How does Canada decide tax residency?
Canada uses residential ties, not a single day count. Significant (primary) ties, a home in Canada, a spouse or common-law partner in Canada, or dependants in Canada, generally establish factual residency on their own. Secondary ties are weighed together. Separately, 183+ days in a year makes you a deemed resident.
What is the 183-day rule in Canada?
If you 'sojourn' in Canada for 183 days or more in a calendar year, you're generally a deemed resident for tax purposes, taxed on worldwide income, even without significant residential ties, subject to any tax-treaty tie-breaker.
What are significant residential ties?
The CRA's three primary ties are: a dwelling place available to you in Canada, a spouse or common-law partner in Canada, and dependants in Canada. Any one of them strongly indicates factual residency.
Can a tax treaty override Canadian residency?
Yes. If you're a resident of both Canada and a treaty country, the treaty's tie-breaker (permanent home, centre of vital interests, habitual abode, nationality) decides which country taxes you as a resident.
