Adding spouse to PR application in progress

[OrangeBlue]

Hi,

I have been working in Canada for the past 2 years. My PR appication under FSW category is in progress in Buffalo. I got a file number. I got married a month ago. My wife is with me in Canada on visiting visa. I want to add her to my PR application. Could somebody advise me the process to do this? Or where can I get the information about the process? I didnt get any reply for my email sent to Buffalo office.
Any help towards this is much appreciated.

thanks
