Leaving Canada Without Selling Everything First

The situation

Lan had spent twelve years building a surgical practice in Sault Ste. Marie through a professional corporation, supplementing hospital work with occasional telehealth consulting for patients across Northern Ontario through a gig-based virtual care platform. Her partner, Thalia, worked as a technology executive for a multinational firm. When Thalia was offered a senior regional role based overseas, the couple decided to relocate together, with Lan planning to continue some remote consulting work while establishing a new practice abroad.

What looked like a straightforward move became complicated once their accountant flagged something neither of them had thought about: leaving Canada is not just an immigration and logistics event. For tax purposes, it can be treated as though they sold almost everything they owned, on the day they left, whether they actually sold it or not.

Between a non-registered investment portfolio built up over a decade and the accumulated value inside Lan's professional corporation, the couple had unrealized gains of roughly $2.4 million sitting on paper. None of it was cash. All of it was about to be treated, for one specific purpose, as if it had been converted to cash the day they boarded a plane.

The residency problem

Under the Income Tax Act, a person who stops being a resident of Canada for tax purposes is deemed to have disposed of most of their property at fair market value immediately before leaving, and to have reacquired it at that same value. This is commonly called departure tax. It exists so that Canada can tax the growth in value that happened while someone was a resident here, before that person moves to a country that might tax the same gain differently, or not at all.

The mechanics create a real problem for people who are asset-rich but not holding cash to match. Lan and Thalia's investment portfolio and the retained earnings inside Lan's professional corporation had grown substantially over the years they lived in Sault Ste. Marie. Once the taxable half of those gains was calculated and taxed at the couple's marginal rate, the resulting departure tax bill came to approximately $650,000 — due with their return for the year they left, on assets they had no intention of selling and, in the case of the corporation, could not simply liquidate on short notice.

Two further complications sat underneath the main one. First, Lan intended to keep doing remote telehealth consulting for Canadian patients after the move, which meant continuing to earn Canadian-source income and raised a fair question about whether she had genuinely severed her residential ties to Canada or merely relocated her body while keeping her economic life anchored here. Residency for tax purposes is a factual determination built from ties like a home, a spouse, dependants, and habitual economic activity, not a single form or a date on a passport stamp. Second, the couple had not yet sold their house, planning instead to list it a few months after the move, which meant it would remain on the residency-ties ledger for a period after their departure date.

What we did

1. Established a clean departure date based on residential ties, not travel dates. We reviewed the sequence of events — the house listing, the school and health registrations being cancelled, the bank and mailing address changes, the timing of Thalia's new employment contract — and helped the couple document a departure date that reflected when their residential ties to Canada genuinely shifted, rather than an arbitrary flight date.
2. Calculated the deemed disposition and identified what was actually exposed. Not every asset is caught by the departure tax rules. Registered accounts and Canadian real property, for example, are generally excluded from deemed disposition treatment, even though the real property itself remains taxable in the ordinary way if later sold. We worked through the portfolio and the corporation's holdings line by line to confirm which assets were properly in scope and which were not, narrowing the taxable base before any tax was calculated.
3. Filed the election to post security instead of paying immediately. The Income Tax Act allows a departing taxpayer to elect to defer payment of the departure tax on qualifying property by providing CRA with adequate security, rather than paying the full amount with that year's return. We prepared and filed this election within the required deadline, along with a formal offer of security backed by a pledge over a portion of the investment portfolio that CRA's collections area found acceptable.
4. Addressed the continuing gig income separately from the residency question. We advised Lan on structuring her ongoing telehealth consulting so that it was properly reported as Canadian-source income taxable in Canada regardless of her residency status, without that income itself being treated as evidence that she remained a Canadian tax resident. Income earned in Canada by a non-resident is taxed here on its own terms; it does not automatically undo a genuine change of residency.
5. Coordinated the house sale and principal residence exemption with the departure timeline. Because the home was listed after the departure date, we set out clearly for the accountant how the principal residence exemption would apply for the years the couple lived in it, and how any gain accruing after the departure date would be treated differently once the property was no longer their tax home.
6. Worked alongside the couple's cross-border financial advisor, Yanni, to avoid double taxation. Yanni was coordinating the couple's tax position in their new country of residence. We shared the Canadian deemed disposition values and the security arrangement so that the foreign-side advisor could claim appropriate credit for Canadian tax ultimately paid, rather than the same gain being taxed twice with no relief on either side.

The outcome

CRA accepted the security election. Instead of finding roughly $650,000 in cash within months of relocating — money that would have meant selling investments at a time not of their choosing, or drawing down the corporation in a way that created its own tax consequences — Lan and Thalia were able to defer that liability with no interest accruing on the deferred amount, so long as adequate security remained in place. The pledged portion of the portfolio stayed invested and kept growing.

The deferral is not a discount and it is not forgiveness. The departure tax remains owing and becomes payable, in whole or in part, as the underlying assets are eventually sold, or if the security arrangement is no longer maintained. But it converts a forced, poorly timed liquidation into a manageable, self-timed one. Lan and Thalia settled into their new posting with their portfolio intact, a documented and defensible departure date on file, and a clear map of what would trigger payment down the road. The correspondence with CRA closed with the election formally accepted and no penalties assessed — a clean result built on catching the mechanics of departure tax before the filing deadline forced a worse outcome.
