How do I receive my IRCC mail when I don't have housing in Quebec yet?

You can give IRCC an Ancre address as your mailing address as soon as your box opens, even before signing a lease. IRCC letters, including confirmations, document requests, and appointment notices, are photographed the same day and read by the AI, which flags them as priority. You get the notification wherever you are, in a hotel, in temporary housing, or still abroad. Once your housing is stable, you can either keep the Ancre address going forward or update your file yourself on the IRCC portal.
