) remained in place unless rebutted on the merits.

Court’s analysis on conjugal status

Turning to whether the parties were “conjoints de fait” at the time of the Arthur-Buies transfer, the Court acknowledged that, on a purely factual and relational level, the evidence suggested the couple’s intimate relationship had effectively ended before August 2017. Ms. Belzius testified that they had been together since roughly 2004–2006 and that there had been a friendly separation formalized in some way “chez la notaire,” though the only concrete act was the August 2017 transfer of Arthur-Buies. Mr. Vixama recalled a key discussion on 17 May 2017, after which he no longer considered himself her spouse, though the two continued to live under the same roof at Mastigouche. Despite these indications, the Court found itself bound by the special statutory definition of “conjoint” in article 2.2.1 LI, incorporated into the LAF for article 14.4 purposes. Under that provision, individuals who have lived in a conjugal relationship and continue living together are deemed to remain conjoints until they have lived separate and apart for at least 90 days because of the breakdown of their union. In light of article 2847 C.c.Q., the Court characterized this as an irrebuttable legal presumption concerning “réputés” facts: once the criteria are met, no contrary evidence can dislodge the presumption. Even if, on the facts, the couple had morally and emotionally separated before the 7 August 2017 transfer, they were still living together and had not yet spent 90 days apart. Accordingly, for the sole purpose of applying article 14.4 LAF, the Court was obliged to treat them as conjoints at the moment of the transfer. This satisfied the relational condition in article 14.4 that the transfer be to a spouse or person with a specified dependent relationship.

Court’s analysis on sufficiency of consideration

The pivotal issue thus became whether Ms. Belzius had received an “avantage” because the fair market value of what she acquired—Mr. Vixama’s half interest in Arthur-Buies—exceeded the fair market value of the consideration she gave. Under the Larocque (Fiducie familiale Larocque) framework, the Court reiterated that article 14.4 LAF is a “draconian” provision and must be applied strictly: ARQ must demonstrate, among other things, that the fair market value of the transferred property exceeds the consideration received and that its underlying factual assumptions are correct. ARQ argued that the notarial deed showed only one form of consideration: assumption of the outstanding mortgage. It objected to Ms. Belzius’s and Mr. Vixama’s testimony insofar as it might contradict the written instrument by suggesting that other consideration existed. The Court, however, rejected this objection, citing articles 2863–2865 C.c.Q. The testimony did not seek to change the deed’s express terms or to add a new price; rather, it explained why no additional cash consideration was reflected in the transfer and described a parallel, verbal separation agreement under which the larger transaction between the parties included both properties. On the evidentiary merits, the Court found the testimony of both Ms. Belzius and Mr. Vixama candid, coherent and corroborated by bank statements and other documents. The figures presented by ARQ itself showed that the net equity in Arthur-Buies was approximately $91,949.68, while the net equity realized on the sale of Mastigouche was $114,619.40. The evidence further established that the entire Mastigouche net proceeds were deposited to Ms. Belzius’s account and then withdrawn in cash, and that she handed those sums over to Mr. Vixama. He confirmed receiving these funds and using them, including for gambling and to deal with a period of depression and substance issues. The Court accepted that Ms. Belzius, although a 50% co-owner, did not retain her half share—approximately $57,309.70—and that this effective renunciation in favor of Mr. Vixama was agreed between them after May 2017 and before the August 2017 transfer of Arthur-Buies. In the judge’s analysis, this renunciation operated as an indirect but real form of consideration supporting the transfer of Mr. Vixama’s half interest in Arthur-Buies to Ms. Belzius. The fact that the agreement was verbal and that the financial flows were completed after the property transfer did not, in the Court’s view, negate their character as part of the overall bargain between the parties.

Ruling and outcome

Having recognized that the assessment had been issued within time and that the statutory presumption of conjugal status applied, the Court focused on whether ARQ had met its ultimate burden to show that Ms. Belzius received a taxable advantage under article 14.4 LAF. The presumption of validity of tax assessments meant that Ms. Belzius had to offer prima facie proof that ARQ’s factual hypotheses—particularly that she obtained equity without adequate consideration—were wrong. The Court held that she did so by establishing, through credible testimony and supporting documents, that she renounced her half share of the Mastigouche proceeds and that this renunciation, valued at roughly $57,309.70, was at least equivalent to, and in fact exceeded, the $45,974.50 equity value ARQ claimed she received in Arthur-Buies. As a result, the Court concluded that the transfer of the Arthur-Buies half interest had been made for sufficient consideration, that Ms. Belzius did not obtain a gratuitous or underpriced advantage within the meaning of article 14.4 LAF, and that the conditions for solidary liability were therefore not met. ARQ was found not to have discharged its burden of proving, on a balance of probabilities, that its factual assumptions underpinning the assessment were well-founded. The Court accordingly dismissed ARQ’s evidentiary objection, allowed Ms. Belzius’s tax contestation, and annulled assessment CT-088202 in the amount of $28,361.95. In the result, the successful party was Marie Denise Belzius; she was fully relieved of the $28,361.95 tax claim and was also awarded her costs of justice, although the precise monetary value of those costs is not specified in the decision and cannot be determined from the judgment text.
