Documenting a Clean Break: Winning a Windsor Departure Tax Review

The situation

Hodan had spent nearly three decades building a dental practice in Windsor. At sixty-one, she sold her professional corporation's shares to an associate, Tarek, and, with her spouse Khalil, a commercial landlord who owned several rental units around the city, decided to retire abroad permanently. They settled on Portugal, drawn by the climate and a lower cost of living, and began winding down their Canadian affairs a full year before the move: selling their family home, transferring management of two of Khalil's commercial properties to a local property manager, and formally deregistering from provincial health coverage.

Before leaving, their accountant flagged an important consequence of the move. Under the Income Tax Act, a person who ceases to be a resident of Canada is treated as having sold most of their property at fair market value immediately before departure, even though nothing was actually sold. This rule is commonly called the departure tax, and it exists to make sure Canada collects tax on the growth in value that occurred while someone was a resident, before that growth moves outside Canadian taxing reach. For Hodan and Khalil, the deemed disposition captured the accrued value in an investment portfolio and Hodan's retained interest in the professional corporation, producing a reported capital gain of roughly $700,000 on their emigration-year tax return. They paid the resulting tax and filed the year believing the matter was closed.

What the review found

Eighteen months later, a residency review letter arrived from the Canada Revenue Agency's international tax division. Because Hodan and Khalil still owned Khalil's remaining commercial rental property in Windsor, still held a storage unit while sorting out the family home's contents, and because Hodan had returned twice that first year for meetings tied to the wind-down of her professional corporation, the reviewer proposed treating the couple as ongoing factual residents of Canada for two additional years past the date they had claimed.

That distinction mattered enormously. Canada taxes residents on their worldwide income, not just Canadian-source income. If the CRA's position held, the couple's foreign investment income and a portion of the practice sale proceeds earned after the claimed departure date would be pulled back into Canadian taxable income, on top of the departure tax they had already paid on the deemed disposition. Portugal, meanwhile, was already taxing them as residents from the same date. Between the disputed worldwide income inclusion and the practice sale proceeds the CRA wanted reattributed to Canadian years, the amount in question came to roughly $650,000 in additional assessed tax — money that, absent relief, they would effectively have paid twice.

Residency for Canadian tax purposes is not simply a matter of counting days outside the country. The CRA and the courts look at the whole pattern of ties: where a person's spouse and dependants live, where their home is, their social and economic connections, and secondary ties like driver's licences, memberships, and bank accounts. Retaining a piece of Canadian real estate as an investment does not, on its own, make someone a resident — but if the file does not clearly separate an investment relationship from a residential one, a reviewer can read it that way, and the burden falls on the taxpayer to show otherwise.

What we did

1. Rebuilt the residency timeline from primary documents. We assembled a chronological evidence file: the closing date on the family home sale, the date provincial health coverage ended, the date Portuguese tax residency began, utility and lease records at the new address, and travel records showing the couple's actual presence in each country. A clear, document-backed timeline is far more persuasive to a reviewer than a narrative reconstructed after the fact.
2. Separated the investment property from residential ties. We prepared a memo distinguishing Khalil's retained commercial rental property, managed by a third party under a formal agreement, from any suggestion of an ongoing Canadian home. Investment real estate held at arm's length, with rent reported and managed professionally, does not indicate a taxpayer's personal residence the way a retained family home would.
3. Explained the return visits on their own terms. Hodan's two trips back to Windsor were tied to specific, dated professional corporation wind-down matters. We documented the purpose and duration of each visit and showed neither came close to the kind of sustained presence that would suggest an unbroken residential tie.
4. Applied the tax treaty's tie-breaker analysis. Canada's tax treaty with Portugal, like most of Canada's tax treaties, includes tie-breaker rules for situations where a person could otherwise be considered a resident of both countries at once. We worked through that analysis showing the couple's permanent home, and the centre of their personal and economic life, had genuinely shifted to Portugal as of the claimed date.
5. Filed a formal objection within the deadline. Once the CRA issued its proposed reassessment, we filed a notice of objection with the CRA's Appeals Division well inside the strict deadline for doing so, attaching the full evidentiary package rather than waiting for a further request.
6. Confirmed the original departure tax filing was correct as filed. Rather than reopening the deemed disposition calculation, we confirmed the original emigration-year return had captured the right assets at the right values, so the appeals officer could see the departure tax itself was not in dispute — only the later years wrongly swept into it.

The outcome

An appeals officer reviewed the file over several months and agreed the evidence supported the residency change on the date originally claimed. The proposed reassessment was vacated in full: no additional worldwide income was added back, and the practice sale proceeds earned after the departure date stayed outside Canadian taxable income. The departure tax the couple had already paid on the deemed disposition stood as originally filed, and no further amounts were owed.

The result spared Hodan and Khalil from the practical burden of being taxed as residents of two countries on the same income in the same years, a form of double taxation that treaties are designed to prevent but that still requires a taxpayer to actively demonstrate their position. Because the residency file had been built with contemporaneous records rather than reconstructed under pressure, the objection moved through the appeals process without escalating to the Tax Court of Canada, saving the couple the additional time and cost that formal litigation would have involved.

Khalil kept the remaining rental property under its professional management arrangement, and the couple's Portuguese tax filings, already aligned with the same emigration date, required no amendment. What began as a routine retirement plan turned into a lesson in how much weight the CRA places on paper trails — and how much a clean, contemporaneous one can do to protect a departing taxpayer.

The couple later said the most stressful part of the review was not the dollar figure but the uncertainty of not knowing, for several months, whether they would need to fight the matter in the Tax Court of Canada while still settling into a new country. Having the residency file already assembled meant the objection could be filed the same week the proposed reassessment arrived, rather than months later after scrambling to locate old records, lease agreements, and travel receipts from a move that had already happened years earlier.
