I am father of 4 children, all of them are Canadian citizenships also my wife is Canadian citizenship. I almost have 700 days that I am living in Canada, I did the application of permanent resident card right after I came to Canada in 2020, to renew my permanent resident card I called in Etobicoko they always said that my card is ready but I just have to wait for a email or they would call me for an appointment to get the permanent resident card, now they sended me an email and they requested for my documents for e.g Record of Landing / Confirmation of permanent residence. I have the confirmation of permanent residence that I got it when I boarded in Canada in 2008. Is this confirmation of permanent residence still valid or I have to renew it?
