For Canadians who buy, renovate and sell homes, one Tax Court of Canada decision frames the central risk better than almost any other recent case: Hansen v. The Queen, 2020 TCC 102. The taxpayer, a builder, sold a series of houses over several years and claimed the principal residence exemption on each one. The Canada Revenue Agency disagreed, reassessed the gains as fully taxable business income, and added gross negligence penalties on top. The Court's answer was a split decision — and that split is exactly why the case is worth understanding before you sell a home you have not lived in for very long.
The decision matters because it shows that the same facts can produce three different outcomes at once: some years protected by the limitation period, some sales recharacterized as a business with the exemption denied, and penalties cancelled because the taxpayer acted in good faith. Each of those moving parts is decided on the evidence, not on a slogan about how long you owned the property.
The facts
The taxpayer was experienced in residential construction. Over a span of years running from roughly 2007 through 2012, he and his spouse acquired, occupied and then sold several houses, reporting each disposition as the sale of a principal residence and claiming the exemption so that no tax was payable on the gains. The CRA audited the pattern of transactions and took the position that the taxpayer was not an ordinary homeowner moving from house to house, but a person carrying on a business of building and selling homes — or, at minimum, engaging in an adventure in the nature of trade.
On that theory, the Minister reassessed multiple taxation years, denied the principal residence exemption, treated 100% of each gain as ordinary income rather than a capital gain, and assessed gross negligence penalties under the Income Tax Act. Several of the earlier years were reassessed only because the Minister opened them up beyond the normal reassessment period — something the CRA may do only where it can show a misrepresentation attributable to neglect, carelessness, wilful default, or fraud.
A key fact, and one the Court returned to repeatedly, was that the taxpayer had told his accountant about each transaction — what he bought, why he sold, and what he intended — and the accountant advised that the principal residence exemption applied. The accountant supported that account at trial.
The issue
Three distinct questions had to be answered, and they did not all rise or fall together:
- Characterization: Were the gains capital gains (eligible, in principle, for the principal residence exemption) or income from a business or an adventure in the nature of trade (fully taxable, with no exemption)?
- The limitation period: For the older years, could the Minister reassess at all? That turned on whether the returns contained a misrepresentation that opened the statute-barred years.
- Penalties: Even if some gains were taxable, were gross negligence penalties justified, or had the taxpayer simply made an honest mistake while relying on professional advice?
The first question is the one most homeowners assume is simple. It is not. The principal residence exemption only shelters a gain that is capital in nature. If the property was really trading stock — inventory acquired with a view to resale at a profit — the gain is business income, and the exemption never comes into play regardless of whether the family lived in the house.
What the Court decided (and why)
To sort capital from business income, the Court applied the well-established factors from Happy Valley Farms Ltd. v. The Queen — the standard checklist Canadian courts use to identify an adventure in the nature of trade. Those factors include the nature of the property sold, the length of the period of ownership, the frequency of similar transactions, work done on the property to make it more marketable, the circumstances of the sale, and — treated as especially important — the taxpayer's intention at the time of acquisition, including any secondary intention to resell at a profit if the opportunity arose.
Applying those factors, the Court reached a mixed result:
- The older years were protected by the limitation period. The Court held that the Minister could not reassess the 2007, 2008 and 2009 taxation years outside the normal reassessment period, because it was not satisfied there was a misrepresentation in those returns sufficient to open them up. Those reassessments could not stand.
- Two later sales were business income, and the exemption was denied. For the two properties at issue in the later years — referred to in the reasons as the Cedardown and Kilbirnie houses, sold in 2011 and 2012 — the Court found that, on the evidence, the taxpayer had a resale-for-profit purpose in mind when he acquired them. On that finding, those gains were income from a business or an adventure in the nature of trade. The principal residence exemption was not available, and the gains were fully taxable.
- The gross negligence penalties were vacated. This is the part of the decision taxpayers should not overlook. The Court drew the familiar line between an ordinary mistake and the high degree of negligence that gross negligence penalties require — conduct amounting to something close to an intentional disregard of the law. The taxpayer had been open with his accountant about every transaction and his reasons, did not conceal the gains, and genuinely believed he was reporting correctly when he followed the advice he received. On those facts, the conduct did not meet the demanding penalty threshold, and the penalties were cancelled.
In short, the Court agreed with the CRA on the core characterization point for the two later houses, agreed with the taxpayer on the limitation period for the early years, and agreed with the taxpayer that penalties were not warranted. The appeal was allowed in part.
Why this decision matters — practical takeaways
Hansen is a useful teaching case precisely because it refuses to give a one-line rule. A few practical lessons follow from it.
