You need to meet the residency requirements for citizenship.
Refer:

Similarly, you need to meet the residency requirements for maintaining PR Status.
Refer:
http://www.cic.gc.ca/english/information/applications/guides/5445EA.asp

Note that residency requirements for maintaing PR and Citizenship are different.
There are ways to maintain your PR status without being physically present in Canada (refer above link), however, citizenship requirements are based purely on physical presence.
