While 105,000 Americans type « how to move to Canada » into Google every year, the U.S. tax code, for its part, will never let them go. Here is what that means for the Cleveland doctor unpacking in Sherbrooke and the New York executive dreaming of a cottage life in the Eastern Townships.
On May 27, 2025, public broadcaster NPR ran a story that traveled across North America. Michael, an emergency physician born, raised, and trained in the United States, had just packed his family and crossed the border to work in a small Canadian hospital. NPR and KFF Health News granted him anonymity « because of fears he might face reprisal from the Trump administration if he returns to the U.S. ». The word reprisal, for an American doctor stepping into the doorway of a rural emergency room in Manitoba. That is the image now circulating through medical staff rooms on both sides of the border.
Michael is not an outlier. The Medical Council of Canada confirmed that the number of American doctors creating accounts on physiciansapply.ca, typically the first step toward Canadian licensure, jumped by 750 % in seven months, from 71 to 615 applicants. The College of Physicians and Surgeons of Ontario alone received roughly 260 licensure applications from U.S.-trained doctors in the first quarter of 2025, registering 116 of them, an increase of at least 50 % over the prior two quarters. British Columbia tripled its number of licenses granted to American doctors over the same period.
The exhaustion runs wider than white coats. According to the cultural intelligence platform Country Navigator, over 105,000 Americans search Google annually for how to move to Canada, nearly double the number for the second-place country, New Zealand, with its 60,900 annual searches. A moveBuddha survey released in 2026 places Canada at the top of relocation destinations Americans are considering, chosen by 24.4% of respondents, well ahead of England at 12.2%.
And the official numbers follow. According to data from the Immigration and Refugee Board of Canada reported by Reuters, 245 Americans filed asylum claims in the first half of 2025, already more than the 204 claims filed in all of 2024, and more than any full year since 2019. An Ottawa-based immigration consultant reported her American caseload jumping from 10 applications a month to 100: a tenfold increase. Quebec’s national archives, for their part, recorded a 3,000 % surge in requests for vital records between January 2025 and January 2026, according to CBC News, after Bill C-3 of December 2025 reopened the door of Canadian citizenship to a vast generation of descendants of Canadians born abroad.
Let us settle one thing. This article is not a welcome ceremony. It is a warning.
The blue passport does not go quietly into a drawer
For a U.S. citizen, moving to Canada closes no doors on the tax side. The United States is, alongside Eritrea, one of only two countries in the world that tax their citizens on their worldwide income, regardless of where they live. You leave Boston for Sherbrooke, but you still have an obligation to file an annual return with the IRS. You earn 200,000 $ in Quebec? The IRS wants to know. Are you selling your condo in Granby? The IRS wants to know. Do you receive dividends on Canadian stocks? The IRS wants to know.
The only way to sever the tie is to formally renounce your U.S. citizenship. And that is where the U.S. tax code bares its teeth.
The exit tax: the parting bill
Since the HEART Act of 2008, section 877A of the Internal Revenue Code (IRC) imposes an expatriation tax on covered expatriates: those citizens who renounce and exceed certain thresholds. The statute is blunt: « All property of a covered expatriate shall be treated as sold on the day before the expatriation date for its fair market value ». Plain-English translation: the day before your renunciation, the U.S. tax authority deems you to have sold absolutely everything you own worldwide at fair market value, and taxes the resulting gain.
Who is a covered expatriate? Under IRC § 877(a)(2), three tests, and failing any one of them is enough:
- Net worth test: your worldwide net worth equals 2 million U.S. dollars or more on the expatriation date. Home, IRA, Roth IRA, 401(k), brokerage accounts, business interests, all of it counts.
- Tax liability test: your average annual federal income tax liability over the prior five years exceeds 206,000 $ for 2025 expatriations.
- Compliance test: you cannot certify under penalty of perjury, on Form 8854, that you have complied with all U.S. federal tax obligations for the five years preceding expatriation.
This last test is the silent trap. Even if your wealth and average tax liability fall under the thresholds, simply being unable to certify five years of clean compliance flips you into covered expatriate status. For the family doctor who missed an FBAR three years ago, that is the tax-side descent into hell at the exit door.
