My file was with Ottawa, Canada. When I travelled to India and raised general web form to prioritize, IRCC knew that I travelled to India and not present in Canada. They transferred my file to New Delhi VO and send an update in my account about that.
Visa exempt cases are now prioritized by emailing
IRCC.COVID-TravelExemptions-Exemptionsdevoyage-COVID.IRCC@cic.gc.ca, it will take 2-3 weeks to get passport request if they find your case valid. You will not get any other reply from this email apart from an auto reply. Alternatively you can also use the webform @
https://secure.cic.gc.ca/ClientContact/en/Crisis. Both works the same way. Hope this helps.
