Executive Summary: Key Legal and Evidentiary Issues

• Whether non-capital losses of a wound-up subsidiary are converted from Canadian dollars into the parent's elected functional currency in the hands of the subsidiary or the hands of the parent.
   
• Determining which provision governs first: subsection 88(1.1), which deems a subsidiary's losses to become the parent's, or section 261(16), which addresses differing reporting currencies on a wind-up.
   
• Establishing whether subsection 261(16) applies when the subsidiary's wind-up commences and concludes on the same date.
   
• Assessing whether losses not deducted in the relevant year still fall within the subsidiary's "Canadian tax results" under subsection 261(1).
   
• Interpreting whether subparagraph 261(7)(a)(i) requires conversion of non-capital loss pools using the spot rate for the subsidiary's last Canadian currency year.
   
• Resolving a dispute over the applicable exchange rate, and therefore the USD value, of losses totalling $2,693,199 CAD.

Facts of the case

STC Steel Technologies Canada, Ltd. appealed a reassessment of its taxation year ending December 31, 2021 under the Income Tax Act. Justice Jenna Clark of the Tax Court of Canada heard the appeal on June 10, 2026, in Toronto, Ontario, and issued judgment on August 12, 2026. A joint Statement of Agreed Facts formed the entire evidentiary record. The Appellant had elected a functional currency of USD in its tax return for its taxation year ending March 31, 2011. It was the sole shareholder of Kasle Steel of Canada Ltd., which had not elected a functional currency and therefore reported in CAD. Kasle LLC, a related non-resident entity, transferred all of its shares in Kasle Steel to the Appellant on December 2, 2020, giving the Appellant more than 90% ownership on that date. Winding-up of Kasle Steel commenced and concluded on that same date, with its last taxation year ending December 2, 2020 [the source states this year-end as December 31, 2020 in one paragraph of the Reasons, though it is consistently stated elsewhere as December 2, 2020], and its preceding taxation year having ended December 31, 2019. Kasle Steel incurred non-capital losses across several taxation years: $680,396 CAD for the year ending March 31, 2009; $1,949,761 CAD for the year ending March 31, 2010; $25,084 CAD for the year ending December 31, 2010; and $37,958 CAD for the year ending December 31, 2011, totalling $2,693,199 CAD. The parties agreed that these losses became those of the Appellant under subsection 88(1.1) of the Act and required conversion into USD, but disagreed on the applicable date and spot rate for that conversion.

Policy and legislative provisions at issue

The dispute centred on the interaction between subsection 88(1.1), which deems a wound-up subsidiary's non-capital losses to become those of the parent, and the functional currency reporting regime in section 261. According to the Appellant, subsection 261(16) did not apply because Kasle Steel's final taxation year ended on the same day the wind-up commenced, rather than after it, and it pointed to the definition of "Canadian tax results" in subsection 261(1) to argue that its nil income for that year took the losses outside the provision's scope. On this basis, the Appellant contended that subsection 88(1.1) should be applied first, with the losses deemed incurred by the Appellant in the years Kasle Steel originally incurred them, converted using the spot rates applicable in each of those periods (1.0158, 1.0158, 0.9946, and 1.017 respectively), producing a figure the Appellant put at $2,651,791 USD [the source describes this as the "total capital loss carry forward balance," though the surrounding discussion concerns non-capital losses throughout — this appears to be an inconsistency in the source document]. The Respondent relied on subsections 261(16), 261(5), and 261(7), arguing that these provisions deemed Kasle Steel into the functional currency regime for its taxation year ending December 2, 2020, requiring the losses to be converted at the spot rate for December 31, 2019 (1.29887), the last day of Kasle Steel's last Canadian currency year, yielding a reassessed figure of $2,073,494 USD.

Reasoning and analysis

Justice Clark held that subsection 261(16) applied to the Kasle Steel wind-up. The Court found that "commencement time" is distinct from a year-end date, and that the commencement of the wind-up necessarily preceded Kasle Steel's year end even where both occurred on December 2, 2020. This meant Kasle Steel's taxation year, which included the commencement time, fell within the scope of subparagraph 261(16)(a)(i), deeming subsection 261(5) to apply to it. The Court rejected the Appellant's argument that a nil "Canadian tax results" outcome removed the losses from the functional currency regime, finding that a nil result is itself a "Canadian tax result" and that the regime's engagement did not depend on a positive outcome. Once subsection 261(5) applied, Kasle Steel's relevant taxation year became a "functional currency year," triggering subsection 261(7), which requires conversion of amounts deductible under section 111 using the spot rate for the last day of the taxpayer's last Canadian currency year. The Court found the non-capital losses fell within this provision because they remained available for deduction, even though not actually deducted. Reviewing the French text alongside the English "may be deducted," the Court concluded both versions extended to amounts capable of being deducted. The Court also considered the Explanatory Notes to section 261 and the Federal Court of Appeal's discussion of subsection 88(1) wind-ups in Canada v. Quebecor Inc., finding that conversion in the hands of the subsidiary, immediately before wind-up, was consistent with the scheme of the Act and did not render paragraph 88(1.1)(c) redundant, since that provision still governed the transfer of the losses to the parent once converted.

Ruling and overall outcome

The Court concluded that the Minister had correctly reassessed the Appellant's taxation year ending December 31, 2021, finding the Appellant entitled to a non-capital loss deduction of $2,073,494 USD, consistent with the Respondent's position. As a result, the appeal was dismissed, with the Respondent as the successful party. On costs, the Judgment set out a timeline rather than a fixed award: the parties were given 30 days to reach agreement, failing which the Respondent would have a further 20 days to file written submissions and the Appellant a further 20 days to respond, with any submissions capped at 10 pages. The Judgment specified that if no agreement or submissions were filed within these periods, costs would be awarded to the Respondent in accordance with the Tariff. No specific monetary amount for costs was stated in the decision.
