А если быть более точным, то через три года из пяти, которые Вы прожили в Канаде.

You must be physically present in Canada as a permanent resident for 1,095 days within the five (5) years immediately before applying for citizenship.

Only the five (5) years preceding the date of your application are taken into account. Within that five-year period:

• Every day you spent in Canada as a permanent resident counts as a full day.
• Every day you spent in Canada as a temporary resident or protected person before you become a permanent resident counts as a half day, up to a maximum of 365 days. Therefore, in order to get the maximum 365 day credit you need to be physically present in Canada as a temporary resident or protected person for 730 days during your eligibility period.
• Time spent serving a sentence in Canada does not count towards the physical presence requirement (i.e. you cannot count time spent serving a term of imprisonment, probation and/or on parole, as physical presence).
