You remain a permanent resident of Canada until CIC says you are not, whether you renew your PR card or not. The PR card just enables you to travel and re-enter Canada by commercial means (plane, boat, bus, etc). It is the COPR (confirmation of permanent residence) that confers PR status - that paper you had to sign infront of a CIC officer/border agent the day you did your landing and they gave you a copy.
That said, if you don't meet residency obligations (i.e. spend at least 730 days in Canada in every rolling 5 yrs), you may loose your PR status. Have you spent 730 days(2 yrs) in Canada between March 2010 to March 2015 (that is the last 5 yrs)?
a) If yes, you can consider renewing your PR card because you are following the rules. Ensure you attach proof.
b) If no, then applying to renew your PR card is a risk, because chances are they will find out you haven't met residency obligations and begin proceedings to revoke your PR status. If that happens, you have a right to appeal (I believe you have 30 days to file appeal) and try to show why they should allow you keep your status. You will need strong humanitarian and compassionate grounds to be successful. Unfortunately, I don't believe moving to the US to be with your husband, etc will be enough.
The other option you have (if you have not met residency obligations), is to try to enter Canada in a private car (e.g. rental) using your COPR document(it never expires) plus your passport. If you are lucky, the border officer may let you enter without reporting you. If you succeed, you must remain in Canada for 2 yrs straight(no leaving for any reason) then you will be back in the good books again and can renew your PR card.
The other thing to note, you must remain a PR up until the moment you become a Canadian citizen. So it's important that your residency isn't called into question. Goodluck!

Thank you for all your advice. I am trying to check in cic website as much as I can found out this. If I dont extend my PR card, can I still be residence of Canada. I lived in Canada 3 years and 10 months as permanent residence. Just a few days missed when I went for vacation to US. Please advise me again on this. Very sorry to bother you and thank you so much.
Here is the link that I found :
