Expat Tax Residency in Canada

Canada imposes income tax on the basis of residency, not citizenship. The Canada Revenue Agency (CRA) determines whether an individual is a Canadian tax resident through a facts-based analysis rooted in decades of case law and codified in Income Tax Folio S5-F1-C1 [SC1]. A Canadian citizen living permanently abroad can be a non-resident for tax purposes; a foreign national who settles in Canada becomes fully taxable here. Understanding the applicable rules is essential before changing residential status in either direction.

How does the CRA determine whether someone is a factual resident?

The primary test for Canadian tax residency is common-law factual residence. Courts have interpreted "ordinarily resident" in the Income Tax Act (ITA) to mean the place where a person has a settled routine of life and to which they regularly return. The CRA applies a residential-ties analysis that distinguishes between significant ties (primary) and secondary ties [SC1].

Primary significant ties carry decisive weight. A dwelling place in Canada that remains available for the individual's use -- whether owned, leased, or accessible through family -- is the strongest single tie. Retaining a Canadian home while living abroad is, in most cases, sufficient to sustain factual residency on its own. A spouse or common-law partner remaining in Canada, and dependant children living in Canada, carry comparable weight.

Secondary ties are relevant only collectively; no single secondary tie is alone determinative. They include personal property in Canada (vehicles, furniture), provincial health insurance coverage, a Canadian driver's licence, active Canadian bank accounts and credit cards, professional or club memberships, and documented evidence that a return to Canada was foreseen at the time of departure.

What weight does the CRA assign to each type of residential tie?

What is the 183-day sojourner rule and who does it affect?

Separate from the factual-residence test, paragraph 250(1)(a) of the ITA deems an individual to be a Canadian resident for an entire calendar year if they sojourn in Canada for 183 days or more during that year [SC1][SC2]. A sojourn is temporary presence; consecutive days are not required. Any portion of a day spent in Canada counts as a full day.

The 183-day rule operates as a legislative backstop. An individual with no significant residential ties -- no home in Canada, no spouse or dependants here -- can nonetheless be deemed a Canadian resident solely because they spent enough days here during the year. A foreign consultant working multiple short contracts in Canada, or a retiree wintering partially in Canada, may trigger deemed residency without intending to establish any ongoing connection.

Deemed residents under the 183-day rule are taxed on worldwide income. Because they are not connected to a specific province or territory, they pay federal income tax plus a federal surtax of 48 percent of basic federal tax in place of provincial income tax -- unless they also earn income through a permanent establishment in a particular province [SC2]. Deemed non-resident status can override this result where a tax treaty applies, as described below.

How do tax treaties create deemed non-resident status?

Canada has bilateral tax treaties with more than 90 countries. Where an individual qualifies as a resident under both Canadian domestic law and the domestic law of a treaty country, the treaty's tie-breaker rules resolve the conflict. Subsection 250(5) of the ITA provides that a person who would otherwise be a Canadian resident is treated as a deemed non-resident if, under an applicable treaty, they are a resident of the other contracting state only [SC3].

The OECD model tie-breaker hierarchy -- reflected in virtually all of Canada's treaties -- works through these steps in sequence:

1. Permanent home: resident of the state where a permanent home is available; if in both, proceed to step 2.
2. Centre of vital interests: personal and economic relations closer to one state (family location, employment, business interests, social ties).
3. Habitual abode: the state where the person customarily lives.
4. Nationality: the state of citizenship.
5. Mutual agreement by the competent authorities of both contracting states.

A deemed non-resident is not exempt from all Canadian tax. They remain liable for Canadian income tax on Canadian-source income -- employment income earned in Canada, income from a Canadian business, rental income from Canadian property, and gains on taxable Canadian property.

What income tax do Canadian residents owe and at what rates?

Factual residents and deemed residents are both taxed on worldwide income -- employment, business, investment, capital gains, and any other source globally, regardless of where the income was earned or received [SC4]. Provincial and territorial income taxes are layered on top of federal rates, with combined top marginal rates reaching approximately 53.5 percent in Ontario and British Columbia for 2025.

For the 2025 tax year, federal income tax brackets (per Canada Revenue Agency and PwC Tax Summaries) are [SC4]:

• 14.5 percent on the first CAD 57,375
• 20.5 percent on CAD 57,376 to CAD 114,750
• 26.0 percent on CAD 114,751 to CAD 177,882
• 29.0 percent on CAD 177,883 to CAD 253,414
• 33.0 percent on income above CAD 253,414

Double-taxation relief is available through foreign tax credits. A resident who earns foreign income that has been taxed abroad claims the credit on Schedule T2209, reducing Canadian tax by the lesser of the foreign tax paid and the Canadian tax otherwise attributable to that foreign income. Canada also allows treaty-based exemptions or reduced rates for certain categories of foreign-source income under applicable bilateral agreements.

What is departure tax and how is it triggered on emigration?

When an individual ceases to be a Canadian resident and becomes a non-resident, ITA subsection 128.1(4) imposes a deemed disposition of most capital property at fair market value immediately before the date of departure [SC5]. Any resulting capital gain is included in income on the final departure-year T1 return and taxed at standard rates. This is the mechanism commonly called the departure tax.

The rationale is straightforward: Canada taxes the gain that accrued while the individual was a Canadian resident, before the individual moves beyond Canada's jurisdiction. The deemed disposition does not require an actual sale; the individual is treated as having sold and immediately reacquired the property at fair market value.

Assets excluded from the deemed disposition include: Canadian real property (taxable Canadian property, subject to tax on eventual actual disposition); registered savings plans (RRSPs, RRIFs, RPPs); a principal residence to the extent the principal-residence exemption applies; Canadian resource and timber resource properties; and, under certain conditions, property that was owned when the individual first became a Canadian resident if their Canadian residency in the preceding 10 years totalled 60 months or fewer.

Three forms are required on the departure return:

• Form T1161: Discloses all property with aggregate fair market value above CAD 25,000 at departure. Late-filing penalty is CAD 25 per day up to CAD 2,500.
• Form T1243: Reports deemed-disposition gains and losses.
• Form T1244: Elects to defer payment of departure tax until the property is actually sold. Security must be posted with CRA if federal tax owing exceeds CAD 16,500 (CAD 13,777.50 for Quebec residents due to the Quebec abatement) [SC5].

The departure T1 return covers income from January 1 of the departure year to the departure date. A separate non-resident return may be required for Canadian-source income earned after the departure date.

What are Forms NR73 and NR74 and when are they used?

The CRA offers a voluntary residency-determination service through two forms. Form NR73 (Determination of Residency Status -- Leaving Canada) allows an individual who has left or is planning to leave Canada to request the CRA's written opinion on whether they remain a factual resident, are a deemed resident, qualify as a deemed non-resident under a treaty, or are a non-resident [SC6]. Filing is entirely optional; there is no legal requirement to request a determination.

Form NR74 (Determination of Residency Status -- Entering Canada) serves the mirror function for individuals arriving in or entering Canada who wish to confirm whether they have become a factual or deemed resident.

The CRA's response to either form is an opinion, not a binding ruling. The response may be subject to more detailed review at a later date, particularly if facts change or subsequent audit reveals information not disclosed in the form. Despite its non-binding nature, an NR73 opinion carries practical value: financial institutions, pension administrators, and Canadian payors sometimes require written documentation of non-resident status to apply treaty withholding rates.