For the New York executive with 4 million dollars in assets, the bill is concrete. The day before renunciation, the IRS calculates the unrealized gain on all of his worldwide assets. The exclusion for 2025 stands at $ 890,000 in net gain. Anything above that threshold is taxed immediately at long-term capital gains rates: 15% to 20%, plus the Net Investment Income Tax of 3.8%. On 4 million of unrealized gain, after the exclusion, the bill comfortably approaches half a million dollars. Payable in cash. Before departure.
Retirement accounts: the deferred cut
The American executive who imagines packing his IRA and 401(k) « as is, in a suitcase » discovers another layer. For a covered expatriate, tax-deferred accounts such as IRAs, HSAs, and 529 plans are treated as fully distributed on the day of expatriation and taxed at ordinary income rates. The 401(k) follows a parallel regime for eligible deferred compensation, with a 30 % U.S. withholding tax at source on future distributions.
For the emergency physician who keeps his U.S. citizenship and settles in Saskatoon, the mechanics are different, more tolerable, but still not trivial. The 401(k) can be left with the former employer or rolled into an IRA with continued tax deferral. The Canada-U.S. tax treaty, at its Article XVIII, paragraph 7, also allows the taxpayer to file a one-time treaty election to defer Canadian tax on the growth of a Roth IRA. But beware: this election should normally be filed with the first Canadian return after arrival. If missed, the CRA may sometimes accept a late or protective filing, but the ground turns soft and uncertain. The Roth growth can then become taxable in Canada year by year.
For the TFSA (the Canadian Tax-Free Savings Account, the rough equivalent of the U.S. Roth) that so many American newcomers want to open on arrival, the verdict is unforgiving. Opening a new TFSA as a U.S. person is never advisable: the paperwork stack (FBAR, Form 8938, PFIC rules on mutual funds inside the account, and possibly Form 3520 depending on the interpretation adopted, since the IRS has not clearly ruled whether every TFSA constitutes a foreign trust under § 6048) wipes out the Canadian benefit entirely. The Ohio cashier who has become a resident of Drummondville and opened a TFSA thinks she is getting ahead. In reality, she is exposing herself to potential penalties of up to 10,000 $ U.S. per missed form.
The real estate left behind: the debt that stays
The emergency physician who keeps his Detroit house and rents it out before leaving for Sherbrooke enters another labyrinth. As a Canadian tax resident, he must declare U.S. rental income in Canada (worldwide income), and declare the same income to the IRS (U.S. citizen). The tax treaty grants primary taxation rights to the United States on real property located on U.S. soil, and Canada grants a foreign tax credit to avoid double taxation.
For someone who does not hold U.S. citizenship and owns a rental property in the United States, the default withholding rate is 30% on gross rental income, unless Form W-8ECI is filed with the tenant or property manager to elect taxation on a net basis with deductions. The form is free. Ignorance, on the other hand, costs one-third of the gross monthly rent.
And on the day this same owner decides to sell? Welcome to FIRPTA, the Foreign Investment in Real Property Tax Act. The buyer must withhold 15 % of the gross sale price and remit it to the IRS, subject to specific exceptions. On a sale of $ 600,000 U.S., that means $ 90,000 U.S. is siphoned off in automatic withholding at closing. The seller must then file a 1040-NR the following year to recover any overpayment. Months of waiting to get your own money back.
The Substantial Presence Test: the trap of the return visit
This section does not address the emergency physician who keeps his U.S. citizenship, but two other profiles. The first: the American who renounced citizenship to settle permanently in Canada. The second: a Canadian who never became a U.S. citizen but who spends a lot of time south of the border (snowbird, student, professional on assignment, spouse of a U.S. resident). For a U.S. citizen still walking around with a blue passport, the test changes nothing: he is already taxable on his worldwide income by virtue of citizenship alone. For the other two profiles, however, the SPT can, mechanically, push you into the category of U.S. tax residents.
The rule is codified at § 301.7701(b)-1(c) of the Treasury Regulations. An individual satisfies the test if physically present in the United States for at least 183 days over a three-year rolling period. But the formula is not straight addition. Each day of the current year counts as a full day. Each day of the first preceding year counts as one-third of a day. Each day of the second preceding year counts as one-sixth of a day.
