1095 in 3 out of 5 years from the day before applying.
each day you were physically present in Canada as an authorized temporary resident or protected person before you became a permanent resident counts as half a day (up to a maximum of 365 days);
each day you were physically present in Canada after you became a permanent resident counts as one day;
So basically you need at least 2 years of physical residence after the PR (Date of CoPR). And up to 2 years (counted as 1 year) of physical presence before getting PR.
