Changing Province problem, is that possible?

Hi my situation maybe unique.

My aunt has lived in SK for long time. In the year 2010 I came to SK to continue my graduate study on study permit. After I came here I heard about SINP program and I applied it under family member category. I'm now a full-time graduate student in SK.  I'll graduate this year and I've got the SK nominee but I haven't submitted my PNP documents to CIC yet.

Overall, my case is:

1. Have had nominee but not submitted to federal government yet.
2. Have stayed in SK for two years on my study permit.
3. Maybe find job outside SK before I get the PR.

So my question is if I find job outside SK before I get the Immigration VISA, should I report to CIC to cancel my PNP? Or I can still use my PNP PR to land in SK but work outside? Or what if I got the PR and soon after that I find job outside SK?

Thanks a lot for attention, and your help will be so valuable for me.
