Living abroad does not automatically make you a Canadian tax non-resident. CRA uses a facts-and-circumstances residency test based primarily on your residential ties (Canadian home, family). Non-residents pay only Canadian-source income at withholding rates (CPP/OAS: 25% default, reduced to 15% for Mexico, 10% for Portugal under tax treaties). The departure T1 return, Section 217 election, and NR5 form are the tools for optimizing your Canadian tax position as an expat.

The transition period — year of departure plus two years following — is the highest-risk period for tax errors. A cross-border tax specialist (not a general accountant) is essential during this phase.

Key Takeaways

Living abroad does not automatically make you a Canadian tax non-resident. Canada taxes based on residency status, not citizenship — and residency is determined by a facts-and-circumstances test, not simply by counting days outside the country. Canadians who keep their primary residence in Canada, whose spouses and dependants remain in Canada, or who retain significant Canadian connections may remain factual residents — and file Canadian T1 returns on worldwide income — regardless of how much time they spend in Mexico, Portugal, or anywhere else. The first question is always: what is your actual residency status?
The key tie that determines residency is your principal place of abode — typically your Canadian home. A Canadian who sells their home, departs with their family, and establishes a permanent home abroad has severed the primary residential tie. A Canadian who retains their Canadian home (even renting it out), leaves temporarily, or returns frequently is more likely to remain a factual resident. CRA takes a holistic view of the entire tie pattern — secondary ties (provincial health card, bank accounts, club memberships, driver's licence) matter as a collective signal even if no single secondary tie is determinative.
NR73 is the tool to use when your residency status is ambiguous. Form NR73 (Determination of Residency Status on Leaving Canada) is a request to CRA to formally assess your residency status based on the facts you provide. CRA's response is not binding on either party, but it creates a defensible record of the analysis. If you have any uncertainty about whether you qualify as a non-resident, file NR73 before departing — not after. An unexpected CRA assessment years later claiming you remained a Canadian resident through an allegedly un-severed tie is a very difficult and expensive problem to resolve retroactively.
The departure return is the most consequential tax return you will file. In the year of departure, you file a T1 for the period from January 1 to your departure date, reporting all worldwide income earned to that date. This return also reports your deemed disposition on departure — the capital gains triggered by the departure tax rules on your non-registered assets. A cross-border tax specialist (not a general accountant) should prepare the departure return. The deemed disposition on a significant investment portfolio can produce a meaningful tax bill, and timing strategies (departure date election, specific identification of assets) can significantly affect the outcome.
CPP and OAS payments to non-residents are withheld at 25% by default — but tax treaties reduce this rate for most Canadian expat destinations. Mexico: 15% withholding on CPP/OAS. Portugal: 10%. Costa Rica: 25% (no treaty with Canada on this type of income). Panama: 25%. The difference between 25% and 15% withholding on $20,000/year of CPP and OAS is $2,000/year — real money over a multi-decade retirement. To obtain the treaty rate, notify Service Canada of your non-residency and provide your foreign address. The payer adjusts withholding to the treaty rate automatically once non-residency is established.
The Section 217 election is an under-utilized optimization for Canadians receiving CPP, OAS, RRIF, and pension income as non-residents. The election allows you to file a T1 return as a non-resident of Canada (covering only Canadian-source income, not worldwide income) and potentially reduce your effective tax rate below the standard withholding rate. It is particularly beneficial for retirees whose total Canadian income is modest — a couple receiving $30,000 CAD combined in CPP/OAS might pay 15% effective tax under a Section 217 election versus the 15–25% withholding rates that would otherwise apply. Have a cross-border tax specialist model whether the 217 election is beneficial for your specific income composition.
RRSP and RRIF strategy changes fundamentally when you are a non-resident. RRSP contributions require earned income from Canadian sources — which most non-residents do not have after departure. RRIF withdrawals (mandatory once you convert the RRSP after age 71) are subject to non-resident withholding at 25% for lump sums, with treaty-rate options for periodic payments. The NR5 process can establish reduced withholding on RRIF periodic payments. There is no one-size-fits-all RRSP strategy for non-residents — the optimal approach depends on your age at departure, the size of the registered account, your destination country's tax treaty, and your total income profile.
The 183-day deemed resident rule applies in both directions: Canadians living abroad who spend too much time in Canada can trigger Canadian residency for a year; and Canadians living in Mexico who spend more than 183 days there can trigger Mexican tax residency simultaneously. The worst outcome is dual residency — being taxable as a resident in two countries simultaneously, even if the tax treaty prevents double taxation. Careful day counting and documentation is important, particularly in the transition years around departure.
OHIP and provincial health insurance follow provincial rules, not CRA residency rules. Provincial health plans typically lapse after 6–7 months of continuous absence per year. Even a factual Canadian tax resident who spends more than 6–7 months in Mexico may lose Ontario OHIP, BC MSP, or their provincial equivalent. The health insurance gap must be addressed through private international health insurance regardless of CRA residency status — the two systems operate independently.
Filing returns correctly during the transition period (the year of departure and the two years following) is the period of maximum tax risk for Canadians going abroad. The departure return must capture the full deemed disposition. Subsequent years may require T1 non-resident returns (Canadian-source income only), Section 217 elections if applicable, NR5 applications for withholding optimization, and T1135 for the departure-year period if specified foreign property exists. The cost of a cross-border tax specialist during this period is a fraction of the tax errors and CRA assessments it prevents.

