Implied status for PGWP is the most controversial topic in this forum. Every month there is a heated debate about this. In the end you are the one who has to make the decision to continue working or not.
Here are my two cents: Yes, in my opinion PGWP it is indeed eligible for implied status. That means you DO NOT need to quit your job. I base my opinion in the fact that the PGWP is considered a type of open work permit by any CIC agent or immigration officer that you might speak with.
Also I received an email from CIC stating very clearly the exceptions to the implied status, which are the international youth programs. Here is the full email I received from CIC and I am highlighting the exceptions to the implied status:
"Implied Status - Temporary Residents
As a temporary resident (TR), if you send your application for an extension of your authorization to remain in Canada at the latest on the expiry date of your status, you will be considered in status as a TR until a decision is made on the application. This is known as an Implied Status*.
If you hold a work permit or a study permit, you can continue working or studying under the conditions of your previous permit if you have applied to extend your stay in Canada under the same category. However, if you have applied to extend your stay under another category, you must stop working or studying.
If you leave Canada while under implied status, you may be authorized to:
Re-enter Canada as a TR, if the Case Processing Centre (CPC) has not yet made a decision on your application to extend your work permit. Please note that you will not be permitted to work/study until you receive your new permit. You must satisfy the officer at the port of entry (POE) that you have sufficient means of support. This applies if you:
are temporary resident visa (TRV) exempt;
held a valid multiple-entry visa before leaving Canada; or
travelled only to the United States** and/or St.Pierre and Miquelon by the end of the period initially authorized for their stay or any extension to it;
Re-enter Canada as a worker/student, if the officer at the POE determines that your application to extend your work/study permit was approved by the CPC while you were outside Canada;
or
Apply for a new work/study permit at the POE provided you have the right to do so under the Regulations.
For more information on implied status, please consult the Operational Manual - Overseas Processing (OP 11) - Section 24.
* Participants in international youth exchange programs (e.g., Student Work Abroad Program (SWAP), International Experience Canada (IEC) or Working Holiday Program (WHP)) do not benefit from implied status, unless extending a work permit not initially issued for the time limit authorized by the program.
