If I were in your boat I would tread carefully. Implied status doesn't work that way... That 90 days gives you time to try and restore your status that on it's own is not Implied Status that permits you to work.
IF YOUR WORK PERMIT EXPIRES YOU ARE NOT ALLOWED TO CONTINUE WORKING. In order for implied status to kick in you need to submit an application to extend your work permit
PRIOR TO THE EXPIRY of said permit. With that being said, as a PGWP holder without an LMIA or an ITA you are definitely going to be declined.. being declined by IRCC once can cause you major headaches (when applying for PR later).
So again please tread carefully and do your research. Here's the quick FAQ in regards to implied status, but if you want to read the actual regulations go to my next point.

Read section 186(u) but it also references section 201(1). Proving what I mentioned above in regards to implied status and that you can only work on implied status if you apply for a work permit prior to the expiry of your current work permit.

I am not sure which country you from but search for CIC IEC, if your home country in that list you might have a chance, otherwise you can work on implied status for additional 90 days after your status expire. Unfortunately I am in the same situation as you are with my PGWP expiring in FEB 2017 and no hope of pnp or lmia.
