Finally received my passport request on 20 May!!
applied on 23rdJanuary, received confirmation the very next day, travelled to the US in April, I received a job offer 10 days ago, using webform I sent a request to expedite but nothing happened, exactly one day before receiving PPR I sent an email to
IRCC.COVID-TravelExemptions-Exemptionsdevoyage-COVID.IRCC@cic.gc.ca and received PPR in 24 hours, i dint have any emergency case, just sent the offer letter.
So I would suggest to e-mail instead of raising a webform.
