They will send an AOR (acknowledgement of Receipt). An AOR indicates that the Canadian government/agency has received your application for citizenship and has issued a case file number for the application submitted. If you have provided an email address they will likely send it via that means otherwise it will be by snail mail(i.e regular mail).Hello,
I just sent my Citizenship application last week by regular mail. can you tell me how will IRCC inform me about the receipt? Email? mail?
Location: Hamilton
Application Sent: August 7th
Application Received:
Type of application: citizenship
Physical presence: 1100 days
**Points to note** there is no established timeframe for this since they current have a backlog of files/envelopes to open and acknowledge.
The other applicants here in the forums have an idea that their applications have reached the physical location of IRCC as a result of using courier or express mail. This option has a tracking/signature feature..
Hope this helps. Good luck
