@ponga and concerning extending the OWP and implied status. in terms of implied status it is very clear from CIC website that once you apply to extend your status you get implied status which would automatically allow you to keep working. there is nothing that states that you can't keep working, one way to confirm that is if someone has PGWP and then apply to get sponsored under canadian experience program, it is clear that they will get to continue working while their application is being processed.
from CIC website:
I have applied for a new work permit. Can I stay in Canada if my work permit expires?
Yes. You can stay in Canada, and may be able to keep working, under what's called implied status. That means the law implies you are a temporary resident. The implied status lasts until Citizenship and Immigration Canada (CIC) decides on your new permit application. However, you must respect the following requirements:
If you applied for another work permit
You must stay in Canada and meet the conditions of your original work permit. If you applied for a work permit extension before your work permit expired, you can keep working under the same conditions as your existing permit until CIC decides on your application unless you have applied to extend your stay under another category.
If you applied for a different kind of permit
You cannot do any of the activities allowed by the original work permit. For example, you may have come to Canada as a worker and then applied for a study permit. If so, you must stop working once your work permit expires. After that, you cannot work or study until you get a new permit.
