In a landmark ruling within Canadian tax law, a Tax Court judge has faced the critical task of determining the treatment of cryptocurrency losses, specifically regarding a taxpayer’s claim related to her significant loss from bitcoin investments. This case marks the first documented Canadian tax situation involving cryptocurrency taxation.
The taxpayer, who had been aiming for early retirement in her 60s, ventured into the cryptocurrency market in 2017 by opening an account with QuadrigaCX, which at the time was Canada’s largest crypto exchange. QuadrigaCX’s abrupt and disastrous collapse in 2019, rooted in allegations of fraud and the sudden death of its CEO Gerald Cotten, set the stage for the taxpayer’s financial troubles.
According to the taxpayer, her QuadrigaCX account balance mysteriously disappeared in late 2017. After unsuccessful attempts to reclaim her funds, she filed a tax return claiming a non-capital loss of $505,142, which encompassed both her investment and various expenses associated with it. The Canada Revenue Agency (CRA) denied this claim, prompting her appeal to the Tax Court.
In her testimony, the taxpayer detailed her initial exposure to bitcoin through friends and family in 2016, noting the impressive returns seen by others. Motivated by the potential for substantial profits, she began investing through QuadrigaCX and accumulated over 100 bitcoin transactions, at one point valuing her account at over $2 million.
Her investment strategy entailed combining personal savings with borrowed funds, leading her to take high-interest credit card advances and a second mortgage, as well as withdrawing from her registered retirement savings plan (RRSP). The taxpayer reported an employment income of just over $95,000, along with her RRSP withdrawal of approximately $264,000 when she filed her 2017 tax return.
Following her losses, the taxpayer struggled with feelings of shame and isolation, only confiding in her son months later. Despite seeking expert advice on recovery options, her attempts to revive her QuadrigaCX account, including two subsequent $1,000 deposits, proved fruitless.
As the judge deliberated, they considered various theories surrounding the disappearance of the taxpayer’s funds, ranging from theft via hacking to potential fraudulent practices by QuadrigaCX. The Ontario Securities Commission’s 2020 report, which confirmed the fraudulent circumstances of QuadrigaCX’s collapse, served as a significant piece of evidence in the proceedings.
Ultimately, the judge had to establish not only whether the taxpayer had indeed incurred a loss due to her bitcoin investments but also whether that loss should be categorized as a capital or non-capital loss. The distinction is crucial because capital losses can only offset capital gains, while non-capital losses can reduce overall taxable income.
The judge determined that the taxpayer’s activities qualified as a legitimate business venture with a clear intent to make a profit, likening the modern cryptocurrency surge to historical economic frenzies. Despite recognizing some imperfections in her evidence, the judge ultimately ruled in favor of the taxpayer, concluding that the loss should be classified as a non-capital loss.
This decision has significant implications for future cryptocurrency tax cases in Canada, as it reflects the evolving landscape of digital asset taxation and offers a framework for how losses in this nascent industry may be treated under tax law.
