Canada Tax Residence: the rule, how days are counted, examples

Summary

If you do not otherwise live in Canada but stay there for 183 days or more in a calendar year, the Income Tax Act treats you as a resident of Canada for that whole year. You then pay Canadian tax on your income from the whole world for all 12 months. This is called the sojourner rule. You can also be resident with far fewer days if you have significant residential ties, such as a home, a spouse or dependants in Canada. The Canada Revenue Agency (CRA) applies the rule, and a tax treaty can override it.

Limit: 183 days or more makes you resident, so 182 days is the most you can stay
Period: The calendar year, 1 January to 31 December
A day counts when: You are staying in Canada for any part of the day
Result: Resident for the whole year, taxed on income from the whole world
Law: Income Tax Act, paragraph 250(1)(a)
Run by: The Canada Revenue Agency (CRA)

Who it applies to

Visitors who spend long summers at a cottage or with family in Canada.
Foreign workers and contractors on assignments in Canada who keep their home abroad.
International students whose home and family stay in another country.
Canadians who emigrated and come back for long visits every year.
Remote workers who stay in Canada for some months as visitors.

The rule

Canada taxes residents on income from the whole world and non-residents only on income from Canadian sources. The Income Tax Act does not define residence in full. The courts and the CRA look first at the facts of your life. A person with significant residential ties in Canada is a factual resident. The CRA's guide, Income Tax Folio S5-F1-C1, names three ties as significant: a dwelling place in Canada that is available to you, a spouse or common-law partner in Canada, and dependants in Canada. Secondary ties, such as a Canadian driving licence, bank accounts, health insurance and club memberships, are looked at together.

The day count comes second. Paragraph 250(1)(a) of the Act says that a person who sojourned in Canada for a total of 183 days or more in a calendar year is deemed to have been resident in Canada throughout that year. To sojourn means to make a temporary stay. The rule is for people who are not factual residents: they have no significant ties, but they were in Canada for half the year or more.

The effect is strong. A factual resident who arrives or leaves during a year is resident for part of the year only. A deemed resident under the sojourner rule is resident for all 12 months, so income earned abroad before the first day in Canada is also taxed. A deemed resident pays federal tax and a federal surtax in place of provincial or territorial tax.

A tax treaty can change the result. Under subsection 250(5) of the Act, a person who would be resident in Canada but who is resident in another country under a tax treaty with Canada is deemed to be a non-resident. Treaties decide such cases with tie-breaker tests: first where you have a permanent home, then where your personal and economic ties are closer. The CRA looks at the whole situation, and you can ask for its opinion with Form NR74 if you entered Canada, or Form NR73 if you left.

Why it exists

Canada wants people who use the country for half the year or more to pay tax like those who live there, even when they keep their home somewhere else. A test based only on ties would be easy to avoid by staying in hotels or rented places. The fixed line of 183 days gives the CRA and visitors a clear answer, and treating the whole year as resident removes the reward for planning the dates of income around a long stay.

Counting the days

You count the days you stayed in Canada in one calendar year. The CRA counts every day or part of a day, so arrival and departure days count. The days do not need to be in a row.

List all your stays in Canada between 1 January and 31 December, including weekend trips and holidays.
Count each day on which you were in Canada for any part of the day.
Leave out days on which you only commuted to work in Canada and went back to your home in the United States the same day.
Add the days. With 182 or fewer you are not a deemed resident under this rule. With 183 or more you are.
Separately, check your residential ties. A home, partner or dependants in Canada can make you a factual resident with any number of days.
If you reach 183 days and are also resident in a treaty country, check the tie-breaker rule in that treaty.

How Countr counts it. Countr counts every day on which it sees you in Canada in the calendar year, 1 January to 31 December, and any part of a day counts as a full day. It shows the count against 182 days, the last day before the sojourner rule applies, and starts to warn you 14 days before. Countr is simpler than the law in three ways. It counts every day of presence, while the law counts days of sojourning, so a cross-border commuter will see more days in Countr than the CRA would count. It cannot see residential ties, which can make you resident with few days. And it cannot apply a tax treaty, which can make you a non-resident even above 183 days.

