thanks for your reply but i heard that if you are in CANADA for more than 2 years then PR application process faster then any other country.
Hmmm... well, I'm not sure what you mean. CEC applications are processed relatively quickly, but you have to have 2 years of work experience (not simply residence) in Canada to qualify.
Currently, the only FSW streams accepting applications are those with arranged employment (need to continue to be employed by same employer the whole time), and the PhD stream, neither of which seem to fit.
Variations in individual processing time depend on your background and countr(ies) of prior residence, not so much current residence in Canada.
So if my status is valid till december 2013 so i can stay in CANADA even though i dont have any job.
This is true, you may remain until the expiration of your work permit. But you cannot work - and if you leave Canada temporarily and try to return, there is no guarantee that you will be permitted to re-enter.
BTW - no employer "creates" a work permit, only CIC does. So an employer has no right to demand anything - s/he cannot demand that you leave Canada nor return the work permit.
