That's correct.... and the reason your application got delayed then other PGWP is because of the restoration as it changes the category you applied for as it is considered as restoration application... don't worry you will get a reply in few days..I just paid the restoration fee and attached it with a LOE. On my ircc account it says we are reviewing your eligibility. And yesterday i just got a mail from the government saying that you study permit has been approved and a document has been sent. But it was issued only for a day.
though wait until you get the work permit approved before you start working again... also the reason you got just 1 day approval for study permit is they restored you as a student so they can process the work permit.....
