It's been long since u filed your case and they might need to update your file first. They might ask you to provide updated information to update your file i-e Updated police clearance certificate for yourself & spouse if any , fill in Generic application form, Additional family information form (yourself & spouse), Schedule A Background /Declaration form (yourself & spouse), Travel form and Use of a representative form if any. They might ask you to pay visa fee, also to show proof of funds (Bank statement), Copy of passports (bio page only) 4xpassport size photos for yourself and each family member. You will have to post those documents within 60 days.
If you have already sent those information then you might get PPR1 by the end of this month. PPR2 takes 20 to 30 days once they get Updated information chart + Passport copies (bio page only) I mean PPR1 you know what I mean.
To me where you are till visa stamping will take three to four months.
Good Luck.
I would like to add
My application was also submitted a long ago in 2011 and my whole family medicals was done on 10-12-2013
I got email on 05-10-2014 in which i asked to sent Updated info chart along Passport bio page copy only, which i send it within 5 days.
Till now there is no reply from CIC, my medicals are also going to expire within a month
I wonder what will happen next. will CIC will extent my medicals or we have to do Re-medical??
Any advice or experience shared!!!
