Hey, you don't actually get implied status with a OWP application unless you currently hold one and are extending it. I recently asked IRCC this question as I also had a similar issue.Yes, he has implied status.
Their response was:
"If you've applied to extend an open work permit that you already hold, you're covered by implied status and should be ok to stay in Canada while your applications are being processed. If you're currently in Canada only as a visitor, you'll have to apply to extend your stay while your applications are processed."
