Deemed Residency in Canada: The 183-Day Sojourner Rule
The 183-day sojourner rule, the other categories, and how it differs from factual residency
Reviewed by the Fairlight Accounting cross-border tax team — U.S. & Canadian Tax Desks
Deemed residency makes someone a Canadian tax resident for the whole year even without residential ties — most commonly by sojourning in Canada for 183 days or more in the calendar year. Canadian Forces members, government employees posted abroad, and certain family members are also deemed residents, taxed on worldwide income with a federal surtax instead of provincial tax.

The categories (section 250(1))
| Category | Who |
|---|---|
| Sojourners | People without significant ties who sojourn in Canada 183 days or more in a calendar year — any part of a day counts, but commuting days don't |
| Government service abroad | Members of the Canadian Forces (and overseas school staff who elect), federal or provincial employees who were resident just before appointment or receive a representation allowance, and Global Affairs Canada assistance-program workers resident within 3 months before starting |
| Dependent children | Children dependent on someone in the government-service category whose net income is no more than the basic personal amount |
| Treaty-exempt family members | People exempt under a treaty from another country's tax on 90 percent or more of their income because they are related to, or a family member of, a Canadian resident |
Sojourner versus factual resident
A sojourner visits — for example, an American who spends 190 days at a Canadian cottage without establishing ties — and is deemed resident for the entire year (not part-year). A factual resident has ties; a person who moves to Canada mid-year is a part-year factual resident instead.
Taxation
Worldwide income for the whole year; federal tax plus the federal surtax for non-residents and deemed residents — 48 percent of basic federal tax under section 120(1) of the Income Tax Act — instead of provincial tax. All federal non-refundable credits are available, but no provincial ones.
The treaty
An American who is a deemed resident of Canada and a U.S. resident (or citizen) applies the treaty's tie-breaker; if the tie-breaker makes them a U.S. resident, they're deemed a non-resident of Canada under section 250(5) of the Income Tax Act, removing the worldwide taxation.
Frequently asked questions
Can I become a Canadian resident just by staying 183 days?
Yes — sojourning 183 days or more in a year makes you a deemed resident for the whole year, unless the treaty tie-breaker assigns you to the U.S.
Is a deemed resident taxed on worldwide income?
Yes, for the whole year, with a federal surtax instead of provincial tax.
Does the 183-day rule apply to people who move to Canada?
No — someone who moves and establishes ties is a part-year factual resident instead.
Does the treaty help?
Yes — a U.S. resident under the tie-breaker is deemed a non-resident of Canada.
