Withdraw PGWP outside canada application and apply PGWP inside Canada

[droy007]

I applied for PGWP outside Canada outside Canada since I was in my home country and did not had a TRV to return back.
Yesterday, I got my TRV approved and I want to ask if I can withdraw my PGWP outside Canada application and travel back to Canada to apply PGWP inland.

I am thinking to do this because I can not work as I do not have an implied status. PGWP outside canada is treated as Open work permit application and there is 20 weeks of processing time. On the other hand, I will get WP-Ext if I apply from Canada.
