Did you get a work permit? Atleast maybe this will expedite the arrival in Canada and just wait for the approval of the PR, I don't know if that works.Your case same as me but I'm outland. Received PR application: 19 July 2019, AOR: 21 Aug 2019, medical pass: aug 2019, pre arrival: 05 sep 2019, no document request. But now for almost a year, no any news. So tired & feel hopeless although IRCC still inform "we're processing your application".
