If you wish to remain only as a permanent resident of Canada, you should physically present in Canada for 2 years out of your next five year period counting from the date of landing.
In order to apply for a Canadian citizenship you should physically present in Canada for 3 years out of the 4 ( four ) year period.
There is no next step until you apply for a citizenship or renew your PR card before its expiry. There is much time ahead to think about this.
