Thank you for your answer.
Let's give an exemple to understand
For exemple pr got on January 2020(expired on January 2025), I met the residency requirement more than 730 days, I renew my pr on 2025 (expired on 2030) During this period (2025-2030) I stay in Canada just for 300 days, so I didn't meet the residency requirement, do I can complete the 730 after 2030 and apply for renewal or not.
Thank you for your patience.
No, you would NOT have met the R.O.
A PR needs to meet the R.O. of 730 days in every 5 year `window'.
Here's more info:
https://www.myconsultant.ca/EN/The-Residency-Obligation-for-Permanent-Residents
Paragraph 28 (1) and subparagraphs 28 (2)(a)(i) of the Immigration and Refugee Protection Act (IRPA) state that a permanent resident must meet his/her residency obligation
for each five-year period by being physically present in Canada for at least 730 days.
The “two-years-out-of-five” rule may seem simple at first, but it is rather complex. Most people take the five-year periods as discrete five-year periods. However, according to para.28(2)(b) of IRPA, t
he five-year periods for residency obligation are rolling periods. This is a vital distinction because,
for example, while there are only two separate five-year periods in ten consecutive years,
when counted in a rolling manner there are suddenly six of them —12345, 23456, 34567, 45678, 56789, and 678910. Legally speaking, a permanent resident may have to be present for at least 730 days in Canada in all six rolling periods within those ten years if he/she is absent from Canada frequently.

Does that clarify what you need to do to maintain your PR status?
