sorry to hear the rejection to your case madam prabjot.
Before you apply for appeal or reconsideration, as some one suggested work on the root cause,
In my opinion -
As you have mentioned that you have 5 yrs of exp and applied under IT Manager, you should consider that it will take you lot of efforts to prove that you were actually doing the PMs work, not just lil team management or working on RFPs or SoW.
Pl note that PMs in north america are with wealth of exp in technology and management. They will be evaluating you against current PMs lot in canada. You can do your self some research in canada job market and see the job ads for PMs ( you won't find very often PM required with total 5 yrs exp)
Also pl note, they don't need developers under NOC 0213 cat... They have become lot strict post 26june 2010 in their old case evaluation as well.
I can only wish as others did, good luck for your preparation in appeal procedures. But just don't overlooked the reality, we all know in India million of people works as PM ( only designation , they may not be doing whole project management -as mentioned in NOC 0213) with 5-8 yrs of exp. You may not be the one, but to satisfy VO there has to be different approach and presentation.
