Divakar, It is smooth experience. Murad, no idea abt your question.
DivakarP,
I am in same status as you. I visited Canada 3 times. Nobody asked me, what is your status in leaving country while leaving.
While entering in Canada, USA people will not stop you. Canada authority will stop you and ask your status of USA. You will show them USA GC. After that, they will ask your intention to visit Canada. Say, I want to visit friends for 1 week or so.

It was comfortable experience always for me.
Murad, I beleive you should have not any problem. Good Luck.
