What are the physical presence requirements?
To be eligible for Canadian citizenship, you must have been physically present in Canada as a permanent resident for at least 1,460 days in the six years immediately before the date of your application. You must also have been physically present in Canada as a permanent resident for 183 days in each of four calendar years that are fully or partially within the six years immediately before the date of your application.
When calculating your time in Canada:
only the six (6) years immediately before the date of your application are taken into account;
only days you were physically present in Canada after you became a permanent resident count;
any time spent in Canada before you became a permanent resident does not count;
if you became a permanent resident less than six (6) years ago, your calculation period starts on the date you became a permanent resident;
time spent serving a sentence for an offence in Canada (e.g. prison, penitentiary, jail, reformatory, probation and/or parole) cannot be counted toward residence - there are some exceptions.
