Hi Tindaqureshi..
I think you are in the same situation as me. My wife's application for OWP was refused one month back with reason that Spouses of PGWP holders cannot get an OWP. We called CIC and they said that if you reapply with your job letter showing that although you are on PGWP but you are employed at skil level A,B or 0 then your spouse can get the OWP. Instead of reapplying we went to get the process done at the border as my spouse if from a visa exempt country. At the border the immigration officials granted my spouse the OWP valid till expiry of my WP.
I hope our experience helps you. btw we talked to an immigration lawyer before doing this and he was very helpful. I would suggest talking to a lawyer (not consultant) before you decide.
Good luck!