Canadian Expat Taxes: Key Facts for Canadians Moving Abroad

Factual resident — still taxed on worldwide income: If you maintain significant residential ties to Canada (Canadian home, Canadian spouse, dependants in Canada), CRA considers you a factual resident regardless of where you live physically. Factual residents continue to file T1 returns on worldwide income, maintain provincial health coverage (province-dependent), and are eligible for TFSA contributions.
Deemed resident — the 183-day rule: Individuals who do not have significant ties to Canada but spend 183 days or more in Canada in a tax year are deemed residents for that year. For Canadians living abroad: if you return to Canada for visits totalling 183+ days, you are taxed as a Canadian resident for that year on worldwide income.
Non-resident — severing ties test: To be a Canadian tax non-resident, you must sever significant residential ties: dispose of or rent out your Canadian home (the primary tie), ensure your spouse and dependants have also departed, and sever secondary ties (Canadian bank accounts, driver's licence, provincial health cards, club memberships). NR73 (Determination of Residency Status) asks CRA to confirm your non-residency — recommended before departing.
T1 departure return — final Canadian filing: In the year you become a non-resident, you file a departure T1 return reporting worldwide income to the date of departure. After the departure date, only Canadian-source income (rental, pension, interest) is subject to Canadian non-resident withholding or return.
CPP, OAS, and RRSP/RRIF as non-resident: CPP and OAS payments to non-residents are subject to 25% withholding tax, reduced to 15% for most treaty countries (Mexico: 15%, Portugal: 10%, Costa Rica and Dominican Republic: 25% unless treaty). RRSP and RRIF withdrawals: 25% withholding (lump sum), or treaty rate for periodic payments. The NR5 form requests reduced withholding based on expected income.
Section 217 election — pension income optimization: The Section 217 election allows non-residents receiving certain Canadian income (OAS, CPP, RRIF, superannuation) to elect to file a T1 return as if they were a resident, potentially reducing tax below the standard 25% withholding rate. The election is beneficial when your total Canadian income is below the amount that would attract more than 25% effective tax as a resident.
NR5 form — reduced withholding application: Non-residents can file NR5 (Application by a Non-Resident of Canada for a Reduction in the Amount of Non-Resident Tax Required to be Withheld) to request reduced withholding on CPP, OAS, RRIF payments, and rental income. CRA issues an authorization to the payer to withhold at a reduced rate. NR5 must be filed before the end of the year for the following year's payments.
T1135 continues as a non-resident — up to departure date: T1135 (Foreign Income Verification Statement) is required for residents who hold specified foreign property with total cost over CAD $100,000. Once you become a non-resident, T1135 requirements end — you are no longer filing as a Canadian resident. However, for the departure year, T1135 must be filed for the period of your Canadian residency if the threshold is met.
TFSA — contributions prohibited as non-resident: TFSA contributions are prohibited while you are a Canadian non-resident. Any contribution made while non-resident attracts a 1%/month penalty tax. Your TFSA can remain open, investments can grow tax-free, but no new contributions. Withdrawals are allowed (tax-free) and can be re-contributed if you later return to Canadian residence.
Departure tax — deemed disposition on departure: On your departure date, you are deemed to have disposed of most of your property at fair market value. This triggers capital gains on: non-registered investment portfolios, shares, foreign property, and certain other assets. Principal residence (Canadian home) is exempt if sold within a reasonable period. RRSP, RRIF, CPP, OAS, and TFSAs are excluded from departure tax.

