Canadian Citizenship Eligibility Checker

Physical presence requirement for applying Canadian citizenship

You (and any minors applying with you, if applicable) must have been physically present in Canada for at least 1,095 days (3 years) within the 5 years immediately before the date you sign your application. To ensure accuracy, we recommend applying with more than 1,095 days of physical presence in case there are discrepancies in the calculation.

If you spent time in Canada as a temporary resident, you may include these periods in your physical presence calculation. Each day spent in Canada as a temporary resident counts as 0.5 day towards your total physical presence, up to a maximum of 365 days.
