6 years. If you became permanent resident within past 6 years then mention the dates since becoming permanent resident (whichever is more recent)
Read the section 6 under the following link: (I have just pasted some portion from the instruction guide) Make sure you read the guide thoroughly to understand everything better.
Section 6
The relevant period
The relevant period is your residence period (your calculation of time physically present in Canada). This information is used to help make sure you have met the physical presence requirement for Canadian citizenship. The minimum amount of time you need to be in Canada to be eligible for citizenship is 1,460 days within the six years immediately before applying. This means that your relevant period starts a minimum of 1,460 days before you sign your application.
Question 6G
Write all your Canadian addresses for the six (6) years before the date of your application or since you became a permanent resident, whichever is more recent ("the relevant period"), including the postal codes.
If you were residing, employed or attending school outside Canada, you must also list all your foreign addresses, including the postal codes.
Question 6H
Check the box in A and B to indicate if you have worked or studied in the past six (6) years before the date of your application or since you became a permanent resident, whichever is more recent ("the relevant period").
Complete the chart in section C. You must list all your work and education history including English/French language training for this period and must account for each month.
If you were not employed (i.e. you were unemployed, retired, homemaker, volunteering, etc.) you must indicate this under “Work/Education”, and indicate the time period. Do not exclude any period of time during this period. Do not leave this section blank. If you do, your application will be returned to you.
