After five years of Canadian immigration, it is stipulated that

Immigration supervision is different from the requirement of having to live for two years in five years.

Living for two years out of five years is to retain immigration status for permanent residents.

You must have lived in Canada for 2 years in each period.

You must live in Canada for three years to apply for naturalization as a citizen. If you become a landing,

Permanent residents have lived in Canada before, and every two days count as one day, which can only be counted as 1 year at most.

That is to say, I have lived for 2 years before landing, which is 1 year; Then you will be naturalized two years after landing.

Qualified. If you have lived for 3 years before, or 1 year, you will have to wait for 2 years before you are eligible for naturalization.