In concrete terms, if you spend 122 days in the United States three years in a row, the calculation gives 122 + (122 ÷ 3) + (122 ÷ 6), which equals exactly 183 days. You have just flipped into resident alien status, and the IRS considers you taxable on your worldwide income for that year. The regulation gives this exact example in its text. There is no rounding error: the threshold is calibrated to roughly one month of average presence per year. For a former American now Canadian, or for a Canadian snowbird wintering in Florida three months a year, the accumulation adds up fast.
There is an escape hatch: the closer connection exception under § 301.7701(b)-2, which lets an individual who has met the SPT remain a non-resident if he proves a tax home and closer ties to another country. But the exception requires fewer than 183 days in the current year alone and the timely filing of Form 8840. One more piece of paperwork not to forget.
The obligations that never go away
For the emergency physician who keeps his U.S. citizenship, the annual stack looks like this. A U.S. Form 1040 to file every year. An FBAR (FinCEN 114) must be filed if all Canadian financial accounts combined exceed $ 10,000 U.S. at any point during the year. A Form 8938 (FATCA) to attach to the 1040 if specified foreign financial assets exceed the applicable thresholds (200,000 $ U.S. on the last day of the tax year for a single filer residing abroad). And depending on holdings: Form 3520 (foreign trusts), 8621 (PFIC), 5471 (controlled foreign corporations).
Add to this the ordinary Canadian filings: federal T1, provincial return, and T1135 if specified foreign property exceeds $ 100,000 CAD at cost.
Two tax authorities. Two systems of filing. Two sets of penalties. A non-willful FBAR penalty can reach 10,000 $ U.S. per year. A willful penalty climbs to $ 100,000 U.S. or 50% of the account balance, whichever is greater. For a physician who has piled up five years of RRSPs, TFSAs, and Canadian bank accounts undeclared to the IRS, the theoretical bill climbs into six figures.
The emergency physician who remains a U.S. citizen can keep this machine running with the help of a cross-border accountant. Typical annual cost to file both sides and keep the file clean: 3,000 to 8,000 $ a year. A recurring expense that never disappears. Never.
The good news, and there is some
Not everything is downhill. The Canada-U.S. tax treaty does a lot of quiet work in the background. The foreign tax credit prevents double taxation on most employment and investment income. American pensions (Social Security, IRA, 401(k)) can be properly credited or deducted with proper planning.
And the Canadian effective tax rate, for a family doctor switching from a Cleveland practice to a Saskatoon practice, is not the catastrophe the legend claims. The taxes are higher, yes. But health coverage, CPP/QPP, and the absence of the $ 1,600 per month in Blue Cross Blue Shield premiums (a figure often mentioned by African-American voices in the source material) change the underlying math. Many American expats earn less gross but pocket more disposable income. The middle-class home in Saguenay remains affordable, whereas its Cleveland equivalent has been forever out of reach. Illness does not bankrupt. Public school works. The corner 7-Eleven has a lottery counter, not a wall of ammunition.
The lesson for those looking north
When it is all said and done, the U.S. tax code was designed to discourage departure. That is its function. The $ 2 million and $ 206,000 thresholds mainly capture upper-middle-class professionals and high-net-worth individuals. For an Indiana primary-school teacher who leaves with 80,000 $ in savings and a small 401(k), the exit tax will never bite. But the Manhattan lawyer, the San Francisco cardiologist, the software engineer at 700,000 $ a year, the heir to a family portfolio: those people will weigh every dollar before signing their Form 8854.
Planning upstream changes everything. A gift to the children before expatriation, properly structured. A sale of appreciated assets before the pivot year, to stay under the average tax threshold. A renunciation delayed by a year to spread it out. A timely election filed for the Roth IRA. A W-8ECI letter is sent to the property manager starting in the first month of the rental.
Without preparation, the departure becomes a tax-side Denver boot. You have physically left. The code, for its part, holds your front wheel to the ground.
The America of 2026 is driving its own citizens out. The Cleveland doctor, the Yale professor, the emergency physician who asks for anonymity, the ordinary citizen who no longer wants his child to run active-shooter drills in primary school. They are arriving. They are welcome. Taking a bow on a life in the United States also means a few months of administrative hell and a tax bill that can come as a surprise. No one says it in the “welcome to Canada” TikTok videos.
We say it here.
