Start with factual or ordinary residence
Canadian residence is not defined by a single annual day threshold. The Income Tax Act says that a reference to a person resident in Canada includes a person ordinarily resident there, and the CRA describes factual residence as an all-facts question. Relevant facts include where a person normally or customarily lives, the continuity and purpose of stays, and residential ties inside and outside Canada.
That factual or ordinary residence review comes before the deemed-residence day gate. The CRA folio says subsection 250(1) does not apply until it has been determined that the individual is not factually resident. A person can therefore be factually resident because of their settled pattern of life and significant residential ties without reaching 183 qualifying days in Canada.
Review significant residential ties as facts
The CRA identifies a dwelling place, a spouse or common-law partner, and dependants as ties that will almost always be significant. Their meaning depends on the circumstances: for example, whether a dwelling remains available for occupation and whether family members remain in Canada. The review is not replaced by a passport stamp total.
Secondary ties can also be relevant when considered collectively. The CRA lists matters such as personal property, social and economic ties, licences, health coverage and professional memberships. These are evidence in an all-facts analysis, not points that a calculator can add into a residence score. The significance of any tie can differ when a person enters, leaves or maintains a life abroad.
Use 183 days only as a later statutory gate
Paragraph 250(1)(a) addresses a person who sojourned in Canada for 183 days or more in a calendar year. It is a deemed-residence path for someone who was not already factually resident. The 183-day figure is not the definition of Canadian residence, and ordinary physical presence is not automatically the same as a qualifying sojourn.
For the same reason, fewer than 183 days is not proof of non-residence. A total below the gate can show only that paragraph 250(1)(a) is not reached on the confirmed sojourning days reviewed. Factual residence may still exist, other categories in subsection 250(1) may apply, and the quality and timing of residential ties still require their own analysis.
Keep treaty and personal tax conclusions separate
After a domestic basis has been identified, subsection 250(5) can create a separate treaty layer. It may deem a person not resident in Canada at a time when that person would otherwise be factually or deemed resident domestically but is resident in the other country and not Canada under an applicable tax treaty. The particular treaty and all relevant facts control that inquiry.
A presence ledger can organise dates and test a limited upper bound for the 183-day path. It cannot determine factual residence, a treaty tie-breaker, part-year treatment, filing obligations, filing status or tax liability. Special subsection 250(1) categories, including specified government, forces and family situations, also remain outside the estimator and require review against the current law.
- Factual or ordinary residence and significant ties come first.
- The 183-day path is a later deemed-residence gate, not the residence definition.
- Treaty residence is a separate layer after the domestic analysis.
