I applied for a Study Permit. It's strange how i have been waiting for the past 3 months without any proper update.They tried to confirm your bank statement after you have gotten PPR? How funny. Did you apply for PR?
You don't have to worry though, I know a few people that shared the circumstance as you. They returned some of their passports without visas recently. They claimed they couldn't issue the visa because economic immigrants aren't allowed to travel at this time. They also told someone to reappear for medicals as she had less than 6months validity on the previous medicals. Hang in there or shoot them an email for updates.
