Mine also same file approved June 8th AOR but I am not travelling to anywhere but waiting PPR to COPR Procedure. FYI, once PPR email sent you will have 30 days time to complete the COPR process else the concern application will get rejected automatically.
Web-form usually takes about 2 weeks to update minimum. By the time, I believe you' d receive an PPR email. If you have, valid status like work, study permit to entry back would be fine to travel. however, as its crucial time to complete final stage.
Its kind of little complicated at this point. what happen if the web form takes more time to update instead of usual 2 weeks as we all know how CIC works! its always a Myth. I wouldn't take this risk unless if its a real emergency.
If you still want to, better attach a LOE with your Web-form why do know want to go for? because, it makes your file complicated as the works done inside the country as Inland applicant. I don't know how they will process just for landing procedure in other country that's whole new process. Inland and outland applicant totally 2 different thing. Call CIC agent to ask your query or spend some money to good immigration lawyer for 30 minutes appointment. Hope, this will help little better.
