Don’t know about revoking PR but you should have a very good reason to move out of ON in case of a PNP. It may not create a problem right now but it will affect your citizenship application at a later date. In case of a job related issue it is advised to exhaust all options to find a job and also to show you getting higher pay or better opportunities in another province before moving out of ON. Gather as much documentation as you can in your favour before changing provinces. Good luck.