1. Living in a house does not, by itself, secure the exemption. The principal residence exemption shelters a capital gain. If the property was acquired with a resale-at-a-profit purpose, the gain can be business income even though the family occupied the home. Occupation is relevant evidence, but it is not a trump card.
2. Intention at the time of purchase is often the battleground. Because intention is so central, the dispute frequently turns on documents and testimony about why the property was bought — listings, financing, renovation plans, communications, and the surrounding circumstances. A contemporaneous record that supports a genuine plan to occupy long-term is far more persuasive than an after-the-fact explanation. For taxpayers facing this kind of review, the analysis overlaps heavily with the evidence and burden issues discussed in our guide on evidence and the burden of proof in the Tax Court.
3. The limitation period is a separate fight with its own rules. Even where a gain is taxable, the CRA cannot always reach back into older years. To reassess beyond the normal period, the Minister must establish a qualifying misrepresentation — and, as Hansen shows, that is not automatic. Many net worth and lifestyle audits sweep in years that may, on closer analysis, be statute-barred.
4. Penalties are not a foregone conclusion. Recharacterization and penalties are different questions. A taxpayer can lose on whether a gain is taxable yet still defeat gross negligence penalties where the conduct reflects an honest error rather than a marked and substantial departure from the standard of a reasonable person. Genuine, fully informed reliance on a professional advisor can be central to that defence.
5. New rules tighten the landscape going forward. Hansen was decided under the general capital-versus-income analysis. For dispositions after 2022, Canada also has a residential property-flipping rule that deems gains on housing held for less than 365 days to be business income (subject to limited life-event exceptions), with the principal residence exemption unavailable. That statutory rule sits on top of — not in place of — the older case law, so the intention analysis in cases like Hansen still governs many transactions, including longer holds.
How Barrett Tax Law approaches principal residence and property-flipping files
Files in this area are won or lost on evidence and sequencing, and we approach them in that order. We start by mapping each disposition against the limitation period to see which years the CRA can actually reassess, because closing off statute-barred years can resolve a large part of an assessment before the characterization debate even begins. We then build the intention record property by property — the documents and testimony that show why each home was acquired and sold — and we treat the penalty question as its own issue, because a taxpayer who acted honestly and relied on proper advice should not be carrying gross negligence penalties.
Depending on the posture of the file, that work runs through audit representation, a Notice of Objection, or an appeal to the Tax Court of Canada, and our overview of the Tax Court appeal process sets out how those steps fit together. Where prior years were not reported and the conduct exposes a client to penalties, an early voluntary disclosure may be the better path than waiting for an audit.

Frequently asked questions
Does living in a house mean I can always claim the principal residence exemption when I sell it?
No. The exemption only shelters a gain that is capital in nature. If the Tax Court finds you acquired the property with a purpose of reselling it at a profit, the gain can be treated as business income or an adventure in the nature of trade, and the exemption is unavailable even though you lived there. Hansen v. The Queen, 2020 TCC 102, denied the exemption on two homes on exactly this basis.
What did the Court actually decide in Hansen v. The Queen?
It split the result. The Court held the earlier 2007-2009 years could not be reassessed because they were outside the normal reassessment period with no qualifying misrepresentation; it found two later sales (the Cedardown and Kilbirnie houses, 2011 and 2012) were business income, so the principal residence exemption was denied; and it cancelled the gross negligence penalties. The appeal was allowed in part.
How does the CRA decide whether a home sale is a capital gain or business income?
Courts apply the factors from Happy Valley Farms Ltd. v. The Queen, including the nature of the property, how long it was owned, how often similar transactions occur, work done to make it saleable, the circumstances of the sale, and — most importantly — the taxpayer's intention when acquiring the property, including any secondary intention to resell at a profit.
Why were the gross negligence penalties cancelled even though the taxpayer lost on the exemption?
Characterization and penalties are separate questions. Gross negligence penalties require conduct amounting to a high degree of negligence, close to intentional disregard of the law. In Hansen the taxpayer disclosed every transaction and his reasons to his accountant, did not conceal the gains, and reasonably believed he was reporting correctly. That honest, fully informed reliance did not meet the penalty threshold.
Can the CRA reassess old years if it thinks I wrongly claimed the exemption?
Not automatically. To reassess beyond the normal reassessment period, the Minister must establish a misrepresentation attributable to neglect, carelessness, wilful default, or fraud. In Hansen the Court found the older years could not be reopened. Whether a given year is statute-barred is a distinct issue that can resolve part of an assessment on its own.
Do the new property-flipping rules change the analysis in cases like Hansen?
They add to it. For residential property dispositions after 2022, a flipping rule deems gains on housing held under 365 days to be business income (with limited life-event exceptions) and removes the principal residence exemption. That statutory rule sits on top of the existing case law, so the intention-based analysis in Hansen still governs longer holds and many other transactions.