The Residential Ties Test: What Determines Your Status

CRA's Income Tax Folio S5-F1-C1 provides the framework for determining Canadian residency. The primary tie is the one that matters most: a dwelling place in Canada that you maintain available for your use. If you own a Canadian home and have not rented it out or sold it, it is presumed available for your use — a significant tie that makes non-residency very difficult to establish.

Secondary ties are evaluated collectively. Canadian bank accounts, RRSP, Canadian driver's licence, provincial health card, club memberships, business interests in Canada, and Canadian passport are all secondary ties. No single secondary tie is determinative, but accumulation of secondary ties alongside a primary home tie typically produces a factual resident determination.

Pension Income as a Canadian Non-Resident

CPP and OAS are the foundation of most Canadian retirement income abroad. As a non-resident, these payments are subject to withholding at the treaty rate. The treaty rates for major Canadian expat destinations: Mexico 15%, Portugal 10%, United States 15% (periodic pension), Costa Rica 25% (no treaty benefit on this income type), Panama 25%. Notify Service Canada of your non-resident status and provide your foreign address — they adjust withholding automatically.

GIS (Guaranteed Income Supplement) is terminated when you are outside Canada for more than 6 months in a year. For low-income Canadian retirees who qualify for GIS (up to $1,065/month in 2026 for singles), this is a significant retirement income consideration. The GIS loss can offset all other cost advantages of retiring abroad for recipients near the eligibility threshold. See our guide on GIS eligibility when living abroad.

RRSP and TFSA Strategy for Canadian Expats

Before departing Canada: maximize RRSP and TFSA contributions in your final year of Canadian residency. RRSP contributions made as a resident contribute to tax-deferred growth that continues regardless of residency status. TFSA contributions made as a resident continue to grow tax-free — new contributions are prohibited after non-residency is established, so maximize the account before departure.

For RRSP deregistration timing: the conventional wisdom of deferring RRSP withdrawals as long as possible changes as a non-resident. Large RRIF withdrawals are subject to 25% withholding (or treaty rate) — which may be lower than your marginal Canadian tax rate as a resident would have been. There can be a case for accelerated RRIF withdrawals in the early retirement years when you are a non- resident, particularly if your destination country's treaty rate is favourable and your other income in that country is modest. This is a planning point for your cross-border tax specialist.

Frequently Asked Questions

Do I have to pay Canadian taxes when I live in Mexico full-time?

It depends on your Canadian tax residency status. If you remain a factual Canadian resident (keep your Canadian home, Canadian spouse remains in Canada, or maintain significant Canadian ties), yes — you file a full T1 return on worldwide income regardless of where you live. If you have severed significant ties and become a Canadian tax non-resident, your Canadian tax obligation is limited to Canadian-source income (CPP, OAS, RRIF withdrawals, Canadian rental income) at withholding rates, not full T1 filing. The answer is not determined by which country you are physically in — it is determined by your residency tie analysis. This analysis should be done with a cross-border tax specialist before you depart.

How do I become a Canadian tax non-resident?

To become a Canadian tax non-resident: (1) Sell or permanently rent out your Canadian home — this severs the primary residential tie. (2) Ensure your spouse and dependants also leave Canada or that you are not maintaining a home available for their use. (3) Sever secondary ties: cancel your provincial health card (notify the province), surrender your Canadian driver's licence (get a foreign one), close unnecessary Canadian bank accounts, resign from Canadian clubs and organizations. (4) File NR73 with CRA to request a formal determination of your departure date. (5) File a departure T1 return for the year of departure. You do not need to formally 'apply' to become a non-resident — it is a status that results from the facts.

What is the Section 217 election and who benefits from it?

The Section 217 election allows certain non-residents receiving Canadian pension, annuity, or RRIF income to elect to be taxed as a resident of Canada (on Canadian-source income only, not worldwide income). The benefit: if your total Canadian income is modest, the Canadian tax calculated under the election's 'as-if-resident' formula may be lower than the standard 25% withholding. A Section 217 election requires filing a T1 non-resident return by June 30 of the following year. To benefit, your 'net income' on the elected income (after applicable deductions) must result in a lower effective tax rate than the withholding rate. A cross-border tax specialist can quickly calculate whether the 217 election benefits you for a specific income profile — it is a routine optimization for many Canadian retirees abroad.

What is the NR5 form and should I file it?