Examples

A long summer at the lake

Bill lives in Ohio and owns a cottage in Ontario that he uses only in summer. In 2026 he arrives on 1 May and leaves on 31 October. That is 31 days in May, 30 in June, 31 in July, 31 in August, 30 in September and 31 in October: 184 days. He sojourned in Canada for more than 183 days and is deemed resident for all of 2026. Because he is also a US resident, the tie-breaker in the tax treaty between Canada and the United States may make him a deemed non-resident, but he has to claim that. Leaving two days earlier would have avoided the question.

Under the line, with no ties

Chloe is a French designer. In 2026 she works on a project in Montreal from 12 January to 30 June and lives in a serviced flat. She counts 20 days in January, 28 in February, 31 in March, 30 in April, 31 in May and 30 in June: 170 days. She has no home, partner or dependants in Canada. She is a non-resident for 2026 and Canada taxes only her Canadian income.

Few days, strong ties

Raj took a job in Dubai in 2025. His wife and two children stayed in the family house in Calgary. In 2026 he is in Canada for only 45 days. The day count is far below 183, but a home, a spouse and dependants in Canada are all significant residential ties. The CRA would most likely treat him as a factual resident of Canada for 2026, taxed on his income from the whole world.

Exceptions

Presence is not always sojourning. The CRA says a person who commutes to work in Canada and returns each night to a home abroad is not sojourning, so those days are not counted.
A person who is resident in another country under a tax treaty with Canada is a deemed non-resident under subsection 250(5), even with 183 days or more.
The sojourner rule is for people who are not factual residents. A person who moves to Canada and sets up a home becomes a factual resident from the day of arrival and is resident for part of the year only.
Some people are deemed residents without any days in Canada, for example members of the Canadian Forces and federal or provincial government employees posted abroad.
A factual resident who leaves Canada stops being resident on the date the residential ties are cut. The CRA says this is usually the latest of the dates on which the person, the spouse or partner, and the dependants leave.

Common misconceptions

“Under 183 days I am never a Canadian tax resident.”: The 183 days are only for people without significant residential ties. If your home, partner or dependants are in Canada, you can be a factual resident with a few days or none.
“If I cross 183 days, I am resident only from that day on.”: No. The sojourner rule deems you resident throughout the whole calendar year, from 1 January, so income from before your arrival is also covered.
“The 183 days are counted over any 12 months.”: The Act counts days in one calendar year. A stay from October to March can give fewer than 183 days in each of the two years, even if it is 6 months long.
“Only working days count.”: The CRA counts every day or part of a day you stay in Canada, including holidays, study days and weekend visits.

Questions and answers

Does the day I arrive in Canada count?

Yes. The CRA counts each day or part of a day you stayed in Canada. Both the day you arrive and the day you leave count as days.

What tax do I pay as a deemed resident?

You report income from all sources inside and outside Canada for the whole year. You pay federal tax plus a federal surtax, and no provincial or territorial tax.

Can I be resident in Canada and in another country in the same year?

Yes, under each country's own law. If Canada has a tax treaty with the other country, the tie-breaker rule in the treaty gives you one country of residence for treaty purposes, and Canada then treats you as a non-resident if the other country wins.

Do I count days differently as an international student?

No. The CRA says days spent at a university or college in Canada count like other days. A student with no significant ties who stays 183 days or more in the year is a deemed resident.

How do I get the CRA's view of my status?

Send Form NR74 if you entered Canada, or Form NR73 if you left. The CRA gives an opinion based on the facts you provide. The opinion is not binding and can be reviewed later.

Does one day over the line really change the whole year?

Yes. With 182 days you are a non-resident taxed on Canadian income only. With 183 days you are deemed resident for all 12 months, unless a treaty makes you a non-resident.