NR5 (Application by a Non-Resident of Canada for a Reduction in the Amount of Non-Resident Tax Required to Be Withheld) is a form filed with CRA to request reduced withholding on Canadian-source income payments. When approved, CRA issues an authorization to your payers (Service Canada for CPP/OAS, your bank or broker for RRIF) to withhold at a lower rate. This is beneficial when: your actual tax liability is less than the default withholding rate, you want to receive more cash flow through the year rather than waiting for a refund, or you are receiving RRIF income that would otherwise be withheld at 25%. NR5 must be filed before December 31 of the year preceding the year of reduced withholding. Most cross-border tax specialists include NR5 preparation as part of their non-resident client service.

What happens to my TFSA when I move abroad?

Your TFSA account remains open and continues to hold investments — which continue to grow tax-free in Canada. What changes: you may not make any new contributions while you are a Canadian tax non-resident. Any contribution made while non-resident is subject to a 1%/month over-contribution penalty until withdrawn. The penalty tax is assessed by CRA on your annual T1 non-resident return or TFSA penalty tax return. Strategy: before departing, maximize your TFSA room with contributions — this shelters future growth from any Canadian tax. While abroad, leave the TFSA invested (do not make new contributions). If you return to Canada and re-establish residency, TFSA contribution room resumes accumulating. Withdrawals can be made at any time, even while non-resident — they are tax-free in Canada (though the foreign country may tax them).

Will I be taxed in both Canada and Mexico if I live in Mexico?

The Canada-Mexico tax treaty prevents full double taxation but requires careful management. As a Canadian tax non-resident in Mexico: Canada taxes only Canadian-source income (CPP, OAS, RRIF, Canadian rental) at withholding rates. Mexico may also tax this income as your country of residence (if you are a Mexican tax resident). The treaty provides mechanisms — Foreign Tax Credits — to prevent the same income from being taxed twice. However, the tax reduction depends on proper filing in both countries and claiming the treaty credit. This is the area where a cross-border tax specialist who knows both the Canadian T1 non-resident return and the Mexican SAT system is essential — generic accountants rarely have this cross-border expertise.

What is departure tax and how do I minimize it?

Departure tax is the capital gains tax triggered by the deemed disposition of your assets on the date you become a Canadian tax non-resident. On your departure date, you are treated as having sold most assets at fair market value — triggering capital gains on appreciated stocks, foreign property, and other non-registered assets. Excluded: RRSP, RRIF, TFSAs, CPP entitlement, OAS entitlement, principal residence (Canadian home — if sold before or shortly after departure), and employer pension entitlements. Strategy to minimize departure tax: (1) Time the departure date to optimize which tax year the gains fall in. (2) Dispose of highly appreciated non-registered assets before departure (crystallize the gains while still a resident at your marginal rate, if lower than departure tax treatment would produce). (3) Ensure principal residence is sold before departure to preserve the PRE. (4) Work with a cross-border tax specialist to model the departure tax under different departure date scenarios before setting the date.

Do I still need to file T1135 after I move abroad?

T1135 (Foreign Income Verification Statement) is required for Canadian tax residents who hold specified foreign property with total cost exceeding CAD $100,000. Once you become a non-resident, you are no longer a Canadian tax resident — and T1135 requirements do not apply to non-residents. However: in the year of departure, if you held foreign property during your period of Canadian residency, T1135 may be required for that period. After a clean departure establishing non-residency, T1135 is no longer relevant. If you are a factual Canadian resident living abroad (retained Canadian home, family in Canada), T1135 continues to apply — including for the foreign property you purchase abroad.

What is the best tax country to retire in from Canada?

The optimal destination from a Canadian tax perspective depends on your income composition. For pension-heavy retirees (CPP, OAS, RRIF): Portugal offers the 10% withholding treaty rate (lowest of all major Canadian expat destinations) — and historically offered the NHR (Non-Habitual Resident) regime, though this has been modified. Mexico: 15% withholding rate on CPP/OAS, no Mexican income tax on foreign-source pension income for those managing their Mexican tax residency status carefully. Panama: 25% withholding (no treaty), but Panama does not tax foreign-source income — your Canadian CPP/OAS withholding is final, and Panamanian income tax on foreign income is zero. Costa Rica: 25% withholding (no direct treaty benefit), no Costa Rican income tax on foreign pensions. For investment income: Portugal's tax treatment of foreign investment income under its replacement NHR program requires analysis. No single destination is best for all income types — model your specific income composition with a cross-border tax specialist.
